>Just a very important observation from this morning on 160M using my new MK >V. With my old TS-940 I needed to add 10DB attenuation or a BC filter to >kill the bc stations overload (S-Mtr pinned) at my QTH. // I had the same problem, Arne. The fix was to use a highpass (shunt L, series C) L-network to match my antenna. Even so, the second harmonic was c. 59db down. - R. L. Measures, 805.386.3734, AG6K, www.vcnet.com/measures.
