[Elecraft] KPA-100 RFC 10 question

[Don Wilhelm]

Werner,

The new T/R switch design eliminates RFC10.  It was a source of trouble 
because it could cause a 40 meter parasitic oscillation.  That problem 
was usually noticed when operating with a KAT100.
Do not install RFC10 in the updated KPA100.

73,
Don W3FPR
