Josh,
If one insists on using ALC for amplifier protection, set the level well
above that which will cause ALC to reduce the driving transceiver's
power during normal operation.
Most well designed amplifiers provide adequate self protection and
should not rely on ALC to reduce the drive in the case of a fault. If
the amplifier design relies soly on the use of ALC to provide fault
protections, I would call that 'risky design'. If it is the primary
means of protection, that is an example of poor design IMHO. To rely on
an external device for such protection is to rely on a device that also
is subject to failure - in other words, poor design IMHO.

Just to clarify... use of ALC with the PW-1 is not to adjust drive
power. That's a bad practice. You MUST use the ALC line because the
amp uses this as a primary means of protection. Without ALC, a fault
condition can damage the amp.
