Hi Don: I solved a similar problem here when tuning K7OX 160m vertical. He
is very close to strong BC stations and the MFJ filter for the 259 did not
solve the problem. I used my old MFJ 202 noise bridge with a battery powered
SW rcvr. It was a Sangeon ATS 803A, nothing fancy. There was no sign of a
problem using this setup. Hope to CU at Hamcom. 73, Dan, N5AR
