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 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.
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
CALL SIGNS:
FM voice call signs KC5FVF
FM packet call sign W5RRR-1
QSL VIA: Send reports and QSLs to ARRL EAD, STS-70 QSL, 225 Main Street,
Newington, CT 06111-1494, USA. Include the following information in your
QSL or report: STS-70, date, time in UTC, frequency and mode (FM voice).
In addition, you must also include a SASE using a large, business-sized
envelope if you wish to receive a card. The Sterling Park Amateur Radio
Club in Sterling, VA has generously volunteered to manage the cards for
this mission.
SHUTTLE TRACKING: Current Keplerian elements to track the shuttle are
available from the NASA Spacelink computer information system:
BBS: (205) 895-0028 [VT-100, 8-N-1]
Telnet, FTP, and Gopher: spacelink.msfc.nasa.gov
World Wide Web: http://spacelink.msfc.nasa.gov
Internet TCP/IP address: 192.149.89.61
Keplerian elements may also be downloaded from the ARRL BBS: (203) 594-
0306. Also, the Johnson Space Center ARC BBS will have the latest element
sets available during the flight: (713) 244-5625.
The following are prelaunch Keplerian elements for STS-70:

Center, and posted by Dave Ransom, RPV Astronomy BBS.
CONFIGURATION: During STS-70, the SAREX hardware will be flown in
configuration C.
SAREX configuration C consists of a handheld 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 handheld
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).
