Nope, the rules allow 1000 watts output, there is no ERP limit on
amateur radio. You could theoretically have one million watts ERP
legally. consider hams who do moon bounce. The real limits though are
those imposed by the limitations on automatic controlled digital
transmissions (it's poorly phrased and limts it to a bandwidth of 500
Hz, that's right half a KHz in US CFR 47 part 97.221) and the
requirement that stations use the minimum possible power to carry out
communication. RF safety considerations also likely crop up in any such
discussion and hams are required to ensure that the public is not
exposed to rf above a certain level.
