AliExpress truSDX fails
I'm looking for feedback on any fails you have experienced with the truSDX assembled by AliExpress. Mine freezes when keying, sometimes displaying "!!Check PTT/key", sometimes the screen flips, sometimes the screen displays garbage, sometimes it turns off and on. It only happens when keying and only when practice mode is off. I complained so they sent me a new one, and it does the same PLUS it often shows 0.00 on power display. Question: Has anyone had a similar experience and what do you do about it? Thanks. Scott NZ4R

Re: AliExpress truSDX fails
What Power supply are you using and how is your Antenna Setup ?
Since the (tr)uSDX is a very simple rig, it does not handle RF injection well, or Power Supply with a lot of ripple....
Bad SWR would cause effects like that, Nearby Magloops, Common mode currents on your antenna line etc.
If I were you, I would find someone nearby with another (tr)uSDX that works for him, and put his rig into your enviroment and vice versa, so you can exclude some variables.

Re: AliExpress truSDX fails
Thanks Manuel. It first happened to me when it was brand new and I took it on a portable op, using Bioenno 12v 3ah 1203AB and portable vertical (QRPguys 3bander). Then I brought it home and put on a dummy load. Same thing happened within minutes. Then replacement unit came, and I put it on the dummy load/Bioenno battery. Same thing. After getting your reply I put it on my Jetstream power supply. Same thing happens. Since it happens to both my original and replacement unit I concluded the problem is either me or AliExpress. I can't think of anything I am doing wrong. Thanks for your advice Manuel. Scott NZ4R

Re: AliExpress truSDX fails
Would you mind telling us the seller and date of purchase ?
I would suggest to re-upload firmware. Try Beta. Maybe something has gone wrong there
In deed: what you describe should not happen.
Let's see how we can fix it.

Re: AliExpress truSDX fails
Thanks again Manuel. I ordered it on 8/27/22. I put it to its first use on a portable op (SOTA) on 9/11/22. This is when it first glitched. ... Please direct me to a post or resource that will tell me how to re-upload the firmware. Thanks again,
Scott NZ4R

Re: AliExpress truSDX fails
The serial # does not appear on my screen, and I am not equipped to upload the bootloader as I read about it. So I went straight to the upload and it didn't work. See attached. I know this is a lot of trouble for you and I am prepared to abandon the project if need be. I am grateful for you help.

If you are interested, reply me, thank you

Read this:
viewtopic.php?t=593
And check your COM port and maybe use another (shorter) USB cable. Not all USB cables work the same.
Did you load the USB-Drivers?

Thanks Matt. I tried the 18 x 0 serial number and the shorter usb cable. But it didn't work. Please see pictures. Notice the Device Manager does not show the right port info. Thanks very much. Scott

Re: AliExpress truSDX fails
Scott,
I have a (tr)uSDX I recently received as a kit from AliExpress, and it seems to perform as expected. I took it on its first SOTA activation today.
I will have mine at the W4 SOTA camp out if you will be attending.

Re: AliExpress truSDX fails
Matt and Manuel, the USB Driver, when I download it, does not show up in my Device Manager. If you would give me an assist on how to correct this I might be able to upload the firmware. See attached. Thanks again.

Re: AliExpress truSDX fails
Does Windows give you a sound, when Connect your USB Cable to (tr)uSDX and Computer ?
If not: It´s not a Data Cable. Use a Data Cable. There are also "Charging Cables".
If it does give you a sound, then you should see the com port or at least an "unknown device" in the device manager.
With device Manager opened: Does Com 1 appear when pugging (tr)uSDX in ? Does it disappear, when disconnecting it ? If that´s the case: Your message indicates, it´s not installing the driver, but using a pre-installed one. Then "right click" the com port, and change the driver. The only driver, that works reliably is the one linked on my page !
This can be everything and nothing.... Hard to diagnose if not sitting directly in front of the PC....
