[OZAPRS] APRS / PCSAT Ground Stations audit.

Fri Aug 19 12:15:40 EST 2005

Gday Chris,

Thanks for the update. I’ll update the web page.
(http://www.aprs.net.au/sat_aprs_information.htm)

Can you give a brief description of your station setup. Especially the
antenna system you are using.

For information both ISS and PCSAT2 packet will be off for 24hrs or so
while the astronauts do an EVA today.

My understanding is that after the EVA ISS will be operating in
APRS/Digipeater mode and PCSAT2 will be in TLM/PSK32 mode when no school
contacts are in progress. PCSAT2 may not be operational during school
contacts.

Cheers

Richard

Hi again Richard,

I’ve changed my system, so that it QSYs to 437.975 MHz (+/- Doppler)
whenever the ISS is above the horizon, instead of listening on 145.800MHz.

Here’s a snippet from http://www.findu.com/cgi-bin/pcsat2.cgi (times are
dd:hh:mm:ss age before 1240 Z today):

Hi Richard,

My APRS station (VK6KCH-0) automatically QSYs to 145.800 MHz whenever
there is an ISS pass, or to 145.825MHz when there’s a PCSAT pass.  The
rest of the time, it spends on 145.175MHz.

Regards,

Chris

Hi,

With the renewed interest in APRS satellites with PCSAT2 and the increase
in the number of ground stations I’d like to get an idea of which stations
are monitoring what?

Eg.

VK3JFK-4 PCSAT2 1200bd TLM on 437.975Mhz

VK3UKF-6 ISS 1200bd on 145.800Mhz

VK3JTM-6 ISS 1200bd on 145.800Mhz

Cheers,

Richard
