ISS crew may be on the air
for Field Day

The ARRL reports NASA Astronaut *Reid Wiseman KF5LKT* may be on the air for
ARRL Field Day from the International Space Station (ISS) June 28-29

NASA ISS Ham Radio Project Engineer Kenneth Ransom, N5VHO, said “I have
received a response from Wiseman that he is willing to try and work some
stations on Saturday,� Ransom said on June 23.

“Pass times begin very soon after the
start of Field Day.� Wiseman would use
the NA1SS call sign and operate from the Columbus module on the standard
VHF frequencies of 144.490 MHz up and 145.800 MHz down.
His Field Day exchange would be 2A DX.

The ISS packet system should be operational on 145.825 MHz when the crew is
not using voice. Should European Space Agency Astronaut Alex Gurst, KF5ONO,
participate, he would use the call sign DP0ISS on VHF from the Columbus
module radio during passes when Wiseman is not on the air. His FD exchange
also would be 2A DX.

Ransom said it’s unclear whether any of the Russian crew members now on
board the ISS will participate from the Russian module, but if they do,
they would operate on 437.550 MHz simplex (±Doppler shift), using the call
sign RS0ISS. None of the current cosmonauts has an Amateur Radio license,
but under Russian regulations, Ransom said, a club trustee may authorize
anyone to operate using the club call sign, RS0ISS. The FD exchange again
would be 2A DX. The Columbia module station would also be available to
their crew members using144.490 MHz up and 145.800 MHz down, if Wiseman is
not operating.

The ISS circles the Earth about once every 90 minutes. Some passes will
favor some parts of the country while other passes will favor others.
Wiseman has indicated that he will be willing to try these approximate pass
times, but crew members may or may not be able to get on the air.

Saturday, June 28
North America (1809-1831 UTC)
Hawaii (1936-1947 UTC)
North America (1947-2008 UTC)

Working an ISS crew member does not qualify for satellite bonus points. As
the Field Day FAQs explain, “While the ISS is by definition a satellite,
the purpose of the satellite QSO bonus is to complete an Earth-to-Earth
contact via an Amateur Radio satellite. Since the ISS contact doesn’t relay
back to Earth, it doesn’t meet that requirement, though it does count for
regular QSO credit — and is sure to generate excitement at your site!� But
working a station on Earth through the onboard digipeater would qualify and
count as a valid Field Day contact. — Thanks to Kenneth Ransom, N5VHO, and
David Jordan, AA4KN/ARISS

Note: the Uplink frequency of 144.490 MHz mentioned above is not used when
the ISS is over Europe and Africa. Instead an uplink of 145.200 MHz may be
used or the uplink and downlink could both be 145.800 MHz.
