Found a problem with the Icom 2820 dual band radio I have in my car on Thursday night, where the microphone stopped working.
Upon investigation, it looks like the microphone socket, (which is an RJ45 socket), has come loose, causing the connection to be become intermittent.
Looking inside the case, the socket is held by a couple of tiny plastic lugs, one of which appears to have broken.
When I’m feeling brave, i’ll have to solder the connector back to the board, and then somehow secure the socket so it’s not loose. Either that, or I’ll send it back to Icom to do it for me.
