[Elecraft] K2: Old Filter question - - (underwater noise)

[Geoffrey Mackenzie-Kennedy]

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.
