Hello Guido,

Tried to contact you directly several times by email, but I didn't received any answer for you , so I post here again. I currently have one (tr)uSDX borrowed from a friend. I really want to fully support it in Pocket RxTx v4 I'm working on. For the ones interested, it is available for download as an experimental version here: https://prxtx.yo3ggx.ro/exp.html and already has minimal support for (tr)uSDX) (frequency, mode and PTT). Please just tell me if you are still interested. if not, then I will return it as I keep it just for this purpose.

Thank you,
73 Dan YO3GGX

Thanks for congrats and reaching out to us.

It would indeed be great to have Pocket RxTx support for the (tr)uSDX.
The (tr)uSDX is loosly implementing the TS480 CAT protocol [1]; make sure to keep DTR stable (as it is used for resetting the rig during programming). RTS is used for keying the rig in CW. The list of currently supported cmds is [2].

We are having a development firmware that also is capable of streaming audio over the same CAT connection, a special CAT command is used to enable it and to make distinction between the other CAT commands. In this way Pocket RxTx could make the receiver audio audible via the phone speaker and use this for showing a waterfall and/or doing some digital modes decoding (is Pocket RxTx supporting digit modes?). Also audio streaming for TX is coming.

Please reach out in private to my personal email: pe1nnz (at) amsat.org and we can work together if you like.

73, Guido

hello, to do the tests on the high bands, without tampering with the original version, I would like to buy only the pcb with the RF part, is it possible?

Classic and High Band RF Boards are on the Way to me for evaluation.
Once we have tested, they will be available via Sunny.

Is the source code for the (tr)uSDX available? I tried compiling the uSDX (https://github.com/threeme3/usdx) with various flags but it is not quite the same as the official firmware. The repo has not been updated for 4 months. Is there another repository somewhere housing the latest (tr)uSDX source code?

Why can't one search for that contain relevant keywords? Most of my searches end with being told the word is too common. For example, I am in the General Information for 'firmware' and it won't do it because it is too common. Maybe so, but it is also relevant to my search and about the only keyword I can think of to find information on the firmware.

@N6WLM
No, the source code for (tr)uSDX is not available. (tr)uSDX is Creative Commons, but not open source.

@RichardB:
This setting was enabled by default in the forum software. I´ve disabled it now.

Hi! What is the safe range of antenna SWR that uSDX can operate with?

How closely should the 470nF C25-28 caps be matched to keep the two sides of the Tayloe detector tightly balanced?
0.1%, 1%, 2%, 5%,10%, or 20% caps? Some times it's cheaper to buy a bunch of 10% parts than to get four 1% ones, and then out of the bunch find four that are within a couple percent of each other, so not spot on for the nominal value, but pretty well matched to each other.
So the question how closely matched to each other, do you think the parts need to be to get the best performance you can when listening by ear (as opposed to measuring with high tech precision equipment).

Hi Manuel,

Please take a look at this thread:

viewtopic.php?t=602

I'm hoping you could implement this modification in the next revision of the PCB. I'm interested in your thoughts about it.

Also, I'm curious what Layout software you used to design the PCB. I'm a professional PCB designer (New Horizon's Probe, Mars Rover, Kepler, and many more). I couldn't help but inspect the gerbers. ;)

Oh, nevermind. KiCad. I see it in the schematics title block.

Two questions to the development team:
  • 1. I believe that you are working on adding USB audio streaming. Do you have any, even rough ETA on a stable firmware release with that feature? Use case: single-cable operation reduces cables clutter and weight for digital modes SOTA-kind of operations.
  • 2. By any chance, are you also working on adding FULL support for CAT control or any other serial commands via USB? I believe some CAT commands work, like changing the frequency but not all. It would be great if it was possible to change mode, enable VOX, measure SWR just by running some commands via USB. Use case: operating the radio remotely.
Thanks
