I remember a few things from the old CB days, where you needed a licence to operate a AM/SSB and knew of a mic called an Echo Mic and another called a Power Mic I think it was called, which took a 9 Volt battery in the back of the hand held mic. I heard there was a think called skip too. Days of old hey. I`ll be up for a new UHF soon and was thinking of the Icom.
