John,
I did just that with mine. ?I added a jack on the back of the rig to plug in a 24-volt supply when I¡¯m operating at home.? The 24 volt connection pulls in a relay that moves the PA power from the 12 volt bus to the 24 volt input.? I¡¯m getting
over 10 watts out on voice peaks, and you are right about the heat dissipation.? I¡¯ll be adding a bigger heat sink to the IRF520 this weekend.
Hoping to connect with more BitX¡¯ers on Sunday night !
