1) I have been plotting the signal from HBG using ON5OO's
excellent software, and it confirms what I had from casual
observation. That is an 8-10dB enhancement when the path is in
darkness.
Recording HBG75 last night: >10 dB enhancement here at North
Germany over night, impressive deep nulls right on
sunset/sunrise. I'm using a tuned ferrite rod for 75 kHz
reception since noise floor on Marconi is too high. HBG75 is
bearing approx. 200° from here.
