- -----------------
- Here is the latest operating schedule for FUJI-OSCAR-12:
-
- Date Mode Operating Period
- --------+------+------------------
- 05Nov89 | JD | 0948 - 1151 UTC
- 18Nov89 | JA | 0532 - 1142 UTC

- * OSCAR-13 NEWS *
- -----------------
- Peter (DB2OS) reports that after reloading the onboard computer with IPS and
- the operational software, AO-13 appears to be working properly. Transponder
- operation was resumed on 13Oct89. All AO-13 users are asked to be alert to
- the possibility of another IHU crash. If the general VHF beacon is found to
- be sending an unmodulated carrier or if transponder modes are changing at
- radically different MA "counts" from the published operating schedule, then
- users are asked to cease AO-13 operations.
-
- DB2OS and others have made another attempt to get RUDAK "on-line". RUDAK was
- designed to be a packet radio digipeater, but shortly after launch, the RUDAK
- "bootstrap" loader would not load the necessary software from ROM. The problem
- appears to be a defective PROM. A certain measure of success was recently
- achieved when the "bootstrap" loader started loading software from the ground.
- Although it was still not possible to load all the necessary software, the
- fact that the RUDAK "bootstrap" loader did work to a limited degree does leave
- some room for hope.
-
- Here is the latest AO-13 Operating Schedule:
-
- Mode B : MA 003...160
- Mode JL : MA 160...200
- Mode B : MA 200...240
- OFF : MA 240...003
-
- Note: Mode JL operations may not occur on time due to RUDAK testing.
-
- The Bahn attitude is 208/-3. The omni antennas will be used from MA 240 to 060.
- Mode S operations will begin early this week.
-
-
- * SOLAR FLARE *
- ---------------
- According to the Hiraiso Solar-Terrestrial Research Center, Communications
- Laboratory, Japan, a reddish aurora was observed for about 10 minutes from
- Wakkanai, Hokkaido, Japan at 11:45 UTC on 21Oct89. This same solar disturbance
- blacked-out HF radio communictions world wide.

- * MIR NEWS *
- ------------
- The expected launch of an expansion module to the Mir/Kvant-1 complex on 16Oct
- did not occur. On 11Oct89, TASS reported that this launch had been delayed due
- to an electronics problem with the air lock, or "D" module. Final, pre-launch
- tests showed problems in the scientific instuments on the module, not in the
- control system itself. This air lock system is now set for a mid-November
- launch, while the Technology module (Module T) is set for February 1990.
- The crew members, Cosmonauts Alexander Viktorenko and Alexander Serebrov, will
- maintain their original time table, and return to earth on 19Feb90.

-
- I challenge you to measure the loss through this connector at
- 2 meters or 440. I sure can't and I have some pretty spiffy test
- gear. Sure, I can see the impedance discontinuity on a TDR but it
- does not look much different than a BNC. Besides, impedance bump != power
- loss at low UHF and below.
-
- There's a really good reason why the PL/SO connectors are still around.
- They do the job and they are cheap. The day I can buy a silver-plated,
- teflon insulated N connector for 50 cents is the day I'll swap. Until
- then, the good 'ole UHF connector will work nicely.
-
- Oh what the heck, I must be all screwed up. After all, I use 75 ohm
- CATV hardline in my shack too. That it works just fine with very low
- loss does not affect the "experts" who continue to tell me that it will
- not work. Must be the UHF plugs I use on each end.

- Subject: How to charge Kenwood PB-21H?
-
- I've recently acquired a PB-21H battery for my Kenwood TH41 handheld.
- Does anyone have any idea what I need to charge this battery? I could
- go buy a BC-2 or BC-6, but I could also probably buy something at half
- Kenwood's price, if I knew what was needed. The battery and its packing
- materials give no clue.
-
- The PB-21H is the high-powered battery for the Kenwood TH21-31-41
- series. Output is 7.2V DC (500 mAh).

- When I can't get solder to stick to a PL-259 I use a small triangular
- file to remove the plating from inside the four holes. That usually
- does the trick.

- Subject: Shortwave Listening via C-SPAN
-
- On November 1st, the C-SPAN Audio Network formally begins operation,
- delivering English-language shortwave programming by satellite to all of
- the cable television systems that subscribe to C-SPAN video. (Actually,
- the signals have been available in the transponders of Galaxy III since
- early in September. Cable systems will start utilizing them Nov. 1st.)
-
- C-SPAN Audio 1 is a smorgasbord of US Congressional hearings in the
- afternoon, and shortwave programs in the morning and all evening. Among
- the services initially available are the BBC, R Canada International,
- R Beijing R Japan, R Netherlands, Deutsche Welle and R Prague. Available
- soon will be R France International, R Austria International, and others.
-
- C-SPAN Audio 2 is the BBC World Service - nonstop, 24 hours/day, and with
- studio-quality sound.
-
- If you are a cable subscriber and want your local system to start carrying
- these services as the sound on alphanumeric channels, tell your cable
- operator to contact:
-
- Beth Glatt, Manager
- C-SPAN Audio Network
- Suite 650
- 400 N. Capitol St. NW
- Washington, DC 20001
- (phone 202-737-3220).
-
- If your cable system already carries C-SPAN video, there is NO ADDITIONAL
- CHARGE for these shortwave broadcast feeds, and they are available in the
- same transponders as the video they already receive. All the cable system
- needs is a pair of SCPC (single-channel-per-carrier) demodulators. The
- only condition that C-SPAN imposes is that if a system wants to carry the
- BBC World Service, they must also carry Audio 1.
-
- This is potentially one of the best and easiest ways to expose millions of
- Americans to shortwave listening. Even if YOU have access directly
- yourself, think of all those who don't, and how much it might benefit them.
- Note that all the C-SPAN relays are real-time - no delays. And more feeds
- are planned in the future - in foreign languages (Japanese, Chinese,
- Spanish, French, etc.) - as well as English from other regions - Africa,
- Southeast Asia, etc.
-
- C-SPAN is also preparing a tape that explains what shortwave broadcasting
- is, to run every day on their audio channels. Let's help them get the word
- out. This project is bound to stimulate much wider interest in SWLing,
- and increase the American public's understanding of foreign points of view.

-
- This sounds wonderful, but I'm not sure I understand just where
- listeners can expect to find these broadcasts. On the SAP signal of
- the two CSPAN cable channels? Somewhere else in the TV portion of the
- cable signal? Somewhere on the FM-band portion of the cable signal?
- Can you provide more details, or will this vary which each cable
- company?
