Effects of Frequency & Earth Conductivity on the Groundwave Propagation of AM Broadcast Stations

Below is a link to a paper showing the effects of frequency and Earth conductivity on the propagation of groundwaves in the AM broadcast band.

The study confirms the physical reality that for long propagation paths and some sets of conditions, an AM broadcast station radiating 1 kW can produce greater groundwave field intensities than a 50 kW station.

Your posts always seem to be a statement of fact (or opinion), but never a question... what gives?

Not always. I have answered or commented on the posts of others, also.

My goal in this case was to post information that perhaps was not obvious, or well-known -- a tip, which seemed appropriate for posting on ENG-TIPS.COM.

Thank you for your interest and evaluation.
