I just finished listening to a SO-50 which I was going to try to work as
K2A if I could get in. I've only worked FM birds a couple of times before
and I remember it being busy but that was just stupid. I'll either try off
hours or stick to linear sats. Not to start something but man I hope we can
get some higher orbit linear satellites again :-(

I heard you at least once, early in the pass. I tried calling you from K2J
as that would be a fun colony to colony contact.

The pass was fairly hectic. Sorry you experienced that. It unfortunately is
not uncommon on FM passes, and yes, that is why some prefer linear sats.

I will say it is not always that bad and sometimes a lot of people will
make a lot of contacts and when it's really orderly it is actually
impressive to hear how so many people can share such a limited resource.

Hi Dave, if we can get the 13 Colonies event back to where it was when we
had a solid 13 colony precipitation on the sats it will become a 'rare grid
level event' on the FM birds. I remember working 24 stations on a single
AO-27 pass from Delaware in 2012 and nobody complained! Hang in there,
better 13 colony things are coming...

PSAT2 has been enabled for Digipeating on 145.825 up/down.

Also the APRS-to-Voice feature is enabled if you send a packet in APRS
message format TO PSAT2-SAY and begin the message with CCCCCC sez speak
this?



Where CCCCCC is your callsign padded to 6 bytes with spaces and you must
spell ?sez?  which is the key word.  What will be spoken is ?CCCCCC sez
speak this ??



But DON?T EVEN THINK about it if you are not tracking Doppler on the
uplink.  You wont get in and will only jam others.  If you radio can only
do 5 KHz steps, then the only time for you to transmit is a few seconds at
max elevation when the Doppler passes through 0 offset (And you are
strongest then anyway).



DO NOT ATTEMPT any DTMF modes.  They are disabled.  They take longer uplink
times and will be quite jamming to others.



ALSO, because of all the APRS calls in space, FINDU.com and I are cleaning
up the links. PCSAT.APRS.ORG will now only capture USER packets and will
not be cluttered with satellite telemetry.  Find telemetry from each
satellite on this top-down page:



http://aprs.org/sats.html



Object number we now think is 44355 or 44354 that are too close to tell.

PSAT2 is doing great!



PSK31 and SSTV transponder  have been on since launch.

SSTV downlinks are looking good.

See Gallery:  http://www.urel.feec.vutbr.cz/esl/psat2/sstv/

Still waiting for first report of user PSK31 contacts.



But I have not said much about the VHF modes? because we have had
difficulty commanding.  This is because the PSAT2 VHF uplink uses an
inexpensive narrowband XCVR module which is intolerant of overdeviated
signals, exactly what you get with +/- 3 kHz of Doppler.



ANYWAY, we can now consistently command if we set the Kenwood to narrowband
NFM and do it right in the middle of the pass.  Plus, we can extend that a
bit  (1.25 KHz after center) by then changing the radio step size to 6.25
Khz where the channel raster ups the channel by 1.25 KHz).



So, we now have command again!  You may have seen that we have turned on
Sun vector S#... telemetry and can easily see by plotting the 1 minute xyz
xyz xyz vector triplets that it is smoothly tumbling at about 1.3 RPM for
nice battery charging and good thermal management.



The downlink is live on FINDU:

http://www.findu.com/cgi-bin/raw.cgi?call=psat2-1&time=1

Background:

This last 6 days of crisis was complicated by the fact that I am operating
in a temporary dungeon while the building is being renovated and all my  27
years of lab stuff is in 200 boxes surrounding me.  I installed a temporary
ground station on the top floor and modest antennas and a TV rotator and
the contractor let me drill a hole through the wall that they can seal up
later.  But the big problem is the 8 flights of stairs from my PC and
internet connectivity  in the dungeon up to the radio 6 times a day for
passes with only a few hours sleep and all kinds of what-if-dead-ends.  And
with passes from 10 PM to 2 AM.



But we are back in the saddle again!



And this good news reprieve is only an hour old, so it will take a while to
decide what we want to do next.  In any case, the Brno University PSK31 and
SSTV transponder has all the power for now, so enjoy.

Uplink USB on 29.4815 and downlink on 435.350 +/- Doppler.  The transponder
only comes up if there is a user in the uplink with PSK31.



Bob, WB4APR

Hi Bob!
Managed to copy my first SSTV image on 17 degree pas @????? UTC today.
Looks like its a image from the ROM of your desk. Also managed to copy a
PSK31 telemetry frame on 375hz: PSAT-2 A bDmk bBaalfvdpqjEar aaaa A bCph
bBamlkujpqjFak . No luck this pass in trying to bring up the PSK31
transponder and seeing my downlink, but this was my first attempt. I will
keep trying on 29.481.50. My SSTV image can be seen on my twitter here:
https://twitter.com/KE8AKW/status/1146238059698110465 . Also looks like two
stations were digipeated in the US on that pass according to FINDU
http://www1.findu.com/cgi-bin/pcsat.cgi?absolute=1 . Thanks for enabling
the digipeater. We cannot wait here in the higher latitudes to finally hear
and work PSAT-2!

Amazing job at only 17?, Nick - congrats!

Also on that pass there was some digi-voice which really caught me
off-guard... not something we're used to on the other APRS sats.

Still low on the horizon so it's not totally clear, but sounds like
"WD4???"   Here's that audio:

Hi All,

I am preparing for a satellite talk and QO100 demo this Monday 8th July
at the Milton Keynes Amateur Radio Society!

I have a slide that shows Oscar 7 as having been launched in 1974 and I
am tempted to state that it is the oldest satellite in earth orbit that
is still functioning! (not just the oldest Oscar) Would I be correct?

I will, of course, explain about how it was "out of service" for some
years in the intervening 45.

many thanks

Graham G3VZV

Graham,

There are a few older satellites that still transmit signals, but I
believe it is the oldest satellite in earth orbit that is still
providing a useful service.

Graham,

My first satellite contact was on AO-7 in 1978, I was 16 at that time. For
sure it is the oldest Oscar still active as my last QSO is only a few months
ago.

As you suggested, it would be interesting to find out if any commercial,
military or commercial satellites have last so long as it may be an Amateur
breakthrough, open question to all.

QO-100 is a fantastic opportunity for us for experimenting, as an example
here in Mauritius LEO?s have very limited coverage we are in the middle of
the Indian Ocean and only FR sometimes and ZS regularly on the air, the bird
has open the opportunity for us to tests many modes as for example ATV which
was inexistant here. I just hope that eventually we will have 2 additional
GEO?s linked so that global QSOs possible on a 24/7 basis, just a dream,
which may become true if we all dream strongly in the same direction.

Best wishes for your demo.

Regards



Jean Marc (3B8DU)

Hi Graham,

If you like, you could mention that AO-7 was commanded successfully for
the first time after it returned on July 11, 2002. The Command sent was
to change the speed of the CW beacon. It worked!!
