OK, I have 3 inquiries, so here is the reply to everyone:
Both mics are the CMP-23W model.
Both mics are white
mic #1 has a (somewhat yellowed) cord; worked fine the last time I used it 1 year ago.
mic #2 has a black cord, and transmits only, no receive last time it was used.
Th extension cord fits Standard Horizon radios, and as a spare, it has never been installed. It also has a rubber weather
cover for times when the mic is not plugged in.
Thank you all,
