[1000mp] Slight Drift

Sun, 10 Mar 2002 23:33:49 -0400

Thanks Andrew, good point, his has the standard TCXO, but this has just
started with his rig....now if we can just find how to calibrate it....I may
have to watch the TCXO in my Mark V the next time he's in my shack.

Stu,

Is this really a fault or just normal warm-up behaviour?

Yaesu spec the standard TCXO (is it temp controlled?) at +/-10ppm so if
this is happening above 5MHz the radio is within spec!!
