If it runs at startup but fails during/after transmit than it is probably RFI.
Here are some potential solutions -- ordered by cost.
#1 Free - Move USB cables to another port -- some ports are more susceptible
than others.#2 Free -- Check your grounding system. rod-outside-the-shack is a
common problem when it's not bonded to the main house ground.
http://www.k9yc.com/GroundingAndAudio.pdf #3 Add some USB shield isolators (see
my QRZ page).#4 Good USB cables like
thishttps://www.amazon.ca/Tripp-U023-006-Device-Ferrite-Chokes/dp/B003MQ29B2/ref=sr_1_5?crid=11YRNPWDVWGCU&keywords=usb+cable+with+choke&qid=1658187349&sprefix=usb+cable+with+choke%2Caps%2C139&sr=8-5
#5 Maybe free (if you have chokes...otherwise can get a bit costly) -- add
chokes to USB cables first, then all other cables including power, ethernet,
and control cables.
Fair-Rite torroids are good quality -- do NOT buy cheap Chinese ones --
https://www.fair-rite.com/product/toroids-5943003801/ You can use clip-ons but
torroids allow multiple wraps and give better
results.https://www.fair-rite.com/product/round-cable-snap-its-431176451/
I couldn't find type 31 torroids at Fair-Rite as of 20220721 but Palomar has
some
