Challenger Learning Center in Kenai, Alaska contacts the ISS

ISS Amateur Radio

I just wanted to let you folks know that this Saturday morning August 05 starting at 0712L we were successful in contacting Jeff Williams on the ISS. We had a solid contact that lasted for almost 8 minutes. We had the home school students from IDEA and they all had some interesting questions for the Science Officer aboard the ISS. The contact took place at the Challenger Learning Center in Kenai, Alaska. This is the first school contact for Alaska and we are not really a school but we had some very good cooperation from Kenneth Ransom, N5VHO with NASA at JSC in Houston, TX who gave us tips and info we needed. I worked Jeff on split frequencies on 2 meters. Uplink was on 145.200 and downlink was 145.800. I was using IC910H with full power on 2 m. My antenna was an arrow with a pre-amp. I disconnected the UHF side and used the 3el 2m side only. I had it mounted on a tripod mount on the roof of CLCA. I also had az-el rotors to track the space station. The radios are back home now but the antenna is still on the roof. I will remove it later next week.

SSTV tests planned from ISS, school contacts set for German astronaut

ISS Amateur Radio

The Amateur Radio on the International Space Station (ARISS) program reports that ISS Expedition 13 Commander Pavel Vinogradov, RV3BS, has set up a camera to use for slow-scan television (SSTV) from the ISS. Vinogradov plans to soon test the system over Moscow on 144.49 MHz -- perhaps as early as this weekend -- and radio amateurs within range are encouraged to receive the SSTV images. For now, the SSTV system will only be used to transmit. Due to various issues with 144.49 MHz in Europe, the European and US ARISS teams will be recommending frequencies for use over other countries. Responding to a request from the European Space Agency (ESA), ARISS has scheduled school group contacts at three ESA-organized events for new Expedition 13 astronaut Thomas Reiter, DF4TR (photo). The Greek Minister of Education asked for a QSO with Reiter during the ESA Space Camp in Greece July 29. This is expected to be a major event, with the minister asking an interview question, and Greek national TV covering the occasion. A second QSO will be with visitors at the Museum of the Swiss Air Force. A third contact with visitors to Germany's Mannheim Museum is set for July 31. Reiter, the first German astronaut to be a part of an ISS crew, likely will use the space station's German call sign, DP0ISS.

ISS voice crossband now active

ISS Amateur Radio

Ground stations in Europe report the crossband repeater mode on ISS is
active. Jeff even made a brief appearance at the mic.

Enjoy and good luck on Field Day.

Success Tips for Using the ISS Voice Repeater

ISS Amateur Radio

Unlike any other FM satellites that operate in Mode V/U (Mode J) the ISS is operating in Mode U/V (Mode B). While this seems to be of little consequence to most owners of dualband handheld transceivers, mobile rigs and base stations, some important factors can spell the difference between success and failure. Let's consider these.

Downlink/Uplink Frequencies

The ISS repeater downlink is 145.800 MHz, which is the normal FM voice and the RS0ISS packet system downlink worldwide. (The non-repeater FM voice uplink frequencies are 144.49 MHz in Regions 2 and 3 and 145.20 MHz in Region 1. The packet uplink frequency is 145.99 MHz worldwide.)

N.& S. America Pass times for Field Day

ISS Amateur Radio

Here is a list of International Space Station Field Day pass times for North and South America. The Amateur Radio on the International Space Station (ARISS) program announced earlier this month that the Phase 2 ham station aboard the ISS would be on the air in crossband repeater mode for QRP staions over Field Day weekend, Saturday and Sunday, June 24-25. The chances of talking to one of the crew members appear to be minimal, however. Additional information is available in the following story.

ISS FD Passes times listed below are for over North and South America and are in UTC! Passes during the crew sleep period are marked **.

Crossband Repeater to be available for QRP operations

ISS Amateur Radio

The ARISS Phase 2 station will be configured in crossband repeater mode--437.800 MHz up/145.800 MHz down, but it's being requested that ONLY low-power (QRP) Earth stations access the system. The definition of a QRP station for this activation will be the same criteria that AMSAT is using for its QRP operations on ECHO (AO-51) for Field Day.

To attempt to keep this simple a low power station will be defined as a station which can deliver no more than 10 watts to a vertical or handheld antenna. Some examples of Low Power Stations:

Fabiano PY5RX meets Astronaut Marcos Pontes

ISS Amateur Radio

Few weeks after Marcos Pontes returned from his ISS mission he attended a public speech in the city he was born: Bauru (São Paulo).
Thousands of people welcomed the Astronaut as he arrived piloting a small airplane.

Fabiano PY5RX was able to contact Pontes during his short mission, so he got invited to join the speech and receive from Marcos hands a special gift that commemorates the contact.

Pontes spent some nice words about Amateur Radio explaining how important it is for the crew to contact people on the ground.
