Try http://amsat.org.ar/pass.exe then start HDSDR.
Set HDSDR with Options DDE to SDR and select Orbitron.
Should work even with generic SDRs.

Content-Type: text/plain; charset=utf-8; format=flowed
Dear Folks:
I have been able to get my computer and the Yaesu FT-736R to play nicely
together, and indeed, have had several QSO's with the frequency
compensated for by the computer quite nicely (on both AO-7 and FO-29).?
But, I have now run into a problem.
A few days ago, I was trying to hear myself on the downlink for FO-29.?
I couldn't hear myself, and started adjusting the frequency controls on
SatPC32 to try to find myself on the downlink.? I was completely unable
to do it.? Then, I noticed that whenever I turned on the CAT control on
the software (the "C+" toggle), the receive frequency was jumping out of
band (explains why I couldn't hear myself).? I looked on SatPC32, and it
was showing an out-of-band frequency for the downlink.
I have since tried all sorts of things to get that downlink frequency
back into the band and can't figure out how to do it. And, tonight,
during an FO-29 pass, I noticed that I could only change the uplink
frequency but the downlink frequency was stuck where it was (it was in
the middle of the downlink passband) and it wasn't being adjusted by the
computer at all.? So, I suspect I've completely hosed up the CAT parameters.
Can anyone send me an email (hamdan@xx.xxxxxx.xxxx and walk me through
the process of getting SatPC32 properly working for CAT purposes?? Like
I said, the hardware is working fine.? It's the software.? It's also the
sysop. :-(
I appreciate any help you can give me.

Hello David!
From time to time with the FCDPP I find this helpful to do if something is
going "wrong":
exit FoxTLM
unplug/plug in FCDPP
followed by launching FCHID2.002.exe then resetting to default values, then
setting the frequency to the "center" frequency I want to use with FoxTLM
followed by launching FoxTLM
That fixes about anything "weird" I've seen!? Give that a go.

Yea "L-band Downshifter"! Something to schedule during Experimenter's

If all of the parameters are greyed out, including LNA and Mixer Gain, then
something else has opened the connection to the Dongle and FoxTelem can't
read the parameters or set them. FoxTelem will still read the audio from
the dongle because it is a different interface. This allows you to have
multiple programs all reading from the same dongle, but only one can open
the connection and control it.
If LNA/Mixer gain are not greyed out and the filter is set to an odd value,
then something in the dongle has gone funny, as Mark said. Un-plug and
re-plug should be enough, but his more extensive procedure should surely
work.

HI all,
Thanks Mike, really helpful.
It seems that the MFJ is about 10 dB better regarding UHF rejection on the
VHF port according to your measurements, which would help battling desense.
It seems the absolute minimum of about -70 dB is around 380 MHz though, so
a bit of tuning might make it even better.
73,

Hello Nitin,
I use 145930 for center frequency in FoxTLM.

From time to time with the FCDPP I find this helpful to do if something is
going "wrong": exit FoxTLM unplug/plug in FCDPP followed by launching
FCHID2.002.exe then resetting to default values, then setting the frequency
to the "center" frequency I want to use with FoxTLM followed by launching
FoxTLM That fixes about anything "weird" I've seen!? Give that a go. Mark

Yono,
I just looked at some web pages that are captureing YB0X packets and I do
not see any digipeated packets? Is this because the digi is off, or there
have not been any recent users? Or the web pages are not looking for
YBOX-1* etc?
For example SATWATCH: http://59.167.159.165/
And this one:

Or am I looking in the wrong place?
Thanks

Bob ,
The callsign: YB0X-1
Alias: YBSAT
Callsign substitution on alias
The hardware is Tracker2
I believe I emailed you in 2011 when the payload was complete and waiting
for launch opportunity.
Note: I can add APRSAT as another alias.

I tried to use preliminary data for FOX-1D from
https://www.amsat.org/getting-ready-for-fox-1d/ , by N8MH, but my
GPredict refused them ( new satellites = 0 ) .
So I wrote small program for check and repair of TLE data.
Here they are:
preFox-1D

Hi Bob,
It is digipeating,I tried a couple of days back but there is a schedule for
activation of ?the various payloads and is published on the amsat ID
facebook account.I am not sure if there is place like ariss.net or
pcsat.findu.com for Lapan A2 where the satgate data is captured.?73
