You're forgetting those folks who, 10 to 15 years ago, were told that they
were not welcome on 2 meters, but that 440 was fine for their closed box. They
spent lots of bucks to get that box going. Now you're going to change the
rules on them in midstream and say, "Now, your repeater is a public utility;
never mind what we told you all those years ago."

Fairness in action.

"Needs to"? How do you define that? If you mean an emergency (and I use a
broad definition of the term), then I agree - and I don't believe that the
trustee of a closed repeater would bring it down, or run off, someone with an
emergency. The owners of the closed repeaters I use certainly wouldn't.
(Right, Jim?) "Wishes to"? Their wishes hold no more water than mine to
operate my equipment to the benefit of those people I wish; since it's my
radio, I get to control how it's used.

Unless their callsign is W1AW or K1MAN. In that case they'll just

From listening to a LOT of machines, I've come to the conclusion that for the
most part, the "most effective usage" would be for everybody to stay the
Hell off the air!

Basically, unless one becomes the Galactic Overlord of Amateur Radio, with
Ghodlike powers to dictate what is "righteous", there won't EVER be a 
consensus of how spectrum will be used.  Unfortunately, there are those who
assume they have this power.  And THAT is the basis of the problem.

Uhmmm, I haven't seen many FM receivers that have AGC.  They generally rely
on the high gain IF limiters to clamp things down to size, and to control the 
gain.

Desense is more of a saturation thing.  When a strong enough signal enters
the RF preamp stage of a receiver, the preamp goes nonlinear, and starts to 
saturate.  In the saturated condition, the preamp cannot respond to any tiny
signals, only the very strong signal.  This cuts the effective gain of the
receiver for the smaller desired signal.

Note, the AGC description of desense would be a perfectly valid possiblity in
an FM receiver that had an AGC, and was plagued with a strong signal that fit
within the IF passband of the AGC's detector.

I've wondered about keeping the antenna away from the head when Txing

antenna at the top of the tower.  Simply by talking into the HT,
the antenna is going to be fairly close to your head.  A remote
mike (ie: speaker-mic) usually means you're putting the RF into
your kidneys (ie: radio on the belt), which I guess is less harmful
than the brain, but it seems relative.

I did notice the warning in a manual for a Motorola HT to keep it away

Fred-

There is a Kenwood TM-741A, that comes with 144 MHz and 440 MHz, with a
place to plug in an optional third band.  Modules are available for the 28
MHz, 50 MHz, 220 MHz and 1200 MHz FM bands.

This info is from the Amateur Electronic Supply catalog.  Their price is
$699.95 for the basic radio, and $269.95 for the 28, 50 and 220 MHz units,
or $359.95 for the 1200 MHz unit.

The AES/Milwaukee phone number is 1-800-558-0411, if you're interested.

Someone asked for kit information for qrp rigs earlier this week or
last.

i just received a 'QRP Spirit' cw transceiver kit from OHR.  for those
of you who miss heathkit, this may be the kit for you.  it's not exactly
heathkit on the instructions, but the boards are double sided - plated
through holes - solder masked - solder plated - silk screened.  got it?
the boards were laid out using TANGO and have a ground plane.  one board
for rcvr and one for transmitter.  small board for keyer (single sided).

green solder mask and white silk screened component layout, just like the
heathkit boards.  this things are a beauty IMHO and i've built just about
everything that heath made and a&a and oakhills and mfj and mxm.  it's not
that i've got that much money, it's just cheaper than therapy at $100/hr. ;-)

anyway, specs for the rig

o  single band CW transceiver, for 80, 40, 30, 20 or 15 mtrs.
o  iambic keyer included using 8044ABM chip
o  superhet rcvr using diode ring mixer (TUF-1) and RF preamp
o  4 pole crystal ladder filter followed by on board audio filter
o  switchable AGC circuit with manual RF gain control
o  2 watts audio output
o  VFO tuning with 8:1 vernier covering 100KHz and RIT (+-800Hz)
o  QSK without relays  !!!!!!! my #1 wanted feature in a rig
o  5 watts out
o  4" X 6 1/4" x 6 7/8" at 47oz.
o  priced at $198.95 for the kit

assembly instructions (21 pages) are not the detailed type that heathkit
builders are used to.  there are no step by step instructions with
illustrations showing where each component is located.  i personally find
this fun, challenging, and forces one into a more thoughtful and careful
assembly procedure.  remember, patience is a virtue.......

i should have it completed by saturday.  those of you in the southern
region of the US of A, listen sunday morning around 9:30am 7060KHz.  i
should be there.  p.s. don't bring the linear amplifier, PLEASE.  ;-)

i am not an employee of or associated with oak hills research.  just another
happy customer.  i should have the QRP wattmeter by next week also.  email
me if the above doesn't answer all your questions.  get catalog by sending

I saw the R9000 at the Oklahoma Ham Holiday, last Summer.  It was absolutely
full of lots of great features.  Unfortunately, it was also full of lots of
heat.  My only real complaint about Icom equipment is that there has not
been enough attention to the heat problem when you consider the engineering
sophistication and cost of the products.  I own an R71A and R7000 and have
had a number of pesky problems with both receivers.  As far as I know, every
one of those problems has been caused by heat dissipation deficiencies.
If Icom can learn to make frequency displays and power supplies that don't
need almost constant attention, they will really have something to be proud
of.  I have joked that the electrolitics and IC voltage regulators in the
R7000 should all be in sockets since they go bad about like vaccuum tubes.

	By contrast, I have a Regency 50-channel scanner which I bought in
1983.  It is almost room-temperature, to the touch, and I had never had the
case off of it until just a few days ago when I had to give the volume and
squelch pots a shot of WD40.  Now that's what I call good design.

I want to get a packet TNC and I can't decide which model is best for me.
The recommendations I've gotten thus far run from the Tigertronics/Baycomm
setup to the KAM All-Mode unit, which is quite expensive for my current
tasts.

Having an all-mode unit might be nice, but I wonder if I'll *really*
use all those features in the long run, aside from playing with them.
So, in a nutshell, I think I'm looking at a lower-end model. The 
Tigertronics looks attractive and received a pretty glowing review
in December's 73 magazine and this has piqued my interest in the unit.
Others have mentioned that it might not be the most flexible unit, so I'm
a little wary, though for what they ask for it (<$80 w/software) I think
it might be a good starter.

What do you folks think? Please email me, if possible, and I'll summarize
for others interested.

Thanks.

Back in the days of germanium transistors, point-contact diodes and 300W 
soldering irons, overheating could be a problem.  But most modern
components should need no heat-sinking so long as you use a small-wattage
(like 35 W ro so) iron.

That's true, but it's also true that most packet groups are sparse
enough that high site nodes are required *anyway* to maintain connectivity, 
and they also serve as a single point failure *and* as a magnet for congestion.
Therefore these arguments apply equally to them. The fact is that a repeater 
just works much better than a high site simplex node for packet.

If you stick with just home stations and multi-hop links, then you're
generating even more congestion since each packet is transmitted multiple
times. Home sites are unfortunately not engineered to be non-interfering
cells. And one home station shutting down can fragment the network if it
is the only link between two subnets. That's very common in rough terrain
with sparse networks. The channel delay of multiple hop transmissions also 
turns a slow service into an infuriatingly slower service.

Repeaters for packet should best be thought of as large, controlled
coverage cells. Linked by a high speed backbone, they offer high
thruput while minimizing the interference common to simplex networks.
