![]() SWR Protection prevents amplifier damage if you switch to the wrong band, use the wrong antenna or have a high SWR. The attractive desktop amplifier unit weighs only 22 pounds. The operator-friendly layout fits nearly any station configuration. Must present FCC license at time of sale. 10/12 Meters available to licensed amateurs with an optional kit (MOD-10MK). Fan speed is regulated by temperature sensors, assuring minimum noise for adequate cooling.ĪLS-1300 runs up to 1200 Watts of clean SSB output power (just 100 Watts drive gives you the full rated 1200 Watts output) for continuous coverage between 1.5-22 MHz. Its cooled by a whisper quiet cooling fan. ![]() The ALS-1300 RF deck operates from 50 Volts for efficient, low distortion linear RF power service. They not only are more difficult to cool, if one transistor fails they all have to be replaced. This concentrates all of the heat in one small package. Some FETs actually are a package of several transistors in one large case. They are properly arranged to spread out the heat over a large surface, something that other amplifiers using a single power device cannot do. Ameritrons eight FETs are mounted on the dual heavy duty heat sink. The reliability of the ALS-1300 is insured by using eight rugged MRF-150 power FETs. Get instant bandswitching, no tuning, no warm-up, no tubes to baby and no fuss! The AMERITRON ALS-1300 is a solid state near legal limit FET no-tune Amplifier.
