In a attempt to decode the sstv? signals, I managed to crash SAT 32. I now
have everything working again but have missed the window for ISS SSTV.My
station is SAT32PC with ERC rotor tracking. FT817 radio 1? as downlink? and
IC7100 as radio 2 uplink.I downloaded MMSSTV but could not decode the SSTV
signal. I realized that there was no audio link to mmsstv. That's when SAT
32 crashed I had tried to change to configuration 2. I was unaware that
there was a corrupted file in the software.
What I am confused about is what sstv software should I use for ISS and how
should it be configured to allow sat32 to do its job? and decode the signal
without conflicts?

Hi Jim,
The best software is probably MMSSTV
(http://hamsoft.ca/pages/mmsstv.php). Just run it in automatic mode,
and it should figure out the mode of the picture being received.
What you might do is listen in on 20 meters to the SSTV "Watering hole",
14.230. It's not been very active recently, but that's at least partly
a matter of propagation. The FT817 should be fine for receive, and you
can check out the audio path with that.
Good luck!

Does anyone in the group know of a person or shop that does SMT PCBs from
Gerber files through populating and soldering components.
This is an open source project. The boards are 4? x 4?. Quantities are
small.
If so, please contact: occamrazr yahoo com

Hello
I am working on getting FoxTelem working
I am able to decode packets from recordings in the manual
http://amsat.us/FoxTelem/recordings/
I am not able to decode packets from recording at
https://www.amsat.org/ao-92-commissioned-open-for-amateur-use/
I am not able to decode packets from my SDRconsole V3
Any help guidance would be appreciated
I think my first step is, should i be able to decode packets from the
commissioning recording?
Thanks in advance

That kind of looks like one low current point with a lot of space when
there was no telemetry. Could have been just that the reading was taken
before the Tx turned on for a beacon in idle mode.
Fading could be due to the satellite just rotating such that the antenna is
pointing right at you (or right away from you) or something like that. At
least that's what the Technician test (that I've been teaching and VEing)
says :-)

I forgot about the PL tone frequency. The filter on that is not all that
sharp, and the detection DSP code was improved for at least AO-91 (can't
remember without checking if AO-92 and Cliff got that fix too).
But yes, if the bird does not receive you strong enough it will not hear
the tone either and will not switch on. That said, there is a lot of
traffic on it in the northeast US. The number of telemetry frames I get is
kind of proportional to how busy it is, and 85 is the one I get the most
from. I see you are in IN. You might try passes when it is east of you
and thus within range of more stations along the Atlantic coast.

I've seen the fading cycle up and down in time consistently through at
least a large part of a pass before with AO-85 and I'm pretty sure that's
what it was.

Hi!
I will have an AMSAT booth at the Oro Valley Amateur Radio Club's annual
hamfest on Saturday, 10 November 2018 (the weekend after the AMSAT
Symposium), in Marana, Arizona. The hamfest will be at the Marana Middle
School, along the east I-10 frontage road southeast of exit 236, and
approximately 25 miles northwest of downtown Tucson. Information about the
hamfest is available in a PDF flyer:
https://www.tucsonhamradio.org/images/2018%20Oro%20Valley%20Hamfest.pdf
or from the club's web site:
https://www.tucsonhamradio.org/
Along with the AMSAT booth, look for demonstrations of satellite operating
from the hamfest. I will use my own WD9EWK call sign for the demonstrations.
If you hear WD9EWK on a pass, please feel free to call and be a part of the
demonstrations. The hamfest is in grid DM42jk, in Arizona's Pima County.
I will use my @?????? Twitter account to post updates from the hamfest,
along with pictures. If you don't use Twitter, you can see these updates
in a web browser at:
http://twitter.com/WD9EWK
Any QSOs made with WD9EWK during the hamfest will be uploaded to Logbook
of the World after the hamfest. If you would like to receive a QSL card for
a QSO during a demonstration, please e-mail me after the hamfest with the
QSO details. If you are in my log, I'll be happy to mail a card your way.
73!

Hi,
I've been trying to make APRS (AFSK 1k2 bps) contacts through NO-84
Satellite, and have been unsuccessful in all attempts using UISS and
SOUNDMODEM.
UISS configured with CQ & ARISS.
Incoming packets from satellite decoding perfectly 100% but when I TX,
satellite ignore me :( .
I've monitored the outgoing audio and adjusted the TX level, with no
results.
Also I've monitored the outgoing audio and i heard a little audio tone
difference between AGWPE and SOUNDMODEM.
I tried also with terrestrial APRS digi and it work 80% good using
SOUNDMODEM and 100% using AGWPE.
Of course everything works perfectly using a hardware TNC.
I'm coming to the conclusion that this must be a problem with my SOUNDMODEM
settings, because if i use AGWPE, all work fine and NO-84 repeat my packet
100%, without changing anything on the transmitter (TS2000).
Similar results through ISS APRS digi, (a little better)
I would like to know if someone use a similar setup with good results.

Another person had a similar problem with SDRConsole pretty recently.
Nearly always with troubles decoding audio there is a high pass filter
somewhere that blocks the really low frequency audio (below 200Hz) that
carries the data. In the case of SDRConsole, as I recall there was a
checkbox in some non-obvious place. You might try looking back in the
archived of this BB for the last couple of months.
I just listened to the commissioning audio. I can hear the telemetry but
not very strongly. It seems logical that since this is really meant for
audio, not telemetry, that it was probably recorded in such a way that you
would not get the telemetry. (For example you are very unlikely to get
telemetry recording off the headphone jack of your radio).
Good luck and 73,
Burns WB1FJ
