So, folks, now that the Commission has recognized "high speed message
forwarding systems", how long do you think it will be before we HAVE
any such?

I am trying to locate the correct address and / or phone number
for OK1IA (now OM1IA ? ) , Pavel Horvath. His Callbook address
- P.O. Box 44, Bratislava, Slovakia no longer correct.
He is the QSL manager for 3W8VL. I recently sent a registered
letter to the Callbook address listed above. The letter was
returned 6 weeks later from Slovakia stamped "Jedotlivo kartovane"
and "Retour". I am guessing "retour" means return and "jednotlivo
kartovane" might mean 'no longer at this box' . Is this correct ?
If you have a QSL from either OK1IA, OM1IA or 3W8VL or other
information on how to contact Pavel Horvath or others regarding
a 3W8VL QSL card, please contact me.
Many thanks,

There are so many hams involved in Linux development and use that it
makes sense that we should be exhibiting/selling Linux Journal at the
Dayton Hamvention. But, we didn't have a Linux Journal when it was
deadline time for Dayton.
Anyone out there have a table and an interest in being our
representative? Probably a good chance to promote Linux plus
make some money.

Okay -- here's The Deal (tm): According to the FCC, you can operate your
amateur radio anywhere you want (including on an airplane), but they point
you to the appropriate FAA rules. (Vague paraphrase of Part 97)
The FAA has more serious words on the subject (and I quote)
--------------------------------------------------
FAR Part 91.21 Portable Electronic Devices
(a) Except as provided in paragraph (b) of this
section, no person may operate, nor may any
operator or pilot in command of an aircraft
allow the operation of, any portable electronic
device on any of the following US-registered
civil aircraft:
(1) Aircraft operated by a holder of an air
carrier operating certificate or an operating
certificate; or
(2) Any other aircraft while it is operated
under IFR.
(b) Paragraph (a) of this section does not apply to --
(1) Portable voice recorders;
(2) Hearing aids;
(3) Heart pacemakers;
(4) Electric shavers; or
(5) Any other portable electronic device
that the operator of the aircraft has
determined will not cause intereference
with the navigation or communication system
of the aircraft on which it is to be used.
(c) In the case of an aircraft operated by
a holder of an air carrier operating
certificate, the determination required by
paragraph (b)(5) of this section shall be
made by that operator of the aircraft on
which the particular device is to be used.
In the case of other aircraft, the
determination may be made by the pilot in
command or other operator of the aircraft.
--------------------------------------------------
End quote -- begin interpretation & explanation
Applications
1) If your buddy takes you flying in his PA-28R, you can
get his permission, as Pilot In Command to operate your kilowatt
2m station, if he determines that doing so will not interfere with
his communication & navigation equipment.
2) If you're flying to Florida on AirWorst Airlines, you may NOT
operate any transmitter or receiver ever. The pilot does >NOT<
have the authority to allow such operation. (See FAR 91.21 (c) --
The important definition is "operator" which is NOT PIC)
3) Some day, perhaps, HamFriendly Airline will acquire an operator's
certificate, and offer a while-you-wait TSO program <g>, in which
case the Operator (license holder) CAN authorize the operration of
your portable electronic devices. But don't hold your breath.
Two other things:
Believe this. I once took some various RF gear aloft with a
friend, and we evaluated the effect of operating the gear on VOR
reception: A cheapie R/S 'Listen to the airplanes' receiver, when
tune 10.7 Mhz below San Jose VOR, succeeded in dropping a red
flag, indicating loss of signal, from about seven miles out.
The IC-24 dual-band HT had no effect during receive all across the
2m and 70cm Ham bands. During 2m transmit, it caused considerable
needle wobble on the VOR. Operating the R/S Airband receiver
while close to the airport (on final) caused about 40 degrees of
error on the VOR signal. All of these tests were conducted while
operating VFR, of course.
Under no circumstances should you operate a cellular mobile
telephone while aloft. The frequency reuse only works (and I use
the vaguest sense of the word "work") when your car stays on the
ground. Going up to 5,000 feet would cause your signal to swamp
every cell-site in a major metropolitan area, and is expressly
forbidden in the appropriate FCC regulations.
However, I don't believe there is any such prohibition against
Sensible Mobile Telephone Service (IMTS). I don't have the
appropriate parts, so I don't ACTUALLY know, but I -- errrr -- an
anonymous friend has gotten great signals out of the San Jose
terminal as far south as San Luis Obispo.

For some reason, the "third method" of SSB generation invented by Weaver has
never caught on. Perhaps part of the reason is the fact that the suppressed
carrier comes out right in the middle of the audio passband. Even with
40 dB of carrier suppression (typical with diode balanced mixers), people
might find it objectionable because of the AGC action of typical SSB
receivers. (Which would make the carrier "pop up" during speech pauses.)
I have often thought, though, that the Weaver method would be well-suited
to implementation in a DSP, since you can get mathematically perfect
carrier suppression.

To: info-hams@ucsd.edu
Hello. I just bought a Hustler super resonator for 40 meters and was
surprised to find that it did not fit my mast. It seemed like the thread
was different. When I tried to screw it on the mast, it was very "wobbly"
and would not seat properly. After tightening as much as I dared, there
was still a gap of about 1/4" with threads showing. I have five other
resonators (standard not super) that all work fine with the mast. Anyone
have any thoughts on the subject?

True. None of the above modifies the fact that it is still illegal

I totally agree. Even more aggravation is listing these huge directories of
ham radio files. Both of those psot toally violate netiquette. These belong
in a data base at some location with a pointer. This newsgroup is the only
one I have seen that has this type of post happening consistently. The
format of the hams on usenet is not even very good. The directory listing
is not too useful because it has very little descriptive information. I set
a private message to the directory lister but never got a reply.

Yep. APRS (Amateur Position Reporting System) by Bob Bruninga
(WB4APR) software has it as an option along with GPS, Loran C,
and direction finding info. The weather station used is the
Ultimeter II from Peet Bros Company (800)USA-PEET. About $180.
The software is available as APRS403b.ZIP and XTRA403.ZIP on
oak.oakland.edu, ucsd.edu, or bbs at (410)280-2503.
APRS software provides a map display of packet stations lat/long
position along with whatever information is broadcast (bearing,
weather, comments). Weather reports are broadcast as beacons.
Inquiry capabilities are built it to get the latest reports.
There are enough features to keep one busy for quite a time just
discovering how it works and what can be done. It's very impressive.
Here in Santa Cruz, we've been playing with APRS for about 2 months
and are setting up an automated DF system.
Note that the disribution software is shareware and requires
a $19 registration plus $9/ea for GPS, LORAN, WX, and DF routines.
Discounts for club orders of 10 or more.
