Re: [Elecraft] [K1] VFO Drift Problem

applying the same exposure to the normal K1, then you can draw better conclusions. 73, Don W3FPR On 5/5/2011 11:52 AM, Matt Scholz wrote: Thanks Don. So here's another question. My first step was to remove C2, which effectively removes the varactor (D3) from the equation. I was still

[Elecraft] [K1] VFO Drift Problem

Hi - I am trying to reduce my K1's VFO drift to an acceptable level. The VFO frequency drifts up at a rate of about 30Hz/minute (after a 5 minute warm up). Even after one hour, the drift is still about 15Hz/minute. This is too much, obviously. I have been trouble shooting this with the help of
