[Elecraft] [K2] Long term reliability with leaving radio on 24/7???

[Geoffrey Mackenzie-Kennedy]

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,
