After teasing everyone with a description of my CQ mobile handbook
circuits,  which will be available if we get permission to reproduce, I
have
good news. I found my other mobile handbook (1960) published by........
that+s right, the A.R.R.L. !! This book also has some neat little
circuits
in it, as well, and we are authorized to share these.

The following is a list of articles I thought would be of most interest
to
the glowbug bunch.  They are mostly simple, low power little rigs. The
transformers for the modulators may be harder to find, especially the
carbon mike-to-grid transformers so frequently used in the day. The RF
portions could be used for cw rigs without the modulator circuits. Tubes
can be substituted, and circuits mixed and matched.  I also threw one
from an old QST.  In the list of articles, I tried to list the tubes
used, their functions, and remarks. There is (gulp) one converter with
a couple of grains of sand in it, but it was intended for use with
hollow
state car BC radios (sweat).

I made a copy of all of these, and am sending them to   Brian Carling
(G3XLQ/AF4K), who kindly volunteered  to scan and post the articles
on his home page.  Thanks, Brian. This may be more than you can handle
on your home page, I don+t know. The articles listed amount to 32 pages.
If we need to eliminate some, maybe we could let the guys email their
vote for the ones they are most interested in. List is as follows:

Hello Jim and the group.

I would love to see those rigs, converters etc.

I will be glad to post the schematics on my web page - AND scan them
if we need that.

The hard part is - HOW do we get in touch with whomever owns the
rights to those old articles now and get their permission?

We got it OK for ARRL things, but CQ is a different story.

Can someone suggest a way to enlighten ourselves about contacting
the publisher?

I may have missed it but I didn't see a response to Jeff's question re
pill bottles plastic and how to remove labels.

Dunno about PETE but HDPE is High Density Polyethylene and its
characteristics
are listed in the Handbook.

Thelabels are a pest. I read recently they come off easier if one smears
them with butter (!). Since we are a lo-cholesterol house I tried olive
oil (virgin, of course) and it seemed to help. There is a certain
variation
in the adhesive used. 

I lifted one edge and ran a bead of oil along and pulled gently. By
keeping 
the oil up, the label came off real neat. However, I never said it
wasn't messy.
A wash with detergent cleans it up, but. Any adhesive that escapes can
be
rubbed off because it is now soft.

The way I remove nasty labels of all kinds is with a product called
Disolve-it. It is orange-oil based, I think.  It works great for removing
label goo, toner ink, old masking tape, etc, etc.  Doesn't seem to harm
paint, either, although I would test it before putting it on my HQ-129X
front panel :-) 

I used to get it at Price/Costco, but since 2 bottles last about a decade, I
haven't looked for it in a while.  Probably any of the Citrus-based cleaners
would work as well, though.

Message-ID: <19970328213219.AAA21104@LOCALNAME>

Hello again BA/GB CW "net" folks,

        Summertime and attendant QRN is coming very quickly.  No doubt the
80 meter
QRG of 3579.5+ will suffice for some nights.  We need to try out and decide
on a 40 meter QRG for the summer and daytime operation.
        7050 has been beset with "Spanish" SSB 'phone stations (an old
problem on 40
since it was a CW only band!) and the digital crowd is creeping down the band.
Unfortunately, it seems a lot of the digital bunch operates with the speaker
turned down or off.
        I would begin to propose we choose some 5 khz multiple, at least at
first.
This would leave 7030, 7035, 7045.  7040 has been the long established QRP
spot for years.  Likewise 7030 is used for the same purpose in Europe.  This
would leave 7035 and 7045.  Does SWBC bother anyone on either of these?
        Comments please.....maybe we can try out some of these during the
Easter weekend?  Say one frequency at 0000Z, another at 0100Z.
        What say ye gentlemen?
73 and ZUT!
