Mike,

My K2/100 stayed put without any issues while running 24/7 in receive mode
for almost two years, while monitoring for any 2 metre openings across the
pond. I did disable the transmitter to avoid accidental frying of the 2
metre converter.

In normal use on 40m, it drifts about 10 Hz during the first few minutes
after a cold start before settling.

73,
