[Elecraft] K3 RF Feedback Recommendation

[Don Wilhelm]

Phil,

I don't know if it is 'official' or not, but I would highly recommend 
you jumper KIO3 L7.  An RF Choke in the signal return path is just 
asking for the return lead to respond to many forms of noise (including 
RF) and couple it into the circuit.

73,
