[Elecraft] K144XV issues in K3S - audio distortion and fading signals over time

[Grant Youngman]

Have you double checked all of the connections in and out of the 2M module?  I’ve found it’s important to remove the transverter’s top cover to do this — because it is possible when pushing cables into the female connectors blind, even being careful, to actually bend back the business end of the sockets.  I don’t remember off hand which two it is, but I’ve had enough problems with them that I now support them from the rear with a screwdriver blade when seating cables to ensure a solid connection.

Otherwise, it sounds offhand like there’s something bad on the transverter board …
