[Elecraft] K1 Frequency Stability

[Dave]

I've just finished measuring the drift of my K1, serial 1154. Shack ambient
temperature 25 C.

Allowing for a 5 minute warm up, measuring on 21.060 my K1 drifted down by
197 Hz over a 60 minute period. The highest frequency band I have is 21 MHz.

Measured into a dummy load with -40 dB resistive tap, transmitting just long
enough to measure the frequency on a Racal 9916 counter with off air
frequency standard.
