Congratulations on your purchase of a professional-quality Alpha 9500

linear amplifier.

1.1 Product Description

The Alpha 9500 (see Figure 1-1) is an self-contained autotune HF linear

power amplifier. It is capable of continuous operation at 1500 W peak

power output on single sideband (SSB), keyed continuous wave (CW),

slow-scan television (SSTV), radioteletype (RTTY), digital modes or

FM, with no time limit.

CAUTION

CAUTION! Study this manual carefully before operating your

amplifier for the first time. In particular, it is extremely important that

you thoroughly review the installation and operation sections. Failure

to do so could result in serious damage not covered under warranty.

1.2 Product Capabilities

Product capabilities include:

•Continuous RF output. The Alpha 9500 is capable of 1.5 kW

continuous RF output on all commonly used modes and on any

authorized amateur frequency from 1.8 to 29.7 MHz (other than the

60-meter band).

•Compatibility with popular amateur transceivers and exciters. The

Alpha 9500 requires approximately 50-65 W peak RF drive for 1.5-

kW output.

•Capable of full CW break-in, QSK, and all digital modes when used

with any appropriate transceiver.

•Built-in protective functions. 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 goes to standby.

•USB and serial interface allow for remote operations, diagnostics,

and firmware upgrades.

1.3 Safety Considerations

•Locate the Alpha 9500 where there is good air circulation all around

and on top of the cabinet. The unit may become hot during operation.
