Russ Tillman, K5NRK, AMSAT-NA Journal editor, tells ANS the Vicksburg Amateur Radio Club will sponsor special event station K5ZRO during the 16th AMSAT Annual Meeting and Space Symposium.
The special event station will operate from Vicksburg, October 17th and 18th, using the following frequencies and satellites:
HF: 7.245, 14.245, 21.345 and 28.445 MHz
VHF: 146.520 MHz
Satellite: AO-10, AO-27, RS-12/13, FO-20 and FO-29
During the Symposium, participants are invited to visit the special event station, located at the home of Ed Magruder, N5QDE.
QSL's will be handled through N5QDE.

Ray Soifer, W2RS, representing AMSAT as an observer at the International Amateur Radio Union Region 2 Conference in Porlamar, Isla Margarita, Venezuela, successfully operated as YV7/W2RS on several AO-27 satellite passes.
The conference ran through October 2, 1998. Porlamar is located in grid FK80bw.
Initially, YV7/W2RS worked four stations on two AO-27 passes: N1XAU, N1JEZ, K8TL and KB8TJX. Initial operation was a test to see if a live demonstration during the conference would work.
During the first live conference demonstration, four stations were worked: KD2BD, W8WRP, KD4ESV and N1XAU. Ray reported the live contacts had a very desirable effect, showing IARU delegates just how easy it is to work AO-27. All YV7/W2RS operation was conducted using a 5-watt handheld dual-band radio, internal battery and a dual-band whip antenna.
Six stations were worked on the final pass, bringing the total number of different stations worked on all AO-27 passes from the conference to 15. W2RS even had IARU President Dick Baldwin, W1RU, acting as his logger during one of the passes!
Operation was also scheduled for RS-12/13, but because of a high local noise level on 10-meters and the unavailability of 2-meter CW/SSB downlink equipment, no contacts were made.
Ray would like to thank everyone who helped make the AO-27 contacts a success, including those operators who stood by during a pass to allow him to contact as many stations as possible.
QSL requests for YV7/W2RS should be directed to the W2RS callbook address.

The American Radio relay League has announced another volume of available videos, with several of interest to satellite operators. Called 'Amateur Radio Far Away', Volume 12 includes programs that focus on amateur radio in space, such as:
Volume 12 -- Amateur Radio Far Away (ARRL item number 6974) is available from the League for a nominal fee. To order or for more information, contact Margie Bourgoin, KC1DCO, in the ARRL Educational Activities Department at the following e-mail address:

Dave Larsen, N6CO, MIREX president, tells ANS that starting in October Mir shortwave listener reports will be accepted by MIREX, with successful reports earning a Mir QSL card. N6CO reports he has "set aside" 500 QSL cards for this event.
All worldwide SWL stations are eligible to receive a Mir SWL QSL card following successful reception.
The requirements for earning a Mir SWL card include:
N6CO reports that if all 500 cards are gone, any additional received IRC's will be returned to the sender.
All Mir SWL QSL card requests (except Europe) should be sent to the following address:

N6CO reports he has recently mailed 345 Mir QSL cards.
MIREX has announced an on going APRS School Days Test. MIREX is allowing schools to use APRS for position and status reports via R0MIR. Non-school stations are asked to refrain from using APRS type transmissions or beacons via R0MIR.

The RS-12 satellite has seen many recent changes in operation during the past weeks. Modes K, T, KT and simultaneous RS-13 operation have all been reported by a number of stations. Both Mike, WA6ARA, and Peter, KD7MW, report the RS-12 beacon is now transmitting the word 'test' in slow CW after the usual fast CW telemetry.
Sid, AH6HH reports a solid contact between Hawaii and Washington recently. Kevin, WB5RUE, reports few stations on RS-12 although he can hear his own downlink S-9 or better at times. Al, XE2YVW, reports the same. John, K2JF, thanks Tom, WB4FWQ, for a nice contact but also wonders where all the operators are. Cristi, YO3FFF, reports a RS-12 CW QSO with IK5VLO.
No official word from the satellite controllers has been received. ANS recommends monitoring each satellite carefully to determine the transponder in operation and which mode it is operating in.
RS-12/13 command is now in the hands of Alex Papkov, in Kaluga City, Russia.

John, K2JF, reports on a recent RS-15 pass he copied only a weak return to his CW uplink, he did not hear the satellite beacon at any time, nor did he hear any other signals.
Dave, WB6LLO, reports he has prepared a "quick and dirty" set of operating instructions for RS-15 at the following URL:

Mike, N1JEZ, reports AO-10 continues its slow improvement, working HB9JOI. Signals were weak at 3X2 each way with a very slow frequency shift and some QSB. Don, KC4YRT, tells ANS he worked 9H1IF on the satellite. Dirk, ON1DLL, reports working HB9JOI recently with the satellite at the 38,000km range.
Stacey Mills, W4SM, has more information about the satellite at the following URL:

Downlink: 436.792 MHz FM
AO-27 TEPR States are currently:
4 = 36 = 18 Minutes
5 = 72 = 36 Minutes
This means AO-27's transmitter turns on 18 minutes after entering the Sun and stays on for 18 minutes. AO-27's transmitter is turned off at all other times during the orbit. N4USI reminds stations that this happens on every orbit, approximately 14.2 times a day. The current TEPR settings will cause the satellite to be on during the daytime at northern latitudes.

Users of OSCAR-11 may be interested in two new WOD software packages have recently added to the Oscar 11 web site. The first package enables various WOD channels to be compared with the solar eclipse status of the satellite. The second package compares measured and calculated magnetic fields encountered by Oscar 11. Both packages are of an advanced nature, users will need experience using the other WOD packages on the web site and a spread sheet program.

The TMSAT-1 micro-satellite was successfully launched from the Russian Baikonur Cosmodrome on July 10, 1998. Chris Jackson, G7UPN, says TMSAT-1 commissioning has largely been completed and the satellite is in very good shape. Jackson and his team are presently concentrating on testing and calibration of TMSAT-1's multispectral imaging system, reporting a number of very good image sets have been downloaded from the satellite. The satellite is expected to be available for general amateur use shortly.

The TechSat-1B micro-satellite was successfully launched from the Russian Baikonur Cosmodrome on July 10, 1998. The satellite is expected to be available for general amateur use shortly.
The satellite does not have a continuous beacon, but does transmit a 9600-baud burst every 30 seconds (for about 3 seconds in length), currently on 435.225 MHz.
The TechSat team has also constructed a home page about the TechSat bird, and promise they will add more information in the next few weeks. To view the site, point your web browser to:
