when I lived North of line A as recent as Nov 2016. the rules stated: Effective 2/16/99 the GMRS rules have been amended and you may operate on any of the primary or interstitial channels shown in section 95.29. Exception: Licensees who operate North of Line A and East of Line C may not operate on channels 462.650 MHZ,467.650 MHZ, 462.700 MHZ and 467.700 MHZ unless your previous license authorized such operations. This is clearly stated on my copy of licenses in Waivers/Conditions. There appears to be no further restriction on RF power outside of those already existing for the GMRS service. I interpret the rules as saying you are allowed the 50 watts for mobile use. The terms of base and control stations is changing this summer so please look to the FCC documents and rules outlined.
