For the next 8 days you will be able to Digipeat APRS posits though both
PCSat and ISS on 145.825Mhz.
If you use the path of APRS via WIDE,WIDE,SGATE it may be possible to
digipeat between the two space ships.
There are 3 SGate running in VK/ZL at present to capture your transmissions
and gate them to the internet.
REMEMBER though only transmit once every 2 minutes and only attended
operations are acceptable.
See below for more details.

<kenneth.g.ransom1 at jsc.nasa.gov> 1/31/05 11:42:43 AM >>> The International
Space Station's amateur radio equipment is scheduled to temporarily change
frequency to 145.825 simplex on Feb 2. The change will occur after the 12:54
UTC school contact with the Air Training Corps in Norfolk, England. This
brief change will allow operators to take advantage of the recent return of
PCSAT to operational status and the orbital dynamics between the two
satellites being optimal for numerous relay opportunities. It will also be a
chance to test the ability of the Kenwood to interact with another satellite
digital system since the previous joint test utilized the Phase 1 Ericsson
radio. Several long mutual passes are expected during this brief operation
between the two satellites.
As a reminder, Bob Bruninga has stipulated NO unattended operations to
minimize impact to the power budget on PCSAT and recommends the following
path for attempting double hops. UNPROTO CQ VIA WIDE,WIDE. More info about
PCSAT is available at www.ew.usna.edu/pcsat <www.ew.usna.edu/pcsat> .
The chance to try and digipeat through both systems is scheduled to conclude
Feb 10 when ISS is scheduled to make the next school contact. After that
contact, the radio will return to the default packet operating frequency of
145.99 up and 145.80 down.
