In his recent posting, Ron, WA6DGX states that Orlando sunrise is 45
minutes later than New England sunrise. According to ON4UN's software,
it looks like a lot less than 45 minutes for CQWW:
Nov 1:
Boston Orlando
1116Z 1136Z 20 minutes
Dec 1:
1152Z 1159Z 7 minutes
For ARRL, it's more like 30 minutes ...
Feb 15:
1141Z 1204Z 23 minutes
Mar 1:
1121Z 1151Z 30 minutes
By the way, on Dec 1, Orlando sunset is 75 minutes later than Boston. That
ought to be worth a few JA's on the high bands, at the expense of some EU
on the low bands.
Conclusion: While there may be some ionospheric factors negatively
influencing the N4WW 15 meter performance early in the opening, for
CQWW it is NOT the difference in sunrise time.
