Do you see any signal level variation in a 24 h
About the radiated power, I´ll take into account
the correction, thanks.

Subject: Re: LF: DCF39 ERP and field
though it is not explicitely
mentioned in the caption beneath Geri's and Gamal's curve, I think their data
actually mean a power of 40 kW EMRP (i.e. 125.6 dBµV/m at 1 km). Here at 310
km, I see 70 dBµV/m with about 6 dB groundwave absorption.
slightly higher EMRP, your measurement would still imply basically lossless
low-angle skywave propagation.

In the web of Geri, DK8KW, can
be seen that DCF39 ERP is 40KW (22KW EMRP), based on measurements made by
Geri some years ago. For this radiater power corresponds, at 1800 Km, in
function of inverse of distance, 58 dB(uV/m); last nigth I made measurement
of 60 dB(uV/m), so I wonder if still DCF39´s power is the same as before,
and if the previous theorical field strength, with no reflection loss, can
be exceeded some times due to the several propagation factors
