Again it is still I squared R so at a TWO OHM load and 15 amps you would
indeed have 450 watts. The way the BC-610 ran mobile is into a 15 foot whip
so the resistance could be perhaps as low as 2 ohms, negelecting ground loss
which is in series BUT the BC 610 is looking into a fifty ohm load into the
tuner and the meter should be looking at the output. mike
