Hi guys
Just to share some information about Florida & New England. First time I hear about it was 1997, several QSO's on 432. Then I learned QSO's on 1296 MHz from Florida and Cuba way up to W1 W2 land. Last QSO I know about was W1ZC NH and WB4OMG in FL. This path opens every year or two in October. When I asked Dick how he knew about the opening, he said the APRS map was red down to, and he started to call CQ on 432.
APRS does help if you call CQ.

Hi Jay
The APRS map was what got everyone in a panic as it showed red (good) from Syracuse NY and Ottawa down to Florida in a long thin line. New England was out of it. I suspect it was only showing locally enhanced propagation along the front line. I wish I had a good way to determine tropo inversions. It was great when Don Kent was the WBZ weatherman. He had real weather maps with isobars. Today the weather people tell us what to wear and to get out your galoshes or umbrellas. The Hepburn maps are good but do miss things. Still it is a good guide for places to watch, as the weather patterns are very evident with his data. I also look at the NWS site, but it can get quite confusing if you do it casually. TMI!
Thanks for the report. Your results coincide with my observations. A 500 mile path is very different from a 125 mile path!!
