Hi Markus
My IC-R75 (X-tal oven) is in REV CW mode and the pitch is 600Hz .
My frequency scale is calibrated after the time station on 77.5KHz
(599.90Hz in the waterfall). LA4ANA's beacon is 7.6Hz over the pitch
freq in the waterfall. I hope I am not thinking 180 degrees wrong now,
but this gives me 137787.6.
Markus, is it possible to estimate the hight of reflection layer , when
you know the frequency and the doppler shift ?
