No Mark, you are not an expert. You are the only expert on the uSDX from what I've seen. Keep up the good work. By the way, I've noticed a pretty good spike in your subscriptions.

Thanks for this. Very distorted tx audio on my uSDX that arrived today. Your settings have made it a lot better.

Thanks these setting cleaned up my tx distortion

Thank you. This was an excellent introductory walkthrough for the usdx and I've learned a ton from you already.

Thanks for the suggestions. Just received mine - I appreciate the guidance on both the setting levels and translating the setting definitions. Good work! De AE6FE

Hi Mark, many thanks for this clear and thorough test. Greetings from Italy, 72 de IK2RGV 👋

Got My uSDR today and set it up like You said I was on 40m Made 2 contacts the first time I keyed the Mic My Ant is a 65 foot long wire no tuner and got a 5-8 report one station was 50 miles and the other was 178 miles away this was at 7:30 pm EST works grate ! and I was running only 3.6 watts

Congratulations, it's one of the most coherent videos I've seen about these Chinese QRP's, there are people who don't understand that for less than 100 U$S, you can't have a device with the features and quality of an Elecraft.😏 73

Hi, Thanks for nice videos! A tip (don’t know if you have fiund out yet): Push the function knob in and then turn while pushing and you have instant volume control! Cheers from an SWL (soon to be livensed) in Sweden

I found that if you hold the main button on whilst connecting up the supply it restores the radio back to original. It fixed the USB/LSB problem I had.

This helps. Thanks for the clear explanations.

17:05 Menu option 1.7 RIT - The “RIT” refers to “Receiver Incremental Tuning”. It’s a feature that allows you to slightly adjust the receive frequency without changing the transmit frequency, which can be useful for tuning in a station that’s slightly off frequency.

Very helpful. My uSDX board has just arrived from Romania.. EI6AU

thank u for u intruction explications whis my antenna 20 watts just changed whis de cable modification on my antenna my connection perfect u setting thank u cool

Hej Mark, ist's a real pleasure to listen, watch and try to understand what u are telling! It's funny, I was OFF for 40 years and one week ago I tried to check if amateur radio still exists (hi)... Just few hours before I found your channel I ordered this uSDX TODAY from china, and now I can learn a lot from u to start with - when hopefully it arrives in day's week's...year's...lightyear's... And who knows if my yeasu FT-221R (2m) and my FT-101E somewhere in a box in the house still work when I try to plug them in again..? So, u are doing a great job I think, and for oldschool OM's like me it feels very very well! Hope to hear u soon - from uSDX to uSDX / OM to OM :-) 73, DF7RO (Michael)

Yeah it’s strange it was ok. I found if you hit the main button twice quick it steps up through the bands.

Very much appreciated. Thanks

Very helpful. Thank you sir. 73 WA6MOW in Los Angeles

Tanks verry good vidéo, 👌

Thanks, this helps.

Thanks Mark!

Great video. Sub'd

Thanks !

Just curious if the output power is adjustable? Or is it just BIAS? Thanks for the awesome info! 👍👍👍

Great video! I've been looking for a radio like yours, and I bought the same one. It's been a long time since I even thought about getting into these frequencies aside of 2 meters. Could you please give me the parts I need to put you an antenna system like you have. I'm not sure of what I need. I have no room for an outdoor antenna. Please do write a manual for this radio, I would surely appreciate it. I'm now a subscriber to your channel.

Noise Gate , IS the unique form regulate distorsión in ssb this transceiver no have ALC good settings For speech modulation

Hello thanks for the video please let me know what antenna tuner and antenna you use thank you.

Took mine for a walk the other evening. 1300km contact into vk4. Video on channel. VK1MIC

Start at 12:10

Thanks for the info.. Only thing I'm not sure of is the SWR meter how do you use that?

if you double tap the vfo it flicks through the bands,

The 6m and 10m bug... is there more material out there about it?

I've one of these radios on the way. Would I be correct that I'd also need an antenna tuner/swr meter for this multiband radio?

So far I like it but it's off freq I am sure it has an adjustment but not sure how to implement it

Ive got issues trying to send data... Got the CAT lead working but it wont come out of TX, got the KEY/MIC lead set up as the (tr)sdx suggests the HP is straight forward... Cant seem to find answers...

Can you tell me what does the right hand "Exit" button do ? Thanks, Mike

Is that a swan 350 there i see just the corner of just to the right of the uSDRX?

Is it possible to talk to the citizen band in the 27 mhz band?

I'm over the Moon. Mine arrived today & with the help from your video, I have set it up & am amazed at how good it is for such a low price too. Thnx for the very Helpful Video mate. 73 de VK3VKe ⚡🙏⚡

(: hi Did you set up the device yourself using a circuit diagram from the internet? Wow, how exactly did you go about doing that?

Hi Mark, my usdx is out of frequency more than 2 khz. Instead of the original ref. frequency :27000000, I had to enter 26996550. That's works for 20 and 40 meters but for 21 and 28 I should correct more. Does anyone have the same problem? Thanks

i dont know if you could help me. i am getting very tired of this. my uSDX+ has missing menu option. i cannot find menu 3.1 VOX option. as i cannot enable VOX it render FT8/JS8-call impossible.

Iv just got one today. But I find it not very good on FM audio is off frequency 11 meters

I just got one of these they are tiny .

Will this do UK CB? or is it Band Limited?

The radio now receives on USB but transmits on LSB and is again distorted !

One thing I don’t know how to do is actually start the cw beacon / stored message. Lol

How do you set the power output????

What would be your recommended settings for CW practice with. alternately, a straight key and dual paddle? Many thanks!

There is mars mod for this item???

Mars mod for this.... .

Sorry bad spell check after having my usdx for about 1 year .

Does this radio have a battery

How much money ?
