To: ham-space@ucsd.edu Hello, I was looking out for a 2M all-mode rig for possible satellite work, and someone had a Kenwood (actually "Trio") TR-9000 rig for sale. I know it's an older one, but is this one of the better rigs, or is it a dog? What do you think they are worth now?

The Langley chapter of the National Space Society is going to build a high power rocket with one of the local schools and we would like to get telemetry from the rocket, i.e., altitude, downrange distance, and save the data to a computer file for later analysis. We are also going to modify rawinsonde equipment to obtain meteorological data from the rocket. Any information on available boards, antennas, computer software, etc. would be greatly appreciated. Thanks in advance.

At 10:42 UTC on February 6, Sergei Krikalev, U5MIR, initiated contact with a school group at the House of Science and Technology for Youth in Moscow, Russia. This represents the first time a cosmonaut on a U.S. space shuttle has communicated with a group in Russia. Leo Lebutin, UA3CR and Valery Agabekov, UA6HZ were the prime school group coordinators for this contact. During the contact Aleksandr Kaleri, U8MIR, gave Sergei greetings from Russia. Six students were able to ask their questions to the crew on the Space Shuttle DIscovery. In addition, several cosmonauts were on hand to hear the communications. The SAREX contact was also broadcast live throughout Russia on HF (80 meters, 40 meters and 20 meters) as well as VHF. The packet robot on the Space Shuttle Discovery has been quite busy today. At last report, the QSO sequence number was nearing the 2000 mark. Many hams from around the world have reported booming packet radio signals from the Shuttle Discovery. Those of you who have heard or worked the STS-60 crew and wish to receive a QSL card need to send your signal report and an SASE or an envelope and IRCs to the following address: STS-60 QSL Education Activities Division ARRL 225 Main St Newington, CT 06111 The official SAREX element set for today will be GSFC-005. This element sent was generated by Ron Parise, WA4SIR of the Goddard Space Flight Center. Gil Carman, WA5NOM reports that the predictions using GSFC-005 differed from GSFC-003 by approximately 2 seconds during orbit 50.
