Re: [IRCA] Offsets
I'm sure that mwlist would also like more input from the smaller
stations Aaron.
I have done this before, using an audio scheme that I think is
something like you describe. 0.1Hz resolution is more than possible,
but as you point out, accuracy may not be as good. I've been saying
+/- 0.2Hz, but I think it can be better than that.
One other problem is calibrating against stations of known accuracy
with low drift. KSL-1160 still seems to be pretty good out west,
but IBOC stations don't seem to be as reliable as they once were.
At any rate, I am interested, just not sure how much time I can
devote to it at least until next spring.
best wishes,
Nick

Is anyone interested in doing a better job of collecting offsets for
North American stations? I know mwlist has some, but they only have
the big US stations. I think European DXers are making most of the
contributions.
I recently figured out how to get 0.1 hz resolution on my QS1R
(using HDSDR, tuning below the carrier, and using the audio spectrum).
I'm looking at 1280 now and I see what I think are 30+ carriers!
Very exciting!
While 0.1 hz accuracy might be hard to achieve (even if your own
receiver can do it - the transmitter won't necessarily be that
stable), we should at least be able to do 1 hz.
