CB radio quit.......again

[Jack in Alaska]

My 1 yr. old expensive Cobra CB radio quit last week while out fishing. It received but did not x-mit. Really unhandy as that is the local primary communication method using Ch.33.
Using my cell and VHF I got by for the day.
On the beach I found an old Uniden mic in my shed that had the same 4 pin plug. Installed it and volla......it works again. Took Cobra mic appart. Looked good. Sprayed the slider switch with Triflo (can use WD40) and volla......it now works also. Now I have a spare mic.
I have found that CB's are not a real durable piece of electronic equip. It pays to have a spare.

I'm not surprised that the mic went bad. I used to have to have them repaired on a fairly regular basis when I was running the Assistance Van and using the radio for hours on end. The mic would last about 6 months. The radio's were usually fine for a year or two at most before having to replace the final output transistors. Of course I had the final output transistors bumped up pretty good too. I wish I still had a good tech to do that kind of work!

I finally switched to using a modified 10m Ham radio that would transmit on 11m (CB Frequencies). That worked the best (although only legal with the radio on low power :roll: ).

Most of the Uniden and Cobra CB's used to have common Mic plugs. I don't know if they still do. I'll have to see if I can find my old Uniden PC122 to put in the boat. That little thing was a good solid radio.
