[Elecraft] linear amp shutdown (was ALC)

[David Cutter]

In my view there are 2 issues here:

1   in my view the amplifier should be self-protecting against overloads, eg 
antenna fault (I am mindful of virtually any other equipment which must be 
tested by law with overload conditions)

2   ALC has its problems and thus not always connected, but everyone uses 
PTT which can be very easily disabled (allow the rig to self protect) or tx 
inhibit, tx enable, or others?

ALC is an analog signal for gradually reducing drive, which might not be 
appropriate for shutdown.
