    Many of the newer Icom HF Rigs come with the AM Carrier Max at 25 watts. Many of their slightly older rigs did 40. The newer ones have 100 Watt finals. Does anyone know if the AM Carrier on the newer ones could safely be turned up to 4o watts from the 25?

    25 watts carrier at or near 100% modulation is 100 watts PEP: trying to get more than that is asking for problems.
    That's the short answer. Soon the experts will chime in and begin to argue.

    Wonder who will quit first this time?

    If they do argue about it, it's a fool's errand they're on!

    You're right, nothing more needs to be said.

    Do the math to see what the difference between 25 watts and 40 watts would be at the receive end. Then decide whether it's worth it.

    Your best bet would be to use a amplifier.

    Most user that have set the power higher have smoked their radio, Then blame it on Icom.

    The answer to whether ICOM's RD70HVF can "handle" 40 watts AM carrier is suggested by OP's call sign : BBQ

    Like the old 75 watt DC INPUT to the final power limitation for Novices. Most Novices had rigs that were rated for (gasp!) NINETY watts!
