I'm new to this whole forum world so please be gentle. From reading another thread I learn't that in order to program a motorola radio such as the GM339, one needs an equivalent or later version of CPS than that which was last used to program the radio (irrespective of the S/W version of the radio). In my case, the "SW Version" is "R03.15.00" and the "CP Version" is "R7.01". Does this mean I need to acquire Professional CPS Version 7.01 or later? I'd like to be sure before I shell out the cash to make this radio useful. Thanks in anticipation, - Daryl
