KPA500 protection

[Bob McGraw - K4TAX]

The KAT500  to KPA500 configuration as shown on page 5, Figure 1, in the
KAT500 manual allows one to then use the the KAT500 Utility to set the 
Default Amp Key Interrupt based on SWR value.  I find this method and
configuration works very satisfactorily.

"How does a LP100 protect against stupid errors?"

LP-100A is designed to open the key line when SWR exceeds a user defined threshold.  When I make a mistake it is often the first to trip.
