Table 3 Band Frequency Limits
Do not operate the amplifier with the band switch on a higher band than the indicated
range. Doing so will cause harmonics that will exceed the FCC limits and cause
interference with Amateur and other services. Do not operate the ALS-1406 in the 6-
Meter position on any of the other bands. Damage to the filter board can occur.
Caution:
This amplifier has an FCC mandated automatic disconnect and other features
preventing 27 MHz operations. There is no available circuitry or control provision to
circumvent this lockout.
MARS or CAP Operation
For licensed amateur radio operators participating in Military Affiliate Radio Systems or
Civil Air Patrol, 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.
Ameritron guarantees to exceed FCC Part 97.317 harmonic suppression standards
inside the
amateur bands
listed in the table above.
Ameritron does not guarantee
harmonic suppression or operation outside amateur bands
. Most commercial
services prohibit use of non-commercial radio equipment.
This amplifier is
inoperable
between 26 and 28 MHz. Modifications allowing operation
in the 26-28 MHz range is not available, irrespective of licensing or end-use.
