Hi Chuck,
essentially, what you are saying/seeing is: two UI boards in combination with two different RF boards show the same problem. 1. The problem could be in the schematics (unlikely), but in this case others should be able reproduce this. 2. It could be in the software in general, (unlikely), but in this case others should be able reproduce this. 3. It could be in the software in combination with some settings, in this case others should be able reproduce this if they have the same settings.
So for now number 3 is more likely than the other scenarios (apart from some broken / wrong components on the boards) and more easily reproducable, please download and send the settings here or in a Github issue, please use the backup tool, see here https://github.com/df8oe/UHSDR/wiki/Backup-and-Restore#backup--restore-on-external-computer-since-2919.

I just found out that this problem started with 2.9.16 firmware.
I loaded 2.9.15 and all is well.
THERE IS A FIRMWARE ISSUE!

OK, I reset the EEprom, I set to defaults, I loaded 2.9.43, and all seems to be working OK now!!!
Both radios are OK right now. I will do calibration on both and see what happens.
Thanks, so Far!
73, Chuck

All seems OK now that I have cleared the EEprom and reset to defaults, loaded new firmware 2.9.43, and calibrated. Very confusing, but there must have been something that corrupted the info. Maybe I should do the EEprom reset before doing anything the next time!!
Thanks for putting up with me.
Very 73, Chuck WD8BXS

Hello Friends,
This is excactly what I encountered recently. I first thought it was a xslate problem, but it was exactly as Chuck described (see the Rx IQ auto correction problem topic in UHSDR Firmware). Downgrading the firmware also did the trick, but not the same versions.
The problem solved after a full reset and I unfortunately lost my settings in the process, but I have two more TRX with the problem (one mchf, one OVI/mchf RF).
Before performing reset, I will do some measurements with RF generator and this time salvage the settings file.
As soon as the QRM pro slow down a little...
Best Regards,
François

Hi Andreas,
This is the config file from a v0.6 mchf (cpu 413h, BL4.0.0, FW 2.9.46) which exhibits the problem discussed here.
I will post another config file from an OVI40 soon. Sorry, I forgot, I had reseted this unit last week...
Hope this will help to pinpoint this unexpected behaviour.

Hi Andreas,
Yes, this is a tricky problem. I will freeze this mchf until we fix it. So don't hesitate to ask me for any testing.
If necessary, I might sent it to Germany too, not complicated.
Best Regards,
François

Hi Andreas,
As promised, please find attached a second Config File from another mchf with the same signal ghosts. I hope this will help to pinpoint the troublemaker.

Just did a radio, that had the 12khz problem, reset and problem went away. Went through the calibrate and now the issue is back.
Here is the config file for you to look at.
