John Smith quoted someone:
"A 5 KW amplifier is not lawful for use under Part 97."

Back in the 60's, a ham friend of mine ran a
surplus AM transmitter capable of 10KW output.
However, he never adjusted his input power to
more than the legal 1KW limit.

Whom, ever "Someone" is, he isn't versed in 47CFR97, and doesn't
understand, or can't comprehend, the actual Rule that Part 97
operations are REQUIRED to operate under. Specifically Part
97.313. I wonder if "Said Person" has ever actually READ
47CFR90.313? Apparently NOT......

For all you disinterested parties

TITLE 47--TELECOMMUNICATION

CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION (CONTINUED)

PART 90_PRIVATE LAND MOBILE RADIO SERVICES--Table of Contents

Subpart L_Authorization in the Band 470 512 MHz (UHF-TV Sharing)

Sec. 90.313 Frequency loading criteria.

(a) Except as provided for in paragraph (b) of this section, the
maximum channel loading on frequencies in the 470-512 MHz band is as
follows:
(1) 50 units for systems eligible in the Public Safety Pool (see
Sec. 90.20(a)).
(2) 90 units for systems eligible in the Industrial/Business Pool
(see Sec. 90.35(a)).
(b) If a licensee has exclusive use of a frequency, then the
loading
standards in paragraph (a) of this section, may be exceeded. If it is
a
shared channel, the loading standards can be exceeded upon submission
of
a signed statement by all those sharing the channel agreeing to the
increase.
(c) A unit is defined as a mobile transmitter-receiver. Loading
standards will be applied in terms of the number of units actually in
use or to be placed in use within 8 months following authorization. A
licensee will be required to show that an assigned frequency pair is
at
full capacity before it may be assigned a second or additional
frequency
pair. Channel capacity may be reached either by the requirements of a
single licensee or by several users sharing a channel. Until a channel
is loaded to capacity it will be available for assignment to other
users
in the same area. A frequency pair may be reassigned at distances 64
km.
(40 mi.), 32 km. (20 mi.) for Channel 15, Chicago; Channel 20,
Philadelphia; and Channel 17, Washington, or more from the location of
base stations authorized on that pair without reference to loading at
the point of original installation. Following authorization, the
licensee shall notify the Commission either during or at the close of
the 8 month period of the number of units in operation. In the
Industrial Radio Services, if the base station facility is to be used
by
more than a single licensee, the frequency assigned to it will not be
reassigned for use by another facility within 64 km. (40 mi.) or 32
km.
(20 mi.) where applicable for a period of 12 months, Provided, That
the
facility is constructed within 90 days from the date of the first
grant,
meets the loading standards to at least 50 percent within 9 months,
and
meets all loading standards within 12 months.
