Thanks for another excellent video! Just got mine, and I have two questions: I. Is it possible to regulate the output power? II. How to get a side tone?

Nice set and nice review but the TX audio is shocking.

I have the usdr+ set up on FT8, , it works fine if a bit flakey. I started with using a USB sound card and the Vox setting on the radio, this worked but a lot of confusion with the volume settings and various outputs. I then moved to the sound card plus CAT controller and that works much better. You get basic frequency change facilities but the huge benefit is not having to use VOX

You can't go too far wrong at $318 AUD if you are willing to tinker. Sure its no iCOM 7300 but it'll get you on the air and with a bit of tinkering you can make it sound fairly decent. Getting on HF has always had a big price barrier for new hams. This may be the ticket to lowering the bar to entry into HF. Now I might own a 7300, but my problem is room - I don't have the space to get on the lower bands!

Is there any explanation of the PROG-CAT switch and the USB-TTL switch? can you update the firmware from one of the back ports?

[KDZHF]

I love watching your videos. Your storage must be overflowing. Do you keep everything you review?

[joeblow]

How is it on CW? How are the harmonics? Does it have a clean output?

Interested in some specific critical settings. heard it is easy to crisp the finals. especially Noise gate, PA bias min and PA Bias MAX. Any guidance on setting this radio appreciated. Ed W6AOA Pensacola, FL

Wish you would have set up the TX audio correctly and tested it, you'll be good to know if it's garbage or not

[TheSillyshyguy]

Do you know if anyone has instructions on how to set this up for CAT Control?

I bought this and set it up according to the recommended settings I googled and it works just fine for me.
For $260.00 Canadian it's a good buy for what you get.

That BNC patch looked like 75 ohm connectors?

[rayarthur]

(If it costs 20 times more) I would expect the radio to be considerably better.

[migalito]

I think the power level is adjustable, correct?

[eacuatrogndecoalfagnd]

the power 12 v 1.5 amp is very bad to transceiver i think realy the amperes have 2 amp for this type of transceiver need more power is very just for 4 watts and function menu i recomended use AGC SLOW becuse the volume is more stable for the procesed audio signal for audio tx distorsion open the transceiver and put into electrect microphone one capacitor between positve and negative electrect microphone conexion to RF distorsion is very miracle solution to audio tx

Very nice rig but availability in india ?

[dogastus]

Certainly a cheap way to get on the air.

Reçu et essaye aujourd’hui
Pas de haut parleur sauf avec micro en ssb
Tuner inefficace sur 15 et 10 m
Puissance très faible sur ces fréquences
Fonctionne assez bien sur 20, 30, 40, 80 m
Pas de Qsk en CW
Vraiment pas cher mais vaut pas cher non plus : mon USDR plus coins rouges est meilleur de très loin.

Please can you open and show me?thanks

Arrived my uSOTA-ATU.
It came with the LCD of the SOTA badly soldered and it was being pushed out of place by the front panel. Fixed it, not 100% perfect but didn't want mess too much, but good enough to can note it.

What is more worrying I was receiving in 40M a comm in the same frequency in my Malahit SDR2 and my cheap UV-K5 with SI4732 mod. But in the uSOTA-ATU this same signal was displaced 3khz to listen it respect the other radios. WTF!

Is this normal? Will it transmit off of frequency too?

In other way it looks a cool little device by the £141 it cost.

Can you try the freq deviation?

Thank you for this test. In Italy you can buy it for less than 200 Euros, about 200 dollars shipped home. Surely it's not a competition apparatus but... it works decently. 👋👋
