The question is who is being deluded, those of us who've worked
240+ countires in a couple of years with one, or those who who just
plain "know" it doesn't work any good...  If it's me, I hope it
continues a while longer.  I'd love to make Honor Role with my

Subject: Amps - Pounds relationship
To: [e-mail]

While reading a recent ad for a well-known power supply company, I noticed
an interesting relationship between the maximum current rating of the
supply and the shipping weight; they seemed almost equal. The linear
regression of the 42 data points (different power supply models) from the
ad is:

Weight(in lbs) = (.832 * Current(in amps)) + 3.52

The coorelation coefficient is .96, so the fit is pretty close. So, if
you're buying a power supply, you can guess that the shipping weight in
pounds is about equal to the maximum current rating times 0.8. Ain't
science grand?

        is pretty much a dummy load.

I strongly recommend a Larson "Kool-Ducky". I use one on my TH-78 rather
than the stock dummy load. I ran some comparison tests and found better
receive and transmit performance with the Larson antenna. Test methodology
was to get into a fringe area with the stock antenna, then switch to the
Kool-Ducky. Fringe became full quieting every time. :-)

The Kool-Ducky has more capture area than the stock dummy load on either
the TH-78 or the FT-530. I have not seen the stock antenna on the Alinco,
but I expect the same results.

As to loosing the antenna, are you clipping the HT to your belt and wearing
a fanny pack that rubs the connector? I found I was loosening the BNC when
I swing the fanny pack around to get out my wallet/keys/etc., then dropping
the antenna as I walked.

I have a Comet CH-72S, it is much better than the duck I got with my IC24at.
But it seams to work about the same as the one I got with my FT-530(Yaesu).

The one bad thing about the Comet is that it is 15inces long. They say
size doesn't matter, but it sure does make it difficult to put in the
glove box with out bending. :)

Subject: CCP SRC-10 Controllers
To: [e-mail]

A friend and fellow Ham has a group of repeaters here in the
Bay Area. He has been using Creative Control Products SRC-10
controllers with good success. Unfortunately it appears as if
CCP has gone out of business. They *don't* owe him money but
he'd like to get access to some additional units, spare parts,
bare boards, SW, etc. for long term support of his system.

The last address he has for CCP is in Grand Junction, Colorado
but they aren't answering mail and the phone is disconnected.
He contacted '73 Magazine (where they used to run ads) and was
told the owner "chose to get out of the Ham business". (I can't
imagine why?)

So any information about the company or SRC-10 designs would
be appreciated.

Subject: Contest Question
To: [e-mail]

Here's a hypothetical (maybe not!) question about contest operations for some
solicited discussion --

  Wanting to participate in FD or another contest and not having a station set
up at home, I arrange with a ham friend to use his station -- rigs, tower,
beams, power supply, etc.  For the duration of the contest, I operate from his
QTH, sleep on the couch and eat my meals from his 'frigerator  (he is REALLY a
nice guy!)  I rack up the contacts and have a great time .... using MY
callsign, not his.   Question: should HIS call, not MINE be used; should the
call be MINE/HIS or HIS/MINE; or does it really matter?  (Afterall, when the
contest scores are published in QST is it the OPERATOR or STATION that gets the
recognition?)
   Is this a question of propriety or legality?

Subject: hf radiation
To: [e-mail]

Research has shown no evidence that there are harmful effects to
nonpolarizing electromagnetic emmisions in the hf bands.

Picture, if you will, the average ham station, running 200 PEP watts for one
hour per week.  Compare this, if you will to a commercial broadcast AM
station running 50,000 watts 24 hours per day.  Now measure the total
level of electromagnetic emissions received.

Even with the geometrically higher levels of emissions put out by the
broadcast station, research has failed to document any adverse health
effects to people living immediately next to the broadcast station's towers.

When it comes to UHF signals in the microwave areas, care must be taken,
but these are not the frequencies (about 1000 Mhz) used by ham operators.

Subject: Mobile HF Noise Problem
To: [e-mail]

I'm having lots of fun mobiling with my new Kenwood TS-50 and 20 meter
HamStick antenna.  My only problem is engine noise :-(

I have no alternator whine but I do have what appears to be ignition
noise (the sound is rough and varies with engine speed, at low speeds
there are distinct pops).  It definately comes in through the antenna
and not through the power leads.  It runs about S5 to S7 on the TS-50
meter.  The TS-50 noise blanker is effective against it at idle but
not at highway speeds.

My car is a 1993 Plymouth Acclaim 4 cylinder.  The body seems well
bonded together electrically because I measure fractions of an ohm
resistance between various body panels (including the trunk lid) and
the negative terminal of the battery.  The fused #10 power leads from
the TS-50 are connected directly to the battery.  My antenna is
temporarily on a mag-mount on the trunk lid.  Connecting a heavy wire
from the mag mount to the body does not reduce the noise.

So, HF mobile elmers, what should I do to reduce this noise?  I'm sure
there are tons more stations to hear and work....

Thanks and 73

Subject: Mobile HF Noise Problem
To: [e-mail]

Hi Gary:

I am not an HF mobile expert, but have done a bit with radios that did
not have noise blankers.  I will just tell you what did help me to reduce
the "hash" I got from the car.  (I never really faced the standard
ignition noise, the fast "cracking" noises.)

I found that, magically, a very short lead from the body ground to my rig
helped, even with direct connections to the ground lead of the battery and
at the antenna.  The difference was amazing.  (Of course,  you probably
have already done this :-).

I have a friend with a Volvo that has an electronic fuel pump in the
back of the car (near the antenna), and who found that to be the major
contributor to noise.  He did some bypassing of the lines there and cured
the problem.

I have had friends use coax to replace their spark plug wires, or use
braided shield to run over the car spark plug wires, and to otherwise
shield the auto electronics boxes.  They claim some improvement.  I suspect
you could reposition the mag mount for your HF antenna and see if you
can "locate" the noise in general.

Best of luck.  I like to mobile, too.

It was an issue which came out this spring. I was enthused to see it until I
read it.
One of the highest rated devices was an "in the ear mike/earphone" rig.
I own one of those and borrowed another. USELESS!
They are VERY sensitive and pick up every bit of noise, wind, engine, gear
shifts, passing trucks, ect., and I ride a quiet motorcycle.
I used it in a resturant and the person I was communicating with said he
could hear conversations elsewhere in the resturant comming over the
air while I talked!

I have found something which does work, a new throat mike rig from an outfit
called Genisys (sp?). It picks up ZERO noise. It's high freq. response is
limited, but it gets good reports from people I talk to. They often express
suprise when I mention that I am motorcycle mobile. It has an attached
earphone which fits well in the ear.
I still think I would prefer a speaker or built in helmet phones, just for
conveinience.

Post if you find any other useful motorcycling/radio goodies.

I've used the headsets and mic element used in the NADY
motocycling intercoms successfully for years. I don't find the
ear buds stay in all that well, but the little speaker units for
the open face helmets work decently. I usually modify them to
remove the boom, although that works fine, and use the microphone
from the full face version - essentially creating a hybrid with the
open face speaker box and the full face mike unit, and rewire the
cord so it plugs directly into the control box from my ICOM style
HT (mine is actually an alinco dj580, but the hs-10 box works fine
with it). The most important thing is to turn the gain on the mic
*way* down, barely off the peg. I get very good comments on the
sound ("quieter than your car") and I can hear well. I usually use a
pair of foam earplugs to reduce the helmet noise anyway and save
the hearing, and the little speaker can drive hard enough to be heard
well above those with the shield up.

Last I looked you could get the replacement speaker/mic sets for the
NADY intercoms in the Dennis Kirk catalog for about $20/each.

Hope this is useful to you.  And remember, traffic is a non-maskable
interrupt! :-)

Subject: Neat FD Antenna
To: [e-mail]

   At the Panther Amateur Radio Club's (PARC) Field Day, we found that
an automatic antenna tuner is good for more than just loading up short
mobile whips.

   Our main FD antenna was a full-sized 80M Zepp dipole.  One end of the
antenna was attached to the roof of a 10 story building, the other end
to a tree below.  The antenna was fed with 300 ohm twin lead that
eventually connected to a 4:1 balun.  For an transmatch, we borrowed
an SGC-230 automatic antenna tuner.

   This made for a great combination.  The SGC tuner had no problem at
all producing an acceptable SWR on 80-20M (we did not try 15 or 10).  We
didn't waste any time or battery capacity fiddling with a transmatch.
This also permitted our less-experienced hams to easily switch bands
without fiddling with a manual antenna tuner.  We made 479 contacts with
the antenna, most of them at 50W CW, so it seems to have put out a great
signal.
