[Elecraft] KX3 Temp. Cal. Routine Issue Revisited

[rick jones]

So I'm having the same problem as I've read in a few past posts (with no resolution). At Approx. 40DegC I lose the signal in the speaker, the S meter reads no signal, and the F value starts to wildly swing in the 700 range. I'm directing my hot air at the heatsink for what that's worth. I had it increasing at about 1degC per 1-2 minutes as instructed. I can't imagine the procedure is still going ok given those symptoms but maybe it is. Any thoughts? Thanks.
