TO ALL RADIO AMATEURS BT
AMSAT-NA To Operate a "All-Satellite, All-Mode" OSCAR Station
In celebration of the 75th anniversary of the founding of the American
Radio Relay League, there will be a commemorative station operation
under the callsign of W1AW/5 on 2-4 June, 1989. This activity will
take place at the ARRL National Convention in Arlington, Texas. The
hours of operation will be from 17:00 UTC on Friday, 2 June, through
18:00 UTC on Sunday, 4 June. In keeping with the convention theme "FROM
SPARK...1914-1989...TO SPACE," a "deluxe" satellite station will be set
up. It is the intention of station planners to operate this station on
every pass of every Amateur Radio Satellite that comes within view of
Arlington, Texas, during the operating period. In the case of the
UOSATS, demonstrations of bulletin and telemetry capture are planned.
All modes of operations will be supported from Mode A, B, J, and L.
Both AO-13 and AO-10 should be usable that weekend along with RS-10/11,
FO-12, UO-9, and UO-11. Crank up your tracking programs and check your
windows "of mutual visability" to Arlington, Texas, (between Fort
Worth, and Dallas) for 2-4 June,1989.
Icom, Tandy, Telex-Hy Gain, KC Tracker, and other manufacturers are
providing support for this event. The ARRL is providing special QSLs
for this event featuring the "Spark...To Space" logo. Every amateur
satellite station in the country should have one of these exceptional
QSLs.
AMSAT-NA will be well represented in other ways at this convention.
Forums on Microsats and Phase IV will be presented on Saturday by Doug
Loughmiller, KO5I, President of AMSAT NA and Dick Janssen, WD4FAB,
respectively. On Sunday, Keith Berglund, WB5ZDP, will present an
introductory level satellite forum.
If you are coming to the convention, please come by the AMSAT Booth or
the Commemorative station to volunteer your operating assistance for
the Commemorative Station. If you would like to volunteer in advance,
please contact Keith Pugh, W5IU, at (817) 292-5633.
Last but not least. A full size model of the AMSAT-NA PHASE IV project
will be on display in the convention lobby for all interested parties
to see. It will be hard to miss since it is approximently 8 ft. in
diameter and was constructed by students from the Center of Aerospace
Technology (CAST) from Weber State College in Ogden, UT. "See you on
any of the birds during the weekend of 2-4 June, 1989."

SHASTA SPACECON '89
HR AMSAT NEWS SERVICE BULLETIN 133.02 FROM AMSAT HQ
SILVER SPRING, MD MAY 13, 1989
TO ALL RADIO AMATEURS BT
All Amateurs Are Invited for a "Beginners" Seminar On OSCAR Basics
Bob Dalleske (W6AMW), AMSAT-NA Area Coordinator, is pleased to announce
that an all day seminar about OSCAR satellites is being planned for the
northern California area known as "Shasta SpaceCon '89." This seminar
will take place at the Student Center at the College of the Siskiyous
located in Weed, CA. According to Bob, this seminar is being designed
for amateurs, who at the present time, have only a "casual interest" in
OSCAR satellite communications and would like to learn more about this
exciting aspect of amateur radio. Bob has lined-up an impressive group
of speakers which include: Ross Forbes (WB6GFJ), President of Project
OSCAR, Courtney Duncan (N5BF), AMSAT-NA VP of Operations, Cliff
Buttschardt (W6HDO), Frank Dziurda (K7SFN), Bob Lahde (NA6E), Steve
Roberts (N4RVE), and Ed Westbrook (WA6IUM). These experienced
satellite users will be "gearing" their forums to folks who want to
know what it takes to to get on the AO-13. They will cover such topics
as "What are Amateur Satellites and what does the future hold,"
"MICROSATs: The new 'bird' on the block," "A beginners guide to AO-13,"
and many, many more topics ranging from equipment needed to get
started, and problems which beginners usually encounter getting
started. Bob stresses that "technical-jargon" will be kept to a
minimum because this conference is designed to inform all those who are
not necessarily versed in the technical aspects of satellite communic-
ations -- in short, you don't have to be a aerospace engineer or RF
communications "type" to find this seminar useful. For more
information about this excellent beginners conference, contact Bob
Dalleske, W6AMW, at (916) 964-3154 or send a s.a.s.e to

RUSSIAN PHRASES FOR AMATEUR RADIO:
This is a new 20-page syllabus compiled by W6HJK to help amateurs
better communicate with their Soviet colleagues. You need not be an
expert in Russian, only interested in "trying."
The booklet provides (1) English words and phrases for QSOs,
accompanied by (2) the Russian translation and (3) the English
transliteration, to assist you in pronouncing the Russian.
The syllabus follows the natural sequence of a QSO. There are
additional sections on the Russian alphabet, phonetics, CW characters,
numerals, and given names. Suggestions are made for addressing mail
to the Soviet Union.
The author undertook this project out of a personal interest in
improving the quality of his QSOs with Soviet hams and
to enhance USA-USSR relations. This booklet is provided free of
charge, with the first printing and mailing funded by Beyond War, an
educational foundation to build global dialogue and cooperation. If
it is useful, you may later choose to make a contribution to help
sustain this project.
Requests should be sent to:

PAKISTANI BIRDS:
I believe that I might be able to shed some light on the
recent IFRB filing by Pakistan wrt their BADR-1 spacecraft.
(BADR = new moon, in Urdu)
We have been aware that SUPARCO (Space & Upper Atmosphere
Commission of Pakistan) has been building a small satellite -
based on the UoSAT experience and intended for launch on the
Shuttle (the structure is closely based on the NUSAT scheme).
UoSAT has co-operated with SUPARCO for several years, with a
number of their scientists and engineers taking Masters
degrees at Surrey and undertaking projects within the UoSAT
Unit. The original intention was for SUPARCO to work
alongside UoSAT to develop a small spacecraft, however after
working closely with UoSAT for a year or so they decided that
they were in a position to 'go it alone'!
SUPARCO in Karachi and at the University of the Punjab in
Lahore have two groundstations which have been participating
in the UO-11 DCE, operating with amateur radio calls of AP2SUP
and AP2PUL.
UoSAT has not been involved in any way (at least, knowingly)
in the design of the BADR spacecraft and certainly not in the
selection of frequencies. I had, however, surmised the
frequencies some time ago after I was informed of a crystal
order that they had placed with a manufacturer!
To the best of my knowledge, SUPARCO intends to operate these
spacecraft within the amateur satellite service. The choice
of frequency does not appear to relate to any band-plan of
which I am aware.
I hope the above sheds a little light.

FREE FALL MIPS:
The software operating system which will be used on both the AMSAT-NA
microsats A-D and on the University of Surrey's UoSAT-D PCE is now
running on all of the target hardware.
The PCE prototype arrived at the offices of Quadron Service Corporation
in Torrance, California this week, and is now running the software.
Quadron is dontating the use of its commerical operating multi-tasking
system, qCF to the amateur radio satellites. The software has been
running for several weeks on the wirewrap version of the Microsat CPU.
More information on this weeks's PCE events should appear shortly from
AMSAT-UK.
To give you an idea of the amount of orbital compute power that will
be available after the launch of these satellites, I've run a
compute-power benchmark on several machines, the results are given
below. To give you an idea of the software development
capabilities, the same C source code and the same compiler was used
on all the below hardware. The ability to run on any of these machines
makes developement and debugging easier than before, gives us the ability
to use a commercial compiler (Microsoft C), and allows for easy exchange of
ideas and software between Surrey and AMSAT-NA. The qCF operating
system allows many indendant C programs to run simulateously, and
provides a program to program message exchange facility. Programs
are compiled and linked with standard Microsoft utilities; the
resulting .EXE file is fed to an upload program for transmission to
the spacecraft, where it is added to the mix of running tasks.

** UoSAT PCE data added **
Using a dhryston C benchmark from Sept. '86 DDJ p.88, here are some
performance numbers (using a 6MHz AT as the index). The
same compiler and options were used (/AS /Ze /Zp /Ot /Gs ). /Gs (no
stack checking) was used because the S/C stack check is different than the
dos version. Normally /G1 (80186 instruction set) would be used for
S/C programs.
The RIC is the PC card we're using for the simulator and for SW development.
Device CPU Clock dhrystons/sec index
IBM PC 8088 4.77 MHz 531 0.29
AMSAT flight V40 4.608 MHz 538* 0.29*
AMSAT proto V40 7.372 MHz 861 0.47
RIC 80186 7.3728 MHz 1391 + 0.75
UoSAT PCE 80C186 7.3728 MHz 1398 + 0.75
IBM AT 80286 6 MHz 1850 1.00
AT Clone 80286 8 MHz 2145 1.16
Toshiba 3200 80286 12 MHz 3762 2.03
+ The timer resolution of 10ms gives an uncertainty of +-14 counts,
these numbers are equivelent.
* calculated estimate based on clock speed difference from the
wirewrap prototype.
The RIC, Microsat Prototype, and UoSAT tests were done under the
multitasking kernal, so clock and scheduler overhead are included.
Zero wait states were used.
The difference between the PCE and Microsat proto in the above numbers
is 16 bit vs 8 bit buss. Differences in the number and use of DMA
channels, mass memory access schemes, and the fact that most of the
processing will be on 8-bit bytes makes it hard to estimate actual
performance.

DINNER WITH U2MIR:
On Friday night, May 12th several of us in the Washington DC area had the
privilege of meeting Musa Manaroff (phonetically, the correct
pronunciation is something like mun-ARE-off ), U2MIR for dinner at
W4PUJ's QTH. We took advantage of Musa's trip to the USA where he is
meeting with a number of space medicine scientists as the "specimen" to
show that a human can survive 366 days in orbit with no ill effects. His
trip will also take him to Houston and New York.
Although we had some language problems, Musa's English was far better than
any of our Russian and as the evening wore on, we all became more relaxed
and communications continued to improve. Musa told many anecdotes about
his trip. He commented that one year away from his family (he has two
children, a girl 8 and a boy 7). When asked how long he was in orbit, he
said 366 days, and 366 times 16 nights! He told about the size of MIR
(about two normal rooms). He told that they ate well and passed their time
playing video games and reading. He commented that such a long mission is
very boring and that when the amateur radio equipment (a Yaesu FT290
transceiver) arrived in early November it provided much enjoyment. We all
found Musa to be a most personable young (I'd guess his age at about 33)
fellow!
Musa received the U2MIR license while in orbit. Although he is an
electronics engineer he had only been an SWL before, but he plans to stay
active and he hopes the bureaucracy will let him keep using the U2MIR
call. He enjoyed tuning around the AO-13 passband and 20 meters on W4PUJ's
receiver. He said he is looking forward to learning to operate on CW.
We told him of the AMSAT programs including our plans for Ron Parise to
carry hardware aboard the shuttle next year. We showed him what the packet
radio hardware Ron will use (a Tasco/Heath HK21 TNC) will be like. We told
him of our Microsat activities and were able to show him a couple of the
receivers that are being built here. We then presented him with an
honorary AMSAT life membership; he was interested to know that Arthur
Clarke had also received one. We also presented him with several AMSAT
pins and the new Microsat embroidered patch.
Those of us from the DC area that were present were Dick & Jackie Daniels
(W4PUJ), Rich & Phyllis Zwirko (K1HTV), John & Martha Shew/Saragovitz
(N4QQ) and Tom & Elizabeth Clark (W3IWI).
