The antenna was shortened to optimize it's use at this higher freq. The output wattage remained at this lower figure (about 35 watts). I suspect this is due to the radio operating outside of design parameters. Perhaps tweeking the VCO would get this back where we'd like it. I don't have a service manual, so I haven't messed with it. This would explain why the radio performs perfectly in the HAM bands, while possibly putting out less power in the higher business bands. Something to consider.Happy motoring, Tim</blockquote>
