Has anyone here ever done one? Is it a pain wjere is the best place to order one? I have a few distributors but looking for ideas ;)
 

Its a neat little radio and I dont really meass with CB radios but I like this like the Uniden PC-122 I had basically the same radio same circuit board ETC. Im gonna put the Expo Expander N Kit I have in the radio but the LED for channel is horrible just like the TRC-465 and PC-122 radios all evetually had. So I want to get the display fixed first then while the radios open Ill ad the Expo board. I thought about just adding a frequency display unit but the radio is pretty neat and I wanted to fix it right ;)

I know some radios had resitor banks behind the display that had 4 680 Ohm resistors and the resistors would go bad but Im not sure this is the same I have to open it up and see and I actually have about 100 680 Ohm resistors that I ordered a few months back for a different project because I had a few hundred resistors here but no 680 Ohms and know they are common in running with L.E.D.s so I ordered a bunch.
 
I removed the display from the radio and literally cut the channel read out of the display, retaining the S meter. I hand wired a double seven segment display to the pins of the cut off portion, I think it was common anode, and reassembled the radio works very good and the new display will not 'burn' out.
Befor you ask, I used a hacksaw.... :blink:
