David Sumner
c/o ARRL QST
I want "my" ARRL to support the interest of Amateur Radio
Operators around the nation rather than taking excursions
into presumptuous areas of browbeating. Back off on the
callsign administrator issue.
On page 9 of the October QST (speaking on the tussle over
automated HF operation), you say "the danger comes when we
begin to believe that what we want to do is more important
than what someone else is doing." How about applying this
to yourself?
On July 26, 1993 the FCC invited applications for adminis-
tration of a callsign program from all qualified organiza-
tions. On pages 82 of October QST, you're quoted, saying
application by others "jeopardizes the program." What an
adolescent claim -- that's what the FCC asked for! The ARRL
appears as a pompous buffoon yelling "It's mine, all mine."
Everyone except the ARRL is relegated to "other fields" of
Amateur Radio, as if to say they're inferior to ARRL.
ARRL's what? General interest? In this case, ARRL's inter-
est is dangerously close to being only ARRL itself. In the
next issue of QST, two organizations are chastised for de-
fending themselves. Oh, please!
Why put all the eggs in one basket? You claim that diversi-
fication is bad, but you never sell why it's so terrible.
You looked to HF users and said "come on over, see with the
eyes of the other side, get along." I look at the callsign
issue and say to the ARRL: come on, see with the others'
eyes, get along.

Yeah, everybody tells me it used to be a real test.....some people even tell
me that getting a licence/callsign was for life....now we have pay money in
every year.
Our system is starting to copycat the US...they are even taking our 220 band
away from us to make peace with the FCC.

The state may have given me my drivers license when I turned 16 but
my *PARENTS* didn't let me take the *CAR* by myself for several weeks after..
Parents outrule the state :-)
I have nothing against a short wait between passing the test and getting
the license -- 1-2 weeks is OK but 6-8-10 weeks is bit ridiculous.

I can see that the action of receiving the entire note back from each of the
original recipients would create a real PYRAMID. That in itself is a pyramid
scheme and the return volume should raise considerable attention by anyone
having to pay for the activity.

it can be too much. for one bozo you might have a lot of other people you'll
hurt for whatever reason that may not know about the other transgression. for
that matter the "source" of such a post might not even know it was sent under
his name (someone else used a computer during a potty emergency or something).
i would think that just contacting the folks in charge of the place where the
chain letter came from would be enough for a first offense.
at least we're not suffering under a ton of messages about "<quote whole

Hmm... a friend and I were trying to spec out how one would do this on
the AV Mac DSP. Theoretically, it should be possible on any
directly-programmable DSP (or at least one you can send custom filters
to and receiver "pure" output at a sufficient rate).
On a similar note, has anyone taken the Baycom/PacketMac idea to its
logical conclusion, and done the *whole thing* inside the mac? My
friend and I were also spending some time specing out how would would
do this on a mac via either the sound i/o or one of the serial ports.
Anyone brew this one up yet?

The "gorilla" hooks are sold by Klein. Unless you really know
ropes, pay the money and get the Klein ropes and hooks already
assembled. Bending the rope to the hook is a non-trivial exercise
that if done wrong can get you killed.

I don't know where to get what you are talking about, but I have a
better suggestion. Go to a store which sells rock-climbing equipment,
and buy 2 "locking carabiners". These are d-shaped aluminum clips
which can be attached to a rope and clipped either to the tower, or
you can loop the rope around the tower and clip the carabiner back
onto the rope. They also have a ring which can be screwed over the
opening to lock them when you are at the top of the tower so they do
not accidentally unsnap. Last time I bought these, they were around
$15-20 each, and the ones I have indicate that their rated strength
before failing is in excess of 7,000 pounds. You may also want to buy
some "slings" which are pieces of 1 inch nylon webbing sewn into
loops. If you buy 2 of these of a suitable length and a third
carabiner to attach them to your harness, you can make quite strong
climbing "gorillas" (The slings also are rated at over 7,000 pounds
before failing). If you want more specific information, feel free to
drop me a note by e-mail.

This can be VERY cheap--I picked up, at a local ham club auction, a working
dumb terminal for $5.00. It works fine with a TNC, and gives newcomers to
packet, RTTY and the like a quick intro. I don't mind hauling it to a club
meeting for a demo, or lending it to somebody who wants to try packet and
see if he likes it before springing for a computer and TNC. I sure
wouldn't do that with my regular equipment.

I doesn't show up in the study guide or on our tests up here. And, the current
thought around here is that networks and newsgroups are lumped in as
reference material (resources).
Especially with the project by our government to link all the schools in
Canada to Internet....which includes the idea of providing a vast resource of
information by people all over the world of Internet.

Peter, DL6MAA, sent the following from Germany. Work is well underway on
PACTOR-2. Here are basic facts on the new protocol:
o Timing and frames similar to PACTOR-1 (effectively half-duplex
ARQ)
o Based on standalone DSP-PTC using the 68070 and DSP 56156 (40Mhz)
chips.
o 2-tone-DQPSK at 75/150 Baud (perhaps 8-PSK at 100 Baud rather than
4-PSK at 150 Baud)
o Bandwith: less than 500Hz at -30 db
o Well suited to fluctuating multipath channels
o MaximumSpeed: 600 bits/sec (4X PACTOR-1, and 15X AMTOR)
o Improved adaptivity and Memory ARQ
o Superior weak signal performance (5-8 db better than PACTOR-1)
o Independent of employed sideband (same as PACTOR-1)
o Automatic frequency correction (plus/minus 70Hz)
o Downward compatible to PACTOR-1 systems
o Compresnsive listen mode (both PACTOR-1 and PACTOR-2)
o System is not 'over sophisticated' (can be implemented on any DSP
controller with enough processing speed)
o A standalone PACTOR-2 controller should be out by the end of
1993.
o AFSK will be required for PACTOR-2. This will have an implication
for those using 500 Hz filters. (apparently some rigs can't select a
narrow filter when in SSB mode)

Clue: RF rectification isn't the broadcaster's problem. It's the cheesy
unfiltered phone's problem. That's also often true of other cases that
are blamed on "splatter" or other transmitter malfunctions. The problem
is often really in the receiver of the one complaining. It's really really
rare for a broadcast station's transmitter to be dirty. It's even fairly
rare for a ham transmitter to be dirty. Unfortunately it's not so rare for
a solid state ham receiver to be dirty, especially if used in the presence
of high signal levels with the RF gain turned up.

You're right, of course. I have other problems with that station,
which don't really bear discussion on the ham group, and just wrote
in anger after having heard their traffic report in my phone
having woken up on very little sleep to make an extremely important
overseas call. The moral of the story is not to get on Internet
without having slept at least 5 hours the night before.
Having explained RFI to my neighbors, and helped work to solve the
