I’ve had this radio for about a month now and have had a lot of fun with it. I had more QSO’s on field day than with my larger Yaesu rig. Only thing I would want to change is the tuning knob. When I put it in my bag afraid of snapping it off.

FYI TX Drive changes the speech compression. Quote from DL2MAN. (tr)uSDX comes with native Speech Compression. Level can bet set in Menu 3.3 "TX Drive". Level 1 is Linear Level 4 is alround compromise (Good Compression, good audability) Level 8 is removing all the Amplitude Information, and regardless if you whisper or shout, it will always TX Full Power (at the expense of speech quality).

Very interesting video. A friend of mine and me built our own tr(u)sdx radios from a kit, we got from Manuel, and we love it. Please do more videos on the tr(u)sdx.

I'd love more vids as you assemble your portable station, select external accessories, key, mic, power, etc. And a few more on deployment, set-up and use. Keep 'em coming! 73 de WZ9U

What a fun looking radio....good for someone thinking about some fun in the field and want to keep cost, weight and space down to a minimum.

Nice video as usual, hope you do more videos about (tr)uSDX specially field tests, that would be so informative Thank you

Great video, was looking for a QRP radio that I can safely take out in the sea, not fancying taking the IC705 near the salt water - reckon I can use the truSDX Peter VK3YE style with a vertical and a ground strap for some spring-time paddling once the weather gets better here in the UK!

Thanks for the very informative video. And an extra thank you for the pleasant English speed, which makes it understandable even for me with a different beak.Hi

it is a wonderful little transceiver! I love mine!

I would definitely like to see “field” operations with the QRP radio.

I've come to think of the (tr)uSDX as a "pre-QSX". It has many of the features at a size and price described by Hans G0UPL for the QSX many moons ago. The (tr)uSDX team and current owners/experimenters are currently working on implementation of the higher HF bands. The only thing missing then from what was described for the QSX would be an onboard sound card.

That’s a very impressive wee radio Matt thanks for showing it! 73 Chris Gm4zji

That USB port also has CAT control FYI

Is this company still a distributor? I found the company but no (tr) usdr anywhere!

wow great product! be great to see you do pota with it, 73s for now

Trying to find one to buy. Cant see it on the uk amazon store..

So this is a closed source for the firmware? No way of upgrading otherwise? What if I change my call sign?

(tr) uSDX its real fun and true QRP fun, I love mine !!!

yes please

Very nice video! Thanks for your info and detail! Cheers & 73! Tom - WA7FLY

I really recommend ROwaves. All the best from Romania!

god i love these qrp radio's that matt reviews, great for coast walks and pota, but i have more fun using all my budget qrp radio collection with my RM Italy BLA-600, yeah i know it defeats the object but when your qso is about conditions it gets a laugh both ways, especially the audio quality ect

I like this radio. But I think I’ll wait for 15,10 meter options. Or better yet. 10,12,15,18 meters. I can only dream of 6 meters!

QRP/P demo gets my vote.

4:24 I didn't know Daleks use ham radio!

Interesting, but I'd like to see a radio with an integrated sound card for digital modes.

Neat little device, shouldnt have the firmware locked down like this though. Luckily it should be no problem getting around that. People will clone it, but if it was an open source project, we could at least send a donation to the creators after we buy the clone. Look at MMDVM, buy the clone and send the project a $20 donation, everybody gets more money. Since this is trying to be proprietary, that is likely impossible.

Please test it on AM and FM, and try to get some info on mods for improvement...

This could be perfect for SOTA operations!

Neat idea for such versatile standalone pocket radio, very likeable! But this gatekeeping with baked serial and callsign into firmware? Wow thats amazingly bad

Really want to buy this, but not having 15m is a dealbreaker. I know they have a board to add it, but the price gets much higher to do so.

Would be nice if we could hook it to a computer for FT8 ops.

I find it a bit disapointing that you're not refering to what actualy is going on here. There are many cheap small SDR radio's available, the major differences are here * The fact that Guido uses a 8 bit Atmel processor like is used on Arduino boards This CPU is absolutely not equiped to do this kind of work, stil it does ! * The way how Guido creates the different modes differs from the usual I/Q dual mixer method Al to be found on his webside. * After software upgrade a couple of verry nice features have become available like build in option that eliminates the need for a sound modem if you're doing digital modes, and even a spectrum display on the tiny little screen. * You're demo shows USB with 4kc bandwith... who would do that these days. 1.8kc would be much more convenient. * You have to get use to the control, but there's a lot more you can do with the rotary dial and the little pushbutttons, avoiding the need to dive into the menu's Ergo, this radio is a genious peace of work, which sadly is hardly recognized.

I echo ko ko Tom Maynard's comments below. You offer us knowledge and adventure. Please take that little beauty out portable and find a tree! 73 G7OGX

How much does it cost?

Ummm wait so you have to have a number to update. I love just listening as I don’t have a license so not very good then ? Listen to radio for years would never transmit though.

RoWave no longer an approved official supplier

I have this radio and the uSDX+ and the clone is a dramaticly better unit, thus far this was a big dissapointment, bu I will continue messing about with the thing to see if it grows on me

first

Open-source, creative commons expects copies to be made. There are no clones. Better check your Baofeng too

I suspect that the locked down firmware is to stop any Tom Dick or Harry from using it without a licence.

O kit mais chato de montar que ja montei, falta documentação a opção por vídeos é uma coisa muito chata.

Boomers sure do love proprietary software. I refuse to buy this because its closed.
