Can anyone provide schematics or point me to a source of circuits for screen
or plate modulators that would be suitable for a Heath AT-1 and/or a Johnson
Navigator? Thx.

Joe - try asking this information in the BOATANCHORS newsgroup or in the
GLOWBUGS mailing list.

I will copy it to both. I bet SOMEONE can help you there!

We have a BUNCH of great home construction articles for old tube radios at:

But it is MOSTLY transmitters.

Why don't all of us BA/GB types go QRP on the QRG of 3579R545 during this
sprint thingie.  It would give the glowbugs a time to shoot for the sky,
too!  Also, it would give me fine Hartley oscillator a chance ``ta shows
wats it be about, again' them thar sandistateishes things wat has lost
their glow and smoke!''  (:+}}.....

All BA/GB stations take note that 0200-0300Z is QRP time on the QRG,
but 0300Z and later is fine for the big boyz on the QRG, OK?  This is
for the period of EACH THURSDAY nite, in February and March, 1997, per below.
I am sure the peanut whistles amongst us (particularly the glowebuggeite
folks, will have a fine rig up fer 5 wattes de ether, byes the bye.....

The ol' ArcusFivus might even give them thar deadbug thingies a run
fer their money!  At 250vdc, it puts out exactly 5 o' them thar ethereal
wattes!

I am sure the glowebuggites amongst the BA/GB crew can give these fellers
a fine set o' logs an' shows them folkes jus' wat real radio be about!
I knows fer a fact that some o' them thar QRP folkes has glowenbottles

Hi gang,

I know this is more of a BA question, but what the heck - they glow, don't 
they?

I just acquired in a trade one each of the following:

        BC 455 B
        BC 454 B
        BC 946 B

I used to have these exact same units as a kid, and fate steered me into
a trade recently for the same three models.  They're the 80m, 40m, and 
VLF versions.

My questions?  

        1. What voltage should I use for the HV?  I know the pinout, but
           not the voltage.  Anyone have a spare power plug?

        2. How selective are these?  Would one make a good tuneable IF
           for a homebrew receiver project?  Or are they too wide?
           How is the sensitivity and stability, as glowbug stuff goes?

        3. Does any one have a spare tuning knob?  None of the three has
           one.

        4. Is the antenna input LO-Z or HI-Z?

        5. Is a schematic available for any of them that anyone knows about?

        6. I don't remember - do they have a BFO? A product detector?

        7.  How many scanning memories are there?  ... just checking to see
            who's sleeping  <g>

Any anecdotes, novice receiver stories, tips, warnings, musings, spells (evil
or otherwise), or other info about these goodies would be neat. I know QST and
the others ran conversion articles with mods and such.  Any of those that
anyone has I'd be happy to pay copying and postage for.  I'd REALLY love to
find a schematic so I could upgrade them with IF filters and the like.

What were they used for?  The only one with a date says March 1945, so I presume
they were WWII service, possibly Korea as well.  But how were they employed?  It
seems odd to have the antenna jack on the front.

Again, sorry if this is too far off topic.  I just feel more friendly with
the 'buggers and I'm not on the BA listserv.  I don't generally post to
newsgroups with this kind of stuff, either, so here I am!

Thanks to all who reply,

Dave WB7AWK

Hi Dave....wow...what a trade!  I've still got three of them myself, but
if you get a notion to sell 'em off...let me know.

Plate voltage is about 220 volts, but remember the filaments are set up
for 24 volts.  You can do a 12 volt tube conversion or wire them all
up for 6 volt operation with the tubes in the list below.

original	replacement
12sk7		6sk7
12k8		6k8
12sr7		6sr7 or 6sq7
12a6		6k6, 6v6 or 6f6
12sf7		6sf7

There is a BFO in place...just a switch on the front panel will enable
that.  

The antenna input is definitly Hi-Z....working into a wire trailed by
the aircraft.

The BC-455 rcvr is about broad as a barn door on 40 meters...but the
LF rig is good for BC band coverage.  The 454 will do fine for 80
meter coverage also.

The IF freqs are:
BC 455 2830 kc
BC 454 1415 kc
BC 946 239 kc
I think I'd offer a guess you might have a trifle of heartache finding
modern filters ready made for those freqs...but who knows?

Good Luck and have fun with those....they are really a chunk of History.
I can still smell the varnish and anti-fungus treatment that reeks out
of those little rigs...think I might even still have a bottle of screws
from them.  It seemed like a million of them when I was a kid.

200 to 250 volts would probably work ok.

Even in '52 we used wires and solder to the plug!

Not very selective (except for the low freq unit perhaps.)

Hmmmmm -- now how did Father Rooney solve *that* one?  I recall
he got a piece of copper tubing, just big enough to fit over
the splined shaft that the knob (if you had it) would go on.
Then he filled the tube with solder, making sure he got good
"wetting" to the tube.  Then he drilled out the tube, to a
dimension slightly smaller than what the spline required.  Then
he tapped the solder-treated copper tube gently over the
spline.  Worked fine, if slightly eccentric (Father Rooney
didn't have a milling machine).  Then he put a normal knob on
the copper tube.

Father never told me.  Just switched my RG-59U from the xmtr to those 
terminals.

There were schematics published at the time ('52) -- I think CQ
was big on mil-surplus conversions.  You are gonna have to be
*lucky* to find one -- but maybe someone on the list ....

Yes they have a BFO -- don't think the product detector was
invented then.

Wow! You want me to write a book?  Guys on this list will *kill* me!
Well I worked Austrailia and New Zealand with it from
Connecticut.  (on 40 meters).  I hated the bandspread -- it
tuned much too fast. There was a mod printed someplace (CQ or
QST) where you put in some fixed "C" and a some trimmers
someplace, and pulled out *all* but one plate of the variable
cap.  I did that one by myself: Thanks for the training, Father
Rooney!  That mod gave very good bandspread, but the
selectivity was never much good -- *you* just got good at
copying thru the qrm.

But how were they employed? 

I believe they were used by pilots -- fighter pilots I believe.
Hope they had better rigs by Korea.

It > seems odd to have the antenna
jack on the front. 

I would bet this had to do with the way the antenna system on a
fighter was hooked up.  Never saw one, never read about how it
worked either.  Check with your local antique pilot's group.
They probably know more about them than anyone nowadays.

The glowbugs would probably be the place for your post.  let's
see what's the list? [email-masked]  

Guess you would do something like: email to
[email-masked]

In Subject put : subscribe
In message put : subscribe    ... or subscribe  your-name   
Just a guess.  If it don't work the robot will probably let you know.

Good to hear from you and good luck.

Hello Dave.
You have found some valuable pieces of history.  Even the 
U.S. Army Signal Corps museam calls them "famous."
I collect, restore to original and operate these type units.
They are part of the WW-II era radio set SCR-274N, and saw
broad service in very many aircraft even up to the 1960s.  
B-17, B-24 and B-29 bombers carried three receivers 
and two transmitters, along with an antenna switch, 
modulator and control boxes.  They were used to talk AM 
plane-to-plane, and were thus known as "command sets."

They were designed to be broad on purpose, because the 
technology of the time did not allow for exact frequency 
setting.  Many planes in your formation of several hundred
might be as much as 5-10 KCs off freq, so broad receivers 
were required.  Here are the freqs of the units you list:

>        BC 455 B  6-9 MC
>        BC 454 B  3-6 MC
>        BC 946 B  550-1500 KC

The LF version is BC-453.  If your "946" tunes 190-500 KC,
then the tags have been switched.  A real 946 in good shape
is rare and valuable.

The units plug into a rack and operate through a control 
box.  The HV is supplied by a dynamotor mounted on the
back deck.  All these parts can still be found, and the 
units can be operated successfully in their historic
configuration.

If you hack, chop "convert" or modify these units, they 
will have no value other then as "parts" hulks 
to collectors and historians.
You can never make a "good," as in "modern operating" 
receiver of them anymore then you can make a Porsche 
sports car out of a Ford model "T" flivver.  All you can
do is destroy an historic relic.  Once you get tired of 
fighting the QRM on 40, it will end up gathering dust
in a box until your hiers throw it in the dumpster.  

It's much better to let a model-T *be* a model T, and 
learn the skill required to drive it on today's roads,  
or pass it on to someone who wishes to do so.

If you wish to use the units in an original configuration,
please contact me in private email for further information.

Subject: Sulking Elephants
Message-ID: <[email-masked]>

Hello, YLs and OMs;

A search on the net for Morse Code yielded -- among other informations --
you as either a CW-Elmer or in some other capacity of supporting CW. That
is why you receive this e-mail. The subject line of this mail is just
abritrarily chosen, and if you look further down on the list for F, you
will find the explanation, what Sulking Elephants and Morse Code have in
common. 

About two weeks ago, I started to query a few newsgroups and mailing lists
for what I initially dubbed "CW Phonetics". Actually, "CW Rhythmics" would
be the more appropriate expression for it. 

In their responses to my query, some guys told me, that no such thing like
"CW Phonetics" does exist. Others contributed real CW-rhythmics or
CW-mnemonics.

Learning Morse Code is gonna be fun, if there are other jewels out there
like the "Telegrapher's Daughter" or the "Sulking Elephants"... Even
though the latter melodic is in Icelandic, the image sticks and so do the
words, along with the dididahdit melody. Some of the character CW melodics
still lack the raffinesse of the Telegrapher's Daughter, and so I am
interested to unearth more CW melodic phrases. 

Do you know of some melodic, that is not in this list? It needs not be in
English, German, Russian or Icelandic. How about some Espanol, Italiano,
Francais ... or whatever your first language might be or had been when you
learnt CW. If funny, it will be enjoyed by some ... 

Many thanks to all who contributed so far - Bolshoi spassibo - Vielen Dank
and I wish I knew the Icelandic for "Thank you"

*************************************************************
Here is an interim report on my query for MORSE CODE MELODICS
Two complete sets of mnemonic words for English, one complete
set for Russian, one complete set for Icelandic (I can't read
it, as some characters show up as graphics symbols instead of
characters on my screen) and one for German were  received in
the last few days, but I have not yet reviewed them nor appen-
ded to this overview.
If you are interested to be informed on how the list develops,
drop me an email and I will update you in sporadic intervals.

I second Dave's opinion, and amplify my own perhaps emotional feelings:

(Soap box mode on.)

If you wish to use the units in an original configuration, I'll give you a
LOT of help and encouragement.

If you want to chop and channel them, I DON'T WANT TO EVER HEAR ABOUT IT!!!
