Courier 23+ won't key up

Post by adamf » Monday, 07 August 2017, 13:46 PM

Hi all, I have a Courier 23+ in Excellent shape, was sitting on the shelf for a few years and was working but went to try it and it won't key up. Receive is fine but won't transmit. When I key the mike it makes sort of a buzzing noise but will not key. It is NOT the mic (works on another Courier plus I tried 3 different mics for the Courier 23+ but all the same. I even swapped out the relay with a good working one but no different. I looked the radio over inside but can't see anything so hoping someone may know what the problem is? Thanks for any help. Adam

If the relay isn't closing it is the cap. I don't have a schematic for the Courier but the buzz or hum is a capacitor that helps hold the relay closed during transmit, I can't tell you which one it is.

Thanks Greg, I was thinking it was a cap, perhaps someone can tell me which one it might be? Again, thanks for any help. Adam

Just a quick note, I tested it again to see if I could determine anything and when I key up it is the relay that is buzzing. Again, the relay is fine so it is something else. Adam

So the relay clicks into transmit or not clicking over at all?

Hi, no transmit, it just buzzes, no clicking. Thanks, Adam
