Operation
This amplifier covers all Amateur Radio frequencies below 54 MHz, as restricted by FCC or
your local governing authority. Once you have established proper connections, please set the
amplifier (Fig. 2, ref 3) to one of the following bands:
Band Frequency Range Notes
160 1.8 - 2.1 MHz
80 3.2 - 4.2 MHz
40 6.0 - 7.5 MHz
30 7.5 - 14.5 MHz USA 30-meter power limit currently 200-watts
20 7.5 – 14.5 MHz
17 14.5 – 22.0 MHz
15 14.5 – 22.0 MHz
12 22.0 – 30.0 MHz Amplifier automatically disables above 25 MHz
10 22.0 – 30.0 MHz Amplifier automatically disables below 28 MHz
6 50.0 – 54.0 MHz
Frequency Limits Table 1
Caution: This amplifier has an FCC mandated automatic disconnect and other features
preventing 27-MHz operation. 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 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.
Ameritron guarantees to exceed FCC part 97.307 harmonic suppression standards, as of January
2013, inside 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 25 and 28 MHz. Modifications allowing operation in the
25-28 MHz range is not available, irrespective of licensing or end-use.
Warning Lights
The ALS-1306 has three primary warning lights in the center of the front panel. It also uses other
standard LED’s as warnings, flashing them in a certain code that indicates problems. These lights
serve the following functions:
ALC: The yellow ALC light indicates ALC output. Flashing is normal when using ALC. A
steady intense light indicates a problem.
Operational faults reset by placing the amplifier in standby. The following table applies to faults:
