[Elecraft] KNB2 diagnosis

[Don Wilhelm]

Stan,

Scratching Q21 is certainly NOT a *fix* by any means!!!  It is a 'GO -- 
NO-GO' test only.
BUT it is one 'no-tools' method that can effectively produce the noise 
that the KNB2 is capable of suppressing.  Of course, the preamp must be 
on to bring Q21 into the circuit.
