Hi Stefan interesting...... at that distance could it just be different goundwave v skywave phase at the different receivers. You really need more thn two paths to pin that one :-)) Alan -- Original
Hi Alan, My observation is that the sky wave attenuation at daytime in summer is in the order of 40 dB over that distance. So i think it is groundwave exclusively. Also i can't see QSB over that dist
Hello Stefan, Monitoring daytime reception of NDB's over a sea path compared to a full land path revealed an advantage of about four times for a sea path. 73, Roelof, PAoRDT
Hi Stefan, The way I try to separate ground and skywave is to look at a beacon transmission during daylight hours. the groundwave strength seems to correlate quite well with the minimum in the mornin
