Dr. A. C. Gee, G2UK, SK

Dr. A. C. Gee. MRCS. LRCP. DPH. G2UK. SK

It is with great sadness that we report the death of the former Chairman of AMSAT-UK. Dr. A. C. Gee died in a hospital at Lowestoft, Suffolk, England during the early hours of 19th May 1997 following complications arising from an earlier hip operation. He was 84.

"Doc" Gee, as he was referred to by many friends, was an AMSAT-UK member from the formation of the Organization and became its Chairman in 1979. He resigned from that office in 1992 due to ill heath. Ron Broadbent, G3AAJ, notes that he was a friend for over thirty years, and certainly a considered "wise head" with whom he could discuss problems on most subjects. He was, up to three weeks prior to his death, operating through RS satellites. He will be remembered as the writer of the Satellite column in "Radio Communications" for several years.

Broadbent says that Arthur Gee was also most interested in the new P3D satellite, and any information about that satellite he could get was received with great interest.

His interests were far ranging even outside amateur radio. G2UK was a skilled model-maker of sailing ships, a Founding member and Commodore of the Lowestoft Cruising Club, Member of Royal Norfolk and Suffolk Yacht Club, and a member of Waveney and Oulton Broad Yacht Clubs. Gee was also an amateur astronomer and member of Norwich Astronomical Society and editor of it's newsletter. He was also an enthusiastic steam-boat owner, one time radio operator/medic on an expedition to Orland Island off the coast of Sweden to record an eclipse of the Sun.

His G2UK amateur radio callsign dates back to 1935.

During the mid 1930s, Arthur Gee was a member of the Royal Naval Wireless Auxiliary Reserve, which led to his life-long interest in amateur radio. He was a member of the London Wireless Club, now the RSGB the BARTG, RAYNET and ISWL. and Co-Director of Data Publications a now defunct Radio Constructor magazine. He was also a Medical Officer of Health to the old Suffolk Counties Hospital Area. G2UK was well liked and a respected citizen of Oulton Broad, where he had lived for over fifty years. He will be missed by his friends and neighbors as well as many members of the amateur radio fraternity worldwide.

Dr. Gee is survived by his wife Marjory, son Richard, and daughter Marion.

SunSat News

AMSAT member Phil Chien KC4YER attended a recent press conference regarding the upcoming Delta 243 / Thor II launch. During the press conference, Phil asked about the status of the launch of the USAF ARGOS satellite. That launch is to feature two secondary payloads, the Danish Orsted, and the South African SunSat. SunSat includes amateur transponders and some pretty interesting experiments, Phil notes.

He was told that a firm launch date in not yet set, but that it certainly would not be this year. The indication was the satellite wasn't ready yet, presumably the primary payload. Chien notes that the McDonnell Douglas Delta II and III manifest lists their civilian (e.g. NASA) and commercial launches. He believes that there are plans to put the manifest on their home page, but it wasn't up when he looked last week.

The manifest indicates a 3rd Quarter 1998 launch for Deep Space 1, which Phil believes is the New Millenium launch which is to carry SedSat as a secondary payload.

3C0DX DXpedition Postponed

It has been regretfully announced that the Dxpedition to Annobon Island has had to be postponed until next October. It is reported that, at the last moment, Guinea's authorities turned down the group's intention to operate an amateur radio station, including satellite equipment, from the island as 3C0DX.

Everything was reported ready, including materials, equipment, 13 operators, airline tickets, medical insurance, enough money for the big expedition. But, three days prior to departure, authorities refused to allow 11 of the 13 operators to go. The group plans to try again next October and hopes for better luck.

DL0ART/am - 5th Launch

After quite a long break, the DL0ART says, "we did it again... the 5th launch of our balloon DL0ART/am was on 18-May-1997." The main feature of this flight was the transponder (mode B), which worked quite nice, and many hams took the chance to use it.

More information about DL0ART/am (pictures!) can be found at:
Internet: http://buene.muenster.de/darc/artob/homebale.htm

Balloon launch 18-May-1997
Launch# 5
Launch date18-May-1997
Launch time1214 UTC
Launch site Nienberge near Muenster, NW Germany, JO32sa

Those who heard the DL0ART/am signals, may send QSLs by mail, the Internet, or through the QSL bureau. All will be answered by the DL0ART/am team. Any suggestion or response is always welcome!

The DL0ART/am team hopes that all enjoyed this experiment, as well as the previous flights. The team regrets that they must terminate the project at this time. This is due to a substantial lack of manpower and financial resources for things like insurance, which runs DM 500, or 300 U.S. Dollars.

Mir

(Uplink 145.2 MHz FM Downlink 145.8 MHz FM)

Note, the above split is used for both packet and voice operation. ANS has received information that states that all amateur activity from Mir has been suspended until further notice.

SAFEX, Mir 70cm Repeater

(Uplink 435.750 MHz FM, Downlink 437.950 MHz FM, Subaudible tone 141.3 Hz)

ANS has received information that states that all amateur activity from Mir has been suspended until further notice.

RS-10

(Uplink 145.865-145.905 MHz CW/SSB, Downlink 29.36-29.4 MHz CW/SSB)

RS-10 is operational.

RS-12

(Uplink 21.21-21.25 MHz CW/SSB, Downlink 29.41-29.45 MHz or 145.91-145.95 Mhz CW/SSB)

Signals on RS-12 in North America during May and June (almost exclusively daylight passes) are weakened by increased ionospheric activity which is keeping 15m active during the daylight hours. This makes it especially important for the 'old timers' to warn the newcomers on RS-12 to set their uplink frequency and leave it alone to prevent sweeping across the 15m band and QRM-ing the terrestrial QSOs in progress.

[ANS thanks Dick Montgomery, N3DV, for this update.]

RS-15

(Uplink 145.858-145.898 MHz CW/SSB, Downlink 29.354-29.394 MHz CW/SSB)

Be aware that RS-15 has battery charging problems. When the satellite is in the dark it has low output power.

[ANS thanks Geoff Perry for this report.]

(Hint: If SSB doesn't work for you, try CW. CW is very easy to hear on the downlink!)

RS-16

RS-16's 70 cm, 435.504 MHz beacon may not be operational. Jess Burmeister, KB0VUU, reports not hearing the 70 cm beacons during two passes of the bird on May 25th.

RS16 had no beacons active on 10 meters or 2 meters. At this time the transponder is not operational.

[ANS thanks Jim, KC7RCY, Jess, KB0VUU, Chuck, KI0AG, and Mike, N1JEZ.]

FO-20

(Uplink 145.9-146.0 MHz CW/LSB, Downlink 435.8-435.9 MHz CW/USB)

Operating normally. Strong downlink signal. Very busy during passes over North America. Please remember to adjust the higher frequency for doppler when the bird is in analog, JA, mode. This means adjust the 70 cm frequency, the downlink, for doppler shift. You do not have to adjust the 2 meter frequency, the uplink, for doppler.

KO-23

(Uplink 145.85, 145.9 MHz FM, Downlink 435.175 MHz FM, 9600 Baud FSK.)

KO-23 operating normally.

KO-25

(Uplink 145.980 MHz FM, Downlink 436.5 MHz FM, 9600 Baud FSK.)

KO-25 operating normally.

[ANS thanks Jim Weisenberger, AA7KC, for his reports on KO-25 and KO-23.]

AO-27

(Uplink 145.85 MHz FM, Downlink: 436.792 MHz FM (As of April 1, 1997) )

Operating normally. The satellite is very busy over North America. Gregg, N0ZHE, suggests that you should try QRP on AO-27. Gregg states that weekdays are the best for QRP operation because of the lighter traffic on the bird. N0ZHE operates with a home made arrow antenna and an Alinco dual band HT.

[ANS thanks Greg Wycoff, N0ZHE, for this information.]

Current AO-27 schedule information can be found at www.umbra.com.

  Tepr 4 = 32 counts   16 Minutes
  Tepr 5 = 66 counts   18 Minutes

AO-27 will turn on every pass 16 minutes after entering the sun and will stay on for 18 minutes. This corrects the early shut off that has been going on for the past few weeks.

[ANS thanks Michael Wyrick, N4USI, AO-27 Control-op, and Miguel A. Menéndez, EA1BCU, for this update.]

FO-29

Voice/CW

(Uplink 145.9-146.0 MHz CW/LSB, Downlink 435.8-435.9 MHz CW/USB)

Digital

(Uplink 145.85, 145.87, 145.910 MHz FM, Downlink 435.910 MHz FM 9600 baud BPSK)

Please remember to adjust the higher frequency for doppler when the bird is in analog, JA, mode. This means adjust the 70 cm frequency, the downlink, for doppler shift. You do not have to adjust the 2 meter frequency, the uplink, for doppler.

The latest FO-29 Schedule can be found at http://www.kt.rim.or.jp/~jr1nvu/eindex.html.

AO-10

(Uplink 435.030-435.18 MHz CW/LSB, Downlink 145.975-145.825 MHz CW/USB)

Stacey Mills reports that AO-10 will be in sleep mode for the next few weeks. The transponder and beacon do not have enough power to operate.

[ANS thanks Stacey Mills, W4SM, for this report.]

OSCAR-11

(Downlink 145.825 MHz FM, 1200 baud PSK. Beacon 2401.500 MHz.)

Operating normally.

Telemetry nominal. The battery voltage has recently improved to around 13.9 volts, and the internal temperatures have continued to fall, due to solar eclipses. The battery temperature is now 4 degrees C, or 18 degree below the full sunlight condition.

The operating schedule is unchanged.
