OSCAR SKN '98 Best Fist

Ray Soifer, W2RS, AMSAT-NA VP of International Affairs wishes to thank all who participated in AMSAT-NA's OSCAR SKN '98. Although activity was down from prior years due to the loss of RS-10, the temporary loss of Mode K on RS-12 and the unfavorable position of AO-10, a good time was had by those who took part.

Once again our first-place winner was Rusty, NM1K, who received five separate nominations. Two more 1998 winners also had been nominated in previous years: G3RWL and W1NU. Joining the winners' circle for the first time in 1998 were AG2R, K4IPH and VE5SWL. Heartiest congratulations to all.

Change on 75 Meter AMSAT Net

After eight years of exemplary service as NCS of the East Coast 75 meter AMSAT Net, Ron Long, W8GUS, is retiring to pursue other activities. He will continue to assist the new NCS when possible and will continue to support AMSAT in all of the other ways he has in the past. We all owe Ron a big vote of thanks for all of his past efforts and wish him success in his future endeavors.

Ron has groomed his successor, Al Tribble, W3STW, well. Al has been serving as Assistant NCS for some time now. Let's all welcome Al to this position and support him with lots of "check-ins" to the East Coast 75 meter AMSAT Net. As a reminder, this net meets on or about 3.840 MHz each Tuesday evening at 2100 Eastern time. It is followed at 2100 Central time by the Mid-America AMSAT Net, and at 2000 Pacific time by the West Coast AMSAT Net.

To join the ranks of AMSAT HF Net Control Stations, please contact Keith Pugh, W5IU, AMSAT-NA VP of Operations and express your interest. Keith can be reached by e-mail at:

AMSAT Net from P3D Lab

The weekly 20 meter International AMSAT Net will be hosted by Keith Pugh, W5IU, AMSAT-NA VP of Operations, from the AMSAT P3D Integration Lab in Orlando, FL, on Sunday, February 15, 1998. This net meets on or about 14.282 MHz at 1800 UTC for the "pre-net warm-up" followed by the ANS Bulletin Session at 1900 UTC. Wray Dudley, W8GQW, in Tubac, AZ, and Jack Butler, KB7UZ, in Great Falls, MT, will assist during the "pre-net warm-up."

As a special experiment in conjunction with the new Sunspot Cycle, Wray will simultaneously read the ANS Bulletins on 15 meters at the old frequency of 21.280 MHz. Depending upon the success of this experiment, the 15 meter AMSAT Net may be re-activated on a regular basis.

Please check in with the AMSAT Net during this "special edition" for an up-to-date report on the P3D Satellite and on a regular basis to keep up with all of the news about the Amateur Radio Satellite Program.

Other activities in Orlando on the 13-15 Feb. weekend include the ARRL-AMSAT Satellite Workshop on 13 Feb. and the Orlando HamCation for the whole weekend.

Antarctic Trip a Success

Ronald Ross, KE6JAB, reports that his trip to the Antarctic was a success and his portable satellite station a huge success.

Ronald's station (at 80S/81W) consisted of 2 eggbeaters on 7-foot bamboo poles 20 feet apart, on each side of our tent, a 70 cm SSB preamp, an IC-821, a KPC9612 and a laptop. I had to take a sealed lead acid battery, 12V 18AHr, but loaned a solar panel from the Cessna pilot. KE6JAB sent 70 messages of which 16 were JPEG images, using initially UO-22 and then KO-25 also. Those messages and images were posted on his website, which got over 700 hits during the operating period.

Three people contributed greatly to the success, Roy Welch W0SL, Jerry Smyth N8ULU, they downloaded from the birds for KE6JAB, and his longtime friend Ed Anderson KE6IZN, who did the web work. Ronald wishes to thank the many other people on the AMSAT-BB list who answered his technical questions months ago.

For all of his passes, KE6JAB was the only one working the birds over the pole, except each morning ZX0ECF, LW5DGM. PY30G, XQ7GEE and a few others would be logged in. This was when the bird was working its way down from South America and over the Pole.

Ronald Ross, KE6JAB, states that "The station generated a lot of interest amongst other people at the basecamp, they were amazed at the ability of an amateur "network" to provide such communications on a voluntary basis. Especially when the official communications at the camp were having problems at 2400 baud over Inmarsat. I think AMSAT has great resources in technical knowledge and in its members, and much to be proud of."

The results of Ronald's trip can be viewed at As KE6JAB just got back, he will post more digital images in the coming weeks.

This info is from JARL Web page. It's an official announcement from Fuji command station. Originally in Japanese, translation into English is by Kazu Sakamoto, JJ1WTK.

A memory error was detected in onboard computer system of Fuji-3 (FO-29). Restarting and software reloading is being carried out but is taking a long time due to poor uplink efficiency. The operation sked of FO-29 until the end of January is canceled. The bird will stay in analog mode, mode JA, continuously. A new operation schedule for February will be announced on January 26th or later.

AO-10's signals are improving and are quite strong even at apogee, except for periods of deep QSB, which can be largely corrected by changing antenna polarization. These findings suggest strongly that AO-10 has switched itself to its hi-gain antennas. There is probably a component of Z-axis wobble accounting for the QSB. As illumination has improved, the FM'ing heard earlier appears to have disappeared. The switch to hi-gains would also explain the often poor signals near perigee when the squint angle is particularly bad.

AO-10 is currently experiencing long (90 minute) solar eclipses with onset after apogee. The MA of onset will continue to increase and the length of the eclipse will continue to decrease until the period ends on February 23rd.

AO-10's apogee has moved into the northern hemisphere (ArgP > 180). Apogee will continue to rise higher to the north for the rest of 1998, peaking at ArgP = 270 in December.

I have updated my web page to include discussions of the above and updated, smoothed Keplerian elements.

[ANS thanks Stacey Mills, W4SM, for this update on AO-10.]

OZ1MY reports, "AO-10 seems to improve every day. I had very good signals after the eclipse today (29-1-1998). The fading is still very deep - but recovery is faster than 14 days ago. The eclipses last for approximately 1r hours now. Had my first QSO with 9V1UV - and a small talk with VR2XMT, Charlie, who celebrated Chinese New Year. Most of the time I ran 25 W to the old faithful 16-turn helix (G3RUH design) - with that the downlink was at 55 most of the time. The range was approximately 25,000 km at the start - down to 15,000 km when the bed jumped at me.

Using W4SM's ALON/ALAT I would say that the squint angle at the start was about 90 degrees - going up to 140 degrees at the end. Signals were best with 90 degrees."

OSCAR-11 REPORT 14 January 1998

During the period 16 December, 1997 to January 14, 1998 the satellite has continued to provide good signals on its 145.826 MHz beacon, although occasional interference has been caused by DOVE, which transmits near this frequency.

Interest in the mode-S beacon continues, as stations prepare for P3D. Four reports have been received. Stacey W4SM reported S3-4 signals compared to an S2 noise level. Dove was S8. He uses a two foot diameter G3RUH dish with 2.5t helix, and SSB converter. Manfred XE1ZBO in Mexico City has received strong signals, using a Conifer partial dish, and SSB converter. Mark KE7NS reports good signals, above an S7 noise level. He uses a 21 element beam, Aircom pre-amp, and Drake converter. Many thanks for those reports.

The telemetry is nominal. Internal temperatures have continued to fall, and at the present time are 6.4C and 4.2C for battery and telemetry electronics respectively. This fall in temperature is due to increasing solar eclipse times, which are expected to reach a maximum in early February.

Two WOD surveys have been transmitted during the period. Both are of channels 10, 20, 30, 40 (+Y, -X, +X array currents, array voltage), and are dated 14 December, and 06 January respectively. They show the effect of solar eclipses, on array currents, and voltage.

The new format AMSAT-UK bulletin, No. 114, is now being transmitted. This contains details of amateur satellite frequencies and modes of operation. It is intended to be a 'fixed' message, which won't become out of date too quickly. It may however be changed from time to time, possibly at monthly or greater intervals. Regular listeners will note that the new bulletin makes a different sound compared to previous bulletins, rather like a new form of binary data. This is because the bulletin contains regularly placed blocks of spaces, instead of random text characters.

The operating schedule is unchanged.

Transmission Duration
ASCII status 210 seconds
ASCII bulletin 60 seconds
Binary SEU 30 seconds
ASCII TLM 90 seconds
ASCII WOD 120 seconds
ASCII bulletin 60 seconds
Binary Eng 30 seconds

There are also additional status blocks after each bulletin is transmitted, and between ASCII TLM and WOD.

The mode-S beacon is ON, transmitting an unmodulated carrier, but telemetry indicates that it has partially failed, and delivering half power. This beacon is a useful test source for those testing mode-S converters, prior to the launch of P3-D. It is considerably weaker than DOVE, which should be used for initial testing. Any reports of reception on 2401 MHz would be most welcome. Please e-mail reception reports to

The 435.025 MHz beacon is normally OFF. However it can sometimes be heard when the satellite is being commanded by ground control, (i.e. within range of Guildford, Surrey, UK). When the 435 beacon is transmitting, the 145 beacon is normally OFF. The data transmitted is mainly binary.

OSCAR-11 users are welcome to visit the G3CWV web site. It contains some software for capturing data, and decoding ASCII telemetry and WOD. There is an archive of raw data (mainly WOD) for analysis, which is continually being expanded, as new data is captured. The URL is
