Paul Wilson, W4HHK, a Silent Key

The ARRL reported that VHF-UHF pioneer Paul Wilson, W4HHK, of Collierville, Tennessee, died November 29th at age 75. Former AMSAT-NA President Bill Tynan, W3XO, was saddened by the news, telling ANS that "Paul was a very good friend and a great VHF'er."   Tom Clark, W3IWI, also praised Wilson, adding, "I was very sad to learn of the death of my old friend and personal hero, Paul was truly a UHF pioneer and will be missed." ARRL Vice President Joel Harrison, W5ZN, also talked about W4HHK; "Paul's life should inspire every amateur to strive to always try something new in Amateur Radio, regardless of age or health, he has definitely been an example for me."

Wilson was a stalwart in the 144-MHz and Microwave Standings and remained active right up until his health deteriorated earlier this year. In early July he completed his VUCC on 10 GHz and celebrated his 75th birthday by making his first contact on 24 GHz.

Paul Wilson got his ham ticket in 1941 at the age of 16. During the 1950s, he got involved in meteor scatter propagation, and in 1954 W4HHK and Tommy Thomas, W2UK, sent and received reports over a 950-mile path -- both winning an ARRL Technical Merit Award for their efforts. Wilson then took on the challenge of EME, becoming among the first to make 70-cm EME contacts in July 1965. In 1970, W4HHK claimed a new record -- the first 2304-MHz EME contact.

Equally amazing were his successful efforts to monitor the Apollo command module on 2.2 GHz as the astronauts orbited the moon. He received a NASA confirmation of his reports in the form of a photograph signed by all the astronauts on the mission!

Wilson is survived by his wife of 54 years (who is W4UDQ) and his son Steven, N4HHK. A service was held December 2nd in Collierville.

[ANS extends the sympathy of the entire AMSAT organization to the entire Wilson family at this difficult time]

Satellite Launch Delayed

Technical problems at Vandenberg Air Force base has caused a launch delay for several new satellites, including JAWSAT, OPAL, STENSAT and ASUSAT-1. Assi Friedman, KK7KX/4X1KX, the Deputy Program Manager of the ASUSAT program told ANS "it looks like we will not have any new satellites in time for Christmas, adding, "we were notified that due to technical difficulties our launch is delayed to January 22nd."

The launch was to have taken place over the weekend.

"We will keep everyone notified of any new announcements," promised KK7KX. A web page with initial information, a telemetry configuration file and status updates will also be completed shortly. Photos of the rocket are available at

New AMSAT-NA Journal Service

AMSAT Journal Editor Russ Tillman, K5NRK, invites Internet users to try out a new service soon to be featured on the AMSAT-NA web page -- a listing of URL's used in Journal articles.

"Tired of trying to correctly enter a URL address from an article that appeared in the AMSAT Journal?" asked K5NRK. "So was AMSAT-NA member, Jeff Davis, N9AVG, who suggested posting URL's and e-mail address on the AMSAT-NA web site." Once connected to the AMSAT-NA web page, Journal readers will be able to easily go to an article URL without having to retype the address into their favorite web browser.

The service will start with the November/December 1999 issue, scheduled for delivery in mid-December -- and speaking of this issue, K5NRK gave ANS a sneak preview of just some of the upcoming Journal articles, (including):

AMSAT-NA membership includes a subscription to the AMSAT-NA Journal.

AO-27 uses a method called Timed Eclipse Power Regulation (TEPR) to regulate the on-board batteries. In simple terms, TEPR times how long the satellite has been in the eclipse (or in the sun) and decides what subsystems to turn on or off.

Chuck, KM4NZ, reset the TEPR states on AO-27 (on October 11).

TEPR 4 is 22    TEPR 5 is 58

Mike, KF4FDJ, recently operated on AO-27 from the Tampa hamfest.

Uplink/downlink frequencies have not been 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.

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

SunSat SO-35

Semi-operational. SunSat has been in mode-B using an uplink of 436.291 MHz (+/- Doppler) and a 145.825 MHz downlink.

SunSat was launched February 23, 1999 aboard a Delta II rocket from Vandenberg Air Force Base in California. SunSat stands for Stellenbosch University Satellite and takes it name from the South African university whose students constructed the payload.

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.

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.

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

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 (at times) testing on 437.025 MHz at a baud rate of 38,400 (38k4).

Presently the BBS is still closed.

The VK5HI TMSAT viewer software is available on the AMSAT-NA web site at

TechSat-1B GO-32

Downlink 435.225 MHz
HDLC telemetry framed so a TNC in KISS mode will decode it

Updated status. Shlomo, 4X1AS, tells ANS that efforts are underway to bring GO-32 on line. According to Dr. Fred Ortenberg of the Asher Space Research Institute in Haifa, "the TechSat control team is about to finish its Amateur Radio BBS package tests. The next stage is to add beacon messages about the satellite's housekeeping status."

Stay tuned to ANS for further information.

The TechSat-1B micro-satellite was successfully launched from the Russian Baikonur Cosmodrome on July 10, 1998.

Last reported, 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 constructed a home page about TechSat. To view the site, point your web browser to:

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.
