Heath Mods in QST

[Keith Rowland]

OK, fellow Heath users--here's the first installment of Heath
modification articles that are in the INCOMPLETE collection of QSTs at
my QTH.  There are many more such articles in QSTs I don't have, or
don't have the indexes for, as well as many in past issues of CQ, and
doubtless 73 as well, but I don't have them.

If you are a serious Heath user or collector, you really need to spring
for the 8 bucks or so for the book by Chuck Penson (W7ZZE), "Heathkit, a
Guide to the Amateur Radio Products," published by Electric Radio Press,
Durango, CO.  I think it's available from Electric Radio Magazine, 14643
County Road G, Cortez, CO  81301.

I have no pecuniary interest in Check's book, but his listing of mod
articles, incidental info, product reviews, etc., which are only a part
of his book, go back to the 50s and are gleaned from both QST and CQ.
It's a large book, especially for the low price, done on high quality
paper, and includes excellent photos of all the Heath ham gear, dates
made, description of what each piece does, original price, weight, size,
how rare it is, etc.

It also has a short history of the company, a section on buying and
selling Heath equipment, a master index of all the ham gear by model
number, another index by type--even a time-line section showing when
everything was made in relation to everything else.  Very thorough, a
masterpiece of research, and beautifully done.

FYI:  Chuck advised me recently by e-mail that after he has completed
his move to the southwestern desert, he is considering doing another
book on the Heath test equipment and maybe the other stuff, too.  This
would be great!

OK--with the caveats in place, on to my modest list of mod articles from
QST.  Thisis Part 1.  I will post a few each day until finished, in
order to reduce the load on the server.
