Overview of Amplifier
Capabilities
It is extremely important to thoroughly review the Installation and Operation sections of this manual
before attempting to use the ALPHA 99. Failure to do so could result in serious damage not covered
under warranty.
Continuous RF Output. The 99 is capable of 1.5kW continuous RF output on all
commonly used modes and on any authorized amateur frequency from 1.8 to 29.7
MHz.
Compatibility with popular amateur transceiver and exciters. It requires
approximately 50-55 watts peak RF drive for 1.5kW output.
Capable of full CW break-in, QSK and all digital modes when used with any
appropriate transceiver.
Protective functions built in. The control system incorporates protective functions
that minimize the probability of accidental damage to the amplifier or its power
tubes. In most cases, when one of the protective functions is “tripped,” the
amplifier will go to Standby.
Optional auxiliary cooling fan available. We recommend using the external
auxiliary fan for extended RTTY or other “locked key” service. This is available
separately from Radio Alpha Products. The cooling fan is required for operation
with a 50Hz power source.
