Hams Contact Atlantis/Mir Astronauts
ARRL has received dozens of reports from amateurs that have made successful
voice contacts with the crew aboard the Space Shuttle Atlantis and the Mir
Space Station Complex. The two spacecraft have been docked together since
Wednesday, and are orbiting 245 miles above the earth at approximately
17,000 mph.
Earlier this week, the Atlantis astronauts completed 5 scheduled ham radio
contacts with US students as part of the Shuttle Amateur Radio EXperiment or
SAREX. These groups included students from Franklin Junior High School in
Pocatello, Idaho, Norwalk County schools in Connecticut, Lake Street
Elementary School in Crown Point, Indiana, Round Lake-area schools in
Illinois, and Quimby Oak Junior High School in San Jose, California. The
students were assisted by their local Amateur Radio clubs and many AMSAT
SAREX volunteers.
Amateurs trying to make random contacts with the astronauts should be aware
the crew is using separate receive and transmit frequencies. Do not transmit
on the shuttle's downlink frequency. The downlink is your receiving
frequency. The uplink is your transmitting frequency. The FM voice downlink
is 145.84 MHz. The FM voice uplinks are 144.45 and 144.47 MHz. The crew will
not favor either uplink frequency, so your ability to communicate with SAREX
will be the "luck of the draw." Transmit only when the shuttle is within
range of your station, and when the astronauts are on-the-air. The
astronaut's call signs are KB5AWP, KC5NRI, N5SCW, KC5ACR, and KC5RNJ. There
is no hardware to support packet radio contacts from the shuttle during this
flight.
QSL cards and reports may be sent to ARRL EAD, STS-74 QSL, 225 Main Street,
Newington, CT 06111-1494, USA. Include the following information in your QSL
or report: STS-74, date, time in UTC, frequency and mode (FM voice). In
addition, you must also include a SASE using a large, business-sized
envelope (#10) if you wish to receive a card. The Greater Norwalk Amateur
Radio Club in Norwalk, CT has generously volunteered to manage the cards for
this mission.
