Could someone ask John VP5/K9DX to move at least 1 kHz from 1823.5 tonight. He was nearly on ET3PMW last night and Paul's frequency has been published in several bulletins, so I would not like to cha

Far more significant than power coupling is takeoff angle (TOA) differences between low dipoles and verticals. This is what causes the typical large differences observed of >10 dB depending on path.
