Hi Kim -
Oh - that there were a way to do so - its something I suspect like 5.33 or
5.66 hz - has to do with the sub receiver synthesizer mathematics . They are
locked to the same TCXO but don't come out dead on like a truely phase
locked pair of synthesizers. I talked to someone at TT a couple years ago
about it and he thought it had to do with math precision.(probably did not
want to d more computer load ) I have toyed with generating my own 3 rd lo
at 14.xxxxx hz for the sub rx to get rid of that offset - would not be truly
phase locked but I would expect it to stay pretty close for awhile.
Would have already done it if the 3rd LO to the sub rx was a plug in coax
but its not and I hate to cobble on it.
BTW you can get closer by running the other vfo on the sub rx at 1 hz steps
and get the roll down to a part of a hz.
Maybe O III ???
