Subject: The 40 meter "shift" again
Hello Gang,
Someone on another reflector came up with a Brilliant idea IF this
6.9-7.2 Mhz 'relocation' comes down for 40 meters.
It's super simple: Allocate the new 6.9 to 7.0 mhz slice exactly as the
7.2-7.3 Mhz segment is allocated. This will preserve the CW sub-band
where it is now to allow QRP and BA gear users to still operate their
equipment without extensive modification or change. At the same time,
the "AM" users can lay claim to the 6990 and 6995 spots for AM voice
operation in the shifted sub-band. Most of the old rigs will go there with
no modification, as there is 5-10 khz of "leeway" on the low end of
most VFO calibrations.
If you like the idea, let's talk it up now with other hams and the
ARRL bunch. It's not too early to do this. The more support we can
get, the longer we can use our beloved "boat anchor" rigs!

Subject: Re: Old Tubes - Help!
Hi, Rod,
As a matter of fact, I do know where you can get a socket. Antique
Electronic Supply has two sockets that will take a 211/VT-4C. The 1st is
part # P-ST4-192, at $6.50 ea. The 2nd is part @ P-ST4-193, at $15.95.
The latter one has gold-plated contacts.
If you're lucky enough to find a socket at a hamfest, the going rate
ranges from $2 - $5. Both the AES sockes are made in China. The only
caveat is that if they're temporarily out of stock, you may have to wait
a while. That's what happened to me when I bought a couple a few year's
back. At the time I did, they weren't offering the gold-plated variety,
but it's a fine, sturdy socket with a white ceramic base. I'd go for the
$6.50 model - something tells me the gold-plated one is catering to the
golden-ear crowd. The phone# for Antique Electronic Supply is (602)
820-5411. (I have no connection to the business other than being a
satified customer - Gawd, I WISH I could make a living doing something
related to this stuff!). The filament of the 211 requires 10V @ 3.25A.
One of the projects on my Round Tuit list is a 203A -> 211 MOPA rig,
series-modulated with a class A 833A. Pretty much have everything I need
but the time! (Come to think of it, I could use a "socket" for an 833A,
if you can call it that. I was planning on fabricating one 'cause they're
rather scarce, but the real McCoy would be much nicer! Too bad AES
doesn't carry those! But I digress...)
Good luck, and hope to hear that 211 Hartley rig a-perkolatin' soon!

Subject: Re: 39/44 tube.
Claton,
The 39/44 is a remote-cutoff pentode used in RF/IF amp stages in
receivers, particularly those employing AVC. (I'm paraphrasing the ole'
RCA tube manual here, can ya' tell?) The heater wants 6.3V @ 0.3A, and
the suppressor grid is connected to the cathode internally. Might make a
good regenerative detector, as the detector in the famous RAL uses a 6D6,
also a remote-cutoff pentode. The RAL obtains its feedback via a tickler
in the cathode cicuit, so having the suppressor connected to the cathode
may require grounding the cathode/supressor and connecting the tickler in
the plate circuit instead (which is a much more common hookup, anyway).
If you try it, let us know how it works.
As far as transmitter use goes, the tube might be useful as a cystal osc.
or VFO in a multistage design, but as a single-stage rig you're looking
at peanut power fer sure....
As far as it's worth, AES lists NOS 39/44's for $3.00 in their latest
catalog. So either there's not much demand, or there's a ton of them
around. I wouldn't mind getting my hands on a few, though... could be fun
to play with, and at $3.00 a pop, the price is right!

Great! I had others like 805's laying around, so I never pursued the
added cap idea. But, your neato little trick gimick is a great use of
PC board! Kudos!

Paralle two on each side. More Power!

This is all well and good and sounds like a real blast....BUT....do we
need "Divisions" or something? I have tried for the past several months
to work east of Ole Miss and haven't had a heck of a lot of luck, and this
was on 3579. I shudder to think what might happen on top band.
Although I am trying, manfully, to get some of the local old timers
interested in this type of endevour, so far my efforts are only beginning
to arouse interest. Most think I am nuts.
About the only GB'ers I have worked are Adam McLoughlan '6POC on 40, Ken
KD6B with his ART-13 on 80, and Jack W7QQQ on 40 with his one tube 35
watter with its pretty signal.
Although Brian WA5UEC in Plano, Texas has heard me twice on 3579, he had a
difficult time.
Ideas, anyone? I suppose if you guys in the east want to have your own
"contest" you can go ahead, but it seems sort of .... well, YOU know.

I am game.
Also, lets try to keep the 3579 and 1802 alive until 0600Z and later,
particularly 0500Z-0600Z for the WestCoasters to chime in on.
I will try to keep something lit 0500-0700Z each nite over the next
week on 3579, to see if you can be heard back east.

I did hear Sandy last night, about the time you called him. I ***THINK***
I heard you in there, but with my 75-90 watts I don't think you are going
to hear me. Will try again tonight.

Ken; Your/my SASE flew the coop today. What is Jack W7QQQ
floorboarding to run his Hartly down the road at 35 Watts? Any

Great! I mailed three out today, Jack's, Walt's, and another I can't
remember, so as soon as yours gets here, out it goes.

Its not a Hartley: it is a crystal controlled one tuber with the prettiest
tone I have ever heard. Absolutely beautiful!

Ask Jack. I dunno what he is using, but you can bet, from the keying, he
modified that dude a little: at least in the keying department.

Been watching. I am really anxious to hear one of these rigs (811A/813)
on the air.
Heard W5TVW again tonight, and W7ZFB. Called ZFB several times. Even
followed his excursions up and down the band, but no luck. Also heard
W5ZR pretty loud while in QSO with ZFB. Neither heard me. This all about
0300 - 0350 or so. W5ZR started out really strong and then faded clear out
within about 20 minutes. Band is kinda funny. Maybe I need to build a
full-sized 5 element rotatable yagi for 80.

Heard Sandy W5TVW calling WB7ZFR at 0440. Sandy was about 56/79. Nice and
clear. He didn't hear me.
Heard Bob NZ4G working someone at 0545. Bob was about 449, but he sure
sounded nice. He didn't hear me either. The guy he was working was about
500 cycles lower and right in the TV QRM.
Mayhap conditions are getting better?????
