[Lowfer] Propagation

[Lewis Denton]

Hi Guys,
I have a propagation question. According to the list on Loran on 137 KC I am
getting 137.775920 Great Lakes, 137.778542 Newfoundland East Coast,
137.789458 North Central, and 137.781690 Western US. these are the dominant
ones. and they come in best during the day time. do they lower the power at
night or is this changes in Propagation ?
also the noise here is quietest in the morning from say 4:00 AM till about
11:00 AM, this has been for the last 6 weeks on the noise. what happening.
