?  Certainly.  Also, a ham radio operator who is also a MARS member is 
allowed to run c. 10db more suds (than the ham limit) on certain MARS 
frequencies.

?  Meanwhile, just across the border, in Canada and in Mexico, the limit 
is 1500w PEP.  
Also, our brother Mexican hams can use SSB on 30m.

?    The apparent intent of the bureaucrats is to ban ham radio 
amplifiers that can be driven with FCC type-accepted CB radios.  However, 
serious CBers purchase general coverage ham radio transceivers and FCC 
type-accepted ham radio amplifiers.  It takes little time for a 
semi-technician to wire around the official CB-filter in such an amp., 
tweak the 15m tuned-input, short a turn or two on the 15m tank inductor, 
and the amplifier is ready for maxi-suds 27MHz operation.

?  I think it doesn't matter, Jim.  How are the FCC's bureaucrats going 
to prove that you built any of the monoband amplifiers in your shack?   . 
 As I see it, the main things are not to cause interference and not to 
cause injury or discomfort to feathered friends who might alight on our 
aerials.  .
