The callsign is extremely relevant, which is why I am asking. But you seem
more inclined to argue and reject those trying to help.

To some end. Then you get serious and purchase a pair of crossed 
log-periodics and a hybrid coupler to cover the span.

But on TV, it's all horizontal or circular/elliptical polarization, so 
you can eliminate one of the antennas and the hybrid coupler. 

And if you want omnidirectional coverage, you build a large metal box, 
and place one log-periodic array on each face, and then phase those 
together using a series of hybrid couplers.

Well, I don't remember the thread, but if you are using a mobile amp in
repeater use, then folks were right to call you on it. You should
consider yourself lucky you got what you got out of it.

And since there is no reason to turn down the deviation of an HT600 to
+/-2.5 KHz, since they won't do part 90 narrowband, and there's no
narrowband on the ham bands (except 900), there's no point explaining it.

And you better start dealing with your part 90 gear, unless you're sure
you can replace them all and get them in to users hands in a matter if
days or weeks...most people in part 90 will have trouble getting it done
in years.

  Hi Don,

  Early tube-type repeaters used large relays to key the transmitter. When 
someone keyed and unkeyed the repeater the result really was a loud "kerchunk" 
at the site. It led to what we now call "courtesy delays" -- the idea being if 
there was another transmission soon after the first the transmitter would not 
have to drop and pick up again. It saved tubes as well as relays.

Hey folks,

My repeater whole-cabinet fan threw the bearings and now sounds like a diesel 
engine and turns maybe 500 rpm.  Anybody know where I can get a replacement?  
It's a Comair Rotron Major 6.75" 230CFM fan on 115V 30w.  All the dealers 
listed on Comair's site are out of stock w/ no backorders allowed.  Anybody got 
one in their junk box?  I really want to avoid hacking up sheet metal and

My VX5R handheld does AM over much/most? of it's receive coverage.  So does my 
Icom IC2350 mobile rig.  The aircraft band should work well, but there's 
nothing magical or special about sniffing for noise there.  I like to work near 
where my portable beams work properly (in the ham bands) with predictable 
patterns when tracing down noise, so I use empty channels within 2M and 70cm, 
listening on AM.

I've often found it useful to move to 70cm as you get closer to the source 
because it is easier to get a good bearing on the noise.

Paul,

Actually, if you're near enough to the airport, you should be able to hear the 
ATIS (Automatic Termininal Information System) broadcast. It repeats 
airfield/weather information continously. That'd be a constant (although 
perhaps not weak) signal in the aircraft band.

A special area of the fleamarket is dedicated to the clubs. Club spaces are

I'll be damned though if I can find the application form for club spaces.

If anyone is interested in pitching in, RB can get 4 spaces for use of list

Doug,

I use "Penetrox A"R (made by Burndy Electrical) to assemble antennas and
such. It's available from ham sources (AES, HRO, etc) or commercial vendors
(Tessco, Hutton, etc).

I'm not sure of the conductivity of Lithium Grease, but Penetrox has a known
level because it is primarily Zinc suspended in a petroleum base...  As far
as being weather resistant, it still gets all over everything (including me)
each time I service the antenna - and mine has been up 7 years now.  ;-)

Paul,

Actually, if you're near enough to the airport, you should be able to hear the 
ATIS (Automatic Termininal Information System) broadcast.  It repeats 
airfield/weather information continously.  That'd be a constant (although 
perhaps not weak) signal in the aircraft band.

Ah! Somehow that hadn't occurred to me. The president of our club is

I guess there are no weak, constant signals in the aircraft band (?) 
but maybe it's not necessary. I will try climbing the tower with it 
and see if it does anything when I move or vibrate guy wires and 
other hardware with the repeater transmitter on of course. It's 
possible the aircraft handheld will just be desensed by 2 meter RF 
and unable to hear the noise (?) but it will be interesting to see

RE: [Repeater-Builder] 220 Repeater Power Amp

[Mike Morris WA6ILQ]

RG142 uses a steel core with copper plating for a center conductor.

RG400 is the exact same stuff but with a twisted stranded center
conductor, but each strand is silver plated before twisting.   The
stranded center makes it a lot more flexible and useful.
It's good stuff.

LMR (any three or four digit number) is crap.
Motorola says so 

Andrew says so

the engineering is sound and it's actually worth reading)

Get Rid of that crap cable your using..
 I only useRG 214, and or superflex for my

line(power amp/preamps), and the 
duplexer.  Mosly 1/4" superflex becuase I got 
lots of it. In a pinch I will use RG-142... 
Never use that 400 or 9913 garbage..

That’s the  model I am using now.   I have 
some other issues to study before changing to 
another amp.  But hearing that someone is using 
this same amp is encouraging.  Like I said

Aircraft handhelds are AM in the 120MHz region.   Some handheld
scanners do aircraft AM just fine.

I remember seeing a Bearcat handheld scanner many years
ago that "knew" that 30-50 was NFM, 54-72 is Wide FM,
72-76 is NFM, 76-88 is WFM, 88-108 is WFM, 108-136 is AM,
136-174 is NFM, etc.  The unit, however, would allow you to
force the unit into any modulation method on any frequency.
I used one of those to "prove" to the FM CE that his FM
transmitter had a very weak spur on a 440 repeater input...
dialed up the input, switched to WFM and voilla - you heard
the BeeGees playing "Staying Alive" at the same time that
the FM station was playing it... one minuscule tweak on
the transmitter and it was gone.

A unit like that would be very handy for having on your belt
with an earpiece in your ear while you shake and hammer
on the tower hardware.

Then there are the aircraft band handhelds made for airport
use, or for pilots as something to toss in the flight bag and
use as "last resort, my entire panel has failed" radios.

Some of those, like the early Icoms go out of band into the
ham band quite nicely.

I wish I had been at the local ham swap meet a few months ago - an
acquaintance of mine picked up an Icom aircraft handheld in the
IC-04AT package (don't remember the exact model number) for $10,
but it was less the battery and labeled "doesn't work".  Once he was
out of sight of the seller he slid the battery from his IC2AT onto it and
it powered up just fine, but with no speaker audio.  A few stalls down
was a guy selling cheap earplugs, like what you would use on a 1960s
transistor radio.  We plugged in one of those and the Icom worked just
fine... it needed a new speaker.

So keep your eyes open.  AM VHF radios are out there, and some will
go out of the aircraft band and do ham 2m and make great units for
having on your belt while you shake and hammer on the tower hardware.
