gar fla said:While skywave and groundwave are two different things, you say skywave is not affected by ground conductivity but what about the ground conductivity where the skywave skips?
The last time I was over on the east coast of Florida was years ago and it was the Miami area. One thing I remembered was that New York stations at night came in much better than they do over here on the west coast. While the reception was skywave, isn't the better reception there because of the skip on nothing but water?
Very interesting questions, and I can't say one way or another whether strong ground conductivity helps skywave. An observation: Here in Texas, we have some of the best ground conductivity in the country but skywave interference is horrible because of all the southern interference.
Where I grew up in Ohio, it's middle-of-the-road conductivity but the DXing was and is a lot better ... far less interference up in that part of the country.
