Ask around, John.
I believe that copyrights expire after 17 years.

At least with SONGS they do!

Hi Gary & welcome to the group.
We decided to move the discussions here to GLOWBUGS.

This is a great place to share ideas about building small tube 
transmitters.
Several of us are planning to build these this winter.

Of course, Jeff, that would be a bit dangerous.
I am familiar with those kinds of circuits, typically using tibes 
like a 117N7 or a 117L6

You just have to watch your fingers! - and of course  stay away from the 
chassis at all times!!

Dave - are you considering getting something like that on the air 
again now?

Several of us are going to work on these things this winter & maybe 
even have a net on the air! Or possibly some special activity days.

Scott, if you do it, I would REALLY like to see a copy of that 
schematic, even a hand drawn one!

Did your rig get out a pretty clean signal? Or did it chirp?
That always seems to be more of a challenge with those single stage 
rigs!

See you there!
I hope to get going on this soon.
I don't have much money to spend on this, but I will see what the 
junk box holds!
I have a bunch of tubes here, but I need a HV transformer that will 
give me like 350-0-350 or so for my b+ supply.

You know that MAY be exactly what I will need to use for a chassis 
this winter!

My first project was a power supply for my R-1155 Lancaster Bomber 
WW2 receiver! I built it on a CIRCULAR cake "tin" and it worked 
perfectly!
The hole for the "drop through" transformer, was cut out using an 
electric drill and multiple small holes all in a row!

Harvey - I was at it for years.
When I was in engineering college we actually studied the transfer 
characteristics of tubes.
Everything from mu to gain, various parameters.
As a kidgrowing up in England.  I had built working transmitters even from long 
before I had a  license.
You were required to be 16 years old to get a ticket and there was no 
novice or tech license, and NO multiple guess test!

More details later...

No no no! That won't work, Bry. You send a message to:
[email-masked] and only write:
subscribe glowbugs <your name/call>   (without the "<>").

You see, ThePorch.com hosts at least three lists, and ListProc always
uses the format:
subscribe <list name> <your name>
Lehigh.edu uses ListProc for the QRP-L list; same procedure. 

Keep the soldering iron hot and the fingers cool,

Subject: QRP articles of interest from 50s/60s
Message-ID: <[email-masked]>

Hello all,  I'm a new subscriber here (like many) but long time subscriber of
both QRP-L and Boatanchors.  I guess you could say I caught the "bug".

All this talk about QRP with tubes got me curious about magazine articles from
the 50s and 60s that this group might be interested in.  I pulled out my stack
of old mags and sifted through the "noise" and found the following articles
that may spark interest with some here:

QST, March, 1956,   Page 11   "CQ TR" 
        Describes one of the first transistor QRP rigs.  Power input:  55mW
        Very compact...  way before it's time.  (I know it ain't hollow state,
        but thought it would be of interest.)

QST, June, 1956,    Page 34   "The Novice Special"
        Simple two tube Receiver with "Good sock".  Uses two 6AQ5s (Detector and
        Audio Amp).  Tuned input, not xtal controlled, but could be adapted.
        Power supply: 250VDC @ 50mA and 6.3VAC, uses 5Y3GT.

QST, July, 1956,    Page 15   "Twenty Five Watts for the Beginner"
        One tube (6DQ6A) 80 meter crystal controlled transmitter.
        Power supply: 325VDC @ 125mA and 6.3VAC, uses 5Y3GT.

QST, October, 1956, Page 22   "A Single Tube Converter for the Novice Special"
        Single tube (6AN8) converter for the Novice Special receiver to help
        high frequency (above 7 MHz) stability.  Uses crystal oscillator
section.
        Power supply: Existing Novice Special supply.

QST, December, 1958, Page 24  "Two Tube Mobile Transmitter"
        Two tube (12AT7 and 6CL6) 10 watt input AM transmitter (could be
modified
        for CW).  One half of the 12AT7 is Modulator, other half is Oscillator.
        Power supply: Requires 200 to 300 VDC @ 90mA, 6 or 12 V for filaments.
        Crystal controlled.

73, March, 1963,    Page 22   "QRP Transmitter"
        Simple one tube crystal controlled transmitter.  Uses a 1S4 tube
($1.50 at
        AES). "Can be loaded up to 1/2 watt with 90 volts B+".  Not sure if this
        means 1/2 watt input or output.  Definitly qualifies as peanut whistle.
        Power supply: Requires 90 VDC and 1.5V for filament.
        (Special note:  this was 73 Mag's famous "Receiver Issue")

QST, February, 1964, Page 20  "Some Notes on Reducing Power"
        An interesting article outlining various methodes for reducing
output power
        in tube gear.  Covers plate voltage, screen voltage and "brute force" 
        (attenutating output) methods.

I'm sure there are alot more articles available.  These were taken from my
limited
stock of "classic age" ham mags.  If anyone as other article leads, please pass
them on.

Personal Introduction:
I collect "classic" crystal controlled CW Novice rigs from the 50s and 60s.
These 
"mini-BAs" exist in that strange space between QRP and QRO (10 to 45 watts
output).
The advantage to these little critters is they are relatively cheap; easy to
work
on; LIGHT WEIGHT; and use standard, time tested, easy to troubleshoot circuitry.
I especially love to find old rigs that have yet to have their first QSO.  These
hard to find gems were typically built by a young novice back in the 50s/60s
without an elmer's help.  Construction techniques are usually pretty poor,
so poor
that the rig never operated in the first place.  I intentionally try to leave as
much of the original workmanship (or lack there of) intact out of respect
for the
little tike that built it way back when, then, put it on the air for it's first
QSO.  About the only thing I get a kick out of more is being the first CW
QSO for
a brand new licensee.  One fantasy I have is to find one of these
inoperative rigs, restore it, find the original owner (now much older) and
return it to them for use.
Oh well, one can always dream.
Anyway, that's me.. among other things.

I have also found Mouser to be very friendly to small quantity purchasers and
don't seem to resent handling lotsa one and two thingy orders. They even carry
xtal earplugs. Speaking of crystals, any of you guys members of the Xtal Set Society?
Anybody interested in occasional chats about xtal set construction, experiences, etc?

Well....., ahhh....., er..... lets me twiddles de ol' glowbottle time

p.s.  If any o' the glowbugge folks were on the Classic eXchange run
      last night, I would appreciate feeadback of anyone that heard
      ol' Grandma Hartley burning holes in the ether last night.
      I stoked her fires most highly to get her to squeek 2 bottlewatts
      through the ether, and managed to make a few qso's as far north
      as the Big Apple and as far west as ChiTown.  But it was hard to
      compete with the Viking 500 crowd.....(:+\\.....

Well, thar me friend, plys ye the ether wid that fine ol' 7050 rock, an
joins us in the evenings on the BA/GB Friendly Firebottle Fist Function
roundtable:

   QTR 0100Z QRG 7050R500KHZ
   QTR 0200Z QRG 3579R545KHZ (rips ye up an olden tv fer its colorburst rock)
   QTR 0300Z QRG 1802R500KHZ
   QTR 0400Z QRG 3579R545KHZ (mostly fer OT pre-ww2 bottleburners).

Also, grapples ye up a televiseocolorburstorocco fer a fine gang o' folks.
Most of us are on the left bank, but when conditions be good, the right bank
also can be heard.
