I'm still looking for QSOs through the ISS digipeater. There's a pass in a
couple of minutes, but I'm open to making a sked in the future.
Thanks!

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

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 PSK31 is always in AUTO mode. It will come up whenever it hears PSK31
on the 28.120 uplink.

Ok, so I'm hearing something I cannot verify. I have be trying to capture
9600 baud packets from BRICSat. Now I discover on the IC-9100 yahoo group
someone is saying the IC-9100 does not handle 9600 baud packets over the USB
port. I find this hard to believe but can any confirm or deny this claim?
I have had issues catching anything with the IC-9100 and 9600 baud packets
so was wondering if it was the setup or the radio.
All feedback welcome please..

Is the uplink on 28.120 + audio or does the psk31 signal need to
be at 28.120 i.e. 28.119 USB with 1000 Hz psk31?
I copied some beacons but didn't see anything from my attempt to
uplink.

Mike, I used my day to day DM780 settings. Dial setting was 28.120 and I
just picked the middle of the waterfall to TX.
On the RX, you need to keep the cursor moving as the trace moves quickly. It
does not stay in one place like normal psk

Okay, I must be misunderstanding how this works. I thought the
down link was FM like the beacon which for me is at 308 Hz on
the waterfall.

It is, but your uplink signal is going to be Doppler shifted, so it's
going to drift through the waterfall (+/- 0.7 kHz through a pass),
unless you are controlling your transmit frequency for Doppler.

Hi All,
I picked up the Getting On The Sats book at Dayton this year and it makes
mention of TV rotators. Another local Radio Shack is going under. Is it
worth picking up their antenna rotator since it's probably at 60% off?
Thanks and 73

Thanks Paul,
The doppler would be enough to prevent the decode, but not
enough to prevent me from seeing the trace, if I hit the
bandpass. So far I haven't seen anything but the beacon and
maybe something that looked like one of the MFSK type modes. Do
you know the frequency of the actual center of the uplink
bandpass and how wide it is?

This is true, the unprocessed FM audio require for 9600 baud packet is only
on pin 4 of the DATA2 jack, it is not available through the USB soundcard
built in to the 9100. :-(

Ok, so I'm hearing something I cannot verify. I have be trying to capture
9600 baud packets from BRICSat. Now I discover on the IC-9100 yahoo group
someone is saying the IC-9100 does not handle 9600 baud packets over the USB
port. I find this hard to believe but can any confirm or deny this claim?
I have had issues catching anything with the IC-9100 and 9600 baud packets
so was wondering if it was the setup or the radio.
All feedback welcome please..
