I must say that I find it interesting that we have not heard back from the
original poster
concerning this subject. You would think he would provide some response after
all the comments that have been generated by this topic.
Perhaps the subject matter became way too involved for what was needed

Hi Rex,
that's a lot of great information! S
Hi Said and All
I have been following this thread with a lot of interest because my
application is also in portable Microwave operations with narrowband modes
such as WSJT. The main issue here is not so much long term frequency
stability as one only has to find a signal in an SSB passband, but th

As a ham, I've got a vehicle with a bunch of batteries and they charge
off of my engine, but let's be practical. I'd rather spend my battery's
energy on long term receiving and on transmitting significant power than
on

Hello to all,
I think everyone is missing the boat here, so to speak. Eric does not
necessarily need a high degree of accuracy.
What he really needs is stability. So if he was off frequency a bit, that could
be handled in the tunable IF unit, which is, most likely, some wide range modern
