Hello Markus:
 
Do you see any signal level variation = in a 24 h=20 period?
 
About the radiated power, I=B4ll take = into account=20 the correction, thanks.

Hi Jos=E9,

though it is not = explicitely=20 mentioned in the caption beneath Geri's and Gamal's curve, I think = their data=20 actually mean a power of 40 kW EMRP (i.e. 125.6 dB=B5V/m at 1 km). = Here at 310=20 km, I see 70 dB=B5V/m with about 6 dB groundwave = absorption.

Despite this=20 slightly higher EMRP, your measurement would still imply basically = lossless=20 low-angle skywave propagation.
