Ameritron's revolutionary ALS-600 is amateur radio's only linear amplifier that uses four rugged TMOS RF power FETs -- gives unequaled no tune solid state poerformance. It includes our no tune FET Amplifier and a 120/220Vac 50/60Hz AC
power supply for home operation.
You get instant bandswitching, no tuning, no warm-up, no fuss! ALS-600 gives 600 Watts PEP Output power and 500 Watts CW with continuous coverage 1.5-22MHz; 10/12 Meters with easy-to-install optional kit. (FCC License Required)
SWR Protection prevents amplifier damage if you switch to the wrong band, use the wrong antenna or have a high SWR. Over-power protection enables if output forward power or reflected power exceeds a safe level. Output power is
automatically reduced to prevent amplifier damage by controlling ALC to exciter.
The ALS-600 is extremely quiet. A low speed, low volume fan is so quiet you'll hardly know it's there, unlike noisey blowers used in other amplifiers. The ALS-600 is a compact 6" x 9«" x 12" -- takes up less space than your rig!
Weights just 12« lbs.
An illuminated Cross-Needle SWR/Wattmeter lets you read SWR, forward and reflected peak power simultaneously. An Operate/Standby switch lets you run "barefoot", but you can instantly switch to full power if you need it.
You get a front-panel ALC control! This exclusive Ameritron feature lets you adjust your output power on the convenient front panel display. You also get front panel Transmit, ALC, and SWR LED indicators. A 12Vdc output jack lets you
powr low current accessories. Enjoy 600 Watts of no tune Solid State power. Call your favorite dealer for your best price.
Butit gets even better than this! Do you want to place even the main ALS-600 amplifier out of the way? Do you want the ALS-600 to change bands automatically when you change bands on your transceiver? You now have these options. A pair
of RJ45 remote control jacks on the amplifier permits ALS-600 to be controlled either manually by the compact ALS-500RC Remote Control Head, or automatically by the ARI-500 Automatic Band Switch. The Automatic Band Switch reads band data
from your transceiver and automatically changes the ALS-600 bands as you change bands on your transceiver.
