This is completely dependent on the user-radio's implementation. Some rigs may not require two "channels" be used, but may have a default mode (digital or analog) and you have to press a button to switch, etc. But PS folks typically like their "channels" -- so that's mostly the implementation you find out there today... -- Nate Duehr, WY0X [EMAIL PROTECTED]
