[Lowfer] TAG copied Jan 20 and 21

[John Andrews]

Neil,

Nice reports! TAG's frequency is based on a 10 MHz surplus Vectron 
oscillator module that has a proportional oven. Picked it up for $50 at 
a flea market a few years ago. Since the TAG exciter is in an unheated 
building, that oven control is a big help. My setup at home isn't too 
well calibrated right now, but TAG seems to be staying within 0.02 Hz of 
185.000 kHz. I get some temperature swings in the cellar at home this 
time of year, and the Icom R75 that monitors TAG does wander a bit.

Anyway, thanks for the reports.
