Transponder works well even on a 12-13 degree pass here. Beacon decodes on
a separate track. TX from 10m SSB shows up separately. You will need to keep
moving your cursor (at least in DM780) to track and decode the SSB. Now,
all I need is a better pass and someone to answer

Subject: [amsat-bb] PSAT Status (day 4)
PSAT PSK31 435.350 MHz FM downlink is full quieting with 6 bars using a
decent UHF Yagi.
But we have not seen any users other than those using the 28.120 PSK channel
on HF normally. We welcome people to experiment with it.
Everyone within the 28.120 to 28.123 MHz ten meter passband will be uplinked
and heard on the 435.350 MHz downlink.
The Naval Academy's PSAT seems healthy with plenty of power (we are keeping
the APRS digipeater off to allow max power for PSK31).
PSAT 's radio and packet system are a simple $250 APRS tracker
http://www.byonics.com/mtt4b sent to space. The PSK31 transponder is a
single 3.4" square circuit board made by Brno Universtiy in the Czech
Republic. The CPU for controlling bulletins and timing is a simple Parallax
Basic Stamp.
PSAT is actually only about a 1U cubesat but in a 1.5U package since the
flight was available and it gave us more power for our NON-SPACE solar
cells. We are using standard silicon that are only half as efficient as
multi-junction cells, but only cost 1% as much.
PSAT has a single 21" VHF and 72" long HF whip. It has two UHF 6"
orthogonal monopoles, all of very thin Nitinol wire.
More details will eventually follow as the page will be updated over the
coming weeks. http://aprs.org/psat.html
* PSAT packet telemetry is OK, Digipeater will be off (secondary mission)
* PSAT PSK31 transponder is ON with 28.120 MHz uplink! (primary mission)
* WOD data fixed. Spin data now available. Right now it is at 3 RPM with
+Z pointing 45 deg off Sun
* Launch TLE elements (below) are still very good
* http://PCSAT.APRS.ORG web page is now capturing PSAT telelmetry that
users inject into the APRS-IS
* BRICSAT telemetry has been heard but is cycling OFF due to low power
* BRICSAT PSK31 downlink (also FM) has also been heard barely (when ON)
* USS Langley not heard
FREQUENCIES:
PSAT: 145.825 - 1200 baud AX.25 telemetry - digi off
PSAT PSK31-5: 435.350 FM down, 28.120 SSB PK31 uplink - Brno University
Xponder
BRICsat: 437.975 - 9600 baud telemetry evry 20s BRICsat PSK31-6 - same as
PSAT but PSK TLM on 375 Hz (PSAT on 315 Hz)

I left the rig and packet software running today while I was at work. I
was listening to the LightSail beacon on 437.435 MHz. I had one entry on
the screen when I got home:
1: Fm V-3 to 70-9 Via uH, , , -6 <RR P/F R5>[07:25:21]
No idea what it means, not sure if it was LightSail or not. Posted as an
FYI. Curious to know what it might be.

The original email from David, reprinted below noted the "Stopping of the
435 downlink carrier and Bob WB4APR came back and said that the transponder
is in an "Auto" mode which waits for a PSK signal and then turns on. My
experience the other morning was that this was true, but as David says
below, he was surprised by it turning off periodically. My surprise was
that I was able to repeatedly turn it on when I started transmitting on
28.120 +1Khz, but before my CQ ended, the carier would quit. I repeatedly
brought it up and also saw other not so copyable psk carriers on the
waterfall but the transponder seemed not to stay on long enough to keep a
full QSO going. I know for a fact because I duplicated at least three times
turning on the FM carrier about 2-3 seconds after I started to uplink. I
personally have yet in my several feeble efforts, been able to make a full
QSO although I have been emailed by several to say that they did indeed hear
me. This morning, 5-27 1207Z pass I was bad and had my RX radio to the
wrong frequency but will give another shot at the 114xZ pass on 5-28 to see
if I can make progress on making a Q.

Congratulations Bob and USNA on another successful spacecraft.
I listened for the first time this morning and could hear the beacon and
transponded PSK31 without any trouble.
But I was not expecting the 435.350 carrier to stop every now and again.
What determines if the carrier is on or off. - Beacon timing.- OK, but is
the transmitter also PSK activated in someway? Or is it a timer.
Very nice for saving power.
Thanks

Anybody hear anything from the ISS digipeater this morning (between 1019 and

nothing.
Is the digipeater off or am I "off"?

Hi,
ARISS equipment in Columbus is deactivated till June 1.
Reason is maintenance on other equipment needing temporary removal.

The packet modems relay on a CRC checksum of the packets to validate the
data received as a good packet.
In some situations, like yours when a modem is listening a long time,
the noise can "forge" a "good" packet. This is a statistically proved
fact, the CRC is not as strong as we wish for this task.
I'm not saying that this is a noise forged packet, but it's a possibility.

A couple of questions:
How much power (to a dipole) is recommended for uplinking on 28.120 PSK31?
Also, what is it's altitude?
And, how long is its expected lifespan?

WB4APR recommends no more than 25 watts.
The prelaunch orbit estimate I saw was a 700 km x 350 km orbit with an
expected orbital lifespan of 3 years. I'm not sure how close that is
to the final orbit.
