Garry: Thanks for info.....
Most recent capture at 137780.46. Since I started with my call at 499.99
vs 500.00 BFO offset, the net drift between my Isotemp OCXO in the LF
converter and the TCXO in the FT-817 is .02 Hz according to ARGO.
Yeasu only rates the TCXO for .25Hz an hour for the FT-817. Double
regulated power supplies and foam insulation on both the LF converter LO and
FT-817&TCXO helps, but more likely to two oscillators are drifting different
directions and making the result appear better than it is....
