FIELD DAY '94 A SUCCESS!
HR AMSAT NEWS SERVICE BULLETIN 184.01 FROM AMSAT HQ
SILVER SPRING, MD JULY 2, 1994
TO ALL RADIO AMATEURS BT
BID: $ANS-184.01
'94 Field Day Operations Considered A Major Successs
Field Day '94, June 25-26th, proved once again that satellite stations and
contacts are considered to be an important part of Field Day (FD) planning.
Although only a few reports have started to trickle in, it is clear by
listening to the downlink passbands that Field Day enthusiasts had more on
their minds than making the one "perfunctory" contact to earn the 100 bonus
points. They were on the "birds" to make points for their stations. The
passbands on every OSCAR were jammed with stations calling "CQ FD." Below
are some of the FD reports that have shown up on INTERNET and at AMSAT-NA
HQ:
N6DD operated his FD station from his 29' long houseboat on the Colorado
River 65 miles south-east of Las Vegas, NV. His yagi antennas were mounted
atop his houseboat and were steered using the "armstrong" method. Although
it was quite hot, about 120 degrees F (50 degrees C), and winds picking up
right at AOS for some of the LEO OSCARs, N6DD was able to make 65 contacts
with most of them coming from AO-10. N6DD says that he wished they had
made more contacts but they were please with their satellite contacts in
general. N6DD operated as class 2C NV. Next year he says that they will
investigate an automatic antenna pointing system. Their station consisted
of station setup KLM crossed yagis on VHF and UHF, a homebrew 2 element 10M
beam on the elevation boom, a FT-736R + twin Mirages, and for 10M a Kenwood
TS-130.
Field Day '94 for W0TWU was an adventure, he reports. Although he didn't
expect to be operating with temperatures of 107 degrees F, it was, however,
a good test to see if both the equipment and operators could survive! From
Central Kansas they worked 298 stations on AO-10 and 301 stations on AO-13!
They tried to work FO-20 but found they had a desense problem. Next year
W0TWU says he plans to try Mode-S on FD.
N2NRD operated clase 1E from his back yard with his antennas mounted on a
tripod to support his KLM-40CX & KLM-22C atenna combination. Although his
"line-of-sight" was blocked at low elevations by his house, this caused
only minor problems during N2NRD's FD effort. N2NRD's station equipment
used: ICOM 271H/471H, KLM 40CX/22C, Kenpro 5400 antenna rotator combina-
tion, ICOM preamp, 70cm TE amp, Astron VS-50M power supply, Kenwood TS-830
and a 29MHz vertical/dipole HF antenna combination. N2NRD made over 250
contacts! One surprise of this FD was AO-10. N2NRD reports that AO-10
"was the best I have heard it in years. At apogee the signals were strong
with very little fading. Perigee had AO-10 pass over-head at high elev-
ations with very strong signals making for a good QSO run." N2NRD's plans
for next year include operating the same sation setup but from a location
that provieds an excellent view of horizon in all directions. Also, he
plans to spend more time operating CW and get on the digital birds!
The FD satellite station at WM5U, the Lockheed Radio Club in Fort Worth, TX
was part of a 2A NTX operation. Satellite availability was better than the
operators of WM5U thought it would be. A new antenna setup provided them
with a lot of technical problems which caused them to miss the first AO-13
window completely. The heat combined with a lack of operators made operat-
ing difficult on Saturday afternoon. But they managed a bit of a come back
over the remainder of the contest period. Results were a bit disappointing
because they were striving to make alest 100 QSOs. They came up a bit
short with a total of 94 QSOs. WM5U made 33 CW contacts and 61 voice con-
tacts using all the available OSCARs. Their station consisted of the
following equipement: Yaesu FT-736R, a Kenwood TS-140S, Landwehr Pre-Amps,
Mirage B-1016G & D-1010 power amplifiers, KLM 22C & 40CX (on a 15' Create
Roof Tower) with a Yaesu G-5400B w/KC Tracker/Tuner, a DSP-12, and finally
a 386SX-16 IBM PC. The operators doubt that they'll rank very well in the
AMSAT competition this year but do note that it was fun anyway!
The above FD '94 reports are just a few of the summaries of from the sta-
tions that operated the OSCARs under FD conditions. But they indicate that
a great deal of effort went into setting up and operating the OSCARs dur-
ing FD '94. AMSAT congratulates all those who worked the birds during
FD '94 and looks forward to seeing more hams on the birds in FD '95.
[The AMSAT News Service (ANS) would like to thank N6DD, W0TWU, and KG5OA
for these FD '94 reports. ]

STS-65 SAREX READY FOR LAUNCH!

SILVER SPRING, MD JULY 2, 1994

BID: $ANS-184.04
STS-65 SAREX Mission Planned Launch of 08-JULY-94 Still On Schedule
The next Space Shuttle mission, with the Shuttle Amateur Radio Experiment
(SAREX) payload on-board, is currently slated for launch this Friday July 8
at 16:43 UTC. Note that this launch time is 23 minutes earlier than what has
been reported previously. The STS-65 Space Shuttle Columbia mision will
carry Amateur Radio operators Don Thomas, KC5FVF and Bob Cabana (license
pending) into a 28.5 degree inclination orbit for a 14 day mission. The
primary objective of this flight is to perform microgravity research
as part of the International Microgravity Laboratory (IML-02) mission.
Thirteen schools from the U.S., Japan, and Germany have scheduled ham radio
contacts with the astronauts. Ten of these school group contacts will be
performed using AMSAT's worldwide network of telebridge stations. The tele-
bridge allows students to talk to the Astronauts through a remote ground
station that is linked to the school though a phone bridge. The Goddard
Amateur Radio Club, WA3NAN expects to retransmit some of these school contacts
as part of their Shuttle Transmission activities. A limited number of schools
who wish to "easedrop" on the STS-65 school group contacts via a listen only
phone connection are encouraged to send e-mail to Frank Bauer, KA3HDO, with
your request. Your request should incluude an explanation of how you are going
to use this listen only dialog in your classroom setting. Mr. Bauer's e-mail
address is ka3hdo@amsat.org.

So far, the ONLY real-time satellite tracker that I've found for UNIX
(in C) is Manfred Bester's SatTrack.
Version 1.7 (the latest) is available for ftp at ftp.jvnc.net in
/priv/kupiec/sattrack. You might want to look at that for help.
Good Luck.
