ALPHA 9500 Interim OPERATING MANUAL

www.alpharadioproducts.com

If you are certain that you have taken care of the problem that caused the fault, you may turn the

ampliﬁer back to operate and proceed with use.

6.1.5 Lightning Protection

Induced energy from nearby electrical storms or other power transients may damage

components. Such damage is not covered under warranty. It is important to use a good

lightning arrestor, however the only lightning proof solution available is to disconnect

antenna feedlines and AC power when the equipment is not in use.

6.1.6 Operating in Bypass Mode

Whenever the 9500 is in line, either off, in standby (STBY), or in warm-up with the WAIT LED

lighted, the ampliﬁer is bypassed and the exciter is connected directly to the antenna. The

throughput limit in all cases is 1500 watts.

6.1.7 Transceiver Automatic Antenna Tuner

Many popular transceivers have built-in antenna tuners that are not usually needed when driving

your ampliﬁer. The built-in antenna tuner in your transceiver may be used with care through your

9500 ampliﬁer.
