Thanks Duane. The coupling between the pcb traces that run between W2 and J9
and between W3 and J10 are the main cause of filter "blow-by" in my K2/100
#3255. If I did not use my K2 in SSB mode, I would be tempted to cut them.

Hey Gang,
Is anyone using the 100 watt amp shown on the Elecraft "Hands-On" page?


Tnx,
