tr USDX doesn't work.

Post by Wywhy »

How all. First post to this site.

I have been interested in activating parks and I have been trying to get a go bag ready. I wanted to start out small at first to see how it went. I purchased a tr USDX from Amazon by DL2MAN, but ever since I got it I have not been able to get it going.

I followed the instruction sheet that came with the radio to a T, but it just doesn't work. No matter what I do with the programming, it will not load my call, or work at all.

The sheet said that the serial number should be on the screen and if it isn't there, it could be defective. All it shows is 'trusdx' in the upper corner.

Is there some way to erase the programming and start over, or is there someone who could check it and see if it is defective? Have had no joy with Amazon. I understand it is a compromise radio, but it should at least be able to hear signals.

Would appreciate any help. Thanks and 73.

Hi Tom,

Welcome! I am not a trUSDX user, but I expect others can help. Also, try searching for trUSDX among prior posts. There may be something useful there.

I do want to commend you for testing out your system before setting out for your first activation. When it works, it will give you confidence that you can be successful. When it does not, it gives you the ability to trouble-shoot. It can be really frustrating to get to a park and find out something is missing or not working.

Well done! I'm sure you will get this problem solved.

Thanks Brian


I have been licensed since '54 and have always been able to fix my own stuff, but working on SMD's is a different story. Lots easier to build tube stuff.

I have another rig that I usually keep in my popup camper. It is an older FT-450 that I usually toss that in when I go camping. 73

Tom,
I have a couple of (tr)uSDXs, so I think I can help.
The radio should have come with the serial number on a sheet of paper or something similar. I bought mine as kits and the serial number was on the parts bag.

Are you trying to install the latest firmware using these instructions?
https://dl2man.de/wp-content/uploads/20 ... /beta.html

If you don't know the serial number enter zeros like the instructions say, and the radio will display the actual serial number. Then you enter it into the web page and it will generate the correct firmware.

By the way, the callsign is strictly cosmetic - the radio will work fine with trusdx in the top left.

Good luck with your new radio - these are fun little rigs!

73,
Mike, KL7MJ

Hi Mike
My radio doesn't show the serial number on the screen like it says it should be according to the info that came with it. I do have the serial number on the plastic bag it came in.

The thing that worries me is that right after I purchased it, the listing on Amazon disappeared. No way to post feedback. I assume that was done on purpose. Right now I don't a very good opinion of this radio. Thanks for the reply and 73.
