About two years ago, (pre N.Y. Times arcticle) I had found an old
Heathkit Shortwave Receiver at a hamfest for five bucks.  Tubes checked
out ok and it squeaked and crackled some, so I wanted to check alingment;
I called local Heath\Zenith store and they gave me an 800 number I have since
lost (try 1-800-555-1212) and I chatted with a very nice person where upon I
found that Heath manuals (copies) are (were) available directly from Heath!
They leave out the "Strip 1/4" from the 6" red wire..." stuff when they
copy the manual and there was a max charge of like eight bucks or something
- far less than HI-Manuals gets for his stuff.  I'd try thay route before
springing bucks to Council Bluffs.  If all else fails he may be the only
source - but he is pricey (but fast).  I have bought eight or ten manuals from
him.  Glad he's there - .  73 and DX de KA2Y k

Bert, about the only thing that you can do, other than giving the batteries
an hour or two of charge once every few weeks, is to fully charge the
batteries, remove them from the H/T, and place 'em in the freezer section
of your refrigerator.  This will slow down the self-discharge rate of
the cells.  The self-discharge won't be completely stopped, since the
potassium hydroxide electrolyte won't freeze at the temperature of the
average freezer.

You might want to review my article on NiCad batteries in the Feb issue
of QST.

Sounds like a fascinating chip. Jeff Duntemann (KG7JF) and I (but mostly
he) have been working on the idea of easy-to-build VHF receivers and
transmitters.  We contend that with modern printed circuit boards and
ICs, it's probably easier to build a 2-meter FM rig today than it was
to build a CW HF rig in 1940.

I have an old IC-2AT which I use VERY infrequently, but when I need to use it
I want it to work. I just took it out of 'storage' and found that both 
battery packs were dead and wouldn't hold a charge anymore. I've replaced 
the inards of the packs.
What's the best way to store the batteries so that they'll at least be

    In many cases the IRC gets used as currency and never redeemed for a stamp.

    If you get an IRC with an incoming card, you can buy the return stamp with
your local currency, saving the IRC for when you initiate a QSL exchange. This
neatly avoids their poor financial efficiency. Some people with a surplus sell
them off at prices between cost and redemption value.




   It always seems unacceptable to me that one station of two in contact should
be EXPECTED to pay for both cards and both postage. When confronted with "send
$2/whatever  for my card" I make a point of relying that my card costs $XXX
and that I only QSL on receipt.

   I always QSL, at my own cost, if the other station requests a QSL. Direct.
but I will not pay the other station's QSL costs. If he wants to send me a card
I'll be happy. I just consider the radio bit to be more important than the
postal bit. Be insulted if I ever ask you for a QSL, it will be because I 
want confirmation because of suspected piracy !  

  Not wanting to sound mean, but maybe this thing is getting out of hand.

Definitely, since the CuO rectifier was used in the original Vu meter standard
which dates back well before WW2.  I also know that commercial selenium
rectifiers date back from the late nineteenth century, although of course
they weren't much good as detectors.

Clark, there are dozens and dozens of varieties of ferrite (called "mixes").
These are developed for different frequency ranges, different quality
factors ("Q"), and also different permeabilities.  This means that even
if you can find a slug that will mechanically fit into your coil form,
the chances of this slug matching the characteristics of the broken
one are about a thousand to one.

I'd try the Kenwood approach first and get an entire replacement coil.
If Kenwood, for wome reason, doesn't have a stock replacement, try the
local Ham dealers/repair facilities.  You can usually find a dealer
who has a replacement coil he would be willing to part with.  This way,
you know that the rig's performance will not be degraded.  Also, I would
suspect that the threaded interior of the coil form will be damaged
by any attempt to remove the broken slug.

Good luck.

I don't know if it's possible to make the 470 transmit in the 220-240
area, but from looking at the schematic of mine, I'll venture that
it's impossible to do so and radiate a clean signal. There is no
filter to keep second harmonics of 220-240 from the antenna. If you
show up on 450-480, especially a police repeater, you'll be hearing
about it. If the PA will work at all on the 220-240 range, it's not
likely to be matched at all well and may self-destruct.

Ditto.  As a near-penniless high school student, I was able to get on
the air because of the DX-60 I put together from a kit.  I never had
a moment's trouble with it.

When I got my General ticket, I bought a DX-100 (used), and likewise
had a decent AM signal for low bucks.

Fast forward to 1991.  I miss the broadcast quality of AM and decide I
have to have an AM rig again.  What did I look for?  Right.   A Heath
DX-100.  35 years old and heavy as an anvil, it works flawlessly.

Amen.  Not expert enough to design homebrew stuff at the time, and not

had it not been for Heathkits.

Ramsey--and the 2 meter transceiver:

I had previously posted a series of notes about problems
that I have experienced with my 2 meter kit being off
frequency and problems tuning it up.

I had called and a technician had told me that they had
problems with a batch of crystals..

I just received a call from John Ramsey.  He took the time to
very nicely explain to me that the rig being off frequency
is due to different lead lenghts and different builders
putting the kit together with different lead lenths and
solder etc.

He also explained the way to put the capacitors in the
circuit to correct the problem and how to tune the rig to
get full power (I am only getting out about 2 watts) they
have you wind the coils too tight so that you can stretch
them out when tuning...

Again I am new at this electronics information (just taking
an intro course now..just got to inductance) and think I
finally understand what is going on..

I appreciated the fact that they were concerned about my
letter and having satisfied customers. Too often when you
register a complaint they ignore you or get nasty.

 Time for another Ten-Tec plug...  The Paragon, thankfully, does not have
 any custom silicon in it.  Ten-Tec opted to go the generic uP with "detached"
 eprom route.  In fact, they have already given me one free software upgrade
 during the warranty period, and I have no doubt that they will provide that
 service into the future.  Granted, the uP and ram chips are getting dated,
 but they are made by Motorola and are soooo easy to find.  I'm collecting
 spares right now...  Even the fluorescent display is relatively generic,
 having no special symbols or anything.  There are no nasty surface mount
 components, which partly explains why the radio is big enough to have
 "real" knobs that a "real" American male hand can grip.  I could have bought
 a TS-850 and had newer technology without question.  The Paragon really did 
 what I needed, so I spent my $1800 on maintainability.  Oh yes, they give
 you the service manual with the radio purchase.

      Wonderful rhetoric, but the United States of America isn't a private
club.  If you think about it, perhaps you'd agree that our Nation gives a
group like the ARRL the right to disagree with a certain 'lifestyle,' much
like the ARRL would probably not allow advertisements for the KKK Radio Klub
to be published.   If you don't like the ARRL's policy, don't rejoin, or do
something constructive to attempt to change that policy.

I have a commercial 440 ht.  It seems durable enough.  If you want to 
access a new repeater, or travel with it, then you have to order some
new rocks and choose which of the old channels you are going to displace.

Oh, you want one with a synthesizer?  Now you are back to features.
If it is a commercial unit, the channels will probably have to be
programmed from a PC, because direct keyin doesn't mix will with

Yes, it would be nice to have the best of both worlds.
