- IARU Appoints Satellite Adviser
-
- In a news release dated 26-SEP-94, the International Amateur Radio Union
- (IARU) announced that it has appointed Hans van de Groenendaal (ZS5AKV) to
- the newly created post of IARU Satellite Adviser. According to the IARU
- release, the principle task of this position will be to keep the IARU
- Administrative Council informed on all technical and operational aspects of
- the Amateur Radio Satellite Service in order to enable the Council to adopt
- appropriate policies to advance the interest of the Amateur Satellite Service
- before the International Telecommunication Union (ITU) and regional telecom-
- munications agencies.
-
- The IARU release noted that ZS5AKV, as past President of Southern African
- AMSAT and an Executive Committee member of IARU Region 1, brings many years
- of satellite related experience to this appointment. The IARU release
- further noted that the appointment is a direct result of recommendations
- made to the IARU Administrative Council by the IARU Ad Hoc Satellite
- Advisory Committee which took up the interim report at the recently com-
- pleted IARU Administrative Committee meeting in Singapore. The IARU
- release commented that this action is "tangible proof" of IARU's interest
- and involvement in the Amateur Satellite Service.
-
- The release continued by citing IARU's many year role in protecting the
- Amateur Satellite Service, in particular its work during the 1979 World
- Administrative Radio Conference which led to most of the present Amateur
- Satellite Service frequency allocations.
-
- The IARU release also stated that the "exponential development of new tech-
- nologies and ever increasing complexity of the Regulatory Agencies, the IARU
- Administrative Council deemed it necessary to involve itself closer with the
- Amateur Satellite Service in order to represent it effectively on a coordin-
- ated world-wide basis while cementing its relationship with the AMSAT and
- other Amateur Radio Satellite groups."
-
- In the release the IARU said that in his new capacity and by the powers
- delegated to him by the IARU, ZS5AKV will have the task of appointing
- someone to the post of IARU Satellite Frequency Coordinator.
-
- The IARU said that ZS5AKV is now soliciting nominations for volunteers
- willing to serve the function of IARU Satellite Frequency Coordinator.
- Such nominations should be sent to him by FAX at +27-31-765-6456 or via
- INTERNET at amsat@uctvax.uct.ac.za before 31-OCT-94. Hans said that each
- nomination should include a comprehensive summary of the nominee's background
- and qualifications. He stated that it is his intention to discuss the various
- nominations with major AMSAT groups in order to seek their recommendations.
- He underscored the importance of finding the right person to be appointed
- to this very important job.

- The battery charge state is of paramount importance during the eclipse
- seasons. As always the command team may have to have to make temporary

- FO-20: FO-20 has been switched back into the analog mode as of 14:30 UTC
- 28-SEP-94. The command station announced that "mailbox software ran away"
- and there is a malfunction known as UVC (Under Voltage Control) has been

- MIR: German Astronaut Dr. Ulf Merbold will be QRV aboard the space station
- MIR signing DP3MIR during the ESA EUROMIR 94 mission starting 03-OCT-1994.
- In order to give actual information regarding the mission to as many radio
- amateurs and SWLs as possible, he will use the digital voice memory of MIR's
- HAM RADIO rig designed and built by Thomas Kieselbach (DL2MDE). Thomas made
- an arrangement with Ulf Merbold, DP3MIR, to load actual spoken reports into
- the digital memory frequently, as time permits however, probably every 2-3
- days. The reports in English and German will then be retransmitted auto-
- matically during the consecutive orbits at 145.550 Mhz (FM) in regular time
- intervals. Ulf Merbold will stay aboard MIR for 30 days. [DF5DP]
-
- RS-10: WA6ARA reports that RS-10 is operating well with a good mix of SSB
- and CW. Orbit times are great for late evenings to the East and with early
- evening passes to the West. [WA6ARA]
-
- RS-12: WA6ARA reports that Mode-K is alive and very well. RS-12 is just
- starting to appear in late evenings. Over the next month the passes will
- be great for evening passes. [WA6ARA]
-
- The AMSAT NEWS Service (ANS) is looking for volunteers to contribute weekly
- OSCAR status reports. If you have a favorite OSCAR which you work on a
- regular basis and would like to contribute to this bulletin, please send
- your observations to WD0HHU at his CompuServe address of 70524,2272, on
- INTERNET at wd0hhu@amsat.org, or to his local packet BBS in the Denver, CO

- I started out in Satellites (RS 10) with a Yaesu FT101E, a FT221
- 2 meter all mode and a Hamtronics Downconverter to bring 440 to 10m
- to the Yaesu. The converter was relatively easy to construct, and

- September 20th but with little activity from him. Several in the
- Southeastern Cluster Group worked him around 0330Z on October 1st on
- 7028 khz. His signal was reported to be good, and he called several

- in Africa and unable to join them this year. To receive a multi-colored
- QSL card, QSL via ON4UN.
-
- PACIFIC DXPEDITION/HOLIDAY DELAYED AGAIN. Masa, JE1DXC (A35XC), is still
- having problems with airplane reservations which continues to delay his
- departure for 3D2, T30, and T2. He plans to be active from the Pacific
- for the CQWW DX SSB Contest.
-
- SV/A, MT. ATHOS. The Tokyo Packet Cluster reports Monk Apollo, SV2ASP/A

- following QSL route for VP8CQJ operation: Jon Carp (PLEASE NOTE: Jon -
- NOT John), 9 Hawthorn Road, Gatley, SK8 4LX UK. Jon requests cards be
- sent DIRECT ONLY as no envelopes will be lodged with a bureau. Cards
- submitted without a green stamp or IRCs will be answered via the bureau.
-
- XF3, COZUMEL ISLAND, MEXICO. Gene, K7DBV, will operate as XF3/K7DBV from
- Cozumel Island (IOTA NA-090) from November 22-29. He plans to be active
- in the CQWW DX CW Contest using low power to a wire antenna on all bands
- (80-10 meters), primarily CW (with some SSB outside contest). Also, check

- Chesnokov UA3AB, Igor "Harry" Booklan RA3AUU, Gabriel Valdez XE2Z, Motoaki
- Saito JH1EDB, Ed Kritsky NT2X/RV7AA, Pepe Lozano XE2MX and Alfonso Belmar
- XE1ILH. This group feels they are the first to ever put on a contest effort

- I'd love to see a 6m AM net also. Not because I have an AM only
- rig, but because the 6m band can use the activity. Many of the
- contemporary 6m rigs do have the ability to operate AM also (that's
- certainly the case for my TS-690), so maybe someone can get something
- going here and we can get it reported in QST and CQ also.
-
- Gee, I'd also give me a chance to try out my old Gonset converter
- (6m to AM broadcast band) also.
-
- How about something like 50.150 that's 25KHz up from the regular
- SSB calling frequency? Anyway, just an idea.
-
- Let's put some of those old AM rigs to good use.

-
- I tried to get a 6M AM net going here in the Phoenix area a while back but
- couldn't get any interest. My one-owner (me) Heath Sixer is all tuned up and
- ready to go. I can't remember the freq of the xtal but like someone else here
- said...it really doesn't matter much with the Sixer rcvr.
-
- I also have a one-owner (me again) Knight T-60 that supposedly does 6M AM and
- a receiving converter built from the 1963 Handbook for 6M-to-20M that should
- still work. At least it did back then.
-
- All I need is an antenna.
