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!!

K2CKA FM06 was only about 6 dB stronger than normal 'flat condx' on 2
meter SSB last night. Nothing else of interest noted. Either APRS map
was optomistic or there was no southern activity.

Hi Al & vhfers
The 10 GHz guys are all excited about the red blob this morning, but
there is no activity. When I quit last night just before 02:00,
the red
blob was looking quite impressive. It went from VE3 down to
Florida in a
thin line. It is there this AM but not as pronounced. It would be
really nice to hear reports from others who were inside the "blob" to
see how it related to their experience with typical CW and SSB paths.
The APRS map is generated by (obviously) APRS signals that are
typically low power small gain antennas so their coverage is quite
small. Such signals are heavily influenced by local conditions where
inversion layers will provide huge improvements within say 200
miles but
no farther. Our situation, with higher power and bigger antennas
already provides the gain needed to extend coverage well beyond those
short ranges.
I am reminded of the experience of Ross Hull back in the early
1930's
on the 5 meter band. Modulated oscillators and whips were the typical
setup. Coverage was 15-20 miles. Ross had been to Brandt Rock,
South of
Boston and saw a telephone company radio link that used a high gain
array to cross Cape Cod Bay. He duplicated that array on his 5 meter
station located on Selden Hill in West Hartford and immediately
started
contacting hams in the Boston area all the time. They all thought
he was
a bootlegger as no one had ever heard signals from so far away. All
because he put up a big antenna! His coverage went from LOS
paths to
diffraction and tropo scatter range immediately. This revelation got
him on the road to discovering the mechanism of tropospheric
refraction.
I was well out of the path of the big red blob but did note some
slight
enhancement on WA3EOQ. We are talking about maybe 5 dB on average.
On a
500 mile path a 5 dB improvement sure comes in handy as signals
are very
weak. Path loss is around 240 dB +/-. I did work N2SLO on Long
Island
in New York and his signal might have been a bit weaker than normal.
Not sure how to explain that. Maybe a case of path QSB alone.
Maybe we
worked on a QSB trough!
So did anyone note any anomalous long haul contacts during the
evening?
Inquiring minds want to know.
