Only temporarily sold out. Hundreds more available in a week or two. Also soon from distributors. So popular we can't build them fast enough! Overpriced? I hear this from people who don't understand the standalone architecture. With other SDRs you need to be amortizing in the cost of the attached computer. And the cost of your time in installing software. The Kiwi is designed to solve these problems in an easier way. I invite people to learn and discuss on the Kiwi forum. Thanks for the review Matt.
Congratulations on an excellent product. There are an amazing number of these from around the world accessible online (using the link provided). There couldn't be a better way to demonstrate how good it is.
@ThePrivateMan3301 Well now you have to differentiate between computer on the server-side (Kiwi) versus computer on the client-side (user/browser). For the vast majority of SDRs that generate IQ streams the server/client is effectively merged into one application on the computer. And they are single-user (some are now starting to develop server solutions). With the Kiwi you get an integrated server able to handle multiple user connections simultaneously (that can tune the entire 10k - 30M spectrum independently). Many Kiwis are placed in isolated locations due to noise issues. And some find it easier just to deploy a Kiwi versus an IQ SDR plus computer, software and some sort of screen-sharing setup with the computer (assuming there isn't a server solution for the IQ SDR). And then what do you do about multi-user if that's a requirement?
I'm a HAM operator and bought a KiwiSDR 1 two years ago. What shall I say? I was the best investment ever! It's not just listening to some radio stations. It's like diving easily deep into the universe of Long-, Medium- and Shortwave. Reception is excellent with a decent outdoor antenna, for example longwire, dipole or magnetic loop. Much more fun than I ever thought. And you can share the fun with others - it's simple to open your receiver for the public if you want to. I recently bought the KiwiSDR 2 as a backup. Good idea! Best wishes Michael, DO6LSM
I own two of the original model. I have over 60 years of radio experience including broadcast transmitter maintenance. The hardware and software of the Kiwi are head and shoulders above anything on the market. I will probably pick up one or two of the new model in the near future.
I just spent the better part of the day exploring what the KiwiSDR can do. Amazing. Insane. A complete deep dive into radio on a worldwide scale. Cost for entry pales in comparison to the R&D that went into this product, and service. Kudos. I went from on the fence to where can I buy.
You're perfectly right : I received it 5 days ago, and I'm on it most of the time. It's a very cool receiver, I have an openwebrx with a rapsberry pi / sdrplay too, but this one is so easy to use...
I use Openwebrx+ with a RSPdx. just wondered if you have any issues with bandwidth changes between profiles and the waterfall sometimes going really slow. I suspect this is due to sample rate changes and the switch between different antenna inputs
@@BillyNoMates1974 correct, these are issues that the KiwiSDR does not have. I had the first version of KiwiSDR until I fried it and then it was no longer available. Tried OpenWebRX+ with an RSP duo, but does not even come close, as changing bands changes the band for everyone on the SDR
Love the idea of a system that can be accessed remotely, not just by others around the world, but my the owner. Also love the idea of integrated software. Right now everything out there is a patch, FLRig, etc. soundcards, boxes.
€372, excluding taxes, import charges, and shipping cost. Which means that for someone in Greece (like me) to order it, the final cost will be almost €600, with 24% VAT, import charges, shipping, and the custom clearance charge DHL imposes, that can be €60-100. I think they should better find some local distributors in Europe...
@@SotosH65 Not sure if their production and the market are both voluminous enough to add extra profit margins for local distributors. Your calculation of all extra cost seems pessimistic to me. It looks like a great and fun thing to have, light weight, not a huge parcel to ship and I'd be happy to find out what it costs to get it here. Down under people are used to the fact that importing from far away can cost some money. We will get used to the idea too ;-)
Wow thank you so much for this video ive got a few SDR's including an RTL-SDR, HF-Discovery Plus, Nooelec, SDRPlay RSPduo & so on the list goes BUT all of these require you to pipe the audio out to other software, one of the many advantages of the KiWi SDR is that it does it all for you in o e box. Regards Wayne VK3ECS. ive always wanted a KiWi SDR .
When you said VLF to HF l was thinking ….bet they didn’t add a gas discharge tube for lightning static… nice to be proven wrong, confident that it has been designed correctly.
Another excellent video. I access other people's KiwiSDR stations often and would like to have my own to share. However, I'm very limited in antenna space and my densely populated neighborhood is very noisy (radio-wise). My reception service would not be very good. BTW, it's worth mentioning that in addition to the great decoding options in KiwiSDR, it's possible to connect to other decoding software using virtual cable (VB Cable).
I am curious as to the channel selectivity on lw. I was using a public Kiwi in Illinois with great lw noise floor, and was logging NDB cw calls. I noticed the selectivity was not very good in that range, as the calls heard were covering many of the adjacent slots without sharp selectivity being apparent. Many slots in fact. Do you know if the Kiwi design characteristics are massively different on the lw range as compared to the predominate hf ranges? Selectivity being the main concern? Thanks!
A: You must zoom far in enough so you can adjust the edges of the green passband symbol to get the precise selectivity you need. LW selectivity is exactly the same as for HF.
Since you seem to be on top of the latest and greatest SDR hardware… do you have any info on Analog Devices Jupiter SDR? I have an article that states it was unveiled the end of march in Orlando, Fl. And there’s a bit in ADIs wiki about it but that’s all I can find.
I've just read in Twitter it's soon to be available by around 1000 Euros. For a dual receiver/dual transmitter with lots of ports, 2GB RAM seems a very competitive price. However, for my preferred application - DX reception between 0 to 108MHz - , I was a bit underwhelmed by the ADC used: though it covers from 50MHz to 6GHz, delivers up to 40MHz of IQ spectrum, its bit depth is only 10 bit. Well... the world is now owned by very wide signals UHF and above, so the specs make sense... for LF, MF, HF and FM DXing, I don't think we'll see the Jupiter being used a lot.

so whats the beef with KiwiSDR and Openwebrx ? They look very similar like they were developed at the same time or even the same thing they has diverged over time
@@hg-sx5nk KiwiSDR webif is a OpenWebRX clone which has since then been advanced and new features added. then a quarrel began between the builder of OpenWebRX and KiwiSDR, which was solved and then later on came OpenWebRX+ but it does not (yet) have all the features KiwiSDR has
A new SUB here :) - I love the video/content/delivery! - I'd love to enter this world :) - Any recommendations for online education for HAM radio/antennas/etc? Thank you!
I don't have any problem spending $395 for this wonderful radio, but not over $530 with shipping and tax from a European vendor. Please let us know when this item will be stocked at an American outlet. For now, I'll just listen and tap into everyone elses receiver.
ET ships aka UFOs seem to be standing wave EM energized on the hull, the small 10-15m scout craft likely have a main tone around 10MHz and complex harmonics up and down, all the way down to audio range and at least up to GHz. GHz might even be a dominant component. Try looking for it. Sightings suggest at least 200 sorties around the world every day and they might put out considerable power levels so should be detectable from 1000km+. Larger craft will have deeper tone presumably. It will be a strong signal that has no data. When close they sometimes emit a sound like an agitated bell, a bit like meditation vessels. Similar sound might be recognizable in RF as a beat frequency or something. No FM modulation of course since it's a side effect of the propulsion. It is a certainty that ET ships frequent our skies and there is strong evidence of EM and RF, only a question of how easy are they to detect. Coastal areas might be the most frequent as the regulars seem to have bases on earth, specifically in the continental shelf sea floor.
I don't think it's "needed" as such, it's more of an option. Best place to ask would be the KiwiSDR forums as there will be folks there that know alot more. Cheers
Ok I'm not shore this question is sensible, but what is the point of ypthe clock imput? I would have thought that with both gos and ntp you woulld have plenty of clock sources
It’s so you can use your own Reference. NTP could not be used in that way, and perhaps you might want to install at a location you cannot get a GPS signal.
I have an Airspy HF+ Discovery for VLF, HF and VHF, and an RTL-SDR for higher frequencies, accessible anywhere in the world via OpenWebRx+. Can anyone tell me how the KiwiSDR 2 is better? Serious question.
It's not about being better/worse; it's all about features much alike comparing a Mercedez-Benz sedan to a 8-passenger mini-van. KiwiSDR allows 4 simultaneous users that can tune any frequency between 0 to 30MHz all times; plenty of decoders for digital modes out-of-the-box; it's self-contained solution, just plug antennas, LAN cable and forget it. To offer the similar featureset with HF+, you would need 4 dongles, dozens of hours setting up the decoders and a computer to act as a server.
Hi Matt why is it that the kiwi SDR has sold out? Although the timing of your video is only about three hours old by the time I watch it? It seems to happen on a lot of products even from some of the other TH-camrs that I see I know the products that you get aren’t sponsored, but even when I’ve seen sponsored as they seem to have been sold out, so we can’t buy them anyway
They will have 100's in stock soon, according to their replies on other comments on this video. I know nothing of their stock levels, I simply ordered one, received it, and made a video on it. :-) Thanks for watching.
The device went out of stock before they could stock the shop ;) There was an announcement on the list that v2 would come out and everyone ordered it once the announcement went out. New ones are being build and shipped as we speak
Why is 14bit automatically high dynamic range? It's a finer resolution of the dynamic range in the first place but isn't higher. It would be more interesting so know what the receiver noise is and the sensitivity instead the bit resolution in my eyes.
@@TechMindsOfficial you said in the beginning it has 14bit which provides a good dynamic range. That intends that the higher the bit resolution the higher the dynamic range, isn't it? Maybe english isn't good enough....
@@TechMindsOfficial Ah ok. 😄 Maybe a basic knowledge video about snr, dynamic range, sensitivity, saturation and resolution of a receiver would be an interesting topic for a video. It's almost the same with CCD sensors of a camera.
@TechMindsOfficial When you mention your EFHW, I have not heard to mention for which band, at least in the videos I have watched. Which band is the antenna?
I'm sure I read somewhere in the documentation about SSH. Remember that you can just buy the "cape board" on it's own, where you have to supply your own beagle bone and install the software, so I am sure you could have SSH access if you need to.
A: Yes, since the interface is browser-based it runs on almost anything, including Linux-based devices (but devices with small screens are not so good). The Kiwi's application processor itself runs Debian 11 Linux.
@@hg-sx5nk Thanks. They are great boxes but a pity there isn't a single operator low latency mode for transceive use. I guessing the multiple slices slow it down even if you don't want them. Makes tuning very spongy. Should do well nonetheless. Built-in proxy is good news for CGNAT sites.
Imthinking To build an sdr with around 5 antennas that youwill need to put in coordinated position onm your car roof or in camping ground, then you will be able to see where the signal is comming from and right now the thing works, but there are a lott of buggs , im notthe one who is designing and making it, but my friends are, it will change so much things, it will show you detailed location from where the signal comes, best to be used on car roof because all the m,ovementt gives much more detail, but if you aint moving the target may and tthats the trick.
Excellent ! Question from a user: if I listen via PC everything works fine. If I go to the link with my Android smartphone this appears: Unable to reach the site. Why? Other.. KIWI sdr app is not available for my device Thanks
This is a solid product projected almost 10 years ago with absolutely no competition up to this moment in terms of features and price range. KiwiSDR2 is actually a monumental effort from the author to produce a new batch of these receivers. Its key components experimented with huge price and availability issues following the electronics industry supply chain quake due COVID-19. Including a new power option, potentially a very noisy one, would require hundreds of hours of testing and circuit revision.
I really like where SDR development is going, but my feelings are mixed. Once I plug in my radio to an ethernet cable, I feel in some ways the magic of radio is lost. Does anybody else feel this way? I love going onto the Kiwi site and remotely using other people's SDRs, but something about being connected to the internet bugs me. Where does the magic of looking for open windows of propagation end and the relative mess of the internet begin? I feel like somehow my skills as a radio amateur become diminished. Now, this SDR from Kiwi doesn't transmit, or will it eventually? Lots to think about.
technically with SDRconnect, you could have one pc as a server and a client pc with SDRconnect configured to work over network and get a similar result. you just cant decode different modes or currently add your own memory bandwidths
Completely two different products catering for different solutions. That's like saying I'll stick to my push bike instead of my car. But SDRPlay devices are also one of my favorite SDRs, especially the RSPdx. However, it's a different product all together. KiwiSDR is designed for quick and easy deployment of an SDR receiver that can be reached from around the world over the internet, straight out of the box. Cheers
On kiwi forum I ask if root should be running the kiwi service, maybe just a mistake. Explained why its not good. Today my account is read only, and the post was removed. That is not cool. Now I am seeing the real side. Another thing that bothered me when I ordered mine in early March. They charged me right away. But did not ship until April 2nd. I sent an email asking why I was charge already. The response was not in email. But on the forums they changed a subject that had been closed. Saying that cards are charged because this is only the 2nd run. You guys are buy stock before its built. So if you dont like it, let us know and we cancel and refund your order. I sure someone else would love the sdr. Not very kind customer service.
I cant comment on the forum issue you have, but with regards to paying 100% for something before its built and shipped is not a problem for me, and people that want to be on the list for a relatively limited supply of a product. I have done this many times in the past, just so that I ensure I get the product I want. KiwiSDR is huge in the world of online SDR, extremely sought after, so I guess they need to make sure the buyer is a serious buyer. It also helps them get a feel of the current market requirement. IMO of course..
You are doing a great job! Can you help me with something unrelated? I have a SafePal wallet with TRC20 USDT in it and I have my recovery phrase: [pride pole obtain together second when future mask review nature potato bulb]. How do I transfer them to Binance?
Wait, what? This unit is £320 and covers 10KHz - 30 MHz. But there's a USB module that covers 10 KHz to 1.7 GHz for US$40.00 (RTL-SDR). Weighs less, costs less, does much more. What's going on? Have people lost their minds?
KiwiSDR is a self-contained solution. You plug in your network, turn it on and you have an SDR that immediately serves up to 4 users simultaneously tuning anywhere between 0 and 30MHz and has every digital decoder of the most used modes on MF and HF. The USB module you have would need at least a PC, dozens of hours to setup the same decoders and can only support one user limited to the 2MHz slice selected at the time.
@@hg-sx5nk Yes, and four RTL-SDR units cost US$160 and cover a much wider frequency range. I say this only for the sake of comparison -- most users would want one receiver connected to one antenna for US$40. This just makes ... no sense at all.
@lutusp Even though the RTL-SDR are absolutely great SDR, they have NO comparison to the performance of this SDR at the frequencies that this covers. Everything is designed for a reason, the KiwiSDR 2 has a specific reason. Cheers
@@TechMindsOfficial > "... they have NO comparison to the performance of this SDR at the frequencies that this covers." Now *that* would be a great video (hint, hint). I say this because the RTL-SDR unit works extraordinarily well. From a scientific perspective, the unit you're describing would need to demonstrate a level of performance that, apart from merely improving on the RTL-STR, would need to do so consistent with costing over seven times as much. But what do we know? No one has made an objective comparison. All I can say is, it would be a tough test to pass. It would be like comparing a Falcon 9 to a Delta IV rocket. The Delta IV does the same thing but costs five times as much money to launch. But, notwithstanding the economics, ULA (which operates the Delta IV) is still in business. When people hear this comparison, they say, "Wait, what? How is that possible?" It's the same here. People don't always make rational choices. Nothing personal, just asking how this is even possible.
Wimp are having a laugh there is no chance that I would ever pre-order from that company not at the price they’re charging for the kiwi STR £490 you might as well say £500 there having a laugh I’d rather wait until it’s properly in stock. Something needs to be having words with that company Martin Lynch and Sons isn’t that bad actually although I think it should be below £400 definitely.
Cons- Not safe to put on the internet. Kiwi runs as root. Cheap gps included. 10/100 network card 4g sd card For $400 I expected more. Pros It is a cool sdr.
An FPGA, a very good 32MHZ ADC, a Linux SBC, support for 4 simultaneous users, dozens of digital decoders, all in a plug-and-forget solution... ....and no other similar product on the landscape for the hobbyist. Perhaps USD400 is too low for other companies to engage in competition!
@@Mr_ASIC Sure. But in our case a consequence of bootstrapping production from scratch. And not wanting to borrow money from the evil banks. So have to set build sizes that are certain to sell well to raise the money to pay the manufacturer. Every penny in profit we've made has gone back into producing larger build sizes. Eventually we hope units will begin accumulating as stock-on-hand instead of selling out every time. I recommend everyone run a small business sometime during their life. A real eye opener..
I was really excited when I heard about this. Web interface blows it for me. No sale. Have any idea how many brick devices I have that wont work with any other browser that Ie5.***. Nah I'll pass especially for the price. Make it so it works seamless with sdr++ or play maybe but I'll pass.
You can run this from any device that has a browser. Laptop, tablet, or phone. Also, from anywhere in the world. It's also upgradable. Maybe I don't understand your comment about bricked devices. I run the original KiwiSDR with no issues. I also have HackRF, SDRPlay, RTLSDR, etc, If I want to access my kiwi from anywhere, I have my phone so I can listen while mobile also. Can you monitor all 30Mhz of HF waterfall at once on any other SDR? The KiwiSDR can ! Yes, it's expensive, I agree with that comment.
Only temporarily sold out. Hundreds more available in a week or two. Also soon from distributors. So popular we can't build them fast enough!

They look very similar like they were developed at the same time or even the same thing they has diverged over time
The original author of OpenWebRX finished his graduating studies and left the code to anyone use, IIRC.
@@hg-sx5nk KiwiSDR webif is a OpenWebRX clone which has since then been advanced and new features added.
then a quarrel began between the builder of OpenWebRX and KiwiSDR, which was solved and then later on came OpenWebRX+ but it does not (yet) have all the features KiwiSDR has
A new SUB here :)
- I love the video/content/delivery!
- I'd love to enter this world :)
- Any recommendations for online education for HAM radio/antennas/etc?
Thank you!
I don't have any problem spending $395 for this wonderful radio, but not over $530 with shipping and tax from a European vendor. Please let us know when this item will be stocked at an American outlet. For now, I'll just listen and tap into everyone elses receiver.
ET ships aka UFOs seem to be standing wave EM energized on the hull, the small 10-15m scout craft likely have a main tone around 10MHz and complex harmonics up and down, all the way down to audio range and at least up to GHz. GHz might even be a dominant component. Try looking for it. Sightings suggest at least 200 sorties around the world every day and they might put out considerable power levels so should be detectable from 1000km+. Larger craft will have deeper tone presumably. It will be a strong signal that has no data. When close they sometimes emit a sound like an agitated bell, a bit like meditation vessels. Similar sound might be recognizable in RF as a beat frequency or something. No FM modulation of course since it's a side effect of the propulsion.
It is a certainty that ET ships frequent our skies and there is strong evidence of EM and RF, only a question of how easy are they to detect. Coastal areas might be the most frequent as the regulars seem to have bases on earth, specifically in the continental shelf sea floor.
What external clock frequency is needed?
I don't think it's "needed" as such, it's more of an option. Best place to ask would be the KiwiSDR forums as there will be folks there that know alot more. Cheers
Can you change the location on the map to approximate location?
Yup, just enter your co-ordinates slightly off from where you are etc.
Ok I'm not shore this question is sensible, but what is the point of ypthe clock imput? I would have thought that with both gos and ntp you woulld have plenty of clock sources
It’s so you can use your own Reference. NTP could not be used in that way, and perhaps you might want to install at a location you cannot get a GPS signal.
@@TechMindsOfficial right shy do I always forget edge cases, my bad :?
Very interesting, thanks for video.
My pleasure!
Purchased mine 2 days ago, £365, along with £75 import duty.
Martin lynch will be stocking them soon if not already.
@@TechMindsOfficial already listed as in stock on lynches
I have an Airspy HF+ Discovery for VLF, HF and VHF, and an RTL-SDR for higher frequencies, accessible anywhere in the world via OpenWebRx+. Can anyone tell me how the KiwiSDR 2 is better? Serious question.
It's not about being better/worse; it's all about features much alike comparing a Mercedez-Benz sedan to a 8-passenger mini-van. KiwiSDR allows 4 simultaneous users that can tune any frequency between 0 to 30MHz all times; plenty of decoders for digital modes out-of-the-box; it's self-contained solution, just plug antennas, LAN cable and forget it. To offer the similar featureset with HF+, you would need 4 dongles, dozens of hours setting up the decoders and a computer to act as a server.
It’s standalone and can be easily shared
Hi Matt why is it that the kiwi SDR has sold out? Although the timing of your video is only about three hours old by the time I watch it? It seems to happen on a lot of products even from some of the other TH-camrs that I see I know the products that you get aren’t sponsored, but even when I’ve seen sponsored as they seem to have been sold out, so we can’t buy them anyway
They will have 100's in stock soon, according to their replies on other comments on this video. I know nothing of their stock levels, I simply ordered one, received it, and made a video on it. :-) Thanks for watching.
The device went out of stock before they could stock the shop ;)
There was an announcement on the list that v2 would come out and everyone ordered it once the announcement went out. New ones are being build and shipped as we speak
Why is 14bit automatically high dynamic range?
It's a finer resolution of the dynamic range in the first place but isn't higher.
It would be more interesting so know what the receiver noise is and the sensitivity instead the bit resolution in my eyes.
Who said its high dynamic range?
@@TechMindsOfficial you said in the beginning it has 14bit which provides a good dynamic range.
That intends that the higher the bit resolution the higher the dynamic range, isn't it?
Maybe english isn't good enough....
Ahhh yes, it's just my wording. Which is why I did not say higher, I said good dynamic range, maybe resolution would of been a better wording. Thanks
@@TechMindsOfficial Ah ok. 😄
Maybe a basic knowledge video about snr, dynamic range, sensitivity, saturation and resolution of a receiver would be an interesting topic for a video. It's almost the same with CCD sensors of a camera.
@TechMindsOfficial When you mention your EFHW, I have not heard to mention for which band, at least in the videos I have watched. Which band is the antenna?
80m through to 10m.... I have a video on this antenna but its at my last QTH, but the same antenna. th-cam.com/video/RsgdcHeP6S0/w-d-xo.html
@@TechMindsOfficial 80 through 10 for TX, all bands on RX ;)
hmm, the price is right, but i wonder,,, is the kiwi tweakable over SSH ?
I'm sure I read somewhere in the documentation about SSH. Remember that you can just buy the "cape board" on it's own, where you have to supply your own beagle bone and install the software, so I am sure you could have SSH access if you need to.
@@TechMindsOfficial meh,,to much trouble, i wait till its available in europe, hmm, it will be more as on the kiwisite (import tax, and that),
Will be available from hamradio.com when they get stock.
@@TechMindsOfficial 498 euro in europe,, auch....
Where can I buy it in US ?
Very cool - K7ABJ
Mummy I want one. But when will they be back?
Works this with Linux also?
A: Yes, since the interface is browser-based it runs on almost anything, including Linux-based devices (but devices with small screens are not so good). The Kiwi's application processor itself runs Debian 11 Linux.
It Looks Like Typical WEBSDR, But Your Own. :D
Oh man you keep costing me money...... :-) oh sold out mmm >I like the plus edition better built in decoders
You and me both!
Latency - does anyone have a view on this compared to the MK 1?
KiwiSDR2 is exactly the same specs and software of KiwiSDR, with only a few changes on the antenna input connection and GPS antenna input.
@@hg-sx5nk Thanks. They are great boxes but a pity there isn't a single operator low latency mode for transceive use. I guessing the multiple slices slow it down even if you don't want them. Makes tuning very spongy. Should do well nonetheless. Built-in proxy is good news for CGNAT sites.
Imthinking To build an sdr with around 5 antennas that youwill need to put in coordinated position onm your car roof or in camping ground, then you will be able to see where the signal is comming from and right now the thing works, but there are a lott of buggs , im notthe one who is designing and making it, but my friends are, it will change so much things, it will show you detailed location from where the signal comes, best to be used on car roof because all the m,ovementt gives much more detail, but if you aint moving the target may and tthats the trick.
I'm new to radio sdr . Would your friend be similar to kraken sdr ?
Please in sosnich
In Spanis
Excellent ! Question from a user: if I listen via PC everything works fine. If I go to the link with my Android smartphone this appears: Unable to reach the site.
Why?
Other.. KIWI sdr app is not available for my device
Thanks
Why is it called a BeagleBoard?
Why not just making this PoE capable? With USB only providing power input you could abandon that port completely….
This is a solid product projected almost 10 years ago with absolutely no competition up to this moment in terms of features and price range.
KiwiSDR2 is actually a monumental effort from the author to produce a new batch of these receivers. Its key components experimented with huge price and availability issues following the electronics industry supply chain quake due COVID-19.
Including a new power option, potentially a very noisy one, would require hundreds of hours of testing and circuit revision.
The price puts it out of reach of most people, what is a pity as it seems to be a good product. 😢
I really like where SDR development is going, but my feelings are mixed. Once I plug in my radio to an ethernet cable, I feel in some ways the magic of radio is lost. Does anybody else feel this way? I love going onto the Kiwi site and remotely using other people's SDRs, but something about being connected to the internet bugs me. Where does the magic of looking for open windows of propagation end and the relative mess of the internet begin? I feel like somehow my skills as a radio amateur become diminished. Now, this SDR from Kiwi doesn't transmit, or will it eventually? Lots to think about.
The internet connects you to the device.........you still have to hunt for the signals.
Nothing has changed.
i'll stick to my sdrplay
technically with SDRconnect, you could have one pc as a server and a client pc with SDRconnect configured to work over network and get a similar result.
you just cant decode different modes or currently add your own memory bandwidths
Completely two different products catering for different solutions. That's like saying I'll stick to my push bike instead of my car. But SDRPlay devices are also one of my favorite SDRs, especially the RSPdx. However, it's a different product all together. KiwiSDR is designed for quick and easy deployment of an SDR receiver that can be reached from around the world over the internet, straight out of the box. Cheers
On kiwi forum I ask if root should be running the kiwi service, maybe just a mistake. Explained why its not good. Today my account is read only, and the post was removed. That is not cool. Now I am seeing the real side.
Another thing that bothered me when I ordered mine in early March. They charged me right away. But did not ship until April 2nd.
I sent an email asking why I was charge already. The response was not in email. But on the forums they changed a subject that had been closed.
Saying that cards are charged because this is only the 2nd run. You guys are buy stock before its built. So if you dont like it, let us know and we cancel and refund your order. I sure someone else would love the sdr.
Not very kind customer service.
I cant comment on the forum issue you have, but with regards to paying 100% for something before its built and shipped is not a problem for me, and people that want to be on the list for a relatively limited supply of a product. I have done this many times in the past, just so that I ensure I get the product I want. KiwiSDR is huge in the world of online SDR, extremely sought after, so I guess they need to make sure the buyer is a serious buyer. It also helps them get a feel of the current market requirement. IMO of course..
@@TechMindsOfficial That is a fair statement.
I guess just knowing that was going to happen would be ok, but I was not aware.
@@RangerUT I thought it was pretty clear that I was paying up front before the first batch of V2 was built.
How much? Far to expensive
Then you won't be getting one.
You are doing a great job! Can you help me with something unrelated? I have a SafePal wallet with TRC20 USDT in it and I have my recovery phrase: [pride pole obtain together second when future mask review nature potato bulb]. How do I transfer them to Binance?
It already out of stock.
Wait, what? This unit is £320 and covers 10KHz - 30 MHz. But there's a USB module that covers 10 KHz to 1.7 GHz for US$40.00 (RTL-SDR). Weighs less, costs less, does much more. What's going on? Have people lost their minds?
KiwiSDR is a self-contained solution. You plug in your network, turn it on and you have an SDR that immediately serves up to 4 users simultaneously tuning anywhere between 0 and 30MHz and has every digital decoder of the most used modes on MF and HF.
The USB module you have would need at least a PC, dozens of hours to setup the same decoders and can only support one user limited to the 2MHz slice selected at the time.
@@hg-sx5nk Yes, and four RTL-SDR units cost US$160 and cover a much wider frequency range. I say this only for the sake of comparison -- most users would want one receiver connected to one antenna for US$40.
This just makes ... no sense at all.
@lutusp Even though the RTL-SDR are absolutely great SDR, they have NO comparison to the performance of this SDR at the frequencies that this covers. Everything is designed for a reason, the KiwiSDR 2 has a specific reason. Cheers
@@TechMindsOfficial > "... they have NO comparison to the performance of this SDR at the frequencies that this covers."
Now *that* would be a great video (hint, hint). I say this because the RTL-SDR unit works extraordinarily well. From a scientific perspective, the unit you're describing would need to demonstrate a level of performance that, apart from merely improving on the RTL-STR, would need to do so consistent with costing over seven times as much.
But what do we know? No one has made an objective comparison. All I can say is, it would be a tough test to pass. It would be like comparing a Falcon 9 to a Delta IV rocket. The Delta IV does the same thing but costs five times as much money to launch. But, notwithstanding the economics, ULA (which operates the Delta IV) is still in business.
When people hear this comparison, they say, "Wait, what? How is that possible?" It's the same here. People don't always make rational choices.
Nothing personal, just asking how this is even possible.
Wimp are having a laugh there is no chance that I would ever pre-order from that company not at the price they’re charging for the kiwi STR £490 you might as well say £500 there having a laugh I’d rather wait until it’s properly in stock. Something needs to be having words with that company Martin Lynch and Sons isn’t that bad actually although I think it should be below £400 definitely.
Cons-
Not safe to put on the internet. Kiwi runs as root.
Cheap gps included.
10/100 network card
4g sd card
For $400 I expected more.
Pros
It is a cool sdr.
An FPGA, a very good 32MHZ ADC, a Linux SBC, support for 4 simultaneous users, dozens of digital decoders, all in a plug-and-forget solution...
....and no other similar product on the landscape for the hobbyist. Perhaps USD400 is too low for other companies to engage in competition!
Anything “on the Internet” should be isolated in a DMZ…
Now my short replies are being removed. I have answers to all your questions. But I'm being censored. Please email or post on forum. Thank you.
Nothing held for review and I certainly didn't remove any comments. Most likely YT doing stupid things. I have no idea why this happens
My comment also vanished
That sdr was over priced in my opinion and sold out too😮.
sold out is markting stratagy 😈
@@Mr_ASIC Sure. But in our case a consequence of bootstrapping production from scratch. And not wanting to borrow money from the evil banks. So have to set build sizes that are certain to sell well to raise the money to pay the manufacturer. Every penny in profit we've made has gone back into producing larger build sizes. Eventually we hope units will begin accumulating as stock-on-hand instead of selling out every time.
I recommend everyone run a small business sometime during their life. A real eye opener..
@@Mr_ASICHave you thought perhaps it's just a great product, with no competition, made by an individual (not a large company like Icom or Sangean)?
@@Mr_ASIC except it's not. They can't produce them fast enough to keep up with demands
in what way is it overpriced? It includes the BB green and the SDR is completely custom made and in a metallic case.
I was really excited when I heard about this. Web interface blows it for me. No sale. Have any idea how many brick devices I have that wont work with any other browser that Ie5.***. Nah I'll pass especially for the price. Make it so it works seamless with sdr++ or play maybe but I'll pass.
You can run this from any device that has a browser. Laptop, tablet, or phone. Also, from anywhere in the world. It's also upgradable. Maybe I don't understand your comment about bricked devices. I run the original KiwiSDR with no issues. I also have HackRF, SDRPlay, RTLSDR, etc, If I want to access my kiwi from anywhere, I have my phone so I can listen while mobile also. Can you monitor all 30Mhz of HF waterfall at once on any other SDR?
The KiwiSDR can ! Yes, it's expensive, I agree with that comment.
