26th Annual SKN on OSCAR

Amateur radio operators worldwide are cordially invited to join in the 26th annual Straight Key Night on OSCAR, sponsored by AMSAT-NA for ham radio satellite enthusiasts.

According to Ray Soifer, W2RS, it's entirely unofficial with no rules, no scoring and no need to send in a log. Just call CQ SKN in the CW passband segment of any OSCAR satellite from 0000 to 2359 UTC on January 1, 1998, or answer a CQ SKN call from another station. OSCAR Zero (EME) contacts count too.

Of course, all SKN operating must be done with a straight hand key. Those participating are encouraged to nominate someone they worked for recognition as having the "best fist." To send in a "best fist" nomination, please send it to:

e-mail - w2rs@amsat.org

packet radio - W2RS @ WA2SNA or W2RS @ GB7HSN

Regular mail can also be sent to the W2RS callbook address. Those nominated will be featured in a bulletin sent to many of the amateur radio publications and posted via ANS, packet radio and the Internet in early February.

KC5VPF Gets Extra Time on Mir

NASA has delayed next month's space shuttle flight to Mir, leaving American astronaut David Wolf, KC5VPF, aboard the space station for at least another few days. The shuttle Endeavour was supposed to blast off January 15, but NASA announced December 8 that January 20 will be the new launch date.

Wolf, who's been on Mir since late September, learned of the delay last weekend. The delay will give the Russian crew time to do additional work on Mir, including three spacewalks and the arrival of another supply ship. NASA also wants to check out problems discovered on the shuttle Columbia which returned to Earth last week after a two-week mission. Also, one of Endeavour's cargo bay doors accidentally was dented last week.

During the January mission, the Endeavour will pick up Wolf and drop off his replacement, Andy Thomas, KD5CHF. Thomas will be the last US astronaut to live aboard Mir.

Ham Satellite Frequencies OK at WRC '97

Frequency allocations used in amateur radio satellite communications fared well at the now concluded World Radio Conference (WRC 97) held in Geneva, Switzerland.

WRC 97 delegates did agree to upgrade the Earth Exploration Satellite Service from secondary to primary at 1215 to 1300 MHz, which should have only minimal impact on amateur use of 1240-1300 MHz. The presence of these satellites reduces the possibility that other, less-compatible services might later be introduced into this band.

In other allocation decisions, amateur satellite segments were not included among allocations for wind profiler radars. Except for a worldwide primary allocation at 1270 to 1295 MHz, the only specific allocations for wind profiler radars are in Region 1, and those are on a secondary basis.

Region 2 administrations were urged to implement wind profilers in radio location bands at 440 to 450 MHz, 904 to 928 MHz, 1270 to 1295 MHz and 1300 to 1375 MHz, while protecting amateur satellite and weak-signal operations. The delegates also agreed that the frequencies between 420 to 435 MHz or 438 to 440 MHz could be considered for use in situations where there was incompatibility between wind profiler radars and other radio applications. In this case, too, the amateur-satellite segment is protected.

Plymouth Balloon Launch Successful

Hank Riley, N1LTV, balloon launch Technical Director for PCIS-1, a small, high altitude balloon with a tiny expendable 2 meter CW beacon aboard, reports the balloon was launched December 9, 1997 under near perfect sky and wind conditions.

Winds were very light and Hank says the balloon rose gently almost straight up and then off to the north. Optical contact (without even binoculars for aid) was maintained for almost 20 minutes.

The beacon signal was picked up by N1LTV (at 24 statute miles distant) within just minutes of launch using only a 2 meter FM handheld and a four element beam. At 15 minutes into the flight, Hank was able to copy the beacon with a rubber duck antenna attached to the HT.

N1LTV is awaiting QSL reports. Several trackers have signal records covering well over an hour of beacon transmissions. Hank also reminds stations that it's also quite valuable to hear from those stations who attempted to copy the balloon and did not. This will aid in the effort to understand signal conditions during the flight.

An SASE if required if you'd like a Balloon QSL card. N1LTV asks stations to include information about your receiving and antenna equipment, as it will be useful for the post-flight analysis. Hank reports his callbook address should be used for all QSL requests.

T49C News

Mike, N1JEZ, reports that if you were fortunate enough to work T49C via satellite last November, you should check out their Web site at:

http://sk7do.te.hik.se/clubs/sk0ux/T48RCT.html

There is an "electronic" QSL server online. Search for your call. When it comes up, select it and download a .PS file (Postscript). Send this to your printer and you will have a QSL card. The satellite contacts made by T49C were in addition to the over 8,000 HF contacts the DXpedition made from the rare Cuban grid square (FL11) during the CQ WW CW contest.

Mir

(Uplink 437.850 MHz FM, Downlink 145.800 MHz FM)

As part of ongoing frequency experiments to improve amateur radio operations on board Mir, and to better understand how these frequencies will be effective on the International Space Station, Mir will begin a 2-phase frequency experiment beginning December 1, 1997 and ending on May 31, 1997.

For phase 1, a 70cm/2m crosslink experiment will operate for a 3 month period from December 1, 1997 up to March 1, 1998. On December 1, 1997 the Mir operating frequencies will change to:

Uplink: 437.850 MHz Downlink: 145.800 MHz

Phase 2 of this experiment will use a 2 meter-only set of uplink and downlink frequencies. This phase of the experiment will begin on March 1, 1998 and will also be of 3 months duration.

SAFEX, Mir 70cm Repeater

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

The SAFEX activity very intermittent.

Beacon 1 = 435.504 MHz
Beacon 2 = 435.548 MHz
Pwr 435 MHz Beacons = 1.6 W

RS-17

(Beacon 145.820 MHz FM)

Operational.

Sputnik RS-17 is still going strong. Its 100 mW beacon has been head around the world. Sputnik has a tentative life expectancy of 3-6 weeks on batteries. There are no solar panels on Sputnik. Since it was launched on November 3, 1997, it is expected to last until the December time frame. Sputnik is now flying ahead of and below the Mir Space Station.

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 g3cwv@amsat.org.

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 http://www.users.zetnet.co.uk/clivew/.
