I'm sorry if it embarrasses you, but exploitation of part 97 loopholes, has
resulted in greater tightening of part 97 rules.

As illustrated in the FCC doc and from experience, there is no law
prohibiting the act of a licensed ham transmitting from a transmitter on the
ham bands as long as it meets the emission standards in part 97. Put your
own serial number on it and call it your ham radio.

The problem is with offering for sale, a transmitter "capable of
transmitting from 400-500 mhz at 4 watts" without a FCC ID plate for that
range.

I know of a ham dealer who avoids all problems by requiring a callsign prior
to sale. If there are discussions regarding "mods", discussion and
transaction is terminated. If there is discussion of "mods" after the sale,
they are referred elsewhere unless they have some NTIA approved reason for
it. There is new NTIA policy to close that loophole also. All of these
abuses are resulting in the targetting of ham regulations to close up
loopholes.

This is a gotcha when buying import radios. None of the radios can be
legally sold here unless they have FCC approval, unless they flat don't
transmit. Consumers and Commercial people who buy stuff that can't pass the
tests are completely screwed with no recourse or remedy except to rat out
the US dealer.
