An excellent video. I can't believe you went to all the trouble of changing the main board just to provide a working set - that's excellent customer service!
Dear Richard, isn't this much too much effort for a radio set you yourself think is crap? I admire your patience and the end result is as allways nice... but still. Throwing it in the bin takes a second, repairing it took 5 days? Could you explain in the next video why these Yorks are so bad? My respect sir for pulling this off!
It took 5 days of 90min sessions, not 5 actual full 8 hour days! It belongs to Alan, our mystery benefactor who has & continues to be very kind & generous to us, otherwise it's wouldn't have been done. These sets can sucessfully be used in a car, but are difficult to use as a base station as they easily pick up RF enegy from the base aerial (especially ours) & it gets into the power lead & microphone cable. It's poor design & poor beta testing at factory level. The Signal 1001 & Lucas ACB888 version of these (with the other PLL to make mattery worse) are really bad on receive too. They are the only CB radios that the ground RADAR at RAF Cranwell four miles away interferes with receive! Anyone who collects UK FM CB radios needs to have all different models including crap ones. The On-The-Air test was so bad with hum, that I'm going to set up a secondary test to prove these sets can work OK under the right circumstances.....before publishing the test video.

I would charge so much to sort out the mess, a customer would scrap it! Changing the resistor on the input of the dual-gate MOSFET at the front end for a new metal-film resistor improved sensitivity on my one of these, but it was 30 years ago.

We probably end up doing that about twice per year.

A very mammoth job, I look forward to the on Air test.
bzzzzzzzzzzz hmmmmmmmmmm say again...You love it :(

"Triggers Broom" sprung to my mind 😊

The world's most expensive 867 😊
Channel Free light like the Murphy.
Resistor gone down for the led bulb ?
hi 👋 richard good luck repairing the york jcb 867 cb 27/81 uk fm cb radio from paul chapman at east sheen 73's
Thanks Paul,
Richard
@@ukfmcbradioservicingTango21 to richard you are most welcome looking forward to the air test From paul chapman at east sheen 73's
Hello Richard, what model of frequency meter are you using, brand and reference?
It's part of the Marconi all-in-one radio test set I use.
Richard
@@ukfmcbradioservicingTango21thank you very much Richard
