* STS-59 SAREX NEWS *
=====================
The following are some packet frames received from the Space Shuttle
Endeavour by Andy, WA5ZIB:
W5RRR-1>SAREX [04/12/94 10:13:38] <UI>:
This is STS-59 SAREX Robot station W5RRR-1
onboard the Space Shuttle Endeavour.
W5RRR-1>QST [04/12/94 10:14:01] <I S4 R0>:
Thanks to all of you hams who have connected to our packet station
and worked us on voice! It really makes us feel closely connected
to the people and places that we are flying over. On board Endeavour
things are working very well - the scientists are very happy with the
data they are acquiring. I am very happy to be back in space, and it
all feels very familiar and nice. Our crew has been very well trained,
and we were able to accomplish all our tasks as scheduled so far.
We have had some spectacular views of Earth - we just flew over Tahiti,
for example.

* SOLAR ECLIPSE INFORMATION *
=============================
On 1994 May 10 (Tue), an annular solar eclipse will be visible throughout
North and Central America. The May issue of "Sky & Telescope" (p 72ff)
details this event, the last of its type visible in the continental US
until 2012 May 20.
Scott, KF9QK, plans to monitor 10-meter beacons for the effect of the
eclipse on radio propagation. Of interest is a predicted 'bow shock'
effect on ionospheric propagation as the annular eclipse proceeds, so
amateurs should plan observations well ahead and after their astronomical
eyeball brethren. Observations of any effect on V/UHF propagation are also
of interest. A log of conditions before, during and after the event would
be most helpful. "Sky & Telescope" provides the needed planning
information. Radio observers, of course, need not worry about atmospheric
conditions.
Weather-wise, observers can also expect noticeable shifts in temperature,
pressure and wind during the annular eclipse. An observer in Indiana has
requested such information, which, if forwarded to KF9QK, will be relayed.
Again, the better the log, the more it's worth.
Scott may be reached via packet radio at: KF9QK @ N9HSI.IL.USA.NOAM

* AMSAT PBBS MOVE *
===================
The AMSAT PBBS changed frequency and modes on April 15th at 1600 UTC.
The AMSAT PBBS will be on a Mark frequency of 14.079 MHz, (that's
14.1811 MHz AFSK LSB), using Pactor with the callsign WT0N. The new
schedule will be as follows: Monday through Saturday from 1600 UTC until
2300 UTC on a Mark freqeuncy of 14.079 MHz. From 2330 UTC until 0400 UTC
on a Mark freqeuncy of 7.0735 MHz (that's 7.0756 MHz AFSK LSB), using
Pactor. These changes have been made to better serve AMSAT users with
greater coverage and use of a mode that many of the users have expressed
an interest in. If anyone would like to use the Mode G-TOR, please let
WT0N know and he will see about setting up a schedule for G-TOR users.
Please send any comments or suggestions to one of the following:
INTERNET: BJARTS@STTHOMAS.EDU
PACKET: WT0N@WB0GDB.#STP.MN.USA.NOAM

* JOHNSON SPACE CENTER BBS INFORMATION *
========================================
The Johnson Space Center Amateur Radio Club has set up a telephone computer
bulletin board (BBS). The purpose of the BBS is to provide a source of
current Space Shuttle mission Keplerian Elements.
There are limited number of BBS files available for downloading.
Among the current files are:
o Current and old element sets for the mission in progress
o Current mission information
o Shuttle Amateur Radio Experiment (SAREX) information
o Recent Space Shuttle Mission Schedules and Manifests
o Astronaut/Cosmonaut Ham List
o Current JSC Amateur Radio Club Newsletter
We ask that no files be uploaded to the BBS.
The telephone number is (713) 244-5625. The speed is anything
up to 9600 baud. The parameters are N-8-1.
The BBS is currently running in ProComm HOST mode, so the log on is very
simple and downloading is easy.
After logging in you will see the Welcome Screen describing the BBS.
Also, the Welcome Screen contains the current and latest element set
number (e.g., JSC008) loaded on the BBS. Check it against your last set
so you won't waste your time duplicating a set you already have.
Press ENTER to bring up the second page containing the current Space
Shuttle Keplerian Element Set. If you have a file capture or screen
capture function in your communications software, use it for this page.
That way, you won't have to go through the file download process if all
you wanted was the latest element set.
If you have any comments for the Club or BBS sysop, leave a message and
the sysops will respond.

* AMATEUR SPACE SHOT *
======================
With funding from the National Space Society, the Pacific Rocket Society
(PRS) is building a nitric acid/furfuryl alcohol rocket designed to
achieve an altitude of 80 kilometers--the edge of space.
Of interest to the AMSAT folks is the television and data telemetry
payload designed and built by Duncan Cumming, KD6GKE. (Duncan is a
native of Birmingham England and holds a PhD in Electrical Engineering
from Cambridge University.) The system transmits video from a small
security camera at 434 MHz and data at 145.75 MHz.
The data channels include GPS, magnetometer, accelerometer, altimeter,
launch detector, engine temperatures and pressures and status switches.
The heart of the system is a Tattletale IV single board 6303 based
computer.
An article on Duncan's telemetry system, co-authored by George Morgan,
WB6ZUV, appears in the April 1994 issue of "High Power Rocketry."
The launch will be from the Pacific Rocket Society test site in the
Mojave Desert later this year.
The PRS meets monthly in the physics classroom of Chaminade College
Preparatory, West Hills, California. Inquiries about the project can
be sent to PRS president Charles Pooley, KD6HKU at ckp@netcom.com or
to Dave Reeves at kf6pj@amsat.org or chaminade@amsat.org.

Repeater Frequencies Needed:
I have recently purchased one of those Radio Shack specials, the 2
meter one.
I will be going on a trip this summer from Moscow Idaho to Albuquerque NM
and would like frequencies that I can listen to along the way (since I don't
have a license yet!). I am planning to purchase the $6.00 frequency guide
from ARRL in the near future, but what I need are frequencies for the nearby
area of the following towns in the 2 meter range (144 to 148).
Towns:
Boise, Twin Falls, Salt Lake City, Cortez Colorado, Albuquerque NM.
If there are other towns on the map in between those areas that have repeater
frequencies, please include those also!
Thanks!

Subject: April - Amateur Radio Month ??
To: info-hams@ucsd.edu
I heard last week on the local broadcasting station that this month is
Amateur Radio Month.
When I enquired about this at our local club meeting, no one has ever
heard of this before. So a quick call to the local broadcaster confirmed
that according to a service which track this sort of thing it is indeed
Amateur Radio Month. And that this is promoted by ARRL.
Does anyone else know about this.
If we had known earlier we would have put on an event to help promote this!!

For some reason, my outgoing email isn't working...
I'm no chemist, but I think baking soda (maybe mixed with a little water)
should do the trick. I know it works with car batteries (lead acid), but I've
never tried it with alkalines.

What you use to neutralize the cell leakage is relative to the cell used in the
radio.
In your case where Energizer cells were used, neutralize with kitchen ammonia.
Use a cotton swab and bathe the affected area. If necessary to remove crusted
material, gently scratch with an Exacto knife blade. Continue to bathe the
affected area with solution until there is no evidence of foaming/reaction.
Then, the most important step is to wash out the ammonia and acid with water.
Again, use a swab and flush the area many times and dry completely to remove
all traces of water.
Because the cell leakage and cleaning process removes all surface protection,
restore moisture as best possible. Clear fingernail polish should be used on
all non-contact surfaces. A light film of oil may be placed on contact
surfaces.
If the leakage had been from an alkaline cell, such as a nicad, use vinegar and
follow the same process as indicated above.

I've been looking for the AC power supply to run

one, but it appears to be an HP23. I believe there were
also a and maybe b and c models of the power supply. I'm
assuming that these were revisions of the original.
Can anyone say anything about the differences
between the earlier/later versions?

I must second sandy's comments about HostMaster for the mac; I'd been using
terminal programs for several years (whitekinight, miicrophone, etc), and
it was during a rtty qso with another kam+ user that I came to appreciate
what HostMaster could do; Since I bought it I've never gone back to a term
emulator, and wonder why it took me so long...
Whist on the bandwagon, I'll also second the mention of MARATHON, which
i've used in only one contest but *loved*;

QST:
"Nose" was my first Hawaii contact. His voice was weak but he hung in
there.
I told him that I had wanted a QSO with him for quite a while since his
call was the same as my dad's.
My dad got his license in 1917. His call was 9IJ. (no other prefix in
those days.)
When Nose sent me his QSL card, he included a very nice note with it
commending me and my dad. What a nice guy. I remember all those great
articles in QST.
I worked him one other time about a year ago from the club station here,
W9NAA. His QSL is displayed prominently on the shack wall.

having never tried it, I would opt for 2 mtrs or 70 cm. Seems the VHF/ low

Of course the range might be some what dismal, it is after all

I tried for a month to work Oscar 21 with my FT767GX and 10 watts. Even with
a quagi or medium size helix and no one else on the bird at all it just
doesn't have enough kick to get through. I picked up a 70cm amp kit
from Communications Concepts. Less than $200, you just add connectors and
a heat sink and away you go. It is rated for 18W in 100W out at 28VDC but
I drive it with the 10 watts from the 767 and use the 767's internal 24VDC
power and get about 60 watts output. Even into a ground plane or discone
antenna that works OK for AO-21. You just have to wait until the BIG GUNS
take a breath and slip your call in. If you add a high gain antenna
(I'm using a 10 turn helix) you can work AO-21 anytime its above the
horizon.
If you're in a hurry to make some FM satellite contacts, try AO-27
(145.85up/436.800down +/- 13kHz doppler). Ten watts to a ground plane
is plenty for this one, although it is only scheduled on weekends and
then only when the solar panels are illuminated by the sun.
*NOTE TO ALL AO-27 USERS*
If you don't hear your own downlink right away, tune between 436.875 and
436.915 and *LISTEN* for activity. Also, you might require a filter on
your receiver to cancel to 3rd harmonic from the 2m uplink.
Many an AO-27 pass is unusable because of strong stations that cannot
hear the satellite crooning "Heeelllooo" for the duration of the pass.
