Jack, I dont know if you have any "Half Price Books" stores where you
are. I have found a 1955 and a 1965 ARRL handbooks for $3.00 each.
Might take a bit of looking to find. Also, I see some on Ebay for sale
sometimes. Good Luck. Randy, WB5KCM

And of course, the subject header didn't say it all, since there are various
reasons someone might be looking for a given year's handbook, but not all
of those reasons actually require the specific year.

Lots of times, people have wanted a specific year, and then it turns out
they wanted a certain project from it, and the project was actually in
multiple years of the handbook, or of course had originally been in QST
(maybe even in a fuller form), and that issue of QST may still be available
in paper form from the ARRL (and if not, they may still supply a photocopy
of a specific article for a fee).

The handbooks change like glaciers, so unless someone is trying to get
a complete set or wants the very same edition as they originally bought,
any specific edition is often bracketted by a few years.

But if I got that year, I would get what I want.

What I am actually looking for is the article or project on using 813's
as triode modulators. If that expands the editions, so be it.

JS, Looking at my 1959 Handbook, there's no project using 813's in a
modulator, per se. The high-power modulator in that issue uses 811A's.
The only project using an 813 is an amplifier, utilizing a single
tube. I'll check deeper in that year and see if I missed something
obvious and/or imbedded in the text on modulation/modulators.

I have a 1964 (11th edition) handbook here, and it has only one transmitter
project which is a little QRP 4-tube set, the Knightkit T-60.

The reference was from an ER article in issue 153-155 by W3BYM. His
email in in qrz so I asked him for more info.

However, seems like QRZ email addys are not much good. Most of them bounce.

I will do some searching, but I think the Radio Handbook, rather than the
Radio Amateur's Handbook, may have the article you are looking for. I know
it has an article on using 813s as triode modulators, which is rather
unusual. And, I am thinking it was further back. Will go upstairs to the
radio book library and do some searching.

The 16th edition Radio Handbook (1962) has a "Zero Bias Tetrode Modulator"
featuring a pair of 813s operating as grounded grid, zerio bias modulators
and claims to have 500 watt output. Page 683

I looked in the 11th edition of Radio Handbook and did not find it, but I am
about 87.22% certain that one of the Handbooks features 813s utilized as
triode modulators.

Will keep looking.

Well, could not find it in the upstairs library. Will need to go out to the
hamshack. If it is not there, I will look in the darkroom. Please say
nothing to my wife about my temporary book displacement.

I can confirm that the 1959 ARRL handbook does NOT have any modulator
using 813s connected as triodes. I have several ARRL handbooks, including
the 1959 edition. One of the guys talked about the Bill Orr "Radio
Handbook". I have only one of the editions, 1956, and it does NOT have any
pair of 813s circuit, triode-connected, for modulators. But, it DOES have
a circuit for triode-connected 807s.

The Thirteenth Edition of the Bill Orr "Radio Handbook" (not the ARRL
handbook) has an article on a 500-watt, 813 modulator with photos,
parts list, and schematic. The next volume I have is the sixteenth
and it only has the schematic and parts list. So, you need something
around the 13th to 16th editions for the 813 modulator article. --Ed

You are absolutely correct and someone has emailed the article to me.

Thanks,

OMG, another two-hobbied person (maybe three with the
books). I paraphrase James Thurber from a parody advice
column:
Q. Doctor, we have books the way some people have mice.
A. I can't tell if you are complaining or bragging.

I brag. My wife complains. Who says you can't have it both ways.

My wife is a librarian. She loves my getting books. She looks for them
for me, lamintates the covers of paperbacks and helps me "weed" the collection.

She's also a ham, so she tolerates my need for radios.
