Possible ISS Voice Contacts on Field Day

ARISS NEWS RELEASE no. 14-02

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 not operating.

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.

OSCAR Number for LituanicaSAT-1

June 28, 2017June 8, 2014 by amsat admin

In a message to the LituanicaSAT-1 team, AMSAT-NA OSCAR Number Administrator Bill Tynan, W3XO announced, “LituanicaSAT-1 has met all of the requirements for an OSCAR number. My findings from information provided to AMSAT-NA and IARU officials confirm this to be true. Accordingly, under the authority vested in me by the AMSAT-NA President, I do hereby assign LituanicaSAT-1 the designation LituanicaSAT OSCAR-78, or LO-78. I, and all of the amateur radio satellite community, wish LituanicaSAT OSCAR-78 a long and successful mission.”

On behalf of the LituanicaSAT-1 team, Simon Kareiva, LY2EN replied, “It is my honor and pleasure to accept this assignation. Our team is focused to keep LO-78 operational for the benefit of amateur radio as long, as it is possible for a small cubesat. Thank you very much, Simon LY2EN.”

The LituanicaSAT-1 team has announced activation of the FM transponder. A general rule to find out if the transponder is working at the moment is to monitor the beacon frequency on 437.275 MHz. If you can hear CW FM beacon it means that transponder is off, if you cannot hear it – the transponder is on. The transponder frequencies are approximately 435.1755 MHz (+/- 10 kHz Doppler shift) for the downlink and 145.950 MHz for the uplink with 67 Hz CTCSS.

AMSAT videos from Dayton 2014

June 28, 2017May 31, 2014 by amsat admin

Tom, K3IO, was the speaker at the AMSAT/TAPR Banquet at the Dayton Hamvention. In his talk, he remembers the many Elmers that helped him with his hobby and career.

Barry, WD4ASW and AMSAT President, gives an update on AMSAT, including changes to the BoD roster, regulatory issues, membership and finances.

As AMSAT’s new VP of Engineering and Fox satellite team leader, Jerry gives an update on the Fox-1 satellite, its design, milestones, and launch opportunities. He also looks ahead to Fox-1B, Fox-1C, Fox-1D, and Fox-2.

Howard, G6LVB, gives a fascinating look into the launch and operation of the FUNcube-1 satellite, and a tentative calendar of the next three FUNcube satellites.

Drew, KO4MA, reviews six operational amateur satellites, then previews another dozen amateur satellites that will be launched soon, or should be turned over to amateur use when their primary mission is completed.

Frank, KA3HDO, gives an update on Amateur Radio on the International Space Station, including the radios and antennas on board, the impact of funding changes at NASA, and the new Ham TV system.

EMike, KC8YLD, explains how K-16 education is key to the launches of future amateur radio satellites, and discusses the joint work of AMSAT, ARRL, and NASA.

In this brief video, Spence, WA8SME, shows the next version of the WRAPS rotor with circularly polarized antennas and discusses an updated broadband preamp that now includes an antenna polarity switch.
