For what it's worth, I think I prefer the manual doppler correction on
the highest frequency, which can be done manually.
Full doppler essentially requires constant computer control of both tx &
rx frequencies, AND a whole lot of accurate data.
I've had similar experiences at Field Day, an
I am new to the linear birds and am having the same problem, Tom. It seems
to be kind of a "D*(%#@ if you do and D*(%#@ if you don't" type of thing
with computer doppler control. I have a FT-897 that I have used half-duplex
with CAT control via SATPC32. I have also tried full-duplex using my TH-
Tom,
There was an article in the Journal a few issues back on why the various
manual techniques are only approximations, sometimes surprisingly bad ones.
I think the author's call was WA4SCA. So it does get talked about. With an
accurate clock, and current Keps it is possible to work a full pass

No!
If you have it at your station, great! Take advantage of it,
but remember that not everyone will have the same setup
as you.

Tom,
I tried full doppler control with HRD's sat tracking software and wasn't really
thrilled to say the least. I may again try
Macdoppler as it's so far the best sat program I've seen but my main shack
machine unfortunately is a Windows box
because HRD's logging software is more convenient th
Hi Alan!
I wanted to make a couple of points regarding some of your comments
from your earlier post...

One of the things I like most about MacDoppler is that I can turn the VFO and
it will follow me. It does not enforce that I use the program to change
frequencies. That allows one to use a simple VFO know interface to change
frequencies while still having full Doppler correction.
I have tried ev
