Hello all, I notice that on K2 #03547 rev B (with KPA100, KDSP2, KSB2, K160RX and thermistor installed at time of build) the master frequency drifts as a function of temperature. From an ambient temp of 65F to max rig temp when the KPA100 fan kicks in the receiver may drift by 800 Hz. The range is usually more narrow given the typical temp shift experienced.
My solution has been to calibrate C22 against WWV such that as the rig warms up, the master frequency set by C22 drifts towards zero-beat with WWV. My question is this: how much drift is typical?
