Is the Broadcast Transmitter Mafia circling Farmville yet?  ;D

Seriously, thanks for that Paul, very interesting.  Wonder how many re-tubes it's gone thru in its life?

YES It is still in use !!!
I just spoke with the front office.
Woman answers, says "Oh, yes, Big Bertha still going strong !"


There's also a bit more on the reflector too --

>>If you simply want to predate 1965, find a Gates BC-1T. Hundreds if
not
thousands of those were built in about 1960-65 as Class IV's were
allowed
to increase day power from 250 W to 1 kW. This was before they were
permitted 1 kW night operation, and the BC-1T had a 1kW/250 manual
switch
as standard equipment.

There is a BC-1T in Vienna Georgia.  Don't know if it works or not, in
the
middle of hooking it up, the station was sold and the new owners didn't
want
me to finish the job.  They insisted on relying on the MW-1A.

How about the oldest COMMERCIAL/Broadcast Transmitter still on the air in AMATEUR usage in North America? That should be even more interesting.
Da Rules:
Must be hooked up and on the air--not in the barn--you will be required to prove it!
must use the original type finals --or equivalent if the oldies are unobtainium
No gutted cabinets with modern innards--must be at least resemble the original--
band conversions are obviously OK
No Military--that is a different category
any entries? ???

Skip/YOO, the final judge in this matter,  has been out here and on the air with it.

How about the oldest CB in daily use?

Johnson Messenger 1 ?.... Courier 1M ?  Ratheon "Ray-Tel"?  ;D ;D ;D

There should be still be something older.  How about pre-WW2?  Even if it is just a stand-by.  The BC1-T is a real johnny-come-lately as far as transmitters go.  Anything homebrew (the broadcast term is a "composite" transmitter)?

My homebrew HF-300 rig uses the outer shell of a 1936-era 250w broadcast transmitter, but it had been gutted when I got it.  The transmitter does use  a lot of the original broadcast parts, and most of the stuff now in it is from the same era, plus the original dials, meters, control knobs and nameplates.

The original composite trasmitter used a single HD-203A to drive 3 regular 203-A's in parallel, modulated by a pair of 838's.  It was built in the mid-30's and used until the late 50's when they replaced it with a BC1-T.  A ended up getting that BC1-T a couple of years ago too, purely by coincidence.

WRIB in Providence, RI. signed on in 1946 with a Raytheon RA-250, serial #166.  Now in almost daily use here in Celina, OH. on 160M.

813 driving a pair of 810's, modulated by a pair of 810's, connected to a 2 wave lenght loop for 160M.

Yeah, you and Jay both have me beat with those rigs turning 60 next month.

His modified RA-250 is on 160 after a few years up on 75m.

And Don, you're right, WB8SKV used to run a pre-war Western Electric like Joe IBX now has, but not on the air yet.  I think Larry later turned slopbucket and changed his call.

KK4BO ran a 30's vintage Western Electric TX on 160 meters back in the 90's. Haven't heard it or him on in years.

Paul - Interesting fact about the BC1-T. Around December 1961, the small town where I live, Washington Crossing, Pa became host to it's first transmitting site from station WAAM. It's transmitter was a Gates BC1-T. It just so happens that the station was sold many times to many owners and the SAME BC1-T made appearances at many stations throughout New Jersey and eventually wound up in my basement shack!

Steve,
        If you'll use it I can give you one of those little single channel crapstal corntrolled Johnson Messenger "cube" jobs from 1959, caw mawn.

Steve said:
Lamont, KK4BO had that WE grid modulated rig with the six 211's in it. He eventually sold it to Larry WB8SKV who claimed to have a devil of a time keying it on 160. Joe, N3IBX has one of these waiting in the proverbial transmitter que. Lamont last I heard had returned to Goochland Co. in VA and he and his wife are co-owners/managers of a station around the Richmond area.

I believe Al Weiner is using a Western Electric 12A circa 1932 in some capacity at his AM station WREM up in Monticello on 710 KHZ.  This is a daytimer with some low power authorization at night for which I think he's using the 12A or is planning to.  73 Doug. K2JJ

Hey Joe!

You actually remember your CB call letters?..good memory!... Honestly, I hold some of those old CB rigs near and dear.. Johnson, Tram, Browning, Courier and of course Lafayette...

I remember when the rules stated 10 mins on / 10 mins off.. and no hobby type communications! Very strict!  :o

How did the 11M thread get in here?
Anyway VJB and KYV are on the right track--but It looks like IBX could be on top of the heap (or buried under it) if he would quit inhaling rigs and put the WE on the air.
The gauntlet is down Joe!!!!!

Doug - I believe the 12A that Alan has is rated at 100 watts which would be perfect for his low power requirement. I was talking to Timmy, WA1 HnryYellar about it on the air not too long ago. If Alan does this I'm just about positive that he'll have the oldest broadcast transmitter in "active" service in the Northern Hemisphere. That would be "kewlbeanerz"!

I believe the 12A isn't a whole lot different from the WE 451A series except for a few cosmetics and power output (100W vs 250W). It's a grid modulated job with a perforated front panel to keep an eye on the tubes.

Regards,
          Joe Cro N3IBX

Glen - My favorite was the Tram D201A with the built in "slider" VFO. The audio quality with a crapstal headded D-Ten-Four was tremendous. Lots of bottom end.

Yo Skip - I resemble that remark! Transmitters are like Jello - There's always room for more - hi!

Actually I have to get a hold of  a big shoehorn to fit a few items in the basement shack, the Western Electric 451A-1, a newly acquired Collins "TDO" (813's X 805's), a big Western Electric Maritime transmitter, a 4CX1000 "leenyar" and a few other pieces in the garage are awaiting deployment into the basement shack. Plenty of muscle will be needed!

The major holdup is manpower and time, etc. Eventually I'll get to it. I really want to hear the WE broadcash box sing for it's supper on 160 Meters, and can't wait to see the glow of the sextet of WE 242C's through the window.

Hope to catch you on 75M soon.

Best Regards,

The bigger it is and more it weighs, the better it will work!

Talk about a nightmare revisited  . . .   when I was in high school my electronics shop teacher was W2IJE (sk.)  He had this idea for raising money for the ham club.  We started taking in CBs in need of repair and did the work for $10 plus parts.  This being the late 70s, we were regularly swamped with work.

One teacher had one of those Johnson Messengers and the receiver was out.  I drew that straw.  I did the signal trace from start to finish.  Every stage in that thing worked correctly.  The coupling between each stage was fine.  But the thing wouldn't receive. 

After a couple weeks of this IJE went over it himself with negative results.  We never did figure out what was wrong with it.  Gremlins or something, who knows.   

Flashbacks . . .   thanks Joe.

Just so we all know what we're talking about, its the White Face Johnson, as I remember it, shown below. Highly prized even in the late 60s wnen it was new, since the tube final could be tweaked to 15 or 20 watts or so.

huh-HA !!!

Paul,
      I'ze got the white faced Johnson "Messenger" (it's all tubes on the inside on both). I've been thinking about converting it to 10 Meters. It even has the original slim Johnson chromium microphonium attached w/o a connector directly into the set. I believe it was originally advertised as being a 10 Meter tranceiver that could go on 11 Mters by just adding the appropriate crapstals and tweaking it. I believe it's currently setup on channel 9.

Speaking of Junkston CB's, Do you remember the special gold plated 23 Channel "Anniversary" Messenger base station? It even came with a gold plate Turner +3/Johnson microphonium. I still have it after all these years. I just couldn't bring myself to swap it or get rid of it. Ditto on a B&K "Cobra" 23 channel base job, a Lafayette "Comstat 25B" with a "range boost" circut. The range boost circut guaranteed you'd strap anybody - hi!

Ashtabula Bill,W8VYZ has a modified "Range Boost" strap circut in his 803 rig - hi! With a "Range Boost" you'll not only strap slopbuckets; but other AM stations as well.

This is the "Green Hornet", KBTX6603 come awn......

Skip, K7YOO,
                 This thread went from broadcast transmitters to CB's. Funny how things work out; them both being at opposite sides of the spectrum.

Regards,
            Joe N3IBX

Yep, it was indeed the whiteface that caused my nightmares for a long time.

If I had one now . . . 10AM might be a good idea.  Hmmm . . .

SALMON REIGNITES BLACK BOND SPECULATION

British actor COLIN SALMON has reignited speculation he is to play the first black JAMES BOND, after confessing he has been in secret talks with producers of the superspy movies.

Tipped by PIERCE BROSNAN last year (04) as a good successor to the 007 role, Salmon has already starred in three Bond films as MI6 Chief of Staff, CHARLES ROBINSON.

And the respected RESIDENT EVIL actor admits that this, rather than racial prejudice, could cost him the lead role.

He says, "If I don't get the part, I won't think it's because I'm black. The producers have proved they can make brave appointments by casting Pierce Brosnan.

"If you'd said in the Seventies there would be an Irish Bond, people would have thought it was a joke.

"The process is more political than politics but I really want to be Bond. I know the British public is behind me."

You guys are frickin killing me....  ;D ;D ;D ;D

You've convinced me to add "Range Boast" to all of my rigs.... thanks for the hot tip.

EVERYBODY!!  ON THE FLOOR!   I'M HIJACKING THIS THREAD TO CUBA!

Johnnie,
           I wonder what old broadcast boxes one might unearth in Cuba? Think of the possibilities! The only problem would be logistics; and the fact that they probably still run them everyday.

I wonder if any Cuban stations still run the elusive Western Electric 1A? What a beautiful box! It's a Heising modulated Hartley oscillator circa 1922 with big beautiful meters etc on it. I NEED one for my basement shack and would move it up to the top of the que to be worked on.

Hola 360 Meters!

Hey Joe;

Although I've never had the pleasure of visiting the vortex, From the photo's I've seen, and after talking to Ken W2DTC, I can't imagine how you could possibly fit another VF1 in there let alone another broadcash transmitter!!  :o

Your shack should be on the Sci-Fi channel... defying the laws of physics!  ;D ;D

Mark - Good point! My Western Electric 451A-1 was originally rescued from a "Bible Beater" station in Mexico over 20 years ago.

Glen,
      You are welcome anytime!

He's a friendly guy you can calll "Dick"! When you "STRAPPED" that comment over the air it was perfect timing!

Paul - I think you just (appropriately) named my WE 451A-1. "Major Wood" is what one will get seeing the SEXtet of WE 242C's lit off! From now on that's what I'll call him.

 
Joe, I think you suffer from RF induced priapism.

No comment, but I tell all the young girls I can lick my eyebrows!

Just make sure you don't have a hellhound on your tail!

I went down there, but nobody knows you when you're down and out. So instead I went to sweet home Chicago. Don't you want to go?

Steve,
        Would there be a Western Electric 1A awaiting being saved?

It is amazing how a topic can unravel and become "threads"
You lost me at the CB radios and sheep. A real baaaad 10-4


My interest revived a bit with the south of the border transmitter hunt. I know of some good places to start. I have been in several flea markets in Bogota, Lima, and other strange places. I also know of some hole in the wall radio repair shops that have big mod iron on the shelves--upon inquiry the proprietors knew where to get more--from the "cajas grandes gris". It is like panning for gold--follow the flakes to the mother lode---speaking of flakes.....

I'd bet there are some nice pre WW2 transmitters hidden away down there, dating all the way back to the 20's.  There used to be many low power shortwave broadcast stations on the air in Mexico.  You could hear them in the 25m shortwave band during the day.  They apparently have all gone dark now.  No doubt a lot of low power MW BC transmitters that are no longer in use, too.  And they don't have the same engrained throw-it-away mentality as the Gringos, so no telling what might be stashed away in some old shed somewhere.
