MIREX APRS TEST RESULTS

HR AMSAT NEWS SERVICE BULLETIN 074.01 FROM AMSAT HQ
SILVER SPRING, MD, MARCH 15, 1998
TO ALL RADIO AMATEURS
BID: $ANS-074.01

As announced by ANS, the MIR International Amateur Radio Experiment team 
(MIREX) held an Automatic Packet/Positioning Reporting System (APRS) test
on March 10, 1998. APRS stations were encouraged to use the Digital
Repeater (R0MIR) aboard the Russian space station.

On the day of the test, Bob Bruninga, WB4APR, first reported that because 
R0MIR was unexpectedly off the air during the two designated APRS/MIR test 
orbits, the MIREX team authorized an extended test during the next two 
orbits over north America. Both of these passes, however, took place when 
most operators would be asleep.

Even with unconventional hours, when the APRS packets finally began being 
digipeated via MIR, the special APRS/MIR Internet page began plotting 
stations instantly. Being able to see this event live worldwide via the 
Internet without a radio was one of the main attractions of the experiment, 
both for amateurs without APRS equipment, and for many schools lacking VHF 
receivers.

During the day of the APRS/MIR test, the live APRS web site scored a 
maximum of over 11,000 hits, with the peak load reported at 155 
simultaneous users.  Most of the APRS stations shown on the web site during 
the actual test were home stations (due to the hour of the rescheduled 
test), however, 5 mobiles and 1 Naval Academy boat were seen.

Steve, K4HG was in a perfect position to be one of the first to see 
stations appear on the APRS web site. "While many were sleeping, dozens of 
packets were digipeated by MIR. I was one of the first stations digipeated 
through MIR, not surprising given my location and where the space station 
was. It looked especially cool on the APRS page... it was blank, then 
suddenly all these stations started popping up!"

Mike, KI7AB, reported seeing California and Washington stations, one of
which was mobile in Seattle area. Joe, KC6SZY, reported seeing many APRS
stations on his computer screen, adding, "it looks like things worked."

MIREX reported this experiment had been in the planning stage for some time 
and the team hopes it will serve as a step for other experiments.

AMSAT-UK MODE A SURVEY RESULTS

HR AMSAT NEWS SERVICE BULLETIN 074.03 FROM AMSAT HQ
SILVER SPRING, MD, MARCH 15, 1998
TO ALL RADIO AMATEURS
BID: $ANS-074.03

Richard Limebear, G3RWL, AMSAT-UK Communications Officer, recently surveyed 
satellite operators worldwide about the possibility of another mode A 
satellite. Richard posted the results of the 'do we want another Mode-A 
bird' survey on the AMSAT-NA Bulletin Board.

G3RWL noted that because of the very short time scale for responses, he
limited distribution to electronic means only. Of the 200 responses 
received,
Richard reported the vast majority would be in favor of a new mode A bird. 
Some
additional comments received included FM rather than SSB or CW modes,
a higher orbit, mode K and/or mode T transponders, possible HF beacons,
and the need for analog transponders. Richard reports he will be doing a
complete report in an upcoming issue of the AMSAT-UK Oscar News.

CHICAGO AREA SATELLITE LECTURE

HR AMSAT NEWS SERVICE BULLETIN 074.04 FROM AMSAT HQ
SILVER SPRING, MD, MARCH 15, 1998
TO ALL RADIO AMATEURS
BID: $ANS-074.04

Satellite and other interested amateur radio operators in the Chicago area 
are invited to a lecture on satellites, with the main focus on 
contributions of the Radio Amateur Satellite Program.  The speaker will be 
Dr. Martin Davidoff, K2UBC. He will address the development of low cost 
space technology at the Argonne National Laboratories, on Monday, March 30, 
1998. The lecture, beginning at 2pm, is free and open to the public

The lecture will take place in the auditorium of the Physics Building at 
the  National Laboratories, also known as Building 203. A map of the area 
is available at the following URL:

http://www.anl.gov

Bill Parmley, KR8L, AMSAT Area Coordinator for Idaho, has arranged for the 
presentation to be videotaped and shown at the Argonne-West facility, which 
is located near Idaho Falls, Idaho.

Dr. Martin Davidoff, K2UBC, is best known in the amateur satellite world as 
the
author of the highly acclaimed Satellite Experimenter's Handbook and the 
new
Satellite Handbook. Both volumes are published by the ARRL and are 
available
from the League, or from AMSAT-NA Headquarters.

Operational. The new modem is a Kantronics KPC-9612 Plus, Revision 8.1.
Please note the command set for this TNC is different than the previous MIR 
TNC.  MIREX suggests a copy of the KPC-9612 manual may help in
understanding the changes. Dave Larsen, N6CO, tells ANS the Personal
Message System (PMS) on MIR supports a 'system operators' mode with the
special call sign, K6MIR, reserved for PMS SysOps. Only the system
operators are allowed to use this callsign. N6CO asks stations not to 
attempt
to connect to this call.

Joe, W2KQ, reports a voice contact with Andy Thomas aboard MIR using the
145.985 MHz downlink frequency. W2KQ used an FT-736R at 20 watts and a
vertical, reporting S-9 signals. Mike, VK8ZMA, also reports working MIR, 
with
Andy using his VK5MIR callsign, noting solid Q5/S-9 voice copy, horizon to
horizon.

MIREX has created an Internet Web page containing information regarding
MIR and the various ham radio experiments taking place from the space 
station. Please check out the pages for pending and proposed projects.
