Hello Ken
Have same issue.
Could detect LO signal (RX -12kHz,-40dBm) and additional sidebands at 6 m and 10 m at BNC (RX).see also my Posts. Another OM also detected these Signals.
Resoldering trifilar sidebands at 6m and 10 m have gone, but weak 1500Hz Tone remains(-120dBm)
Noise floor reduces from 25 dB to 6dB @6m.
@12m Noise floor and digital signals enlarge. But QSO is possible.
Can you verify sidebands @6m and 10m?
I try to document my measurents and suggestions.
