Hi Jean-Marc,
Very good point.
Actually if you use a Pluto you can use it also with a software based free
solution to receive the WB Transponder without additional cost.
To receive the WB Transponder I prefer the Minitiouner kits from REF or BATC
for about 100 Euros which is still a very cost effective solution.
Kind regards

Dear All,
Forgot to say a major positive about QO-100 which is the cost of setting up
a Ground Station for narrow the band transponder, assuming that the PC is
already available and that one use a Tx/Rx such as the Pluto or Lime SDR,s a
few Chinese WiFi booster, a PLL LNB and a 80cm dish, the total cost is less
than US$ 400.
This is really attractive to students and for all Ham?s with modest means
compared with buying any commercially available transceiver (or may be 2
actually) for satellite operations, thus cost of entry in QO-100 is really
affordable to newbies, more these guys may immediately jump in real Dx QSO?s
and learn the trade, this surely motivate them for further experimentation.
Particularly in remote Islands like us in that part of the globe.
My 1 cent additional input to the subject.

Howdy Gang.
Putting my meager satellite station back up and need an SSB-Electronic SP200
preamp.
Unit must be in very good condition and working FB.
Photos and phone number required, as I was just scammed by seller about this
preamp.
Many thanks for any assistance.

For setting the uplink and downlink frequencies in doppler.sqf, do I set it
to one of the many frequencies starting with the AOS and the software will
adjust from there?
For example, using ke0pbr frequency cheat sheet for XW-2F, if I wanted to
stay approx center, in Doppler.SQF, I would set the file to 435330.0 for
uplink LSB and downlink I would set it to 145990.0
If on another pass I wanted to start somewhere else, I could set it to
435340.0 and 145980.0.
In example 1, the software would adjust from 435330.0 to 435350.0 as the
satellite passes over me. (AOS to LOS).

Burns,
First of all, no apology is necessary. Had I actually thought it would be
as easy as a hidden ./FoxTelem folder in my user root directory, I wouldn't
have asked. I found the setup files and removed them, and then just
attempted to launch FoxTelem as usual and it went through the normal setup
stuff that I was expecting.
The original location for the logfiles was in a older version of FoxTelem's
run folder - which I had deleted. So now I've created a special logfile
folder which will never get thrown out (like the baby with the bathwater).
This was not a "Fox-in-a-Box" install, only because I've been running this
pi for a few years and I don't want to add all the other junk that's on
it. So the current install was downloaded directly from
http://amsat.us/FoxTelem/Linux/.
Thanks for the help, and I apologize for not digging a little further (I
had actually checked a bunch of the system config folders for just such a
folder - I guess I dug too deep without scratching the surface first).

And you move around the passband with your VFO, you don't change the .sqf

I?m in a unique situation with 1 cat controllable radio (817) and another
that can?t be CAT controlled. Maybe this is non standard. I think it is
probably equivalent to using a SDR for receive and a 817 for TX. I don?t
think I can leverage the power of tuning around and the software adjusting
for me. I will stay parked in the center

Just to clarify a bit more, the value in the doppler.sqf file is the
frequency that the satellite will be receiving or sending. So when you
look up the satellite and it says the passband is from x to y, then you put
it in the middle of this range. Ignore doppler and let the software do it
for you, at least on the radio that you can do CAT with.

You don't need to stay parked in the center. Most people who don't use cat
control or operate half duplex come up with an offset that is NOT in the
center of the passband, but off to the side. Staying parked off to the side
is less of a problem for everyone else trying to use the bird...

I?m in a unique situation with 1 cat controllable radio (817) and another
that can?t be CAT controlled. Maybe this is non standard. I think it is
probably equivalent to using a SDR for receive and a 817 for TX. I don?t
think I can leverage the power of tuning around and the software adjusting
for me. I will stay parked in the center
