Hi Bob,
Congratulations !! on the successful launch of the satellite. I heard strong
signals during the 12:30 UTC pass on June 26th over India. Will turn ON the
satgate tommorow.

Northern Hemisphere passes begin at about 9:35 PM LOCAL time
Then again at around 11:15 PM and then about 01:00 AM local time ish....
What is amazing, is that it looks like it is about the SAME time every day
for a pass even though the orbit is moving earlier
After a few days, there will be a new orbit around 8 PM local time, and
the others above will continue at the same time.
And so forth. So it is moving earlier but appears to have this sun
synchronous behavior...

There is a lot of great activations happening this Summer.? Be sure to keep

In addition AMSAT's call sign, W3ZM, is popping up all over the U.S. in an

Hi Bob,
Thanks for the link -- I had totally missed that before.
How does one register to appear on that database? I'd like to add Rhode

Hi Paul,
Thanks for the interest in the PSK31 transponder, as Bob already pointed
up, the downlink audio spectrum is shared, so at 280Hz and 374Hz are
PSK31 beacon tlm streams from camera board and transponder board
respectively. Then every 4 minutes the SSTV signal is present so if you
plan experiments in PSK transponder, try to stay between the beacons and
SSTV. Description of modes you can find at
https://github.com/alpov/PSAT-2/blob/master/README.md
We would be glad to answer any questions about this experiments.
We are still awaiting for any positive confirmation of downlink signal
at 435.350MHz as for us it is still below horizon. Any audio recordings,
IQ data or at least pictures of reception would be welcomed.

There are a few successful UHF observations at SatNogs. I tried to
decode the SSTV signal, but it was a little bit off frequency, so only got
some somewhat organized "noise" in the picture.

Thank you for the updates!
Regarding the PSK31 uplink, please advise the correct RF frequency.
At http://aprs.org/PSAT2/USER-Operations-Manual.doc, the uplink frequency
is listed as 29.401 MHz.
At https://github.com/alpov/PSAT-2/blob/master/README.md, the uplink
frequency is listed as 29.48 MHz.
At http://aprs.org/psat2.html, the uplink frequency is listed as 28.120 MHz
(in text, w/ a graphic indicating "29.XX?").
Thanks!

PSAT2 Ten meter PSK31 uplink and UHF FM 435.350 downlink is ON.
Who will be the first to nail down the ten-meter PSK31 center uplink
frequency?
It should be around 29.40X.
The Total Doppler shift during a pass should be about 1 KHz.
What 29.40X TX uplink gives 1.5 KHz in the UHF passband at the center of the
pass?
Thanks, Ill correct links below. (PSAT has uplink on 28.120. But PSAT2 is
on 29.40X)

HUGE THANK YOU to JA0CAW, who spotted ARMADILLO over Japan! He has posted
the beacon on twitter @??????. Thanks also to Scott, K4KDR for connecting
the dots for us! This is the first beacon heard for our satellite!!!Our team
is currently still working on stations and a decoder to post on github for
everyone, we just need to verify with the University that it's alright to do
so.For now, our beacon features our vehicle's callign is ascii and quotes
from the video game "Portal", so give us a listen! Based on info from
CalPoly and from PSAT, we think we are either Object J or Object K in the
database, 44347 or 44348.Parameters again are 437.525MHz DL, 19200 baud,
GFSK, beacons every 10 seconds, vehicle callsign WH2XYR.
Overall we are inexperienced with respect to interacting with the amateur
community (and building satellites for that matter) but we already owe
everyone a lot for helping us find our satellite while we are indisposed, SO
THANK YOU VERY MUCH!
