My dad once had a special base receiver that he called a "CB" but it wasn't a "CB", it was way bigger. He used it as a CB, but when he turned whatever dials he could pick up the signals from Wright Patterson Air Force. Of course, the antenna was pretty high up. One time while he was talking, he was interrupted by Wright Patterson who told him to immediately remove himself from that band.

Hey Matt great video. I would just like to note that air traffic control is on frequencies 118.000 - 136.975 108.000 - 117.975 is aviation navigational radio. I believe all other information is correct. Thanks!
I have a dongle made by RTL-SDR, and it is indeed buckets of fun to listen to signals! I can pick up police, fire, ems, Ham radio, aviation radio, and of course pagers in Southern Idaho. I may or may not have decoded hospital pager data, which of course is Very Illegal in the U.S. from what I understand.
Don't know if it's illegal to decode it, but I definitely think it's illegal to share the decoded data. That data has a lot of PII (personally identifiable information) on it.
One thing an analog scanner cannot pick up is data. Ham radio is in a new era when computers are being used. I remember picking up hidden signals off the large satellite dish, and a long, medium and shortwave receiver. Subcarrier signals ruled the satellite dish. Now with computers signals are endless. Thanks for video.
Although I do sometimes squelch the static, I grew up with analogue variable capacitors tuning a tank circuit to receive RF signals. Thus, I grew up hearing the white noise produced by the big Bang and appreciate it. One can pick out extremely weak signals from an open squelch. Sometimes, with the squelch on, the extremely weak signals can not be heard.
Good question. His signals are off the chart. Remember he is a ham radio operator and I bet he has many multiple antennas and accessories. I got the bundle with antenna I still cannot hear anything except VHF/UHF when someone local is there or FM. I think you will need a good multiband out door antenna.
The Ham band you showed sounds like Packet radio for Ham Tx/Rx that you hooked up through your computer. I remember seeing it working back 1994 when I was in Phoenix, AZ while attending DeVry University. That was also when I got my Tech/no code license my callsign was at the time was KC7GHJ. I still have the original but I am sure it is dead since that expired in 2004.
Thanks for this video. I was an Infantry Signaler back in the 70's and used an A13 Larkspur that operated between 2-8Mhz. Do you know of a low-cost SDR that can work on these frequencies? This RTL SDR doesn't seem to.

Hi Matt. I primarily frequent retro computer channels but this video showed up in my suggestions and I enjoyed the video very much -- very interesting content and production quality is excellent. I'm in the same small TH-camr position as you, with about the same number of subscribers. For what it's worth, count me in as another sub to your channel.
What's the best all in one budget kit for a noob who just wants a taste of SDR to see if they want to go further. Somebody who doesn't know anything about antenna types and sizes, etc. What is the entry price for that? I see that the SDR you use is about $25. How much is an antenna and which one to get?
Yes, there is, particularly where the key is poorly chosen ... but it is highly illegal and I will not go into details. Also, monitoring or republishing POCSAG messages.not intended for you is also highly illegal _(Wireless and Telecraphy Act - Interception of Telecommunications - and corresponding criminal offences in other jurisdictions)_
I have a rtl stick here with same software. However you have a much cleaner signal. Very low noise level. But you are probably using outdoor antennas, instead of me use the default antenne that came with it, indoors...
Definately use a dedicated antenna tuned for the band you are listening to. I have some outdoor antennas but I use some indoors also. For ADS-B I can use a portable cellular antenna indoors and get about 200 miles, sometimes more. If I take it outside I can get TX, LA, a small piece of MS and almost AR from SE Texas. I haven't found any other antenna that does that so I stick with it. But thats why you use a tuned antenna.
for starting out or a quick blast sdr sharp is ok, but once you get set up and get into it you will find it can be quite deaf(cannot get signals it should), another program is hdsdr but that can be a bit of a pain to set up. as someone who uses sdr, i recommend a program called sdr pro, it is easy to find and use.
One thing you left out was that when connecting RTL 1090 to the SDR work on seeing planes as longs as they have transponder on. Lots of air craft such as military will turn off their transponders for many reasons. It doesn't actually turn your PC in to a radar station as it never transmits only receives.
That's true. One thing that will come about in 2020 is the requirement of all aircraft (I'm sure military will be excluded) to use this beacon either 1090 mhz of the one in the 900 mhz range.
With two SDR receivers yes you can :) or you could purchase an SDRPlay RSPDuo which can do both with one device. If you take a look at one of my SDRPlay videos I show exactly how to do it with a RSPDuo
Just got my RTL-SDR V4 yesterday and with the help of this excellent video was running tracking aircraft in about 30 minutes! (For some reason lib-usb wasn't bundled but was easily found on the web and dropped in the rtl1090 directory)
Many hacks, tweaks, and firmware/software tools for these R820T2 (and earlier R820T) tuner chips can extend frequency bands/ranges for the part which have simply been "locked out" to comply with FCC/government rules (to keep certain radio traffic away from common consumers). These cheap chips typically have a cheap piezo which drifts during sustained use so you need to install a temp-controlled oscillator (or cooling bulk) to do anything half-serious. A really neat little gizmo but don't expect high-end radio fidelity from a $20 dongle.
Yes, there are linux alternatives for basically every software he used. You might be able to listen to police radio, it depends on if it's encrypted or not. Check rtl-sdr.com
how do you get such good reception? i used several amateur radio antennas and i can get fm broadcast radio, i have heard some, very little air traffic. i have a nooelec sdr and i can't get any ham radio stuff, wwv, i can tune on one of my ham radios, and hear all this stuff perfectly. what am i doing wrong, or what are you doing to get this magic?
is there software to run this on a macbook. The last SDR I had was useless on my macbook. What IOS is required. No one ever tells you this info in their ads.
What is the frequency coverage for this device and does it plug too s computer or a smart tv? Wondering if it could be used for a spectrum analyser or other type of radio test equipment? RJL
Interesting video, I would be interested in a follow-up video that shows the antennae you used for each of these applications. Antenna design is something I hadn't given much thought to until I tried SDR for 1090MHz for FlightRadar24 - for the first attempt I connected it to my TV aerial which worked absolutely fine... in a very narrow arc of sky!!! Yes, a highly-directional antenna for an omni-directional application! I then found instructions for a homebrew 8-element colinear antenna on the net, built that and it worked so much better.
There's nothing like a properly tuned antenna for the given frequency that you wish to receive. Coliears are good because they can be quite wideband for the given frequency they are designed for which gives you some margin for error when homebrewing antennas. 1090Mhz is such a tiny wavelength so the antenna doesn't have to be big at all. I can cover antennas in a video as I have built many over the years, but I'll have a think about what content to have. Thanks! :-)
What about drone (dji) communication data. Like whether to go forward or back, up or down, their video link. That kind of stuff? Can it visualize that sort of data?
i know that it is a little topict could a software defined radio be used tn conjunction with an array of broadcast antennas and a small transmitter to map metal detection in a small area providing info that a standard metal detector could not?
I couldn’t answer that 100% as I have no experience with that, but an SDR receiver can receive on a wide range of frequencies, so if you knew the frequency to look for, and recognised what was being picked up, then possibly. Do you have any links or more information on this subject?
my bad the way most metal detectors work is to send a big signal out then quickly switch to using the antenna as a receiver and look for interference with the signal it sent out they use a number of frequencies so while i could find out they will likely be low frequencies it has just struck me that a computer crossed with a metal detector had possibilities sdr modules are half the battle.
I’m not entirely sure about grib files. However, you can most certainly receive weather faxes from orbiting satellites. I’m i the process of creating a new video which may cover this. Thanks for watching :)
Tech Minds There are freewares, UGRIB for ex, but they require a download from the web. It would be special to use this in areas too far from shores. Im rooting for you👍 Ordering the hardware soonest. Thank you for the vids!!
Derek O'Brian Thank you for doing this research. I now have the hardware in hand, next is the time. Hopefully this weekend. I have an ssb isolator in my standing rigging. Going to attempt w small antennae that came with, then connect it to the ssb antennae to the diff, which may be necessary. Will keep you posted soon. Thank you again!!
there exist other videos on youtube on how to recieve recent NOAA satelite data (of different varieties) with an SDR and DIY better arial. like this one: th-cam.com/video/cjClTnZ4Xh4/w-d-xo.html
Well, it depends on what the resonant frequency of the antenna is. Normally, the higher the frequency the small the antenna, unless it's a dish of some kind. But that antenna could be loaded, which means its trapped for other bands. So saying just a small antenna we could not be accurate at which band its meant for. It WILL however, be for anything 50 Mhz and up. Anything below 50/30Mhz normally would entail having a long piece of wire. Best thing to do is plug it in, and see if you can pick up anything around 100 Mhz (for Broadcast radio) then between 144 Mhz and 148 Mhz, then 430 Mhz upto around 440 Mhz. If you find you are not receiving much, invest in a multiband antenna, like a discone: amzn.to/2HMnMty or maybe something like: amzn.to/2GK0g0U However, you can always just try a really long piece of wire hung up over a tree for example which would be perfect for anything below 30 Mhz.. Assuming your SDR can go that low (normally a UpConverter is required) depending on the SDR you have.
Depends where you live for police scanning. In the UK, where I am from, they are encrypted and digital, where as I believe in some states in the USA you can listen in using an SDR. Take a look at www.radioreference.com for information on local tranmissions. Might give you an idea of what frequencies are local to you.
I liked that video simply for the summary at the beginning. I wish more TH-camrs would do that. (Would be even better if you had the timestamp for each bullet points)
Its is possible, I have connected my SDR receiver to a Raspberry Pi and used KODI with a PVR plugin. I will do some research on Windows Software too and possibly make a video on it. Thanks!
I want to catch hold of unknown frequency and for that do I need wideband? And if yes then what sort of sdr recvr do I need for that? Or can I get it using some software is the solution please let know the software to download?
How to receive weather satellite pictures? With the AOR3000a it was possible when adding a printer. Is it possible to show the weather satellite pictures on a computer using a SDR?
@Mudkip909 thanks I first need to get it working again I thought maybe mine was broken and purchased a new one Unfortunately this one gives same error🙁
It's a Digital type of modulation, much like DSTAR, P25 etc etc etc :-) If you want to listen to more DMR search google for DMR Hoseline, it's a website which streams DMR Ham reflectors in real time.
Hi friend.. Thanks for the help last time I have bought at 100Khz-1.7GHz Full Band UV HF RTL.SDR+USB. And ran it through a dsd+ but it all I seem to get is just white noise. Not sure why just wondering if mite know cos am new to all this.. Any info would be very appreciated.. Thanks pete
I have tried using Nooelec SDRs, but the noise level is so high I cannot hear anything. I have an up converter as well and attached all of my Ham band antennas and it is still too noisy. After several weeks, I finally gave up and put them away. Thanks for sharing your successes with your SDR. 73 - de Mick, WB4LSS
Hi Mick, thanks for the comment and watching my video. It could be possible you have some Local QRM or maybe a faulty SDR. I have a couple of NooElec dongles and the more expensive one is definitely better with regards to sensitivity and noise.
Tech Minds - I have had mine for three or four years and couldn’t tell any difference between the high-end Nooelec and a cheap $8 dongle. I rarely see peaks above the noise level and those are mostly some sort of digital transmission. I may give it another try some day. Thanks for your reply! - Mick
Mick Bradford If you plug your TV aerial to the SDR you will likely hear a lot more. I spent weeks with the ANT500 but it was just so weak I gave up. You could also use an android phone or tablet and connect through an OTG cable which will give you the ability to move outside at higher elevation which may help
Play around with the RF gain,and disable the automatic gain control. IME it cranks the gain WAY up,and just raises the noise floor to the moon. I get much better results adjusting it manually.
if your a ham then you can build circuits and stuff, get a hammond aluminium project box, and install the dongle into it, take off the usb plug and hard wire a "proper" screened usb lead to the board, desoldering the antenna socket and soldering on a coax with a bmc plug fitted to the box will help, lastly put clip on ferrite's on both leads as close to the box as you can. turn off the auto gain(net searches will show you how), and set the gain slider to 3/4 manualy . this works but only if noise is a problem, most times they work out of the box, it has to be said some dongles are poor(quality control issues), as they cost nothing its best to buy two or three at a time chances are you will get a good one. this is only for those with noise issues.
How do you connect an antenna to the SDR? And since it covers such a wide range of frequencies, wouldn't you need a large array of different types of antennas?
Good question, well, all SDRs have an antenna connection, some even have 2 or more antenna connections. You can buy mulitband antennas, say for 50MHz and below, and then get another type of dual band antenna for VHF and UHF
For this SDR, any antenna with a Micro SMA connector will do (even just a stretch of stripped coax will do!) A variety of various band antennas _can_ get you the best response, but even the antennas shipped with the kit does great!
Normally CB's are around 27Mhz and planes are around 120mhz, pmr446 is around 446Mhz, so as long as you have the correct antenna for these frequencies then yes, you can most certainly receive them :-)
Tech Minds MHz? So cuz I. Have a uv5r radio I’m just used to uhf and vhf idk what MHz kinda is ? Basically it’s the same right? Like example pmr446 channel 3 would be 446.000 whatever the end thingy is MHZ ? I’m new so idk antennas really but like things I really want to listen to is yeah airplanes cb truckers security pmr446 channels and all that There’s one of these on amazon what comes with 3 antennas but I really don’t know what antennas I’ll need for things I want to listen to I just like listing I ain’t read up on these things lol as I don’t get the antenna my uv5r I just use 1 antenna for all I’m guessing cb I’ll need a different antenna but vhf And uhf I can use same antenna? Only thing I heard is for cb I need a uh proper setup ? But I kinda want it portable Here’s the one on amazon comes with 3 antennas or 2 could you tell me if I can pickup things I want? www.amazon.co.uk/NooElec-NESDR-SMArt-Enclosure-R820T2-Based/dp/B01GDN1T4S/ref=sr_1_3?ie=UTF8&qid=1523207477&sr=8-3&keywords=rtl+sdr&dpID=41K47sRgu%252BL&preST=_SY300_QL70_&dpSrc=srch
Can somebody tell me if this works for listening radio in analog ways? and if works too for searching catching up the signals from a rf remote for example? thanks in advance
You need to download the plug in from the link in the video and place the DLL file into the SDR# directory. Alternatively you can use DSD+ from the command line without the sdr# plugin.
Great videos. I've always been fascinated by radio and what can be achieved it with modern tech in this regard. One thing, I bought one of the USB receivers and although it works well to pick up commercial FM with the antenna supplied...can you recommend a more powerful indoor antenna at all? Some of us can't mount antennas externally and it'd be great to be able to pick up some air traffic and HAM radio. As it is with this basic kits, you're basically just getting a basic radio and won't be able to listen to most of the things in this video. (correct me if I am wrong, I am still a noob at this!)
Indoor antennas are kinda hit or miss, unless you have access to your loft space. If so, then I would recommend installing antennas in your loft if you cannot access outside.
Absolutely correct! I am a UK based Ham Radio operator but as this video reaches all corners of the globe I wasn't being specific with regards to the frequencies. :-) Thanks for watching!
This video is about listening to radio transmissions, no band restrictions apply. If you are going to transmit, then you need to know your band restrictions and the band plan for your area.
That thing has a very high nose floor. The squelch will help a little... maybe. If the signal you want to hear is high enough above the noise floor. Otherwise it just turns everything down.
Thank you for the video. I was given an RTL SDR for Christmas and I'm looking at ways to use it, and this video is very useful, I'll have to try out a few of these things. Good Luck on your youtube quest. I am in the same boat as you. I run a small niche channel that earns enough to pay for itself, but they want to take that all away now. I'm not in it to get rich, but to them that doesn't seem to matter anymore.

I got one of these but couldn't do much with it, I think it was due to the aerial I was using, just the one that came with the Rx. I'd be interested in knowing about better aerials.

Somebody who doesn't know anything about antenna types and sizes, etc. What is the entry price for that? I see that the SDR you use is about $25. How much is an antenna and which one to get?
Are you able to decode DAB signals with this?
Yep sure can with the right software, will do a video on this at some point
@@TechMindsOfficial Great Look forward to it
4:19 And when digital signal is encrypted? Are there some ways to get it?
Yes, there is, particularly where the key is poorly chosen ... but it is highly illegal and I will not go into details.
Also, monitoring or republishing POCSAG messages.not intended for you is also highly illegal _(Wireless and Telecraphy Act - Interception of Telecommunications - and corresponding criminal offences in other jurisdictions)_
I have a rtl stick here with same software. However you have a much cleaner signal. Very low noise level. But you are probably using outdoor antennas, instead of me use the default antenne that came with it, indoors...
Definately use a dedicated antenna tuned for the band you are listening to. I have some outdoor antennas but I use some indoors also. For ADS-B I can use a portable cellular antenna indoors and get about 200 miles, sometimes more. If I take it outside I can get TX, LA, a small piece of MS and almost AR from SE Texas. I haven't found any other antenna that does that so I stick with it. But thats why you use a tuned antenna.
Does it do FM HD as well? (the free digital channels of FM radio)
Here in the UK we have DAB, there are DAB decoders available for use with SDR receivers
for starting out or a quick blast sdr sharp is ok, but once you get set up and get into it you will find it can be quite deaf(cannot get signals it should), another program is hdsdr but that can be a bit of a pain to set up.
as someone who uses sdr, i recommend a program called sdr pro, it is easy to find and use.
And NOAA Weather Radio.
One thing you left out was that when connecting RTL 1090 to the SDR work on seeing planes as longs as they have transponder on. Lots of air craft such as military will turn off their transponders for many reasons. It doesn't actually turn your PC in to a radar station as it never transmits only receives.
That's true. One thing that will come about in 2020 is the requirement of all aircraft (I'm sure military will be excluded) to use this beacon either 1090 mhz of the one in the 900 mhz range.
Why does it need a wider bandwidth?
Is it possible to attach an antenna to that device, for people who live in a metal house?
Do you know if you can run two tasks simultaneously? Like say for instance, track aircraft as well as listen to airband radio?
With two SDR receivers yes you can :) or you could purchase an SDRPlay RSPDuo which can do both with one device. If you take a look at one of my SDRPlay videos I show exactly how to do it with a RSPDuo
Hmmm, can you pull a weather fax with this gear? Seems much simpler than getting a shortwave radio, etc, etc.
Never mind, found your next video on this.
Can it show the live signal of Wi-Fi? currently working on a project and I need to monitor the behaviour of the Wi-Fi signal.
Depends on which SDR receiver you use. Must be able to cover either 2.4ghz or 5ghz, depending on which band you want to monitor. But the answer is yes
Tech Minds thanks a lot for the reply.
Can you please give the link to download a plug-in/decoder for DMR to be used with sdr sharp.
Just got my RTL-SDR V4 yesterday and with the help of this excellent video was running tracking aircraft in about 30 minutes! (For some reason lib-usb wasn't bundled but was easily found on the web and dropped in the rtl1090 directory)
Hi bought Rtl sdr v 4. Can you suggest a general easy type antenna to use and is quick to build.
I also wonder anntena infomation!
Many hacks, tweaks, and firmware/software tools for these R820T2 (and earlier R820T) tuner chips can extend frequency bands/ranges for the part which have simply been "locked out" to comply with FCC/government rules (to keep certain radio traffic away from common consumers). These cheap chips typically have a cheap piezo which drifts during sustained use so you need to install a temp-controlled oscillator (or cooling bulk) to do anything half-serious. A really neat little gizmo but don't expect high-end radio fidelity from a $20 dongle.
Can you listen to police frequencies? Like you do in a police scanner? Also, is there a linux version of this software?
Yes, there are linux alternatives for basically every software he used. You might be able to listen to police radio, it depends on if it's encrypted or not. Check rtl-sdr.com
@Mate Varga Thanks.
Not in the UK
how do you get such good reception? i used several amateur radio antennas and i can get fm broadcast radio, i have heard some, very little air traffic. i have a nooelec sdr and i can't get any ham radio stuff, wwv, i can tune on one of my ham radios, and hear all this stuff perfectly. what am i doing wrong, or what are you doing to get this magic?
Can you elaborate the DMR concept with a setup using the software you used?
If you have the appropriate license, can you transmit with software defined radio?
You would need a license to transmit, but SDRs don’t actually transmit, unless you use something like a LineSDR, HackRF, Pluto or a FlexRadio
is there software to run this on a macbook. The last SDR I had was useless on my macbook. What IOS is required. No one ever tells you this info in their ads.
What is the frequency coverage for this device and does it plug too s computer or a smart tv? Wondering if it could be used for a spectrum analyser or other type of radio test equipment? RJL
Absolutely, take a look at my Beginners Guide video, that should provide some useful information for you :-)
The usual frequency coverage is 25 - 1700 mhz. I don't think you can run on a smart tv but there are android apps that will run on a android box.
Just got an RTL-SDR and this was very helpful.
how do i set up my rtl dongle for sdr console or sdr sharp? it doest even find anything in the definitions box
does mode-s contain metorological-related data i.e humidity & temperatureof aircraft enviroment?
How do I get all my settings docked at left like you have? New software (2022) doesn't seem to allow this.
Same here!
Interesting video, I would be interested in a follow-up video that shows the antennae you used for each of these applications.
Antenna design is something I hadn't given much thought to until I tried SDR for 1090MHz for FlightRadar24 - for the first attempt I connected it to my TV aerial which worked absolutely fine... in a very narrow arc of sky!!! Yes, a highly-directional antenna for an omni-directional application! I then found instructions for a homebrew 8-element colinear antenna on the net, built that and it worked so much better.
There's nothing like a properly tuned antenna for the given frequency that you wish to receive. Coliears are good because they can be quite wideband for the given frequency they are designed for which gives you some margin for error when homebrewing antennas. 1090Mhz is such a tiny wavelength so the antenna doesn't have to be big at all. I can cover antennas in a video as I have built many over the years, but I'll have a think about what content to have. Thanks! :-)
What about drone (dji) communication data. Like whether to go forward or back, up or down, their video link. That kind of stuff? Can it visualize that sort of data?
i know that it is a little topict could a software defined radio be used tn conjunction with an array of broadcast antennas and a small transmitter to map metal detection in a small area providing info that a standard metal detector could not?
I couldn’t answer that 100% as I have no experience with that, but an SDR receiver can receive on a wide range of frequencies, so if you knew the frequency to look for, and recognised what was being picked up, then possibly. Do you have any links or more information on this subject?
my bad the way most metal detectors work is to send a big signal out then quickly switch to using the antenna as a receiver and look for interference with the signal it sent out they use a number of frequencies so while i could find out they will likely be low frequencies it has just struck me that a computer crossed with a metal detector had possibilities sdr modules are half the battle.
How do you feed the audio from the SDR into other applications?
Either the apps support ist directly or through Virtual Audio Cable
Thanks for share , SDR can also analysis MMDVM digital spectrum
DE BI7JTA
Would this unit be usable for scanning truncked 800+ Meg police radio (scanner).?
Thanks for sharing your video.
yes it will.
Great information. We cruise the sea on a sailboat, can this be used for weather info, grib file content over the air - do you know?
I’m not entirely sure about grib files. However, you can most certainly receive weather faxes from orbiting satellites. I’m i the process of creating a new video which may cover this. Thanks for watching :)
Tech Minds There are freewares, UGRIB for ex, but they require a download from the web. It would be special to use this in areas too far from shores. Im rooting for you👍 Ordering the hardware soonest. Thank you for the vids!!
Derek O'Brian Thank you for doing this research. I now have the hardware in hand, next is the time. Hopefully this weekend. I have an ssb isolator in my standing rigging. Going to attempt w small antennae that came with, then connect it to the ssb antennae to the diff, which may be necessary. Will keep you posted soon. Thank you again!!
there exist other videos on youtube on how to recieve recent NOAA satelite data (of different varieties) with an SDR and DIY better arial. like this one: th-cam.com/video/cjClTnZ4Xh4/w-d-xo.html
The software that you show where do you get it from and is that the only software , drivers you need?
Thanks for the video! One question... If i have the SDR with the little antena what can i hear? Thanks!
Well, it depends on what the resonant frequency of the antenna is. Normally, the higher the frequency the small the antenna, unless it's a dish of some kind. But that antenna could be loaded, which means its trapped for other bands. So saying just a small antenna we could not be accurate at which band its meant for. It WILL however, be for anything 50 Mhz and up. Anything below 50/30Mhz normally would entail having a long piece of wire. Best thing to do is plug it in, and see if you can pick up anything around 100 Mhz (for Broadcast radio) then between 144 Mhz and 148 Mhz, then 430 Mhz upto around 440 Mhz. If you find you are not receiving much, invest in a multiband antenna, like a discone: amzn.to/2HMnMty or maybe something like: amzn.to/2GK0g0U However, you can always just try a really long piece of wire hung up over a tree for example which would be perfect for anything below 30 Mhz.. Assuming your SDR can go that low (normally a UpConverter is required) depending on the SDR you have.
So nothing about police radio? Thanks for your response!
Depends where you live for police scanning. In the UK, where I am from, they are encrypted and digital, where as I believe in some states in the USA you can listen in using an SDR. Take a look at www.radioreference.com for information on local tranmissions. Might give you an idea of what frequencies are local to you.
Thanks for your response! I'll buy one.
which antenna type should use for each one? Im new to SDR
I liked that video simply for the summary at the beginning. I wish more TH-camrs would do that.
(Would be even better if you had the timestamp for each bullet points)
What, if any settings are required setting by default listing to the audio from a stereo plugged in speaker buds on a raspberry pi 2B+?
Hi Matt, and how about the dtv channels? Is there any receiver for getting abroad channels?
Its is possible, I have connected my SDR receiver to a Raspberry Pi and used KODI with a PVR plugin. I will do some research on Windows Software too and possibly make a video on it. Thanks!
I want to catch hold of unknown frequency and for that do I need wideband? And if yes then what sort of sdr recvr do I need for that? Or can I get it using some software is the solution please let know the software to download?
How to receive weather satellite pictures?
With the AOR3000a it was possible when adding a printer.
Is it possible to show the weather satellite pictures on a computer using a SDR?
@Mudkip909 thanks
I first need to get it working again
I thought maybe mine was broken and purchased a new one
Unfortunately this one gives same error🙁
@Mudkip909 "device found but in use" in my laptop
And when i thought I try on my Android phone it say 0 device found
Hmmm, I hadn't heard of "DMR" as a modulation type yet, but not nuts about the way it sounds.
It's a Digital type of modulation, much like DSTAR, P25 etc etc etc :-) If you want to listen to more DMR search google for DMR Hoseline, it's a website which streams DMR Ham reflectors in real time.
Hey I hope you read it. Can it receive or sniff 2.4ghz ? like zigbee or nrf240l protocol.
Hi friend.. Thanks for the help last time I have bought at 100Khz-1.7GHz Full Band UV HF RTL.SDR+USB. And ran it through a dsd+ but it all I seem to get is just white noise. Not sure why just wondering if mite know cos am new to all this.. Any info would be very appreciated.. Thanks pete
I have tried using Nooelec SDRs, but the noise level is so high I cannot hear anything. I have an up converter as well and attached all of my Ham band antennas and it is still too noisy. After several weeks, I finally gave up and put them away.
Thanks for sharing your successes with your SDR.
73 - de Mick, WB4LSS
Hi Mick, thanks for the comment and watching my video. It could be possible you have some Local QRM or maybe a faulty SDR. I have a couple of NooElec dongles and the more expensive one is definitely better with regards to sensitivity and noise.
Tech Minds - I have had mine for three or four years and couldn’t tell any difference between the high-end Nooelec and a cheap $8 dongle.
I rarely see peaks above the noise level and those are mostly some sort of digital transmission. I may give it another try some day. Thanks for your reply!
- Mick
Mick Bradford If you plug your TV aerial to the SDR you will likely hear a lot more. I spent weeks with the ANT500 but it was just so weak I gave up. You could also use an android phone or tablet and connect through an OTG cable which will give you the ability to move outside at higher elevation which may help
Play around with the RF gain,and disable the automatic gain control. IME it cranks the gain WAY up,and just raises the noise floor to the moon. I get much better results adjusting it manually.
if your a ham then you can build circuits and stuff, get a hammond aluminium project box, and install the dongle into it, take off the usb plug and hard wire a "proper" screened usb lead to the board, desoldering the antenna socket and soldering on a coax with a bmc plug fitted to the box will help, lastly put clip on ferrite's on both leads as close to the box as you can.
turn off the auto gain(net searches will show you how), and set the gain slider to 3/4 manualy .
this works but only if noise is a problem, most times they work out of the box, it has to be said some dongles are poor(quality control issues), as they cost nothing its best to buy two or three at a time chances are you will get a good one.
this is only for those with noise issues.
What's the automatic scan options on that software?
How do you connect an antenna to the SDR? And since it covers such a wide range of frequencies, wouldn't you need a large array of different types of antennas?
Good question, well, all SDRs have an antenna connection, some even have 2 or more antenna connections. You can buy mulitband antennas, say for 50MHz and below, and then get another type of dual band antenna for VHF and UHF
For this SDR, any antenna with a Micro SMA connector will do (even just a stretch of stripped coax will do!)
A variety of various band antennas _can_ get you the best response, but even the antennas shipped with the kit does great!
"If you are wearing headphones, be careful"
Thank you!!!
X of
+1 for the most important advice here. Especially when you tweak around with the squelch function.
can it be used to scan rf to check proper frequency to set radio mic without any interferences and dropouts?
Well, I have the Ham and digital covered, but I may have to look into SDR for the other options that I had not thought about.
Does it pick up microwave frequencies? I’m experiencing Voice to Skull (V2K).
Thank you for the tip about virtual radar. I have it going now and I love it.
Would u get tracked if you monitered a certain frequency ??
Nope, can’t track for listening
Blood hell that is MOSS voice (Richard Ayoade). "Come here ROSS listen, this is MOSS on youtube!" Big fan here from IT Crowd
I literally got into listening to radios , so this can pickup CBS like trucks,planes,pmr446? Or I have to buy addons ?
Normally CB's are around 27Mhz and planes are around 120mhz, pmr446 is around 446Mhz, so as long as you have the correct antenna for these frequencies then yes, you can most certainly receive them :-)
Tech Minds MHz? So cuz I. Have a uv5r radio I’m just used to uhf and vhf idk what MHz kinda is ? Basically it’s the same right?
Like example pmr446 channel 3 would be 446.000 whatever the end thingy is MHZ ?
I’m new so idk antennas really but like things I really want to listen to is yeah airplanes cb truckers security pmr446 channels and all that
There’s one of these on amazon what comes with 3 antennas but I really don’t know what antennas I’ll need for things I want to listen to I just like listing I ain’t read up on these things lol as I don’t get the antenna my uv5r I just use 1 antenna for all
I’m guessing cb I’ll need a different antenna but vhf And uhf I can use same antenna? Only thing I heard is for cb I need a uh proper setup ? But I kinda want it portable
Here’s the one on amazon comes with 3 antennas or 2 could you tell me if I can pickup things I want?

What antenna are you using in this video?
Are you able to record what you recieve ? FM , etc.
Yep sure can, plus you can record what you see on screen and while playing back you can change frequency within the bandwidth of what you recorded.
@@TechMindsOfficial Thanks for the reply, I was hoping to be able to record FM radio programs for later listening.
Can somebody tell me if this works for listening radio in analog ways? and if works too for searching catching up the signals from a rf remote for example? thanks in advance
I used my SDR dongle to align my DirecTV dish for max signal.
Hi nice article...i have SDR# and then downloaded DSD+ ....but I don't get the DSD+ Interface Menu in the menu of SDR# how do i rectify this?
You need to download the plug in from the link in the video and place the DLL file into the SDR# directory. Alternatively you can use DSD+ from the command line without the sdr# plugin.
Wow...super quick answer...thanks
But which link...sorry?
Andrew Kinch See my other video and look in the description. th-cam.com/video/Je2WUfYY0xI/w-d-xo.html
Hey guys! What happen if I try out my RTL SDR with an wifi antena 802.11n? Can I use this antena for something? Thanks!
This is cool. I remember having to use old moto bravo pagers for POSAG data. This seems so much easier. Thank you
How do you listen in on project 25 frequencies
Great videos. I've always been fascinated by radio and what can be achieved it with modern tech in this regard. One thing, I bought one of the USB receivers and although it works well to pick up commercial FM with the antenna supplied...can you recommend a more powerful indoor antenna at all? Some of us can't mount antennas externally and it'd be great to be able to pick up some air traffic and HAM radio. As it is with this basic kits, you're basically just getting a basic radio and won't be able to listen to most of the things in this video. (correct me if I am wrong, I am still a noob at this!)
Indoor antennas are kinda hit or miss, unless you have access to your loft space. If so, then I would recommend installing antennas in your loft if you cannot access outside.
@@TechMindsOfficial OK thanks for that. Keep up the good work. I've already jumped into the hobby since watching your videos. :)
@@TechMindsOfficial BTW any reason why I couldn't use the TV antenna on the outside roof?
That’s good to know :)
In the UK the 2 Metre (144MHz) band is 144.0 - 146.0MHz not 148.0MHz. There is also a 4 Metre (70MHz) allocation, 70.0 - 70.5MHz.
Absolutely correct! I am a UK based Ham Radio operator but as this video reaches all corners of the globe I wasn't being specific with regards to the frequencies. :-) Thanks for watching!
This video is about listening to radio transmissions, no band restrictions apply. If you are going to transmit, then you need to know your band restrictions and the band plan for your area.
That thing has a very high nose floor. The squelch will help a little... maybe. If the signal you want to hear is high enough above the noise floor. Otherwise it just turns everything down.
hey man thank for the video, do you think that SDR receiver and be used to connect to a laser scanner.
How do you get SDR# to work with a NESDR SMARTee? I've used Zadig to replace the driver, but it doesn't show up as an available device in SDR#.
can you transmit with this sdr? and an amplifier?
Not with this one, you’ll need a LimeSDR, HackRF or an Adalm Pluto
what antennae do you use? I can't pick up any of these signals at all
For this video I am using a Dual Band Co-Linear antenna for 2m and 70cm. Which antenna are you using?
Thank you for the video. I was given an RTL SDR for Christmas and I'm looking at ways to use it, and this video is very useful, I'll have to try out a few of these things.
Good Luck on your youtube quest. I am in the same boat as you. I run a small niche channel that earns enough to pay for itself, but they want to take that all away now. I'm not in it to get rich, but to them that doesn't seem to matter anymore.
You’re very welcome! I’m in the process of creating a Part 2 to this video so keep your eyes peeled for that :)
Can you listen to FM sub carriers?
Please, van you tell me what i sute use for an sdr receiver, i am new top this ,i see a lot of sdr,s on banggood and whis but i don,t know what top buy, regards 🇱🇺
what kind of ariel do you have connected?
I believe I used a long piece of wire for HF and a dual band 2/70 mag mount.
The fact that I’ve just subscribed should tell you what I think of this video!
I purchased one of these and it came with a small antenna. I can barely pick up an FM station. What antenna did you use with your NooElec Mini 2?
Does it work with Linux?
Will it work with Windows XP, that is the newest version of Microsoft OS I've got?
Yep, sure does. Just make sure the SDR software you have is compatible, most of them are. thanks for watching!
Can I listen to emergency in uk? Aka is this able to hack police radio if known how to program by a user? Is it possible.
Also raf bases or milaitry bases.
And lastly PMR?
how do you listen to 6m when it requires almost 5' on each side of the dipole?
That is one of a Masterpiece Explanation
Thank you for your kind words 🙏
I got one of these but couldn't do much with it, I think it was due to the aerial I was using, just the one that came with the Rx. I'd be interested in knowing about better aerials.
