I've been trying to decode the 1.2k BPSK telemetry from MYSAT-1 (44045)
without success. I'm using UZ7HO's SoundModem set for BPSK AX.25 1200 bd.
The SDR is set to USB with 4 KHz bandwidth and the signal is strong with a
25 dB SNR. The received signal is right in the center of the soundmodem's
waterfall between the upper and lower indexes for that BPSK mode. I'm
obviously missing something here!

I am wondering if, as a Sat. decays, getting closer to Earth, will there be
"better" comms ?
Guess they will be moving faster. Will the Keps "decay"? Interference
from "reentry" heating ? Battery's gone first ? Solar panels "ripped" off.
Or, Just GONE ! Orbital mechanics at it best.
Wondering what the "mechanics" of re-entry are. Can't be "pretty". Poor
little satellites. So many people, worked SO hard to get them there.
Just curious.

They speed up as they re-enter and it is all over in a single orbit or so.
Lots of hams captured the re-entry of the APRS RAFT satellite and you can
see it warming over the last few days and then rapid rise in the last 12
hours or so:
http://aprs.org/craft/save-raft.html
It was still working up to 2 hours before re-entry. Might have even been
closer, but we may not have had someone in range of it on its last
bleep...

Hi Ken!
Things certainly sound right from your description, but just for comparison
sake here's an image of a MYSAT-1 packet as I was decoding from a recording
some time ago:
https://www.qsl.net/k/k4kdr//images/mysat-1--iq-replay.png
... you might also want to check the "Modem Setttings" in UZ7HO SoundModem
and make sure that "non-AX25 filter" is NOT checked. FYI, I normally leave
"KISS Optimization" checked and "PreEmphasis filter" with "All" checked.

I can tell you from personal experience as a satellite mentor, giving
presentations which always excite potential new satellite users, then
having them go into the field to experience the bedlam of a FM Satellite,
that they too often become discouraged and give up. Easysat is a very
deceptive name, especially on weekends.

Message-ID: <6CFEF31A3A774D91AEFB691A81AF0979@?????????????>
Content-Type: text/plain; charset="utf-8"
Hi All,
For several months I have been automatically receiving frames from the Fox-1
satellites. Typically at ?3 degrees elev, the az/el sets the antenna
position correctly and the radio is tuned to the correct frequency. But
lately as soon as 0 degrees el is reached, SatPC32 stalls, the clock stops
and nothing further happens until I manually click on the enabled satellite.
Everything again proceeds normally, until the next scheduled satellite
reaches 0 degrees el and SatPC32 stops. Since this error I upgraded from Ver
12.8c to 12.8d which produced the same error. I reinstalled 12.8c but the
condition persists. In receive only mode, I?m using a Flex 1500 with
FlexSatPC 7.2.2 and the computer uses Win10 Pro with an i7 processor and 8GM
RAM. CPU demand always is less than 10%. I?m at a loss as to where to look
to resolve this issue. Any guidance is greatly appreciated.

Ken in addition to what Scott mentioned,
I use a configuration that launches multiple versions of the UZ7HO for
different sats and it has repeatedly decoded MYSAT-1 with the following
config:
I use 6250hz for bandwidth on SDR# and have the BSPK ChA set to 3472 and
Audio slider on SDR# is between 3rd and 4th

Tesla is releasing Field-Day mode (er, "party mode") in its models to
allow the vehicle to continue with AC/Heating, Temperature control,
airflow, selective lights and music for up to 48 hours or more while in
Park. The feature will also allow users to power other electric devices
using the electric car's battery.
When you think about it, the 75 kWh battery in the model 3 or the 60 kWh
of the Chevy Bolt can run the average American home at normal loads for
about 3 days, or a week under power saving conditions. With about $1000
or more of solar panels , you can have transportation and also maintain
that Field Day forever. ;-)
Just sayin...
