Hello, everybody. I will be operating the CQ WPX CW contest from
Kingston, Jamacia the last weekend in May. I'll be on the island MAy
25-May 30, and am trying to get a special call for the contest period
(I've asked for 6Y0DX). This will be a single op effort, all-band. I'll
also be on the air off and on before the contest, with both cw and ssb.
I'm also going to try some RS-12 activity.
Any questions, feel free to drop me a line.
73, see ya in the pileups-

True, but the poster wanted to communicate according to their
schedule, not the schedule of some satellite(s). A couple
of geostationary satellites would do nicely toward filling
this need, but I don't see the $$$ being available for it
anytime soon. In fact, I think AMSAT would like to see
more contributions for the Phase 3D satellite...
Amateur radio is generally a poor way of saving money spent on
telephone bills. Yes, there have been people that have done it,
but for each case it which it works, there are numerous examples
where it won't.

In response to the recent request for leads to PC programs helpful to EME
operators, may I suggest "SKYMOON" by W5HN. While I don't operate EME, I've
seen Dave use it a few times and it looks very nice. The fact that W5HN has
the first DXCC on 144 MHz shows it con't be TOO bad.

HELP!
I have a Standard GX3000U(AA) that I would love to use on the
Amateur band. Unfortunately, the Standard EPROM burner and software
don't currently like this freq range.
Any Ideas?
Has this been done before?
If so HOW?
Help or ideas would be greatly appreciated.

If you look at this a little differently, it's easy to see that the number
of poles & zeros shouldn't be significantly affected. Come up with a
pair of filters for quadrature phase that you are happy with for
amplitude and phase matching. Add the same zeros and/or poles to
both. Then the amplitude and phase matching will be unchanged. However,
it should be easier to put the frequency shaping outside the quadrature
phase network, since it can then be guaranteed to be identical for both
channels. Leave the quadrature network all-pass; if you wish, shape its
absolute phase to compensate the frequency-shaping filter. At least, that
is how I'd approach it if I were constrained to do it analog.

The exact reference is FAR 91.21. This section prohibits the use
of all portable electronic devices except voice recorders, hearing
aids, pacemakers, electric razors, or (and this is the important
part) "any other portable device that the OPERATOR of the aircraft
has determined will not cause interference with the navigation or
communication system of the aircraft on which it is to be used."
I capitalized operator because most commercial airlines have rules
regarding operation which take it out of the pilot's hand.
However, private operations are normally dictated by the
pilot-in-command (I operate from my aircraft quite often).
It is also important to note that this rule only applies to aircraft
being operated commercially or on any aircraft being operated IFR
(instrument flight rules).
Hope this helps. You will see many claims about operating in the
air on commercial aircraft with "no harm done". In the USA, this
is ILLEGAL on all of our domestic carriers. Also, taking the
stance that "it never caused any problem when I did it, so it must
be ok." is looking the problem with blinders on. Nearby RF
transmission affects all receivers, if not by direct interference,
then by desensing the front ends. 99% of the time, there will be
no harm done, but that 1% can be deadly in an aircraft! Talk to
an airline pilot about those laptops and CD players that are now
banned by some airlines during departure and approach. Even the
low amount of RF from those devices can cause havoc in the cockpit.
By the way, the rule is a FLIGHT rule, therefore there is no
restriction on operation in and around airports (other than the
normal interference rules).
Hope this helps.
73,
Pete WB0FEW
PS. Cellular phones are illegal to use in the air by FCC
regulation. There are NO exceptions to that rule in the USA.

SB SAREX @ AMSAT $STS-59.002
STS-59 SAREX Flt Info
Launch of next SAREX mission imminent
The next Shuttle Amateur Radio Experiment (SAREX) mission is ready for
launch at the Kennedy Space Center in Florida. This flight, designated
STS-59, is scheduled for launch on Friday April 8 at 12:06 UTC. Weather
conditions could cause the launch to move forward or back by one hour.
STS-59 will carry Jay Apt, N5QWL and Linda Godwin, N5RAX on a nine day
mission which will include packet radio and some voice operations. A SAREX
fact sheet, courtesy of Jay Apt, the ARRL and AMSAT follows. Note that
during this mission, the JSC ARC, W5RRR, expects to retransmit NASA Select
audio on AO-13. The planned downlink frequency will be 145.84 MHz. In
addition the JSC ARC crew in Houston have set up a dial-in BBS which is now
in operation. Orbital elements will be available on this machine
throughout the mission. The phone number for the BBS is (713) 244-5625.
Please use 9600 baud or less.
SAREX FACT SHEET - STS-59
WHO: Space Shuttle Endeavour crew
WHAT: Talk via Amateur Radio with students and radio amateurs on Earth.
WHERE: Earth Orbit. Altitude 220 kilometers, with radio coverage in
latitudes from 70 degrees North to 70 degrees South. This flight
is in one of the lowest altitude orbits ever flown by the shuttle,
so pass times will be shorter than usual.
OPERATORS: Dr. Jay Apt (N5QWL) and Dr. Linda Godwin N5RAX.
N5QWL is the commander of the Blue Shift aboard Endeavour and will
operate the shuttle systems during the "night" shift, while
N5RAX is the Payload Commander, responsible for overall
operation of three large radars in the shuttle's cargo bay
during the "day" shift.
WHEN: April 8, 1994 at 12:06 UTC (9 day mission)
WHY: As part of the Shuttle Amateur Radio EXperiment
(SAREX) component of the STS-59 mission.
SPONSORS: The American Radio Relay League (ARRL), The Radio
Amateur Satellite Corporation (AMSAT) and
The National Aeronautics and Space Administration
(NASA).
SAREX MODES: FM Voice and Packet
VOICE CALL SIGNS: N5QWL and N5RAX
PACKET CALL SIGN: W5RRR-1
SAREX RADIO FREQUENCIES:
Voice Downlink: (Worldwide) 145.55 MHz
Voice Uplink: 144.91, 144.93, 144.95, 144.97, 144.99 MHz
Voice Uplink: (Europe only) 144.70, 144.75, 144.80 MHz
Packet Downlink: 145.55 MHz
Packet Uplink: 144.49 MHz
Successful QSOs on voice will be facilitated by using
standard international phonetics for your call sign.
The crew not answer any stations using non-standard
phonetics. Use your entire call sign -- the crew logs with an
audio tape recorder. Do not use the Shuttle call sign --
passes are very short, and the crew wants to work as many
folks as possible.
If you can, decrease your radio's deviation to 3 KHz (most are
initially set at 5 KHz) and compensate for the Doppler shift. If
you cannot, wait until a minute or 90 seconds after the Shuttle comes over
your horizon to transmit -- that will put you within the SAREX IF. The above
applies to both voice and packet.

OPERATIONS NOTES:
If you have a packet QSO number issued to you by the
robot, don't try to get another one! The on-board
program drops the duplicates anyhow, and all you
are doing is making it harder for the other folks.
A QSL card will be issued if you appear in the "heard"
list on the TNC.
N5QWL will be asleep over most USA passes, and N5RAX will
be busy with assigned duties for most daylit US passes, so
if the sun is up, try SAREX on packet. The Shuttle crew
will try to work voice (1) when we are not otherwise engaged,
and (2) at night or when the ground is cloudy (we are
generally busy taking pictures of the Earth during clear
daylight passes).
If Jay Apt can get to it, he will activate the SAREX about
3 hours into the mission.
QSL via: ARRL, ATTN: STS-59 QSLs, 225 Main Street, Newington, CT 06111,
USA. Include a self-addressed stamped envelope (SASE). Non-US
stations include a self addressed envelope with $0.50 of US
postage affixed or appropriate IRCs. Include the Callsign worked,
Date, UTC, Mode, and Frequency. For packet contacts, include the
QSO number issued by the robot. SWL QSL's: Include the Callsign
heard, Date, UTC, Mode, and Frequency.

Subject : Need info on creating a Packet Repeater
Looking for information on designing and implementing a
Packet Repeater (not a digipeater, an actual dual frequency repeater).
I would also like to hear from anyone who has a packet repeater up and
running.
