To any and all in net land. I got a Heathkit IM 16 solid state
volt/ohm/milliamp meter at a hamfest for a buck.. It is some what
chopped up. If any body has a schematic and specs on this beast
please send them to me... I will pay for postage and copying as
necessary.
Tnx, Clark Fishman WA2UNN

Subject: Alternators
I have a problem not at all related to ham radio but I've noticed
some comments on vehicle alternators recently and though I'd
ask. I have a 82 VW Rabbit, diesel variety. The alternator light is
on. The alternator is good, bench tested it at an alternator shop.
The alternator has a built in regulator. I have checked the wire that
goes the alternator that supplies voltage to start the field, and the
voltage is about 2 volts. I have some problems with the wiring near
the fuse box and at this point I don't wish to deal with this
mess (this is a back up to my "winter" car and for $500 I couldn't
go wrong). My question is can I run a switched, fused wire from the battery
directly to the "field coil" connection on the alternator?
Thanks for your help!

Subject: Info wanted: IC-275
I'd like to find out some info about the Icom IC-275:
What ways can a computer control the operation of this radio? What data
rate would it connect at? Does connecting a computer to control the radio
exclude yet another connection for packet operation (the data to sent and
receive)?
Can it be modified for out of band? Have you actually seen the modifications?

Subject: Locking coil slugs.
If you've rebuilt some gear and realigned it, rather than locking the tuning
slugs with wax (which will harden and make you likely to crack the slugs
next time you realign it), try and get hold of a piece of elastic. If you
tease the fibres out, you will end up with some very fine threads of rubber.
If you hang one of these into the core before putting the slug in (dissolve
off any remaining wax first) then screw in the slug, you will find it holds the
slug beautifully. In five years, when you next need to realign the rig, the
rubber thread will have perished, but its remains still hold the core. When
you turn the slug, the rubber breaks into tiny pieces and allows you to unwind
the slug. Put in a new rubber thread, and off you go. I have *NEVER* had
a slug crack if it has been retained in this way.
p.s. if you have seized slugs, try soaking them in some organic solvent
(Trichlorethylene, carbon tetrachloride) for a while to soften the
wax - but be careful - the coil former may turn into a gooey lump
of melted plastic!
If your rig has areas of the PCB coated with wax, be careful - its often
the PLL coils/components that are so treated. If you melt off the wax, then
the inter-component capacitances will all change, and you may end up having
to realign the PLL.

Subject: new Part 97
If the event that needs radio coordination is non-profit, what you might do is
approach a local "rent-a-radio" place about loaning radio equipment (and the
cooresponding frequency and repeater support if necessary) and let the hams
volunteer as the radio operators and coordination support. That will get
you operating within the business radio service so everything will be legal
by the FCC.
Non-profit organizations don't always get everything free, remember, and they
technically have to buy things like any other organziation. They just the
tax advantage of attracting donations. But, they don't any rights to make
use of the Amateur Radio spectrum for doing these things.
Amateur can and should be used for true emergency communications. It's OK
to be all set up and prepared for an emergency, and of course we all know
that we usually communicate lots of idle chit-chat just to make sure that
the radios are in good working order all the time.

ARE YOU SURE?!? The adapters are for the smaller RG-58/U ONLY!
PL-259's are meant to handle RG/8 or RG/11 DIRECTLY!

TUVA was Dr. Richard Feinman's favourite place.

I contacted a station on 15M last night (10pm ET) from the TUVA soviet republic.
It was RA0/UA9YX on 21295 kHz.
This is the first time I've heard this area of the Soviet Union on Ham Radio.
Perhaps others may be interested. (B T W Tuva is the geographical centre of
Asia)
There was a very funny show on PBS (I think it was Nova) about Richard
Feynmann of the Feynmann Lectures on Physics. He decided to try to visit
Tuva, because as far as he could tell no Westerner had ever been there.
Unfortunately, in the pre-glasnost era, that proved impossible.
