I picked a couple of 6m rigs at yard sale yesterday.

Is this a good place to post some pics and ask for help to ID?

sure

Don't leave us in suspense.

Solid built, home brew?

I think its an AM xceiver..?

Heres the other one. I cant find any references on this company. Its a model TR6-12 serial number 116.



Tks for your help..

Better pic

This is not exactly it, but maybe helps point in the right direction:

And I agree that the other rig looks homebrew.

Here's some background on Transcom:

But the photo says "Transcon", no "m". I thought I'd heard of until Isaw that page about the SSB rig.

This looks early. The name makes me wonder if there's a transmitter and converter in there. Tbere were projects like that.

One of your units looks like one that I sold on eBay some time ago. After several inquiries, I never did get a definitive answer as to exactly what it was but I guessed that it was a 6-meter transceiver. Attached are some pics of the unit I sold and here is my description on eBay:

Homebrew 6-meter AM transceiver. It has 13 tubes including two 6146s in its push-pull final RF amplifier. The arrangement of IF transformers suggest a dual conversion superhet receiver. It has an S-meter, a volume control and an earphone jack on the front panel. A microphone jack and separate antenna jacks for the transmitter and receiver are on the rear panel. Numerous stains on its cabinet suggest hard use in a mobile environment. Not sure of power requirements so not tested and sold as found. Worth restoring or use for its many good parts including microphone/ modulation transformer, S-meter, Millen dial, Hallicrafters knobs, converter crystal, T/R relay and much more. From Ham estate sale.

Thanks Max..that looks almost identical inside and out. I went back to estate sale just as they were about to trash the leftovers and saved what I think is the power supply.

Now to find a safe room to plug it all in.

Now you'll have to find the article that homebrew's based on.

I’m not convinced they were homebrew. Too well executed with same chassis, components and design. Maybe prototypes or r&d examples for larger corp.

We may never know..

Back in the late 50's and 60's, homebrew projects were very well documented with detailed part specifics, dimensions for holes, bending of metal, etc. Lots of VHF publications were floating around during that period, besides CQ, QST, and 73 magazines, GE Ham News, RCA ham tips, Radio Handbook, ARRL VHF book, and probably a host of others.

The question in my mind is why is there a receiver input jack and a receiver antenna jack. If this truly a transceiver, there should be an internal relay to switch between the internal receiver and transmitter.

Good points, I suspect you’re right. Mine doesnt have the additional rcvr jacks. Here’s comparable views to the ones he posted. There is a relay in back behind the finals.



Maybe an early kit..pre heathkit days

The transceiver uses 6146's. They were introduced in roughly 1952.
Heathkit came into the market place in the late 40's. Bears no resemblance to any Heathkit style.

I really appreciate all the help and inputs. Its my hope to get it on the air.

Heres the underside. If these ARE homebrew, I want this guy to build my house.

Considering that this piece of equipment was probably built roughly 70 years ago, I probably wouldn't want him to build my house today
You might check some of the capacitors for the date code to get a rough idea of age.

It's interesting that I don't recall a lot of dialog or construction articles for 6 meter transceivers (receivers, converters, transmitters, transverters - YES) back in the 50's but it could be just my memory fading. The amateur radio manufacturers like Gonset, Knight, Allied, Clegg, and host of others, including in the garage manufacturers, were all churning out 6 meter rigs. Cycle 19 was in full swing in the latter part of the 50's which generated a lot of 6 meter interest. There were also a number of VHF publications, that included a lot of homebrew stuff, which also came out around this time.

As far as great construction, there was a lot of that during that period of time. Parts were available and cheap. Great ideas were floating around everywhere (no facebook or twitter to screw up your brain). And many had great assembly/construction skills. Even my construction skills weren't that bad 40 or 50 years ago.

There was a transceiver, I think 6 and 10, in one of the RCA Ham Tips. But yes, little advantage too building a whole rig.

At home, use a converter with an existing receiver, then build a transmitter. In t?he car, a converter into the car radio. I suspect the "Transon" is a transmitter and converter in the same package, based on the name.

AM or CW transceivers didn't share much, they were transmitters and receivers in one package. Only with SSB was the circuitry really shared.

One thing I keep thinking about is a receiver club project in CQ in the late sixties, maybe written by Irwin Math.The coub decided having a monitor receivervwas a good idea. But then there was a followup article, various hams packaging and customizing, and some built them into transceivers.

But not like this.
