Hi MF, While there is nearly no chance to leave decodes above 400 km in daylight above land, it seems to be no problem above sea water. As soon as the first hop (?) hits the ground on water, the wave
Hi Stefan, I'm not sure what point you are making here....maximum skywave daytime range is about 1000km so there is no ground reflection. However a receiiving station near seawater can get a "coastal
Hi Alan, Well, it is not a new effect that i've discovered, maybe i should have added this, as usual. I'm here talking about MF, i.e. the 630m band and there is no daytime range of 1000 km above land

Hi Stefan, Maybe the ground-wave propagation curves in this ITU document shed some light? In this document there are curves for sea water (various salinity levels), fresh water and land (various cond
Hello Stefan, About 10 years ago a couple of NDB chasers have been investigating this issue by comparing reception of NDB's over a sea path and a land path. To exclude sky wave propagation as good as
