Hello José, I found the following results for DCF39, using the CCIR curves: Sea Water, average salinity, conductivity 5 S/m, dielectric constant 70, EMRP = 40 kW. Wet Ground, conductivity 10 mS, diel
Hello Dick: I took a plot, last month, of the transmission of a Spanish colleague, who is in Madrid, at 500 km as well, and the signal level during the day was not stable, varying around 3 or 4 dB; I
Dear Jose, You wrote: 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
Hi Markus and Jose, I have just been looking at the ground wave level at Brian's CT1DRP a little further down the coast. My estimate is based on some concellation fades that occured on Brian's plot o
José, yes. During daylight hours, the level is fairly constant, but at night it fades up and down by perhaps 3 dB, sometimes more. Though that's just from memory, as it's been a while since I last di
Hello Markus: Do you see any signal level variation in a 24 h period? About the radiated power, I´ll take into account the correction, thanks. 73, José, EA1PX -- Original Message -- From: MarkusVeste
Hi José, 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
Hello all 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
