In addition, the HL-450 requires 50W drive for full output.  The 10 W
rigs will not be able to drive it beyond 70-80W output - not 200.

>> Looks like RM Italy is an option for mobiling with the KX3 and a mid range power boost. All others seem to weigh in too heavily in power and cost. Unless a KPA100 is available sooner than expected, will either delay the KX3 or pick up the RM Italy.
