It's a Radio Systems TR-20 in very rebuildable condition. The only obvious thing that I can see is R102 on the power output board is missin' the wiper. Beyond that, Idunno. I never plugged it in. It's been sittin' in a box since the late 90's and was in service up until that time. (Installed in '79) It was havin' issues with poor range and I figure someone tried to tweak it and broke the pot. Instead of repairing it, they just replaced it.. (I know a little of it's history) Manual with skimmies/parts list included..
I'm lookin' for a frequency agile FM stereo xmtr with an external antenna connection to cover my property that can operate on 12 v.d.c. (I don't have city slicker power) I would like to make a trade but I'm willin' to donate to a worthy cause.. (Coupler Not Included. I didn't get that.)
Admin.. If this is in the wrong place, I apologize..
Some pics..

sent you a follow up contact. i can solve your fm problem for you. contact me for more details
The R102 is the BIAS adjustment which, I have learned from RFB, is very important to the proper working of the TR-20 and several LPB models. I don't think the transmitter should be used until that pot is replaced.
I would really like to see kc8gpd get hold of that transmitter, he's been trying longer than most people would to get something that works in his living situation.
Good luck to all.
Told kc8gpd that I'd ship it as soon as I can. I see him bein' "On-The-Air" real soon! Glad he has a use for it..
I've gotta 100' Rohn self-supporting tower (5-20' sections) that I'd let go of if anyone wants to come and get it..
A 100-foot tower would be an absolute dream but.....
I can't.
No.
No way.
Got to stop thinking about it.
It would look so neat standing back in the back.
That's really high. Higher than the trees. Above the rooftops.Visible from miles away.
I wonder what could be put up there? A C.Crane FM transmitter?
Does it need air-craft lighting?
lighting is required over 200 ft or when in proximity to an airport
Should have it by the weekend or early next week. (via UPS) Enjoy!
I am very eager to hear reports from kc8gpd about his experience with carrier current. It is a whole other beastiality.
