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. 

Enjoy!
