[Boatanchors] 10/11 METER AMPS

[Glen Zook]

The only "modification" required is to attach an
antenna, ground wire, etc.

If someone were to really press this point, then just
changing out the fuse with one of a different type or
current rating, or replacing the power cord, or even
removing one screw from the unit would constitute a
technical modification!

Also, the restriction for modifying or building any
linear is for one design type.  If the builder even
substitutes a component value then he/she has
"technically" built a different linear if the linear
is homebrew.  If the linear is commercially
manufactured, then an amateur can modify similar
linears so long as they have different model numbers,
manufacturer, etc.  Even something as small as a tube
number difference, a changed capacitor or resistor
value, etc. constitutes a "different" amplifier.

In addition, the individual amateur could modify one
amplifier on December 31 and another one on January 1
of the next year (following day) since the limitation
is per "calendar year".  Of course, then that
particular amateur could not legally modify any more
of that EXACT model until January 1st of the next
year.

So long as there is any difference at all between the
linear amplifiers, a licensed amateur may modify one
of each per calendar year.  If there were that many,
he/she could modify several of different types of
linear amplifiers every day for the entire year.

The restriction is not for "one" amplifier that was
originally built for some other use (i.e. illegally
for 11 meters), but is for one of that EXACT model. 
Again, the slightest difference legally makes the
linear into a different model.

Thus, if a linear were marketed as "Linear type A",
then if the manufacturer were to make some slight
modification and call the unit "Linear type A-1", that
constitutes a separate model in the eyes of the FCC!

As stated later, if an amateur licensee modifies one
for use at his station, it is legal but he may only
modify one during a calander year.

>From the original email, he has not yet modified the
unit so it is not legal. If he decides to put it on
the air on 10 meters to try it out, he is then in
violation of the rules, unless he modifies it first.
