I have found in my neck of the woods I use 145.830 on pcsat and have
better success decoding. Have better probabilities with very short coax
runs and 1/4 wave.
a couple packets in for each pass is goodfor the designed purpose. Am
presently using the kenwoodD7 with the stock duckie but compare it to
signal strength with my other handheld on a 1/4 wave mag mount....the
mag mount is way more sensitive! but have to get a sma to bnc connector
for the d7.

Yeah, I thought about that and tried 5 kc up on the scanner with no luck. I
didn't have predict running at the time, but as I've been watching passes
since then it looks like the doppler shift usually starts out around +2200
hz. My FT-209R isn't exactly the best thing for tracking a changing doppler
shift - to tune in 5 kc increments, you've got to find a sharp implement to
push the '+5' button with, and that's the finest tuning it'll do.
What increments do good satellite base stations tune in? I would assume
it's a lot less critical on FM than SSB - it's just attenuating the signal
and not shifting tones, right?
BTW, I've found 'predict' for UNIX to be a great tool for tracking up to 24
birds at a time. It's got rotor controller support, and the price is right.
AGI's Satellite Toolkit is still my favorite package, though. I think the
base program is free, but the nifty add-ons for stuff like 3D imaging will
set you back a few grand. Still, it's WAY beyond any of the freeware or
shareware packages I've used.

5 kc is no good.. Closer to 1 kc or two at the most. What is being
affected is the frequency, not the tones. You want a quieting signal and
the tones take care of themselves, :-)

Here is the "answer" about the process formerly known as type acceptance
and its application to ham gear.

No, just amps.

Hi,
Glad I could help.
A question. I know it is no longer known as type acceptance anymore.
However, is there any other ham gear, other than "certain external RF
amplifiers" that under go the same type testin' by the FCC?
I am aware of the Part 15 certification for receivers of all types, ham or
not. Also, the spectural purity requirements.

..83 instead of .85? Might have to try that and see what I can do.
Thanks Kevin!

No...he meant .830 instead of .825....not .850
I assume that was a typo, but let's not get anybody completely confused.
Early in an approaching pass I have found nearly 830 is better for
quieting...and of course you have dial error problems as well. One of my
radios is about 1.5 khz off at 2m. Once you find the true "center" freq, you
really should be ok for 95% of the pass, without having to move your rx
freq.
