Mine will be here tomorrow! It’s rare to see the person who invented your radio be public and proud of their work
The user interface is so incredibly well designed - it even beats some of those commercial rigs! Well done!
Except the buttons often do unexpected things, not what you expect.
Got one two weeks ago, truly amazing. it's backpacker's dream came true. it's by the hiker and for the hiker. THANKS!
Thanks for such a comprehensive and informative video. This tiny rig encapsulates every thing that has fed my enthusiasm for "ham radio" over the past 59 years - an enjoyable learning curve provided by other enthusiasts keen to share their expertise, the ability to experiment and best of all, amazing performance for minimal outlay. This tiny "box of matches" provides more satisfaction than all the "big brothers" in my shack. QSO's far and wide in CW and SSB including China from the UK!! Simply superb. Thanks and 73, Roger G3SNT
Thank you so much for the kind words. You made my day ! 73 Manuel; DL2MAN
Manuel, thanks for this amazing rig. It has enabled me to create an ultra portable station that can fit in my EDC Bag. Now no excuse for impromptu SOTA/POTA activations, or for any unplanned operation while exercising on the bike or going outdoors. We'll done! 73 de Luis, HB9HJU
I just saw this unit. Once I saw it in green I had to see what it is capable of. Now, well now I have to buy one. I both love and hate this hobby. Great work!
Great job on the radio. I continue to be impressed as I keep using it.
Just got mine 8-16-23.
Great explanation
Thank you Manual for a very comprehensive description and demonstration. I am waiting for my unit to arrive.
Realy compresive explanation👍Thank you for your help! 4z9dei
Thank you for the great, great radio! I'm having SO much fun with it. I've been using it mostly portable including some POTA activations. vy 73 Ron
Thanks so much for creating this tiny amazing tranceiver, i am going to buy one in the next few days and look forward to some ft8
I have a usdr, but I have to have one of these little jewels. I’ve never seen so much in such a tiny box. Great video. Subbed.
Thank you for engineering such an awesome little radio!
Thank you for your contributions to amateur radio!
Thanks for the walk thru of the functions. I have two and planning on getting third, one for each RF board. (LO, HI and Classic)
Does it come assembled and did you grab them on Amazon or eBay? I just want to make sure I grab one from an official source. 73 de KM4UUD
Like watching a great movie. So informative! I'm ready to get on the air. Thanks so much!!
Love your channel! I just received the (tr)uSDX and am putting together my power pack, antenna etc. Is there a .pdf or similar file that has instructions? I found your site with the sheet that has which buttons do what, but a .pdf that we could print out showing each function and the recommended settings would be amazing. Keep up the great videos! Can't wait till all my stuff arrives so I can head out and have fun....with beer!
Thanks great video
I needed that
Thank you very helpful.
Built my third one, now. Currently testing. Power is fine on 80 metres, but low on the other bands. Need to use your alignment video.
i have the components and 3d printed case in a bag ready to go. just waiting on new spectacles. To be able to see the the bits lol.
My guess is that the "gate" refers to what is usually called "Nose gate" which is like setting the vox threshold level so that between speach elements an alc does not amplify the pin drop minor background noises that you don't want to transmit. Only when there is a high enough level of input does the sound become allowed and then what ever processing/compression/alc that is set becomes implemented.
Do you mean Noise Gate?
Hi Manuel. You two guys have created a great thing. I have built two now, one unfortunately blew up due to my error but am getting some parts to repair it. Silly mistake. My second one now works great. Good long rang contacts here in VK. I have a question re the Tx audio. My reports back were some noise and crackling.? I have feed Tx into my FT991A and it does appear to have some digital noise. Is this normal or can it be cleaned up. Not sure how clean the audio should be via the ADCs on the Atmeg. Audio sensitivity is good just a bit noisy. Do you have any suggestions for me. I am a very technical guy and do this for a living however I’m a hard ware man not software. But a dam great little radio. Regards. Richard VK2VD.
That Noise comes usually from a loose Antenna Connector. I´d try to re-solder the SMA Socket and use an SMA Connector for your Antenna (no BNC Adapter) to see if it gets better. Because SMA is screwed on and prevents movement. Other Idea would be to change microphone. They are sensitive to damage if soldered too long.
Excellent and very informative video Manuel.
Thanks for all the work on this project.
Regards Trevor 2M0GZQ
???what microphone can I use with this unit????
Very nice overview. One question on the keyer: I see straight and Iambic. Is there a way to use a single-paddle key, like a Vibrokeyer, or only twin-paddles or a straight key?
I´m not sure, to be honest. Never used one before. But I assume it has also 2 contacts (one for dah and one for dit) ? So it should still work with IAMBIC Keyer, exept, that you can´t use squeeze techique. 73 Manuel; DL2MAN
Amazing little radios
Takes me back to the days of building and playing around with DC receivers with amazing results
Looking thru eBay last week
a little usdx black box popped up
And since I was playing around with a blekok 7mhz tx rx I ended up buying 1
I then went looking for videos on these and found you Manuel
Needles to say the black box is a bit iffy and knowing now what you have been saying about the tr u sdx
I'm wishing I would have seen yours first
My usdx a fun little rx if nothing else but I must now get one of the tr u sdx radios to go qrp with a clean signal

Hi, I will like to see some audio tests in am and fm, I saw some performed in cb band in youtube. 73´s thanks in advance
Why did they use a tiny connector for the 12 volt input that nothing fits instead of a normal size one? Also my radio is ver. 2.00x and all the control buttons seem flaky and do odd things a lot of the time. Is there an update to make it more stable?
What can i do, If the CW loop doesn‘t work anymore? I burnt the Transistor because the loop started to transmit without antenna. Now i changed the transistor. But CW loop message doesn’t work anymore. Could it help to reflash the Firmware?
I removed the powercable to stop transmiting.
Is there an external microphone that can be used for (tr)uSDX directly, without modification? Microphone only.
Not that I know of, but soldering a wire to a connector is not as hard as you might think. There are even instructions for you: forum.dl2man.de/viewtopic.php?t=392
Thank you for this video! Is there a way to display the serial number of the radio?
Tnx de Arnie W8DU
There will be probably a menu option in the near Future. Right now you can only have it shown by either programming Bootloader via ISP Header, or program a firmware with a wrong Serial Number.
@@dl2man Danke!
@@arniep740 Sehr gerne ;)
Hi Manuel, I received the Trusdx today. When i swich bands i see 3-5-7-10 and 14.000.00 is this correct? I'm a newbie and think the bands are not ok, please explain.
Sorry Manuel, i checked and i understand that everything is ok. Sorry for bothering you.
Hi Manuel, I am very interested in getting one of your radios. Does it come assembled and ready togo? And where is the best place to get one? 73 de KM4UUD ✌️

Thanks for all your videos. Where is the best place to purchase one. K7WHN

I want to know if AM mode is receive only OR uSDX can transmitt AM !
It can TX in AM as well. But keep in mind, this is more proof of concept, rather then full featured AM Transmitter. 73 Manuel; DL2MAN
Awesome, Thanks for making this video! I just built mine and my brother is working on his so this will be helpful!!- KC1RFJ
Are the ones offered on Amazon yours or are they bootlegged ones?
I cannot tell from the distance. If you want to be sure, use the links on my page: dl2man.de/where-to-buy-trusdx/
I'm a newbie and the technical terms are very intimidating. Where can I find more information so I understand what you are talking about?
There's a lot of basic amateur radio training on CZcams. I would start there.
Should the internal speaker remain on when using external speaker?
No. The 3,5mm Socket has a switch, that should disconnect the onboard speaker when something is plugged in.
@@dl2man thanks. Then mine’s broken. I will look for solder shorting something first step.
Were can I buy this truusdx here in d Philippines 🇵🇭?

How can I get one of these little rigs?

Is it any danger in running ft8 on full power with this rig?
With Efficiency tuned above 80% and a well matching Antenna: No Problem. The Problem starts if one of those 2 conditions are no fulfilled. 73 Manuel; DL2MAN
Any recommendations for an external mic?

Where can I order this pre-built and tested?

My rig is malfunctioning. When I choose a menu item and hit Menu to save and exit it wont exit.
Try a reset and/or re-installing bootloader/firmware. If it doesn´t fix your problem, start troubleshooting it. The buttons are really no witchery.
@@dl2man Update instructions say "Select programmer: Arduino" but the choices I see are:
Arduino board as programmer using Arduino as ISP firmware
Arduino for bootloader using STK 500 v1 protocol
Arduino Gemma bootloader disguised as USBtiny
Arduino ISP programmer
Arduino ISP programmer
Arduino: FT232R connected to ISP
Arduino: FT232R connected to ISP
What should I choose?
Hi Manual. Can i buy an assembled version? 73
dl2man.de/where-to-buy-trusdx/
Stupid question: How do you turn it off?
Just disconnect the Power supply. There is no "soft off" and the one we had was removed in newer firmware, as it was suggesting it was off, while your battery was still drained.....
mics on cameras are worthless
Manuel... just a quick question. Thanks to my friends from roWaves I got my hands on one... and how amazing this little thing is. The question... as I know at first there was no speaker. If I remove it now... there is any issue ? I love using headphones anyway. Thanks so much... and one more thank you for all the work you put into creating it. Its amazing. 73 DE YO6DXE.
No Problem, if you remove the Speaker. Just unsolder it and be good. 73 Manuel, DL2MAN
@@dl2man Perfect. Thank you so much. 73
Absolutely brilliant. I have to have one of these! 73 de KB2HSH
thank you for this konten information, de YC0SJA 😁
I just ordered the classic. Trying to remember if they asked for my call sign. 🙄 I think they did. I’m not much of a programmer. Especially if it’s that bootloader stuff. Yikes! Winding toroids is fine. Done a lot of that building mtr (kd1jv) kits. de n5vwn
Mainboard definately comes with bootloader, so worst case would be: You need to upload firmware via USB Cable. Easy to do: dl2man.de/3b-trusdx-firmware/
