OK...How About Rare and Uncommon Transmitters?

[W9GT]

Here is an very unusual one for you.  1947 vintage John Meck T-60-1.  Pair of 6L6s plate modulated by a pair of 6L6s.  I have this one on the air.  Any others out there?

The KLUGE California Kilowatt ?

The AN/URT-12 (ser. # 40). I know of only three still existing. Two of them are owned by Sam KF4TXQ. Maybe a 4th in a Coast Guard museum ship but unverified. 100W CW/90W carrier, par. 4-65 mod by pp 4-65.

Eldico SSB-100M mobile AM, CW, SSB transmitter.

Palco Bantam 65 mobile AM/CW transmitter.

Moore's book on Transmitters 1930-1980 details many transmitters, many of which could be considered rare and uncommon.

You need to look no further than N3IBX's basement. If it was ever manufactured, he has at least one or two of them! !

Indeed! Also included is 'home-brew'!

what about that TMC 750 thing that there are only around three of?  W3JN has one  I think.   The one with the AM modulator deck option.

You mean TMC GPT-750?

Subraco MT-15X   I have one of these little jobs...not working yet, but should be easy to get it going.  2E26 plate mod by class B 1635 (similar to 6N7).

I think there were more than three GPT750s around.  I recall hearing quite a few of them in the 70's.  One model has a factory modulator, which uses a pair of 810's.  The other is minus the modulator deck.

I remember a fellow who had one on 75m AM in RI in the mid 70's.  Can't recall his name or callsign now.  It put out a good signal, but the audio was strictly space shuttle quality.  I'm sure that  could have been corrected with a little work on the speech amp. I believe I recall seeing ads for them in the mid to late 50's ARRL handbooks, along with the matching receiver which strongly resembled a Hammarlund, at least appearance wise.

[W9GT]

Not sure of the type of modulation, but they had a voice multiplex unit available for the GPT-750 that would provide 4 voice channels.  They were used commercially for telephone circuits in the Caribbean.  A ham friend that I worked with at GTE had a GPT-750, so equipped, that was scrapped in the 80's.  He acquired it while working for the phone co in The Dominican Republic.

When alive, Gary/W7FG had 3 GPT 750s, one had the AM mod deck and another the SSB deck.  The third did not have anything.  I don't know where they went but Gary bought them from the guy who owned Electric Radio when he sold to Ray and moved.

You mean TMC GPT-750?

yep that's the one.  a T3 on steroids.   But, ya gotta have the AM modulator to be rare.

Bet one brings a high price when it is for sale.

Not really rare or uncommon. Was around for several years and we sold thousands of these rigs.

WRL Globe Trotter.  Designed by Ted McElroy, licensed to Leo Meyerson, who immediately got threatened with a lawsuit by RCA, claiming they owned the "Globe Trotter" tradename.  He convinced them to allow him to use up all of the 1000 front panels he already had made up.   But I don't think he sold anywhere near that many before discontinuing the unit, since so few seem to exist.  Worlds heaviest 40 watt rig!

Is that a pack of smokes in the compartment for scale?

Saw one of those at the AWA meet a few years back, would have picked it up, but was pretty ratty and don't need another project, still, looks like a neat little rig.
But didn't Meyerson design it, and McElroy sold it.
I know that Mac was a big CW man, always thought of Leo as the design guy.
Figured it was an add on to the line of other products sold by Mac - keys, bugs, oscillators, etc.
Interesting tidbit on the RCA issue, makes sense.

Where did the Stancor go OM?

Yep, I have one, but the mod deck is HB - pair of 813s driven by a quad of 807s in class A.  BT-500 mod tranny and reactor.  The mod deck was built by N4VMY (SK) and I bought the rig from another SK's widow in Tennesee, not too far from K4KYV's.

Jared W1ATR has one (AKA "The Iron Curtain"  ), so does Brown W1NZR.  I met a young guy at the Carroll Cty MD hamfest several years ago that was going thru one that had the SSB deck.  Howard Mills built a mod deck for someone (don't know where it is now); W2XR has one with the SSB deck I believe; he's in the process of restoring it.  W2VW had one or two, and Gary W7FG (SK) had several.  There's a guy in MD who used to work for TMC that had no less than 3 in his basement.

They show up on eBay from time to time.  They seem to float around from person to person seldom making it on the air, which is a pity.  They're basically plug 'n' play, even if you are saddled with the SBE sideband exciter, from 160 thru 10 (160 mod requires cutting a STRAP on the final tank coil).

Here's a pic of mine

Thanks John--I imagine when one comes up on eBay it is big bucks and PU only of course!  that has to be the ultimate non-homebrew AM Rig for a ham.

[w3jn]

The last one I saw, with a very ugly HB mod deck with a black wrinkle face that didn't match the rest of the xmitter, went for about $300 on eBay.  A steal.
