ARLS005 ISS crew could be on the air for Field Day.
International Space Station crew members John Phillips, KE5DRY, and Sergei
Krikalev, U5MIR, may be on the air for ARRL Field Day, June 25-26. ISS Ham
Radio Project Engineer Kenneth Ransom, N5VHO, at Johnson Space Center, has
reviewed potential ISS pass times, and he says a few are favorable for US
stations--although some will occur during the very early morning hours.
Phillips and Krikalev will use the Amateur Radio on the International Space
Station (ARISS) radio gear aboard the spacecraft.
''Hams on the ISS will try to be on for ARRL Field Day,'' Ransom said.
''The crew can make contacts anytime during the 1800 UTC June 25 to 1800 UTC
June 26 period as time permits. Most activity will be over North and South
America, but stations worldwide should be listening.''
Ransom says the pass times are only recommendations, and there is no
guarantee that either Phillips or Krikalev will actually be on the air
during any of them. Passes marked by asterisks (*) are recommended as
desirable ones for voice contacts with Amateur Radio stations on the ground.

Phillips will operate as NA1SS and handing out ''1 Alfa ISS'' for a report.
If Expedition 11 Commander Krikalev gets on the air too, he'll identify as
RS0ISS and give the same exchange. In the past, crew members have operated
from both the Phase 1 and Phase 2 ARISS stations using 2 meters and 70 cm.
The standard ISS voice frequencies for contacts in ITU Region 2 are
144.49 MHz up and 145.80 MHz down, FM.
If the astronauts can't get on the air to make voice QSOs, the RS0ISS packet
station should be on and available for ground stations to work each other
via the packet digipeater using ''ARISS'' as the alias for the call sign in
UNPROTO mode. Frequencies are 145.99 MHz up and 145.80 MHz down.
ARRL Contest Branch Manager Dan Henderson, N1ND, notes that ISS voice or
direct packet contacts with the ISS do not count for bonus satellite contact
points because the ISS is not an ''Amateur Radio satellite'' as event rules
specify. Packet contacts relayed via the ISS are valid.
''The ISS contacts do not count for satellite credit, since they are
point-to-point, whereas the traditional satellite QSO is a relayed
Earth-satellite-Earth two-way contact,'' he explained. Field Day has no
specific rules relating to ARISS operation because there's no guarantee that
the crew will be able to get on the air for the annual exercise.
During Field Day 2004, astronaut Mike Fincke, KE5AIT, operated NA1SS on 2
meters, while Expedition 9 Commander Gennady Padalka, RN3DT, was on the air
from RS0ISS on 70 cm. Between them, they racked up more than five dozen
