#ATS25 #ShortWaveReceiver #SWL
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.
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.
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. 😉
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.
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
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.
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! 🤕 💰
Finally good large tuning knob
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 👍
Bought one...it is a great little receiver. There are software updates that are now available nice job
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.
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
An update to my last post on this particular site. I received my ATS-25 about 6 days ago. It is nothing like this video since it is version 3.1 dated 27-7-2021 (63). The screen presentations are NOT quite the same as what has been shown here. Much greater screen appearance and not all of the buttons are the same. Clarity is superior, buttons are brilliant blue with yellow lettering. When pressed with the stylus they turn bright gold until fully activated. Menu inclusions are different inside as well. performance is really great especially the FM reception. I tried my discone antenna in the attic and reception was phenomenal on the radio. Of course, there is NO operations manual, directions, etc. This version is a bit tricky to use with respect to moving to another screen, etc. Very happy. Obviously the video here does not completely dovetail with my radio, but is still brilliantly done. Kudos to Paul - OM0ET. I love this radio and paid $127.95 including everything. Took about 1 1/2 months from order to arrival. W2FKN
It was the pleasure to read your comment Rich :) Big pleasure! Thank you and enjoy your new receiver! Best 73 from Slovakia :)
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.
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!
Especially, the big turning dial looks like very nice.
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.
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 👍
Great review - thank you! I recommend viewers hit the playback speed at 1.5x for a good pace.
Great tip
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.
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

Mine sat on a boat for 2 months but it came yesterday and it's more than what I thought , is better than what I thought . I like it I love it , but I use a long wire. Mother nature is kind right now but this thing even has a little display on FM that tells what's playing and some of the lyrics or whatever the radio station wants you to know but they fixed the voltmeter on it too so I must have an upgraded model. I would recommend it on a long wire but it will pick up stations off the supply antenna I would love to see a small waterfall on it
I like the reciever. When you TX on live stream this is what I use along with 100 feet of wire to try and hear you from east Australia. Nice RX for grab and go,
Awesome! Thank you very much! 😊👍
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.
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...
Thanks for your honest non biased review.
There are other models of these and experimental firmwares also. I think it is a hit and miss if you get a decent one or not.
Thanks for sharing 73
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.
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.... 🤪👍🏼
FYI: If you have a digital antenna you will need to get a BNC male adapter to replace the antenna it comes with.
Great demo, you covered it well. A very interesting radio! Looks like it would last a long time, I don’t see any failure prone components with the proper care. Thank you!
I finally got mine yesterday after sitting on a boat for 2 months but it's more than what I expected my voltmeter works and it has on FM lyrics or whatever the station wants you to know on screen the ham bands and single side band is very important but it also on ham Band .. what they call Px is CB radio..
Good video. I like that you opened it up. That was my first peak inside. To bad they didn't use an easily replaced battery.
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
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.
Nice video. Thanks for sharing. 73 de PU2CLR.
Very nice over view of this radio!!👍
Thank you! 😊
Brilliant review, I appreciate the info as I am new to ham radio. I think its good value for the price and features. :)
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
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.
An interesting little radio and very well presented.
Thanks for sharing
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。
Well thank you very much for a great review. I was hoping for such before I added it to my present collection of 78 receivers in my shack.i agree with your questioning on some of the features that were missing such as the filters absent. Best regards. Ron. Z.
I'm glad Chinese manufacturers are turning to ham market! I have the previous version, ats-20 that I got for 25$ as a kit and that one works well too. I hope that in a few years we will have a lot of cheap and useful transceivers to chose from as well. Maybe with some willing or unwilling help from western engineers :)
Currently they (chinese manufacturers) have problems with import radio equipments without CE certification in to EU. European rules.
@@OM0ET Let it not be Chinese problem.
@@RickGreenPhoto is it a real UV-5R or is it a variant ?
@@RickGreenPhoto I'm asking because my UV-5R doesn't produce much of any spurious emissions (no more or less than the "higher end" radios from yaesu and icom).

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.
Thanks a lot! I wanted to buy one, but thanks to you, I realized that this is another Chinese "fast food" radio.
Wow. Pretty neat. And a really good explanation! I will note that when you are receiving a signal and you have audio, your current consumption will go up quite a bit. Still, I'll bet that you can get a good 8 hour day out of it.
Thanks a lot for sharing this stuff in the video
Interesting little receiver.
Please take a video on how to flash this radio? Thank you very much! 73!
Good idea! 😉👍
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.
Very well done, thorough, impressive video review. Thank you WB9DZS
Many thanks for your excellent review. I did buy a Tecsun PL 880, but when it arrived it was practically dead, so I returned it. After your review on the ATS-25, I went ahead & bought it, & at just over £85 including delivery, I think it is well worth it, & I was not disappointed. I was surprised how many stations SW, & HF Amateur Radio it will pick up with just the whip antenna. 73 de Pete GI0FZT.
Oh I am so happy that my video helped you to choose the receiver for your needs 😉👍 Thank you for watching my video!
Where and who did you purchase it from?
I ordered it from Ali Express Darren.
@@peterfrend5360 Ok. Thanks. However, I am on their website now and I don't understand why they sell it at about 5 different prices.
@@darrenrogers5174 Mine cost £79 odd & £86 delivered. Some are different looking, but I chose this one same as video.
Жаль что такой красивый приемник с отсутствием селективных цепей по входу остается красивой игрушкой.
Just add filters, attenuator, ptt to protect from xmitter, and waterfall to make this a useful addition to the ham shack.
The AGC setting is actually an attenuator. As for waterfall - why bother ? I'd rather listen to signals than watch pointless waveforms.
Looks good, would like to have one!
I found mine particularly good for NDB hunting with a 5M wire attached
NDB's still around?? Haha
Good idea with the photo tripod 👍🙂
Thank You for a very informative video Sir. Put one on my list FOR SURE
А где полноценные диапазонные фильтры? В городе этот приемник без фильтров бесполезен. И никакая, как Вы говорите селективная антенна их не заменит!
Very good video my friend, 73 to PY2LSB.
Very interesting, but, very expensive receiver.
Thank you
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... 😉
Like to see/hear more about the antenna you use outdoors in this video.
I love it good
Keep uploading videos like this 👍
Thanks for your support and watching my videos! 😉👍
Very good, thanks for this nice video!
It looks like a nice radio to take on the road or use at home. If you think that this radio will replace an Icom or Kenwood, it won't. Its a cheap radio made for fun.
Is the am/fm CB channels?
It covers up to 30mhz, and has a switch on the back for FM
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.
try some speaker wire you can make them into antennas
Great review brilliant can please ask which would you recommend this one or a xhdata 808
Well, your estimate of usage based on the battery's capacity is a bit off since you'll never get that unless you're fully discharging your battery to zero...
Actually yes, you are correct. Practically it will be less 👍
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 😀
good review of the radio. thanks.
To many unanswered questions about the frequencies,and mode specifications .
?
awesome design
Very informative for potential buyers.
Thank you! 😉👍
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 😃
Hello and thank you for the video, but you can listen to the bands aeronautical. Thanks
Good video , easy to understand.
Thailand.
Depends on what the capacity of the battery is that is inside the unit too, and what you’re saying about it sounds to me like it could be a good little radio. Grundig makes some good radios too bad the lower end radios only receive AM on all bands below the vhf broadcast band from 88.9 to 108.1 MHz which sucks because I love recording SSB as well as am dx. The only way I am able to really do dx is via remote hams and I wanna be portable at certain times.
He says in the video what the battery capacity is ... 🙄
Seems a very nice, feature-rich package for about $125. What do you think of the smaller Malachite SDR with a waterfall display?
Yes, Malachite is also great pocket buddy which is with me all the time and everywhere 😃 But this ATS25 has bigger half-empty enclosure, which means free space for experimenting wiyh some homemade addons for long winter nights 😊
A RTL-SDR mounted inside the case, with usb and antenna terminals for it. Then a mini pc to get your waterfall and sdr ops. Would be a nice upgrade.
Possibly a 9 to 1 balun inside for random wire antennas
Can it work for am radio stations also?
Fm music and AM medium wa ve bcst. FM sounds fine.
Where are the full range filters? In the city, this receiver is useless without filters. And no, as you say, a selective antenna will replace them!
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
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.🤨
No need to ask if it is SDR or conventional ;-)
I would be curious how a conventional receiver compares to this ATS-25
It is conventional, the SI receiver chips are used in many popular SW receivers
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!
Very Good! Thanks 73 (Brasil)
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.
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.

Thanks..vary good
Yi1hra.....73" from baghdad
I'd probably use a rubber tipped stylus for the touch screen.
Yes, good idea!
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
would have liked to see u test it with its supplied telescopic antenna...& not just the 40m band...all the bands...thanks anyway
Listening on supplied whip antenna is noisy due to picking up the noise from display
Thanks, nice review ... what is the point of having an S-meter when the level never changes?! Also it doesn't seem to be calibrated because usually when you scroll through the band in 0.5 or 1 KHz steps most of the time you don't need any fine tuning and are spot on because many hams have very precise oscillators these days. I have no clue what it costs, your links are obsolete, but I prefer a Malahit SDRs, where you can see the entire spectrum and have many modes synchronous AM & Sideband and bandwidth and preamps and attenuators ... amazing IF DSP filters, many memories that store all the detailed settings ... have the aircraft band and other great stuff up to 200 MHz or 2 GHz. Even the cheap Chinese clones are pretty amazing.
Boleh juga simple dan unik.. Sdh di produksi dan sdh ada di jual di pasaran..

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.
Paul which camera was used in the video? The receiver looks like a good format but I would miss the waterfall.
Camera is Samsung Galaxy S21ultra.
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"?
excellent review thanks
Nice. I want one!
we are good at make the aluminum enclosure for this enclosure
You mean something like a carrying box?
