Right on Tom. There is some merit in the strategy of calling higher speed CQs (30-35) until you run out of higher speed responders, then progressively slowing down. Cuts down the pile-up a bit. Bob

Everybody's right! There are many who, like me, agree with the necessity for verification, but value the QSLs more than the listing. I have certs from WIA for 'Worked All Australian Call Areas on 160

You could also try center feeding the dipole with one leg horizontal over your property, maybe with a drooping end, and drop the other vertically to near the ground with a horizontal run to finish of

Many years ago operating at 4U1ITU I worked a station on 160m who said he was using a whip antenna on his balcony. Exploring further I found he lived at the top of an apartment building and the shie

Hi Eddie: If you excite a lossy tree the RF is dissipated. If you excite an adjacent mast the RF flows and the mast radiates - it will destroy or enhance the pattern but it will radiate. The RF in a

I remember there were such tests many years ago (around 1980 maybe?) and there did not appear to be any advantage in the higher frequency. At the time NM7M expressed the opinion that 2.0 MHz being f

Assuming the 1.8 and the 2.0 MHz signals arrive from the same horizontal azimuth, the fact that the comparison of strengths is different for different antennas seems to show that at least one of the
