AMPLIFIER FEATURES
Rugged devices.
The ALS-600 uses four rugged RF power FET
Fast warm-up time.
The ALS-600 has no vacuum tubes to warm
No tune operation.
Tuning adjustments are not necessary. A simple one knob selector
switch permits operation on frequencies between 1.5 and 22 MHz.
ALC protection.
The output and reflected powers are monitored and control the exciter
ALC voltage. This helps prevent damage to the amplifier.
Front panel ALC control
. This unique Ameritron feature allows easy front panel
adjustment of the ALC threshold to control power output.
Load Error Protection.
The PA load impedance is monitored and the amplifier is
bypassed if the band switch or the external load is incorrect.
Illuminated Power/SWR meter.
The ALS-600 has an illuminated cross-needle peak
reading RF power meter. Accurate directional coupler and peak storage circuits give
simultaneous forward and reflected peak power readings and also indicates load SWR.
Operate/Standby switch.
This switch allows the amplifier to be by-passed for "barefoot"
operation without turning the main power switch off and on.
Transmit and ALC Indicator LED's.
Front panel LED's provide an indication of
amplifier keying by the exciter during operation and ALC output voltage.
12 volt auxiliary jack.
This jack su12v to operate low current accessories.
Thermal Overload Protection.
The transmit relay in the amplifier is disabled if
excessive heatsink temperatures are reached.
Compact size.
The ALS-600 weighs only 12.5 pounds and measures 6"H x 9.5"W x
12"D.
