? 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. .
