[Elecraft] KPA500 in RTTY Contesting

[Bob McGraw K4TAX]

The most destructive element to all solid state devices is......... HEAT!

The KPA500 seems well protected and will drop off line if the 
temperature exceeds a preset level.   My only concern regarding pushing 
an amp like this or any other solid state amp to near rated values, same 
for near maximum heat values, what happens if the protection circuit 
fails?   Hopefully the software will recognize a protective circuit 
failure and shut the amp down.
