[Elecraft] KNB2 non-operation

[Sverre Holm]

-----Original Message-----
The problem with checking most noise blanker is generating the necessary
test conditions to see if the operation is correct. Most radio equipment
manufacturers are rather vague in this respect and I have yet to find a
piece of test equipment that will provide interference pulses on demand.

The best test signal for the KNB2 is to scratch Q21 or Q22 with a
screwdriver. See the archives e.g.

Good luck and 73
