#ATS25 #ShortWaveReceiver #SWL
我喜欢这个电络铁，现在中国出各种各种的收音机，除了一些本土品牌，大都是西方设计的。配上美国的DSP芯片，一切都很容易。
This reminds me ATS-803 (or Siemens RK-651 in DE). Muting click with every tuning step, minimum 1kHz steps and no SSB (BFO only). Using BFO to fine tune SSB signals is terribly wrong idea, because you are not fine tuning, just changing the pitch, so filters does not move, which means that BFO is no more aligned with the edge of the IF filter which in fact means, that you are receiving from both sides of that BFO - LSB and USB at the same time. This may be sufficient for CW usage, where filters are narrow and you can choose whether you tune your BFO under or above the signal and, also, freely choose the pitch, so you can almost freely choose this just to eliminate the interference from nearby (in scope of frequency) station. But this doesn't work in SSB mode, because you cannot choose pitch nor the side, because BFO have to be where the original carrier was. You cannot change this. You can slightly tune this across the filter, but this doesn't help in this case, because you have 1kHz tunning step only. This also implies, that narrower IF filters doesn't make sense. On top of that all, it looks like that receiver has no input filter. There is also no balanced mixer, so I assume there are gilbert cells, which are easy to overload, and it is designed as upconvertor, which requires at least low-pass filter on input. All in all, it has touchscreen, decent Gehäuse, big speaker and battery, really nice tunning knob, but despite that all bells and whistles on it it is nothing more than poorly designed thing, so the result is in my opinion a great no-no! Aneb tady vidím velký špatný…
@@TheMariepi3 Over the Icom 7300 ???
@@FlamethrowersAgainstSnowflakes In the Funcube pro + receiver and in other similar ones based on the MSi001 chip, it is very important that the signal goes into low impedance (otherwise, a lot of signal is lost, in case of going into high impedance, usual in long wires, and it also picks up a lot of noise from the power supply) . The option is to use a short wave ferrite transformer (not just any ferrite but ferrite special for short wave and VHF) in which on the low impedance side there are three or four or five turns (one end to input signal and the other to receiver ground) and the high impedance side, such that with 15 turns, at one end it goes to a long wire and at the other to a metal mass, such as a metal pipe or a metal window. We must take into account the ability to narrow the passband with HDSDR software such that in short wave and other wonders such as automatic frequency control and a good noise eliminator
Niki! Nice analysis!
Except that the ATS-803 was a classic and a fantastic and super-fun radio to use, despite it's shortcomings. The ATS 818 and ATS 818C were great too. I'd take any one of those three over an ATS 25.
Very good overview. As always buyers are won over by things like elegant full colour displays and other gizmos that these designs throw out there as bait. Rather take some time to become familiar with basic good receiver design or speak to a technically astute ham or other RF savvy person before wasting money on what is almost a throwaway design.
Looks good. And, I might add, an excellent overview and explanation- as always. I'm such a gearhead, I'm very tempted to buy this little receiver. Question: Do you think you might install a band pass filter? -Joe
I no more have this radio. I sold it to one my friend.
Fantastic video. I've ordered this receiver as of yesterday. This will be most helpful when I get the unit. Thanks for an award-winning presentation. W2FKN
Thank you so much for your very kind comment! 😊 Hope you will enjoy your new receiver 👍
It's worth exploring in-car installation - even independent of the auto audio-system. A suitable antenna would need to be found; and the display may need to be dimmed - for nighttime driving without a blinding distraction. In any case, it could work well
Don't forget to connect a long wire antenna, when you install it in a car, The longer, the better. 😉
Thanks for this review. Nice receiver but too bad they did not include a spectrum display or waterfall.
They use ESP32 for the display
I don't think is possible to have real time waterfall on that...
А где полноценные диапазонные фильтры? В городе этот приемник без фильтров бесполезен. И никакая, как Вы говорите селективная антенна их не заменит!
Finally good large tuning knob
I’ve been using a Grundy Yacht Boy 400 for 22 years now and am considering buying one of these, just for fun. Seems like a fairly nice radio for the money.
Interesting receiver. I would add two things if the designers are reading this. First, make an variable RF gain control as a menu function and, second, add a fold down bail under the front to tilt the receiver up for easier viewing.

Omoet from bill kd8wtt in michigan,usa verry nice radio good read out i would like one, what is the price. 73 merry xmas bill
Is the am/fm CB channels?
It covers up to 30mhz, and has a switch on the back for FM
Excelente!
Parabéns!

Estou querendo adquirir um rádio receptor que tenha todas as frequências, tipo esse. Qual o melhor modelo de rádio desse tipo?
Ou seja, na sua opinião, qual o melhor de todos?
Está custando quantos dólares, incluindo imposto e frete?
Obrigado.
Can it work for am radio stations also?
Fm music and AM medium wa ve bcst. FM sounds fine.
Жаль что такой красивый приемник с отсутствием селективных цепей по входу остается красивой игрушкой.
All that free space inside..... yet no recieve filters, no spectrum waterfall bandscope, no gain control, no attenuation..... a pretty looking intermod box..... maybe pass it on to a 9 year old when the novelty wares off.... 🤪👍🏼
I'm a Ham Radio Operator and I like it, Nice and small and touch Screen, Like the way it looks.
Thanks For The Video

Nice video. Thanks for sharing. 73 de PU2CLR.
Please take a video on how to flash this radio? Thank you very much! 73!
Good idea! 😉👍
And to add,TY for focusing on the SW SSB part.Most reviews for a multi band radio they spend like 10 minutes on Am-Fm and barely cover the shortwave parts.
Thanks for the great video. I had seen the one like this one with the OLED display, but didn't know there was a color screen available. Nice. Looks like the same architecture as the ATS-20.
Это конструктор??Самому надо собирать??😃🙄🤔
I think this little receiver would work great with a active antenna, Adding a external band pass filter. I Maybe I start making videos again with this receiver and a active antenna. Would make some great content. Putting this receiver through the paces would be lots of fun with a dipole also.
Looks to be a useful portable Rx. Thank's for the video de GW4XDR
Could be a little more compact and rugged. Bet you could put all of that in a handheld unit by changing the speakers, battery and redesigning the pcb.
@@prakharmishra3000 ATS 100
Brilliant review, I appreciate the info as I am new to ham radio. I think its good value for the price and features. :)
In addition to the amateur radio bands, in which frequency band does the receiver operate? Low and high frequencies?
seems to be 100kHz to 30MHz!
So, run a cable to a shielded antenna switch box and then cables to an array of different antennas for the desired frequency ranges you intend to use. Bulky, yes. And unsightly with the different wave antennas on your roof or out of your window. It is an old school fix that will no doubt improve the quality of reception for this little radio.
Hate that chuffing/chugging noise from the tuning. My xhdata 808 has the same chip so same type of noise. My belka dx though is absolutely amazing compared to this.
Yes, fully agree 😃
There is no point in paying more than $ 50 for it.
Yeah. Its like 30 bucks on aliexpress
Looks and sounds great,but that touch screen looks kinda flimsy.I'd rather have plain push buttons,but,then again,with all the features it would have to be a bigger radio then.
I enjoyed this video... I like seeing what components are used and how things work! I have an ATS-20 receiver that I modded with a much larger capacity battery. My biggest complaint is how these radios are called "Full Band Receivers" which they're _not_ at all! Full band means _every_ major band, the two I was looking for the most, 2m and 6m were _missing_ entirely! It could easily be termed a "wide band coverage" radio, but not full band. I'm working on building my own transceiver similar to this idea but using an Arduino Nano, an Si5351 and crystal filters.
Great review brilliant can please ask which would you recommend this one or a xhdata 808
Does it do 0-30 only or cover 2m also 145-147 in UK 🇬🇧 on fm mode??
AFAIK it is VHF broadcast only
@@carlclarke1 understood thanks
Nice little unit, not sure what you connected it to outside but wonder how it would handle a bigger antenna, also curious how well the sync did, it would be cool if one could dial in the tuning step and bandwidth.
The MC-20 Magnetic Loop antenna has been attached. Yes, dialing bandwidth would be useful, pity it doesn't have it, true... 😉
I was so excited to see this Receiver , I went on line and read to many complaints about the Receiver having problems with the screen .
It's $100 tho! Ouch! 🤕 💰
Bought one...it is a great little receiver. There are software updates that are now available nice job
Nice and informative VDO. I own an ATS-20 and it is a good receiver as well. By the way, for the FM mode of ATS-25, can it tuned the FM to frquency step size of 0.05 MHz ? Thanks. de AG6DH
I don't like not being able to see the selected frequency tuned when fine tuning with the BFO, I don't like the 1khz tuning step limit. What hardware limits prevents the tuning steps from being programmed to 1 Hz resolution with the processor firmware? Other than that it is impressive! I like its portability. I just will not purchase one until it can offer more than my current radios.
I think it has 10 or 100 Hz step limit. Push function.
very thorough.. I was wondering about this little unit.. thanks for the tip on bigger antennas.. I may just get this for camping.. I enjoy parusing through the bands at night just to hear others chatting away I find comfort in it as I fall asleep.. Carry on!
Most of the conversations on the ham bands do put people asleep
My ATS25 recently stopped working after getting about a year's worth of use out of it. Turned it on, tapped on the screen and it went completely white not sure why? I have the ATS25X1 as a backup we'll see how long it lasts.
This is an honest and professionally thought through video-documentary. There are countless videos about this product on various media. This is one of the best editions without a question. By the way, the publisher will forgive me and will not think I am condescending: This is one of the few persons with clean manicured fingernails. Call me "old fashioned" but this shows me how a person is perceived and respected. Well done docu and highly recommended!
Receiver 😂😂😂😂
Bluetooth receiver?
Wi-Fİ receiver ?
İt's a radio man!!!!
is it possible and have a full band antenna on it I do not have garden and I want to hear all of the world radio stations via radio signals.
Sincerely👍👍👍
Yes, use multiband vertical antenna like Diamond CP-6 for example.
I just buy the Mini SSB receiver ATS-25 (LW/MW/SW/FM), connect the antena ,a long wire 20meter , and check the receiver : very poor sensibility all the band , just with FM i received 3 stations , i open it and nothing to ajust ..... it is only software .... someone tell me what happened , it is a malfunction receiver i buy it 77 dlls Us
Just got mine. FM super. HF and Bcst AM very poor. Outside by garden with 12 ft wire can barely hear anything on any ham band. A few very weak CW and FT8 on 40 and 20m. Those are booming in 599 on my other radios. Expect i got a dud. Frustrating. But thanks for nice video. At least I know some work. Designers should have put in auto swith filters. A small tuner . Just bcast variable cap and a couple of switched coils will help. Now to get one whose HF/MW reception works.🤨
Thanks a lot for sharing this stuff in the video
I'm glad to see a sensible bnc antenna connector. Why we're still stuck with bulky threaded uhf/259 connectors for hf xmt/rcv is unexplainable.
They are easier to connect by feel. I just connected a CB antenna to the back of my R71E. A BNC I would have to turn the radio around.
Looks good, would like to have one!
It not really an Arduino manufactured MCU, it is an ESP-32. Espressif, the manufacturer of the MCU, provide an Arduino compatibility library. It is a good move MCU-wise as the unit could feature Bluetooth and WiFi someday with new firmware. Thanks for the video, I wanted to see one working.
Yes and is easy to modify or add more features 👍
What a lovely radio and very well presented. What is it like on NDB band please?
Thank you! 😊 Here is explained what is NDB: en.m.wikipedia.org/wiki/Non-directional_beacon
Wish you had tested it with the telescopic antenna attached.Hardly a thorough review in my opinion.False,in fact.
Battery indicator doesnt read the correct voltage. Cheers from old George
Yes, George true. I also forgot to mention that S-meter doesn't indicate correct too.

@@MakeDoAndMend1 Thanks! System is based on Arduino so voltage measurement should be the same like here: linksharing.samsungcloud.com/j2IMOnwoCEia

@@OM0ET Many thanks. I am just getting back into radio. Also tomorrow moving house if all goes well. No funds for a transceiver at present. I have created a Ham radio playlist if you want to watch . Cheers from old George in the UK 🇬🇧🤠
wb2bjw - Hello Paul thanks for doing this video. It looks like this receiver would be good for short wave listening of the bands. What type of battery does it use.
Is there noise while charging and listening?
This would be plugged 24 7 at my desk.
Very attractive looking radio. I saw a slight variant called the ATS-25C which has a ferrite bar for MW and LW. Also there is the never ATS100 SI4732 Radio Receiver which is pocket radio with a colour screen, similar form factor to the Tecsun PL-365 but smaller.
FYI: If you have a digital antenna you will need to get a BNC male adapter to replace the antenna it comes with.
Another one with tunning mute. Not good.
Yes, that's true. I also hate this short muting while tuning.
ATS-25 or SDR-Play RSPdx? Thank you!
If you don't have 00 decimal accuracy how can you tube ssb ?
It has BFO
Any schematic diagram possible for technical study ?
try some speaker wire you can make them into antennas
Most ugly part is the BNC sticking out from the back .
HI Paul I have question about ATS-25 and it's Synchronous detector, is it any good, I have few Tecsun's radios like H501X and must say that all Tecsun's DSP radio have very crapoy Sync AM... Thanks for any info.
Why do you classify your latest vids for adults? I'd need to authorize my age to watch them and I don't want to tell this Google.

I watched all of the ARS-20 and ATS-25+ videos but did not hear one of them that tuned into CW signals to test the signal stability, selectivity, and sensitivity relative to a local antenna. I find no other SDR receiver out there that fits the category over what is also a full-blown transceiver. 72 es 73, Dave - KU9L
Is very difficult to do something with CW when minimal tuning step is 1kHz 😀
This receiver front end is terrible, I could not use it at all in our area because of total AM broadcast band overload. Local AM stations were broad band everywhere and the resulting sequel and noise level made reception of any receive totally impossible with the telescopic antenna or the outside antenna. I had to build (ARRL handbook) and install a BCB filter that suppresses the AM broadcast band by about 40 DB. After this it works great and there is enough sensitivity to hear local AM stations although DX is impossible The filter is in a small aluminum box with a male and female BNC connector. The second item I had to do was changing the encoder as the original encoder skipped terrible. Overall after those changes it works fine.
Is it possible to set a finer step (maybe 10Hz) so you can actually tune in the SSB? 1000Hz is OK for AM but way too much of a step for SSB
It does 10 hertz stepping... 🙄
Push the tuning knob in to toggle 1khz/10hz tuning...
Hi there, can you tell me what kind of antenna setup you were using on the 40M clip. Many thanks.
Soon as I saw the charging port.....I'm out of here!
No Thanks!
BTW the ATS-20 is wobbly loose fitting junk.
I removed dangerous main battery and installed a 3.5mm jack for external power from brick. So much better but lose memory so I installed a button battery to retain memories. Easy to do.

Hi Paul, can the display be shut off to conserve battery?
No there is no such an option in the menu. Hopefully in the next FW upgrades they should add it. 🙂
No spectrum display? My Malahit-DSP SDR has one. The screen appears to be the same size with most buttons many hidden options and id is smaller in depth. Sounds good with headphones.
Nice video but it says in the description LW/MW/SW/FM and I am very interested in the WFM and the maker of this video only shows receiving around 7,2 mhz (but this is always happens when it falls into hands of ham operators making a video). For example:"Can you change bandwidth in WFM"?
Very good, thanks for this nice video!
Compared to some radios I’ve opened up, this one is a rather simple design. The radios of the past ran valves “vacuum tubes in our language “ and they too were somewhat straight foreword in design.. I’m gonna have to check out this particular rig as I’ve been addicted to ssb dx thanks to remote hams.
Good video , easy to understand.

Like a Tecsun pl 660
Good receiver. Such a receiver is useful when there is no way to turn on the transceiver to listen to the ranges. Good luck - Удачи! 73! RT9TM
I made a hand-made reciever on SI4731 chip. It has a bad senesitivity on AM band (too big noise) but in FM band all is OK.

Thanks for your support and watching my videos! 😉👍
Is it possible to upgrade the firmware in this radio?
Why would you?
Arduino libraries are used in this radio, so I guess it shouldn't be the problem.
@@egbertgroot2737 It's one of the reasons I'm looking into these radios. I've seen other ATS-25's with Arduinos in them that you could easily connect to with a USB cable to update the firmware for fixes, improvements, and additional features. I couldn't see a USB connection on the ESP32 board behind the screen on this model,\ where I do see the USB connector on the ESP32 boards you can buy by themselves. So, that's really why I asked. The board in this model might not have a USB connector making it more difficult to connect and update the firmware. It could have the connector routed through the USB that goes out the back, but I don't know and it looks like that USB port is just for recharging the radio. So... I had hoped OM0ET might know more about this....
@@egbertgroot2737why wouldn't you?
it's simple, to fixed software issues and bugs, or make improvements to the software.
Like the latest firmware makes the soft muting and chuffing when you turn the frequency a lot less of an issue, improvements of the overall capability of the radio and so on.
Hi great video I have the ATS 25X2. Where did you get your cool antenna?
Thank you! 😊 I produce and sell this Magloop Antennas www.om0et.com
Interesting little receiver.
Just received my radio from eBay today. When I turn my tuner knob to the right, the channels go "down" instead of up....can the wire harness to the decoder (tuner) be flipped over to fix this?
and the ats-100 has similar characteristics?
