ADDITIONAL INFORMATION FOR AMATEUR RADIO OPERATORS-
SAREX RADIO FREQUENCIES: During most SAREX missions, many of the crew members will
make random contacts with earth-bound hams. They make these contacts
during their breaks, before and after meal time, and during their pre-sleep time. In fact, over the
past years the astronauts have contacted thousands of amateurs around the world. On many
missions, they have even carried a 2-meter packet radio station. Innovative computer software
allows the crew to operate the packet gear in an "unattended" mode, allowing amateurs to make
contacts with the ROBOT station
when the astronauts are working or sleeping.
The SAREX Working Group has designated the following frequencies
during this mission.
FM Voice Downlink: (Worldwide) 145.55 MHz
FM Voice Uplink: 144.91, 144.93, 144.95, 144.97, and 144.99 MHz
FM Voice Uplink: (Europe only) 144.70, 144.75, and 144.80 MHz
FM Packet Downlink: 145.55 MHz
FM Packet Uplink: 144.49 MHz
The crew will use separate receive and transmit frequencies. PLEASE do not
transmit on the shuttle's DOWNLINK frequency. The DOWNLINK is your receiving
frequency. The UPLINK is your transmitting frequency.
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 shuttle's
station is on-the-air.
CALL SIGNS:
FM voice call signs: KC5RNI, KC5BTK and KC5FVF
FM packet call sign: W5RRR-1
QSL VIA: Send reports and QSLs to ARRL EAD, STS-83 QSL, 225 Main Street,
Newington, CT 06111-1494, USA. Include the following information in your QSL
or report: STS-83, date, time in UTC, frequency and mode (FM, voice or
packet). In addition, you must also include a SASE using a large, business-
sized envelope if you wish to receive a card.

Packet: WA3NAN on 145.090 MHz in DC area
CONFIGURATION: During STS-83, the SAREX hardware will be flown in
configuration C.
SAREX configuration C consists of a hand-held transceiver, I/F module, PGSC
(serves as the packet data terminal), spare battery set, window antenna,
packet module, SAREX headset assembly, personal recorder, and the required
cable assemblies. The packet module contains a power supply and packet TNC.
The power supply provides power for the TNC and the hand-held transceiver. The
TNC interconnects with a radio transceiver so that data to and from the
computer is transmitted to and received from other amateur radio stations.
Configuration C is capable of operating in either the voice or data mode in
communications with amateur stations within LOS of the Orbiter. This
configuration can be operated in the attended mode for voice communication
and either the attended or automatic mode for data communications. The payload
control weight is 45 lb. (20.41 kg).
