I'm looking to buy a used UHF FM amplifier for my HT. Ideally it would take
about 3-4 watts in and put out about 20-30 watts, but I'm open to suggestions.

If you have such a beast for sale, please contact me at the e-address below.

Thanks,

  Well, yes, there's that too.  But mostly what happens is that the
electricity that leaks out from A and B drips over the sides and then 
it shorts across the concrete.   If you put wood under the battery it 
soaks up the electricity before it can get to the concrete.

  I suggest that this topic be included in the Extra class tests, it's
pretty important that hams know about it.  It's knowledge like this
that distinguishes us from the CB types - they think the electricity
leaks out at C and D - can you imagine anyone being that stupid?

  And to those doubters who don't believe that concrete is a conductor -
I have heard that just about every building that is struck by lightning
has concrete in it somewhere, you can't ask for better proof than that.

I found the fm repeater at 145.987, +-or - 3khz for doppler.... maybe this is
why they put it between two channels.  The simplest rigs will be using vertical
antennae, with more pronounced doppler shift (closer to the horizon).   I hear
the beacon around 145.820 when it fades in.

My wife and I purchased two of the Standard 168As at Dayton. We surveyed
the Alinco, Icom, Yaesu and Kenwood little units, and we liked the
combination of features in the Standard the best. Like the previos guy,
there are good and bad -

Good - most everything. Easy to program. Solid buttons, knobs, good
sound. Rugged. Logical placement of controls. I can key all the digits
of the frequency, which is useful for the extended receive.

Bad - 1. My knobs don't keep turning, but I've found that if your hands
get sweaty, they'll slip on the rubber knobs.
2. The battery hold catch broke on my wife's rig, so it's in the shop at
the moment. Her mistake though.
3. Accessories are somewhat more expensive than other manufacturers, and
harder to obtain.
4. The power supply cord is positive on the outside of the ring, which seems
like a short circuit waiting to happen.

So, some problems, but the unit is very satifying and functional. We don't
regret choosing it over the Kenwood and the others. - Gary

Actually, very few radios operating with antennas INSIDE the car will work.
If you enclose a receiving antenna within a closed metal object (any shape),
NOTHING will get in.  Gauss' Law pertains to electromagnetic fields.  The
car is a Faraday shield, and the windows aren't usually very good "holes"
in the shield.

With outside antennas, the car can usually act as a good ground plane.

Eh?  How is that going to work.  The reason that 52* works is that
people happen upon these accidents who don't (and shouldn't) be
in the posession of a radio that can transmit in the police band.
The idea is that there are guys out there with ham radios rather
might happened across the incident before the police.

> Amateur frequencies help in communications emergencies, _not_

This is in disagreement with 97.1(a) which expresses the principles
of amateur radio to include "the value of the amateur radio service as
a voluntary noncommercial communication service, particularly with
respect to providing emergency communications."

> The distinction is when you can reasonably _anticipate_ the need

I don't disagree with you on this point, HOWEVER, the specific case
you are maligning is when you can't _anticipate_ needing the service.
No police force patrols the interstate with enough frequency that
someone other than the police is likely to come accross the emergency
situation first.  This is why many interstates have little emergency
telephones along them.  This is why we have channel 9 on CB.

> Vigilantism on amateur bands, even with the greatest intentions, doesn't
> seem to me to be at the core of Amateur radio.

My dictionary defines vigilate as a "volunteer group that supresses and
sumarily punishes crime."  What we are talking about here is summoning
aid in an emergency which doesn't quite fit that definition.  If I run
accross an emergency, I'm going to use whatever means I have to safely
assist the situation, be it through stopping and rendering assistance,
using amateur radio, or my telephone.

As an aside, it sounds like the WB1GOF * 52 works pretty well.  I can
tell you from having used an autopatch to report an emergency before
that it sounds like a much more effective approach than direct dialing
to the appropriate body through autopatch.

Yeah, I know about the contests at hamfests; what I want to know about are
the contests which McElroy participated in, which I gather were a much bigger
deal.  There is a typical-of-the-period picture of him surrounded by
trophies he had won.  I assume these were contests for commercial operators.

This got me to thinking about contests of skill for people in other
occupations.  It's been several years since I have read about a typing
speed contest - the last one I heard about was won with a speed of 130 WPM
or so.  Maybe there were shorthand contests for stenographers at one time.
The rodeo continues as a contest of cowboy skills.  You just don't hear
much anymore about contests where working people compete on their
abilities.  I'm not counting things like the Oscars and competition that
a professional photographers organization holds, nor awards and honors,
because in these things people are not competing against each other on
specific tasks.

I have heard the legend about concrete floors killing batteries for years ( I
worked in an auto parts store), and as best I can figure out, the only real
problem with concrete is that its cold, so if you store your batteries on it
during the winter, they will be colder than if you put a board or piece of
cardboard under them.  We store the deep cycle batteries for our boat on the
floor in the garage, and they hold up just fine.  The battery for my motorcycle
spends winters on a steel shelf in the basement; again, no problem.

Anyone who copied DOVE on a regular basis during the Polar Ski Trek a 
couple of years ago learned firsthand about Doppler shift and FM.
It doesn't matter what the actual transmit frequency is, since the only 
time the receiver is going to see that frequency is when the satellite is 
at the point of closest approach.

In practice, clearest reception may occur 10 KHz from the published 
frequency.

Still not convinced?  Tune in your favorite repeater and then tune your 
receiver up or down 5 KHz... you will likely be able to copy it just 
fine.

True!

Folks,
   Maybe this is a dimwitted idea, but why don't you just rewire
the power cords and sockets so their polarity is reversed? I
agree, though - It doesn't make any sense to put the positive
feed on the sleeve instead of the tip. Why can't manufacturers
agreee on a common standard for these things?
   However, for this to cause a problem with a negative-earth car
your portable/mobile would have to have a positive-grounded
chassis, which would be VERY unusual. Anyone with a positive-
grounded car (also very unusual and not made anymore anywhere!)
could have real problems, though.

If you haven't already, I'd suggest you pick up a copy of the ARRL's 
"ARRL Radio Buyer's Sourcebook". (ISBN 0-87259-345-2. ARRL # 3452, $15.00)
It's a nice collection of QST reviews which, IMHO, is a decent way of
becoming familiar with the features, performance, etc.

Certainly owner opinion counts very highly, so I hope you get some
comments here on the net as well. I too am in the market for used
HF rig, and I've decided the best thing to do is do a lot of reading
beforehand. Good luck!

My 4 watts on 27Mhz went over 2000 miles, and I have QSL's from England/Ireland

a lot on terrain, and the elevations above said terrain of the transmitters.

Given a reasonably flat terrain, I would say up to 100 miles.
