Not sure if this is were i post it or not. I have two Motorola hand mics and three Throat mics. All mics are BRAND NEW. I do know they will work on Motorola SX-700 radios, But i am sure they would work on other radios also. Not sure what all models they will work on. But you can not go wrong for $20.00 plus shipping for all 5 of them. Would also do trading for them. If you have something you would like to trade, Please let me know? Thanks
