[NLRS] Rain Scatter

I suspect that the determination between "tropo continental" and
"transatlantic" or "transpacific" tropo is where the majority of the
propagation path occurs.   For instance, if 10% of the path is over water
and 90% over land, which mode it is, or visa versa.    Without looking at
the articles that Garys pointed to, I would guess that the majority of the
W1LP/mm to WB6CWN path was over land.     The good news is that here in the
midwest, we don't have to address this issue (unless, your talking about
some really really big time DX !! ).    Interestingly, there is no 10 GHz
record listed for the transatlantic nor transpacific modes (see the North
Texas Microwave Society DX records listing at
http://www.ntms.org/DXRecords.htm  (the W6 to KH6 path isnt listed on 10
GHz)).

Is 800+ miles possible on 10 GHz continental tropo from here in the Midwest
??   Is our classic stagnated high pressure late summer tropo mode capable
of a supporting long haul 10 GHz ?   Key to finding out is being prepared
for those somewhat rare big time tropo events.     For those with
aspirations for 10 GHz DX, it may be good to know who has 10 GHz capability
within the "tropo belt" and that live 800+ miles away (with a list of phone
numbers).

Jon,

What is the definition of Continental in this case because isn't DL34 out
in
the Pacific ocean SW of Baja?
