Of course, we all know that the importance of having precise "time" is
(pun intended) relative; but accurate time also gives us accurate
frequency measurement.

However, I'm drawing a blank when I try to figure out how to adjust the
transceiver I use so that I can work the automatic packet stations on
the low bands.

I have, of course, a crystal calibrator, and I tune in WWV and zero-beat
the calibrator, and sometimes I even remember to turn on the BFO for a
little extra precision.

But, when I'm trying to figure out where to set the rig so that I can
get through to an automatic packet station, I /never/ get a response.

So, the question, or probably several questions, is/are "How do I get
from the NBS clock to a reliable dial setting on my rig"?

Thanks for your time.

Some modern Radios use a 10 or 20 Mhz Master Osc. in the PhaseLocked
Loop... so what you can do, id use the 10 or 20 Mhz Master Clock output
from one of the GPS Receivers, that have that output, to replace the
Master Osc. Input in your radio.... Kenwood had an Option to do just
that in the TS-950 Radios, and it isn't that hard to HomeBrew up
something t do that.... Just Say'en.....
