Trying to get a piece of CB History working

[Crambone]

Don’t know if anyone is familiar with Eagle Clubs? It is like a Moose or Elks and back in they day they had base CB radios in the lodge that were manned 24/7 during times of bad weather or emergencies. I cam across a radio, antenna (part of it) desk D104 mike, call sign plaque, members roster list, pics of the radio being used and awards the club was given. The club was in NC I can’t recall the town but I have the info somewhere.
These clubs still exist but in small numbers but they no longer have cb clubs.
Ok the radio was a Lafayette Telsat 1140. I want to get the radio working and I can use a bit of knowledge.
It wasn’t working at all and after I replaced a diode and recapped it, it know turns on and receives but the receive is extremely low.
When I key the mike I get the red TX light and I see my signal on the radios meter with audio but I get 0 out of the antenna.
I know it’s hard to diagnose a radio online but any suggestions were to look would be appreciated. I have most equipment needed to check stuff but I am still in the learning phase.

Not much schematic info online, some of the Lafayette rigs were Cybernet chassis. A Telstat Base I worked on once has that funky VCO sealed circuit . No matter how much I adjusted it , receive and TX was low. Long story short, electrolytic cap sealed in epoxy in the VCO block likely culprit. Not saying this is the issue but a shop in Oz makes replacement boards for that circuit .

Well...The local cb clubs for the most part are history true...But there's still "CB BREAKS", and get-to-gethers and shoot-outs...

One Break that is a annual event is the "Channel 28 Good-time Gang" break in Manchester TN the last weekend of June...It's a 4 day event which starts on Thursday and runs threw Sunday (although most people are leaving on Sunday, so not much happening other than good-byes till next year!

BBi has a Break too, and there's some others, but only one I have ever gone to is the Good-Time Gang break in Manchester TN...other than some local ones.

To find out more about Breaks, Just check around on the Forums and the fb sites, usually Breaks get posted several months before to give people time to make hotel reservations and plan vacation time or just travel time.

Fraternal Order of Eagles. They claim credit for establishing Mother's Day.

A 1978 car that starts, but won't idle and dies when you let your foot off the pedal would suggest maybe more than one thing is wrong. Even if you already replaced all the plugs, wires, points, fuel filter, hoses, belts, etc.

A 1978 radio may have more than one problem even if all the electrolytics are new.

Starting point for an old 40-channel radio is to make sure the radio's PLL has proper control of the channel frequency.

Easiest way to do this is with another radio set to the same channel. Transmit on the other radio and see if the Lafayette can hear it. If so, the receiver trouble may be bad alignment.

Next, key the Lafayette and see if you hear anything in the second radio. A coax jumper plugged into your 'monitor' radio can be used to "sniff" for transmit signal by poking it into the transmit section of the Lafayette.

Seeing that the slug-tuned coils are peaked properly is one of the first-up troubleshooting steps for a radio that is on the right channel, but has gone weak or dead.

Service data for this model is in Sams volume CB-215. Probably not posted free online anywhere. Sams will sell you a photocopy.
