200w from a ts430:blink:, i think you need a new wattmeter,
they will do about 160w if somebody has been in with a golden screwdriver but thats not doing the radio any good at all, 100-120w is more than enough for the components in the bandpass filters and pa board,
stock they do 90w fm and thats hard on them too if your long winded,
if it was mine i would set it back to factory power settings and use an amplifier if 100-120w max aint giving you wood.
