Topband: Daylight QSO's during the SP

[W8AV at aol.com]

There is another aspect to propagation on 160 during daylight hours.   In the 
broadcast field it is not uncommon to experience periods of "skywave"  
propagation during daytime hours, especially during the winter months.   That is why 
the FCC and the Canadian DOC have incorporated a "critical  hours"  period 
(it's called the "transitional period" in the Canadian  Broadcast Rules and 
pertinent bilateral treaties) into the AM Broadcast  Rules.  It is defined as the 
period of time that occurs two hours  after local sunrise and two hours before 
local sunset.  It is possible to  hear broadcast stations from hundreds of 
miles/kilometers away during daylight  hours.  I have even heard broadcast 
stations hundreds of  miles/kilometers with a sensitive receiver during mid day at 
certain times  of the year.
 
It is true that there is a greater number of stations on topband than there  
were years ago and there are better receivers and receiving antennas which 
also  add to this phenomenon, as has already been mentioned.
