Sorry about the deluge of digests; I just fixed the gateway and we had 10
days worth of traffic to catch up on.  Things should tame out now.

As many of you know, these mailing lists are gatewayed bidirectionally with
newsgroups on Usenet.  Recently those newsgroups underwent a reorganization,
with the ham-radio group being split into several groups, primarily splitting
off a "policy" group for the discussion of things like no-code, license
classes, rules and regulations, etc.

That newsgroup is now available as a separate digest from ucsd, the ham-policy
digest.  You may subscribe, as always, by sending mail to [e-mail].

Now that everything is working, I'm going on vacation for a week.  Flames will
be extinguished when I get back.

Yes, the contest is the last weekend of March, and QST is wrong.  They
sometimes do get it wrong - both the phone and cw RSGB contest dates were
off by a week last year, or perhaps the one before.  I don't think the
contest organisers worry about Easter, but they try to avoid big football
weekends...

It's the WPX contest, not WW.   And it's only on phone, anyway :-)
It might be fun to listen at 0000 the previous weekend and harrass
any CQ machines that start up then...

TO ALL RADIO AMATEURS

Thanks to Joe Sand, K2GX, and the TRISTATE DX PacketCluster Network
and to Paul, KB1BE, with the Connecticut DX Association, for the
following DX news.

FROM THE DXCC DESK.   Another reminder that the dealine for the DXCC
Honor Roll submissions is March 28, 1991.  Cards must be received by
THURSDAY, March 28 to qualify for the next Honor Roll Listing.  Both
ARRL HQ and W1AW will be closed on FRIDAY, March 29.

BANGLADESH, S2.  A recent FAX, received March 21, stated that Jim
Smith, VK9NS, is leaving Norfolk Island tomorrow afternoon, on route
for Dhaka via Bangkok.  He will be arriving on March 22, after 1 PM.
Jim will be meeting with the Ministry of Information on Saturday
morning.  He has mixed feelings, at the present time, but will keep
in touch with Kirtsi by FAX and telephone.  Listen on the 222 Net
for further information.

CHRISTMAS ISLAND, VK9X.  On April 2 to 9 an operation is planned
by a Japanese group.

ETHIOPIA, ET.  W4IBB, Jack, will return to the USA on March 30,
1991.  ET2A has been consistently found on 21300 KHz at 1900 UTC.
Other activity on 28400 KHz at 1230 UTC and 28636 at 1800 UTC was
also reported.  QSL via WB2WOW.

LAOS, XW8.  XW8KPL is QRV Saturdays.  Try SSB on 15 meters between
1500 to 1700 UTC.

MYANMAR, XZ.  JA8IXN is being deluged with QSL requests for XZ9A.
Masa has stated that he denies all knowledge of this operation.

NEPAL, 9N.  9N1MM meets KA9RLJ most evenings at 0100 UTC on 14253
KHz.  He would be glad to QSO with you.  Father Moran QSLs via
N7EB.

SAN FELIX, CE0.  XQ0X continues to be active on 10 and 15 meters
operating SSB.  Try 21245 KHz or 28495 KHz.  Juan will QRT in
April.  QSL via CE3ESS.

TOGO, 5V.  5V7RF, Dick says he is often on 21335 KHz or 14296 KHz
at 2100 UTC.  QSL via NC6A.

YEMEN, 70.  Gabbie, DL2BCH, tells us that she has the logs for
7O1AA.  She asks us to remind you that German airmail postage is
almost two dollars.  Cards for the operation of 7O8AA are currently
being received here.  Both 9K2CS and F6EXV plan to be in Dayton
the end of April, 1991.

Joe, K2GX, reminds eveyone not to miss the fun next weekend, March
30 and 31, in the CQ WW WPX contest.  There are contest expeditions
planned that are too numerous to list.  However, contesting affords
the DXer an opportunity to fill band and mode requirments and to
hone operating skills in the company of the worlds best operators.

Good Luck on DX de KB8NW/OBS

Subject: First No-code Tech?
To: [e-mail]

A month or so ago I helped administer the novice written to a lady
(a ham's wife) who went on to take the No-code Tech. written option
a few days later.  I do not know if she is the first but she was
certainly one of the first.

Having known this person for several years, I am sure she knew
all that was necessary to pass the test and I know she will operate
appropriately.  It is not her knowledge, skill, or ability to copy
code that concerns me.  It is instead her motives.

I love radio and feel that radio posesses a magic quality that
can not be described.  I became a ham because I enjoy pursuing
radio as a hobby.  If ham radio did not exist I would find other
ways of involving myself in radio.

This lady, and I fear, many others entering our number do not share
this feeling.  She was getting licensed so that she could talk
to her husband -- not because she loves radio.  There are other
business, GMRS, etc. services better suited for persons who are
looking for a personal communications system.

If amateur radio is to survive it must attract people who join
because they are genuinely interested in radio.  Not looking for
a portable telephone or wanting to be able to keep tabs on their
spouse.  As an important mode of communication, code has been
outmoded.  However, in our efforts to move forward and keep up
with technology, we must be careful to attract people motivated
to join our number for the right reasons.

I welcome the new no-code technicians.  May they further the
radio art as much as their predecessors.

[Please excuse my spelling and organization.  This was typed
on the fly!]

Perhaps you should look as this as a way to keep her husband in ham radio,
rather than as an affront to the purposes of HR.

Netters,

   Well I received several responses to my request for information
on the care and feeding of Gell Cells.  The overall response was
that I can treat them as if they are standard Lead-acid batteries.
This is true except that I must limit the charge to less than 20%
of the Amp/hr rating and that they may be trickle charged to
120% of capacity 'for ever'.
  Thanks to those who responded. To save net bandwidth and I will
forward a file that contains all responses upon request.

Believe it or not, many people who fail the 7-out-of-10 questions
pass the 1-minute-solid-copy.  The question-type exam is a convenience
for the examiners (easier to grade) and does not make the test
significantly easier to pass.

SAREX Introduction

STS-37 Crew:
  N5RAW, Steve Nagel, Mission Commander
 KB5AWP, Ken Cameron, Pilot
  N5QWL, Jay Apt, Mission Specialist
  N5RAX, Linda Godwin, Mission Specialist
  N5SCW, Jerry Ross, Mission Specialist

SAREX equipment on this flight includes a 2m (144-146 Mhz) Motorola radio
(output 2.3 watts), Robot 1200C slow scan convertor, Heath HK-21 packet TNC,
a 70cm FSTV receiver, a video camera, and a Monitor/VCR.  Planned operations
include voice contacts, packet robot, downlinking orbiter video via SSTV,
uplinking FSTV video to the orbiter.

During sleep periods and when no other SAREX activities are scheduled the
equipment will be left on in packet robot mode.  If time permits the crew
will setup SAREX to transmit SSTV using orbiter video cameras during the GRO
satellite release and during the EVA.  The GRO satellite release is
scheduled for MET 2/03:00 (2 days 3 hours after launch) for 1 hour.  The EVA
is scheduled for MET 2/22:00 thru MET 3/05:00.  With 5 hams on the flight
there may be many unscheduled opportunities for operation, I suggest you
monitor both downlink frequencies on all passes starting with orbit 1 until
landing, even during sleep periods you could hear something other than
packet.  Contacts between the shuttle and school children will be
retransmitted by W5RRR, see timeline for times, and W5RRR frequency
information below.

SAREX Uplink/Downlink Frequencies

Downlink/Uplink Frequencies for Voice/Packet/SSTV to be used on Upcoming
Mission

Get out your HTUs and HT programming manuals.  You will want to program your
2 meter FM transceivers with the following information.  Note that only
stations with prior arrangements can uplink FSTV signals (special
authorization is required from the FCC).  It is expected that uplinking FSTV
will require about 15kw ERP.  FSTV ops and 2m can occur simultaneously.

Mode           Downlink Freq Uplink Freq
-------------- ------------- -----------
Voice/SSTV     145.55        144.95 (primary), 144.91, 144.97
Packet         145.51        144.91 (primary), 144.93, 144.99
FSTV           none          70cm band

Please note that the frequencies they will be listening for stations ARE
DIFFERENT than the one they will transmit on.  This is a very important fact
to understand.  They will transmit to earth (downlink) on a single frequency
145.55 MHz for voice and SSTV.  They will listen for stations transmitting
to the shuttle (uplink) on the other frequencies listed.  This "split"
operation is used quite successfully by DXers when operating in an
environment where large pile ups are expected.

There will be no simplex operation with SAREX on either voice or packet.
Although packeteers are not accustomed to operation with a TX/RX offset, in
this case, it is the only way to connect to SAREX.  If you transmit on
145.55 or 145.51 MHz the only people who will hear you are those other Hams
in your area trying to hear the shuttle.

============================================================

SAREX Packet Operating Hints

FULLDUP OFF
DWAIT   0.1 - 0.5 seconds
FRACK   > 3.0 seconds
C KB5AWP

The packet call sign on board the shuttle is KB5AWP (SSID=0).  Your TNC
should be in half-duplex mode (FULLDUP OFF) with CD active just like you do
for normal VHF packet operations.  If you can compensate for doppler shift
it is worth the extra effort.  The bandwidth of the SAREX radio is +/-4Khz,
maximum doppler is around 3.3Khz.  If you canUt compensate for doppler your
best chance for contact is when the shuttle is at peak elevation at your
site.

You should be careful with the setting of two of your TNC's timers: DWAIT
and FRACK.  DWAIT is the time interval after your Carrier Detect light goes
out and before your transmitter turns on.  You want to make sure your
connects requests and ACKs are contained in the 3 second FUDtimer window.
If everybody runs the same DWAIT (like the typical 0.1 - 0.5 second values
used for terrestrial packet), then everybody will be transmitting at the
same time.  Part of the key to your success when uplink QRM is heavy is to
pick a DWAIT that nobody else is using!  (sort of like picking a lottery
number!)

FRACK sets the time interval between your transmissions.  After you send a
frame, your TNC waits for the FRACK time, and then waits for the Carrier
Detect signal to drop, then waits DWAIT, and then tries again.  You should
make sure your FRACK is at least 3 seconds so that you are not transmitting
when the robot's FUDtimer decides it is time for it to transmit -- if you
are transmitting at the same time, you will miss any packets the shuttle is
addressing to you and you won't have a successful QSO.

Note that your DWAIT (how soon do I transmit?) and FRACK (then how long do I
wait?) parameters and the need to stop transmitting so you can hear a reply
are just like you encounter when working a DXpedition pileup on HF.  If the
DX station has a pattern of listening for a few seconds (=FUDtimer) before
transmitting, you may have better luck being the LAST station they hear,
after the din dies down.  The differences are that (1) the robot is a
computer and is very predictable and (2) the robot can be working several
stations at one time.

============================================================

Subject: What is a "Sideswiper" CW Key?
To: [e-mail]

   During lunch today I made a CW contact on 20 M with a ham holding a
very old 1x2 callsign.  He asked me how his "sideswiper" sounded because
he had not used it lately.

   I responded by telling him that his bug sounded better than some CW
keyers (I like to humor the Old Timers).

   That was a big mistake.  He spent the next 10 minutes attempting to
explain to me exactly what a sideswiper was and how it was not a bug.
He said that it was 70 years old and was originally installed on
a 2KW spark transmitter on a ship that sailed the Atlantic Ocean.

   The explination was not terribly clear.  So my question to the net is
"What exactly is a sideswiper?"

I knew it would change as soon as I posted that article :-)  As of
today (3/22/91) mission planners are using April 6, 1417 UTC as the
target launch time.  If things go well it could move up to the 5th.
Final date won't be set until the Flight Readiness Review next week,
and as usual, until the SRBs are lit we won't know the real launch time.

There has been a slight change in the planned trajectory, yielding a
slightly different orbit, so here is a new set of Keplerians:
