Hi Y'all,

I have an issue with my 13 month old QDX. It just recently started doing it without me knowingly causing it. It is showing a bunch of vertical lines, 62.5 hz apart on the waterfall. There are stronger lines every 500 hz, but weaker ones at 62.5 hz the whole span of the waterfall. This is on all bands.

The sweeps all look normal and the rig still functions in Rx and Tx, but of course not as well as it should on Rx.

The screenshot below is with the dummy load connected after removing the antenna.

Best I can tell, it's not the environment being picked up since my low band QDX does not show any of this when hooked up to the same connections and band.

I have no idea where to go from here.?

Any and all suggestions and ideas gratefully welcomed.
