No, it's not a joke. Wayne Green seems to believe he has found the
cure. He editorializes about it in the same column in which he
expounds the virtues of cold fusion. And psience. Well, anyway,
he's been on that toot for several months now.

Perhaps his next 'small business venture' will be a medicine show
and carnival.

The problem is in the alternator.  Somewhere around 30-40,000 miles
something will let go in the regulator.  In addition to the increased
noise, you will notice an over voltage.  Instead of the nominal 13.1 volts,
you will get something like 14.x volts.   The car will still run good,
and for a long time too.  You may notice a slight glow to the "alt" light
on the dash board at night.  That is your cue that something is wrong.

I've had this happen twice, on my Citation, (which was an early model run
and had the predecessor alternator as on the Caprice), and on my old
Dodge's heavy duty alternator.  BTW the Citation kept going until I sold it
at 75,000 miles, but the Dodge alternator conked out on the highway at
55,000 miles.

I think the rule reads "one year" which would be Nov. 7 to Nov. 7.  "Twelve
months" or "365 days" could give different answers.

Hello --

I am the coordinator for the Ham Distribution Net and have been
posting notices of new files to the newsgroup for a couple of months
now. It appears that files arriving at ftp.fidonet.org and mirrored

HDN is looking for an ftp site that is willing to mirror either
ftp.fidonet.org or ftp.halcyon.com as new files arrive and allow

Sorry Carl, didn't mean to slam Heathkit. My point was that in any
normal distribution of customers, by definition, there will be some on
each end of the spectrum outside the three sigma limit. Experiences
outside the three sigma limit ON EITHER END of the normal distribution
are not good points of reference. My experience with six Heathkits was
worse than my experience with four Ramsey FXs but I am only one point on
either distribution and I don't know exactly where either of my
experiences fall on the plot. We tend not to hear from customers with
average experiences.

I have a 1987 Acura Integra.. I run a Ten Tec Argonaut 509 both SSB adn CW.

I had some ignition noise problems at first.  I rewired all the power directly
to the battery and purchased the Radio Shack noise suppression kt (think
about $15). Seemed to take care of the problem. Still get noise from over
head power lines.. but on most highways.. no problem

If his Acura behaves like my '88 Honda Civic Wagon does, replacing the ignition
wires won't do a thing for him.  Nor will replacing spark plugs, grounding the
hood, etc.  I've been trying for almost 2 years now to de-noise my wagon.  The
igniter replacement I had to have done back in September (car death) didn't help,
either; it may have hurt a bit, I'm not sure anymore (I'm somewhat used to the
noise now, so it would have to change rather drastically for me to notice).

My next car's gonna be something non-Honda...  :-/

 A Ni-Cad may not leak at 45 celsius, but the self discharge
rate will be so high that the battery pack will be useless when you
need it. You would have to recharge the battery pack daily. If you
want a radio with instant emergency usefulness, consider a
walkie-talkie with Lithium Batteries. It will have a shelf life of
about 10 years.

 Failing that, keep the radio in the trunk, keep a couple of
packs with alkalines in the glove compartment and use the batteries
somewhere else after 6 months. You may also keep a Ni-Cad pack in the
car, but it should be recharged weekly in the summer.

 Note that Ni-Cads are have terrible self discharge curves.
Sitting on a shelf, a Ni-Cad pack will be pretty flat after a month.
An Alkaline pack will be fine after 18 Months. The best batteries for
storage are Lithium. But they are hard to find and no company that I
know of currently makes lithium battery packs for walkie-talkies.

>Is this a concern that should keep me from storing an HT in my trunk during
>the summer months?  Anyone have any similar experiences or wisdom to share?

 The batteries and the electronics will be happier if kept
cool. I store Alkalines in the Freezer and Ni-Cads in the fridge -
right next to the beer.

I don't know of any reason why you can't take all the written tests w/o
passing a code test first.  You certainly can have written credit w/o having
code credit.

a long time ago this was not the case, but today there is no reason not to go
ahead and give someone a written.  having that credit can be an incentive to
get moving on the code.  I know I had extra written credit twice (the first
time a few years ago, i never got my code up.  the 2nd time, i did make it
after about 3-4 months....)

sounds like your VE team needs to get up to date.  I know we do written credit
only --

Someone said that between 30 and 225 MHz, transmitter spurs are limited
to 60dB down from the carrier. That is true only of transmitters running
25 watts or more. The limit for transmitters running less than 25 watts
is 25uW or -40dB whichever is larger. The Ramsey FX-146 is limited to
25uW spurs by FCC rules. That means the 3.7 watt FX-146 tested by the
ARRL had to meet a -52dBc spec, not a -60dBc spec. My silent key buddy,
Bob, W7FEZ, tuned his FX-146 for 2.5 watts output. We tested it on a
spectrum analyzer before and after the modification. Spurs were at -48dBc
before and -54dBc after. It had to meet a -50dBc spec at a 2.5 watt
output. That's where the earlier -48dB and -50dB figures came from.
I think 10 log(3.7/.000025) is 51.7 dB.

The Ramsey mods are on world.std.com under /pub/hamradio/mods/ramsey.
For those without accounts, ftp.std.com is supposed to work.

Well, "someone" was me.  Sorry about that; it is indeed true that
transmitters between 30 and 225 MHz are limited to -60dBc spurs, except
that transmitters under 25W are limited to -40dBc spurs, never to exceed
25uW.  A 200mW transmitter, for example, can have no spur greater than
20uW.  The "whichever is larger" statment confused me at first; I think
the correct statement is "whichever is smaller", since a -50dBc spur
is smaller than a -40dBc spur.

This is really a policy discussion, and I've set the followups line
to rec.radio.amateur.policy.

  I watched the entire episode from the start on rec.radio.cb. From what

  someone posted a list of 6 MHz frequencies and then you went ballistic
  when Dana joined in the discussion.

I suppose I have to add my voice to the chorus of Heathkit supporters!  I
too have built dozens of their kits from the late 50s on, a few of them
still in use in my shack!

I had a few problems with missing parts and a few defective parts.  The
only "puzzler" I can remember was a piece of glass in a tube on my SB101.
The receiver would work upside down on the bench, but would go dead when I
turned it right side up.  Replacing the tube fixed it - the rig worked
great when I sold it 10 years later!

Heathkit - RIP.
