SSB Receiver ATS-25 Max DECODER (LW, MW, SW, CB, FM) Review

This radio shares most of the features with the ATS120, which I detailed here: • New SSB Pocket Receive...
Link where I purchased this radio: www.aliexpress.com/item/10050...
Link to firmware developer: harduino.ru/index.php/en/software
In this video I try to describe only what this radio has in addition to the ATS120. The second half of the video shows how the radio actually works.
Pro's:
+ new improved original firmware (harduino.ru) with activated license key
+ large speaker
+ automatic internal SW/FM antenna switch
+ mobile radio form factor
+ 3000mAh LiPo internal battery
+ aluminum alloy box
+ large tuning knob
+ new 4 types of graphic S-meters (BAR, ANALOG, Audio-SPECTRUM, Audio-WATERFALL)
+ digital decoders for FT-8, FT-4, RTTY, CW, HELL (more will be added in the future)
+ functional RDS when receiving FM
+ indicator of the quality of radio wave propagation
+ receiver's system time synchronization via WiFi or RDS
Con's:
- additional LNA (preamplifier) is missing
- high pitch sound when the audio is muted when AGC is on
- reception of strong interference (QRM) from the screen when the internal antenna is connected directly to the BNC socket(telescopic whip)

The 4.16 air not the beta version will add Bluetooth, LNA, HiZ, and Lock. The activation button will be between the WiFi and volume. Also the max decoder has a new power scheme which make the display illumination more stable and less flickering. On the max decoder the waterfall now actually works giving actual visual information. I like your content and professionalism Paul. Thanks.

[@OM0ET]

Thank you very much for your comment! ;)

[@ominkan3129]

Since buying the max Decoder and having, firmware 4.17 beta air installed, I found there is no BT, LNA or Hi-Z antenna setting features in the radio. Disappointing. So Paul could you do a video on adding those features to your max Decoder?

[@digitalmediafan]

No LNA and HIZ with me using 4.16 and now FT8 doesn't work either

[@ominkan3129]

@@digitalmediafan I think that is a good reason to be disappointed, as I was to find no LNA, BT or Hi-Z after I was told the max Decoder handled all firmware features.

[@OM0ET]

There will be a new version of ATS120 soon with those features. Hope I will be able to test it 😉

[@agustinmoralesrodriguez1242]

Do we need one? No. Do we want one? Yes!🎉😮😊

[@canidsong]

I need another radio like I need another hole in my head. Hold my preferred beverage and pass the cordless drill.

[@leejenkinson5521]

nice video, was I the only one to see the ANT run across at the ATS25 at 16mins 10 seconds lol

[@alasdair4161]

That same ant made his cameo appearance at 11.43

[@NJF60]

The ant seems to like this radio

[@HKey_Root]

Brilliant Paul. Your videos are a revelation. These small inexpensive units like the Quansheng etc are as cheap as chips and worth experimenting with.

[@nordford68]

RBDS is mainly used in the USA…in Europe, we can leave this option switched off. Very nice introduction to this device. Many thx. 73 from Germany

[@m1ian]

Thanks for the video i have just bought a DSP2 and this video has helped me alot in setting it up 73s

[@NJF60]

Thank you Paul for the informative presentation. I’m close to purchasing one to explore all it’s cool features. Your videos are always on point and I enjoy watching them. Regards, John from Florida USA

[@OM0ET]

Thank you for watching and for your compliment! :)

[@winstondeegbe3566]

I really do enjoy your video presentations Paul. It's easy to understand you and I learn a lot from you. Did you ever cover the tropical broadcast bands using the Max Decoder II ? If you have please share the link.

[@ronalddaub9740]

Outside of the waterfall I like the simplicity of my old ats 25 .

[@chuckp3739]

Thank you for the very descriptive video. I will have to add one to my Ham Shack.

[@rlwoodlief]

Great review Paul, thank you. 73's de N4RLW

[@ManuelLausmann-Funktechnik]

Bernhard's software also offers the possibility of time synchronization for FT8 without Internet, but with RDS. Prerequisite, an FM transmitter that sends the time via rds

[@OM0ET]

Thank you!

[@royramdeen8864]

Great review paul..

[@KA9DSL]

Yes I agree, having an FM mode on the short wave bands would be good. Especially when 10M 29.600mhz FM is open and active.

[@antoninorusso56]

Impossible for now ... chip Si4732 non support this function.... But we are working, with the release of the next definitive version of the V 4.17 Air firmware (the beta is already available on the site... and is also BPSK31/63 decoder !!!) with the implementation of the FM mode on the CB band and on the 10 meter band... as well as adding new ranges in all modes, 50 Mhz (6 meters), 144 Mhz (2 meters), Air Band (AM) and Marine band (VHF)... you will find everything in the next firmware (we are finishing the test tests...)

Hi Paul.. Great video as always.. Nice radio.. But i'm really hooked on my ATS120.. Cheers..73s from Australia..

[@OM0ET]

Oh I love also my ATS120 too! :)

[@leejenkinson5521]

would love to see this with some sort of tag/hook to connect to a carabiner, or may be a detachable handle to make it easier to carry and transport, plus some method of storing the antenna and stylus to the side of the case. Just minor points which would be awesome improvements to a future model!.

Thanks Paul. It would be great if it could transmit QRP too. :)

Hi .. excellent review... Does the muting dissapears when you use 1 Khz tuning step in Am SW band ?

Very good clip. I wish you would how to update this radio. You have very detailed things very good.

good job 73s

[@electricite2552]

What camera are you using now? The quality is good❤

[@PreppedScots]

Just placed an order for one of these, gonna test it out with my wee 27mhz telescopic antenna and also my JPC-12 with a 5m telescoping portion just for sheer length on the lower bands just to see how it goes If it performs well then it’s going into a sigint collections kit,gonna be the first time trying out these wee things so fingers crossed

[@NVRMTmotion]

Did it perform well? They're available for a great price at the moment and I've been tempted daily

[@alvarogaitan2529]

thanks, Om0et 73 from kb2uew

[@digitalmediafan]

Hmm FT8 decode seems very sluggish. Even a weak burst should give you a dozen or so stations. CW decoder also doesn't seem very good with what sounded like a fairly strong signal to me. Thanks for great review de M1CTK

[@krzysztofhalupka]

Super - Thanks. When will you make your next video about ats - 25 ? Greetings from Poland.

[@Smash-n-Grab]

Hi OM0ET, I watched your antenna mast install for your hexbeam.. Brilliant install. Loving this radio i just ordered one from Aliexpress but I would like to connect it to a power supply without the battery. Is this possible?

[@_bob_8170]

The Radio Broadcast Data System (RBDS) is the American equivalent of the Radio Data System (RDS) protocol, which is the standard protocol for the distribution and propagation of data by FM radio signals.

[@OM0ET]

Thank you so much! :) I am learning whole life ;)

[@ilijapilipovic]

Stupid

[@jurgenboucher116]

Hi, did you also try the DWD Pinneberg weather RTTY transmission on LW 147KHz? The ATS frequency range starts at 150 KHz, as i know.

[@SangiTariq]

I love your channel. I Love Radio Tariq Hakeem Sangi

[@goranjovic3174]

Very nice radio :) For FM i recomended you to buy one TEF6686 and compare with ATS radios :) )) Pozdrav z Srbsko do Slovensko ! 73s

[@JuanPablo-mt9cz]

Saludos, cual preferia usted la hxdata d808 o la ats25 max decoder, cual es mejor.

[@adrianssolutionsgwm]

DIFFERENT PRICES MODELS the atx25 max is available from 70 pounds to 126 pounds here. For am fm rds is there a diffence or same unit. what is activation paid for, is it relevent to am fm rds I see a wifi aerial on this model but not on other ats25 max .. why.. i assume this isnt internet radio Is the cheaper ats25xi just as good for am fm rds is the speaker/sond quality same for all models, is it really just suck on. IS RDS25MAX A DECENT SOUND QUALITY .. i have a high quality tabletop pure radio right now but menus real hard and cant see buttons in the dark. This looks great to use.

[@ArclampSDR]

I updated mine and its asking for a code I was never given ;(

[@taxineil1]

Does anyone know if the update from 4.16 beta is free or does it cost anything?

[@wtmayhew]

There’s one thing I see on the ATS-120 that also seems to be on the ATS-25 is the mute that seems to happen briefly in SSB mode when the tuning is advanced about 6 KHz, but seems at time to be at irregular intervals. My guess is that it is an internal artifact of the Si4732-A10 radio chip. Does the ATS-25 also have the same problem with picking up images of the FM broadcast band stations in the shortwave band? Where I live in the US, a strong image on an FM station on 89.7 MHz falls right on top of WWV on 10 MHz. Over all the ATS-25 Max Decoder looks very good for the money. It is particularly appealing because it comes with an upgradable version of the Harduino firmware which should help prolong its usefulness. The current version appears to be 4.16. If shoppingmon Chinese web sites, be sure to order a radio with up to date and upgradable firmware.

[@OM0ET]

Yes, seems that both radios are based on the same design. Next version of ATS25 should have front end filters added ;)

[@wrongsideof40]

Great review. Thanks very much! I notice than when you tune in an SSB station, you use 1kHz step size, then go into the BFO for 'exactness'. Does this mean the minimum step-size on the main tuning is 1kHz? If so, what is the point of the two zeros after the decimal point? Thanks again.

[@OM0ET]

No no, sometimes is VFO little shifted and is good to do a small correction trough the BFO.

[@bengeijtenbeek9394]

Hi Paul , thank u for the nice video, i was wondering if there is a firmware with the airband and if so where i can find this? i cant read russian..

[@coinshooters]

hi got one of these receivers , but can't figure out what use the waterfall is? doesn't have a tuneable cursor, also can't enable bluetooth , ? any advice

[@pin00ch]

These things are everywhere and the price spread is HUGE!! I found one for $40 and others for $160. What gives??

[@jeromeGrzelak]

The 160 model comes in a velvet box

[@iliebelcea512]

Questo ricevitore si collega al pskreporter?

I wish they had included a storage hole for the pen. I can see it will soon slip away unnoticed.

[@digitalmediafan]

Something odd has happened I am now unable to get the time so I can't decode any FT8, any ideas why ? Time only works on MW

[@emersonmsd]

Looks good Paul but interacting with the 2,4 ich screen would drive me nuts. I appreciate a bigger screen needs more battery power. The firmware looks great. 73

[@deesalkelly3069]

wish there was a power switch at the front...would like to rack mount a few

[@OM0ET]

Yes, this is very good idea, hope that designer will read this ;)

[@buzzsah]

Does this radio have a mem-scan? Can one enter a few channels to listen to and scan them? Will it pickup Digital?

[@stevec5000]

What kind of u-processor does this radio use to give you all those fancy features? It can't still be a simple Arduino can it? Also just about any radio that has a digital display screen will give you noise from the screen if you try to use a whip antenna so don't do that!

[@mpatrickthomas]

Does it have memory to save frequencies?.I have heard of radios of this type have no memories.

[@adrianssolutionsgwm]

HELP CONFUSED ! What is difference ats24max here and ats24x1 £70. What does wifi do / dig radio??? Why are some 25max £65 and some £120 THX

[@kevargao5031]

I believe the ATS25AMP has LNA, by all the accounts that I have read, the 25AMP is slightly better than the 24 Max Decoder, but hard to judge as there are no comparisons so far.

[@antronx7]

Thanks for doing these reviews so other people don't throw money away on these cheap toys.

[@OM0ET]

There are also many not wealthy people who wish to go in hobby but don't have money to buy expensive radios ;) Thanks god there are chinese manufacturers who made this :)

[@antronx7]

@@OM0ET The problem is these radios have such poor performance that it's better to save up a little extra money for good name brand used radio that will provide much better enjoyment of the hobby.
