On the U/v linear and FM satellites, there?s not really a need to do any
correction on the downlink. For the V/u there is definitely a need to
correct for Doppler. I know of several people that use a SDR as a downlink
radio on U/v satellites. Best of luck!

I answered you when you asked this on January 29th, but will provide more
detail as to why this isn't possible without quite a bit of effort.
The Raspberry Pi uses an ARM-based processor, generally running some
distribution of Linux. SatPC32 is written for computers using x86-based
processors running Windows. There is a possibility you could get it
running, slowly, with a lot of effort through use of x86 emulation and the
Wine compatibility layer, but it would require quite a bit of rather
advanced work.
Gpredict is the software you want to use for satellite tracking and it
works great on the Raspberry Pi. Unfortunately it's not in the Raspbian
repository, so it does require some work to get it installed. Without
knowing what operating system or what version of the Raspberry Pi you are
using, I can't direct you to the proper guide.

You could install Ubuntu instead of Raspian, I guess. Gpredict is in the
repositories.
At any rate: GIYF.

P.S. I always think it is funny that people want something cheap, small
and lean like an RPi and still expect something like the whole clunky
Windows system with its software to work on it. The RPi was designed
with the maker/educator in mind and that almost automatically means
using a Linux based distro.
So please, if you want to start tinkering with RPis or other single
board computers (SBCs) then start changing your thinking and that means
no more Windows. If you don't want to change, then don't consider low
cost SBCs an option.

James,
Look into up-board.org, should suite you better than a RPi. It's not cheap
but it's not expensive either, considering what you're getting for the
size...

Hi Bob,
I have this setup. It works great--and in fact so well, it's hard to see!
The "setup" didn't do anything for me unless I ran the numbers WAY off to
one side or another. Then the radio acted weird--it was effectively messing
up the proper oscillator freq. and sounded warbled. I've put coarse and
fine in the middle of the recommended ranges and leave them there...the
"tuning" is broad. Don't fret over adjusting uch here...
How can you see it working? Here's what I did--use the waterfall to watch a
stable, steady signal (even a "Birdy") on 2M, on SSB. Zoom in the
waterfall, so it's like +/- 2 kHz. Now, using the software for the freq.
standard, toggle the reference signal ON and OFF, slowly....you should be
able to see the "birdy" move just a little, back and forth as you toggle off
and on. With the freq. standard "on", it's in the right calibrated place.
With it OFF, it's showing you how far off freq. your radio is without
correction.
Hope that's clear! I spent some time convincing myself it was working--and
did what I tried to explain above. check it out, let me know how you make
out.
73,
Mark N8MH

Gpredict is very easy to install on a Raspberry Pi. I did so on the
"Buster" version of Raspbian. There is a .deb file to download and it just
installs and runs. Disclaimer: I have not tried to use it more than just
to see that it started up ok and displayed satellites.

1. Is this the best way or place to post such questions?
2. I have studied past posts and other sources but can't find answers to
questions below.
3. I am trying to listen to ISS. N2Y0 and HeavensAbove list the same pass
for my location today (FM14be, 16:39 local time, elevation 56 degrees) but
AMSAT predictor says 4 degrees for that pass. Why the difference?
4. N2Y0 says up/down is 437.550/437.550, ASFK, inactive. HeavensAbove says
145.825/447.550 FM
active. Who is right? How can I get correct frequencies to listen to?
thanks

Latest list of frequencies posted at:
https://www.amsat.org/amateur-radio-on-the-iss/
The 145.825 MHz packet is most common operating mode. It has its on/off
days depending on crew activity and radio health.
Watch the amsat-bb for ARISS school contact announcements. For example
there is a school contact scheduled for next week - direct with a school
in Ohio. The 145.800 MHz downlink will be good copy over a lot of the
northeast and parts of the midwest.
> Why the [time] difference?
Often related to differences in using local time and UTC on different
sites. I'd go with the amsat predictor for now.
