Straight Key Night on OSCAR

Wondering just how to welcome the new millennium? Ray, W2RS, has one suggestion - SKN!

Ray invites satellite operators to participate in the 28th annual Y2K edition of Straight Key Night on OSCAR, sponsored by AMSAT-NA. The event is open to all radio amateurs worldwide.

As always, there are no rules, no scoring and no need to send in a log at the end of the event. W2RS tells ANS that SKN is simple - all operators need to do is operate using the continuous wave (CW) mode of transmission (with a hand key!) on any OSCAR satellite, or the moon (OSCAR-Zero), between 00:00 and 23:59 UTC on 1-January-2000.

All participants are encouraged to nominate the operator with the best fist among those they heard or worked.

Please send your nomination to W2RS:

via e-mail: w2rs@amsat.org
via packet radio: W2RS @ WA2SNA.NJ.USA.NA (or)
W2RS @ GB7HSN.#32.GBR.EU

Ray also tells ANS that his listed callbook address is correct.

Best Fist nominees will be featured in an AMSAT News Service bulletin in early February and in the next available issue of the AMSAT-NA Journal following the contest end.

League Opposes 2.4 GHz Video Proposal

The ARRL has asked the FCC to deny an experimental license application by Los Angeles County, California, to develop a public safety video system on the 2.4 GHz band. The frequencies in question could pose potential harm to Amateur Radio satellite communication channels, as well as terrestrial ground transmission and reception.

In its objection, filed September 23rd with the FCC, the League called the LA County proposal a "foot in the door" toward gaining a permanent berth in the 2.4 GHz band. "It is obvious from the experimental proposal that the County wishes to construct the entire system and then simply stay there," the League said. The ARRL said the FCC should authorize nothing more than a single 10-MHz video channel for a single transmitter aboard a single helicopter, to allow interference studies to be conducted.

The decision to grant the proposed experimental license is up to the FCC Office of Engineering and Technology's Experimental Licensing Division. In making its decision, however, the OET is expected to consult with the Wireless Telecommunications Bureau, which oversees Amateur Radio and the other affected services on 2.4 GHz.

Stay tuned to the ARRL and ANS for more information as this story unfolds.

Mars Orbiter Missing

Mission managers at the Jet Propulsion Laboratory know that the Mars Climate Orbiter (MCO) reached the red planet, but unfortunately, it didn't last long.

The spacecraft fired a braking rocket last Thursday morning and initial telemetry indicated that 'all was well' as the orbiter passed behind Mars and out of touch with Earth. However, MCO's radio beacon was not received when it should have reappeared about 20 minutes later.

According to Project Manager Richard Cook, data obtained several hours before arrival indicates that the spacecraft was going to pass only 30 miles from the Martian surface, much lower than the planned approach. Initial speculation is that the craft seriously overheated as it passed through the planet's upper atmosphere and perhaps broke apart from aerodynamic stress.

An investigation continues to determine how the spacecraft got so far off course as it approached Mars.

MCO was to serve as the telecommunications relay for the Mars Polar Lander (which will arrive at the red planet on December 3rd). The Lander is scheduled to perform a soft touch down near the planet's south pole. Fortunately, MPL carries a radio for direct communication with Earth (though at a slower data rate).

The Mars Global Surveyor, which has been orbiting Mars for two years, can also serve as a data relay.

KO-23 and IO-26 Status Update

With the sad news of the loss of the Mars Climate Orbiter, ANS is pleased to report on the recovery of two amateur radio satellites: KITSAT (KO-23) and ITAMSAT (IO-26).

IO-26

Nearing its 6th year in orbit, IO-26 ground controllers IK2XRO and IW2EGC have reloaded the high level code and turned on the IO-26 435.822 MHz PSK transmitter. Analysis of returned telemetry shows a healthy satellite with a fully charged battery (after 4 months of stand-by MBL mode).

A Whole Orbit Data (WOD) survey is currently underway, collecting data on array current, battery voltage and onboard temperature. Following the WOD collection, control stations plan to activate the digipeater function and experiment using the APRS system.

KO-23

ANS has learned from KyungHee Kim, HL0ENJ, that satellite downlink telemetry is showing two of KO-23's ten battery cells to be very unstable. However, ground control stations have been successfully operating KO-23 with only minimum systems. Attitude control has been lost and power failures are still being experienced. Even with these problems, operation of the BBS has been recently achieved.

Jim Weisenberger, AA7KC, reports KO-23 returned to service on September 21st. "The satellite was missed by many users while it was out of service," said AA7KC, adding, "congratulations to the control team for correcting the operational problems."

Stay tuned to ANS for further updates.

PANSAT PO-34

Downlink frequency not established.
The satellite is not currently available for uplink transmissions.

PANSAT, developed by the Naval Postgraduate School, was launched from the shuttle Discovery. PANSAT spread-spectrum digital transponders will be available to amateur radio operators in the near future along with software to utilize this technology. The PO-34 command station is located in Monterey, California.

Dan Sakoda, KD6DRA, PANSAT Project Manager recommends 'The ARRL Spread Spectrum Sourcebook' as a good place to start in understanding the spread-spectrum scheme.

The SunSat package includes 1200 and 9600 baud digital store-and-forward capability and a voice 'parrot' repeater system that will be used primarily for educational demonstrations. The satellite has two VHF and two UHF transmit-receive systems.

SunSat has been in mode-J recently. Bruce, KK5DO, has recorded several mode-J SO-35 passes in RealAudio, check out http://www.amsatnet.com to listen.

UoSAT-12 UO-36

Downlink 437.025, 437.400 MHz

UoSAT-12 was successfully launched on April 21, 1999 from the Russian Baikonur Cosmodrome. UO-36 carries a number of imaging payloads, digital store-and-forward communications and mode L/S transponders.

The satellite is not currently available for general uplink transmissions.

UO-36 has been transmitting 9600-baud FSK telemetry framed in a VLSI format using a downlink frequency of 437.400 MHz. Chris, G7UPN, reports UO-36 is also transmitting on 437.025 MHz at a baud rate of 38,400 (38k4). G7UPN also tells ANS that UO-36 is severely power limited and Chris is working on a new protocol to allow the downlink to only be switched on over active ground stations. "Once we get this going, UO-36 will be running the 38k4 downlink, and will be available when spacecraft resources (primarily power) permit," said G7UPN. Presently the BBS is still closed.

S-band high speed downlink commissioning continues at rates between 128kb/s and 1Mb/s. The S-band downlink frequency has not been announced.

The VK5HI TMSAT viewer software is available on the AMSAT-NA web site at ftp://ftp.amsat.org/amsat/software/win32/display/ccddsp97-119.zip

Further information on UO-36 is available from: http://www.sstl.co.uk/

The following satellites are in orbit but are non-operational at this time:

Mir Space Station

Ham radio activity aboard the Mir space station came to a close on August 28, 1999 as the crew returned to Earth, leaving the station unmanned. Mir is in a stable orbit with only essential systems running. All amateur radio activities have ceased. Currently, the station is being prepared for re-entry sometime in the first quarter of 2000. However, the final fate of the space station has not been formally announced. Stay tuned to ANS for further developments.
