Possible ISS Voice Contacts on Field Day
David Jordan, AA4KN, ARISS Public Relations
Current discussions between the ARISS team and NASA suggest the
possibility of voice contacts with the International Space Station
(ISS) during Saturday’s ARRL Field Day activities this coming weekend.
In a June 23 email, Kenneth Ransom, the ISS Ham Radio payload
developer, stated “I have received a response from astronaut (Reid)
Wiseman that he is willing to try and work some stations on Saturday.
Pass times begin very soon after the start of Field day.” Wiseman
would operate under the call sign, NA1SS. Should Alex Gerst
participate, he would use the call sign, DP0ISS.
If voice operation does occur, It will likely take place from the
Columbus (COL) module using the standard Region 2 uplink frequency of
144.49 MHz and 145.800 MHz for downlink. It’s expected that the packet
system will be operational on 145.825 MHz during periods when the crew
is not available.
It’s not clear whether any of the Russian crew would participate from
the Russian module, but if so, they would be directed to use 437.550
MHz for any contacts using the call sign RS0ISS. The COL would also be
available to their crew using the VHF frequencies above, if Wiseman is
Listed below are approximate pass times and a chart showing ISS passes
for the Field Day weekend. The pass times shown are not definite,
scheduled times with the crew. They may or may not be able to support
these times. And, updates to this tentative plan will be released as
they become available.
