ARRL may initiate changing that law. Proud hams could drive that change. 
With current LDMOS devices lots of money can be saved with one stage 
amps. That change would accelerate switching from tube amps to 
technically much more advanced LDMOS amps. Less energy consumption, 
smaller shack space required. Another question is are there more hams in 
USA or CB operators?
