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

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 QSOs.
