MARS or CAP Operation
For licensed amateur radio operators participating in Military Affiliate Radio Systems or
CAP, this amplifier is suitable for use on all frequencies between 1.8 and 54 MHz with
some precautions. The upper frequency limits are in bold type in the table above. Do not
operate above the bold-type frequency limits in the table above or PA (power amplifier)
or filter damage may occur.
This amplifier has significantly cleaner output purity than FCC part 97.307 requirements
(January 2016) when operated
inside all amateur bands listed in the table above.
Ameritron does not guarantee harmonic suppression or operation in applications outside
standard amateur radio bands.
