There are very few signals receivable at the moment because of the 
incredibly low (i.e. non-existent) sunspot count, but there is SOME 

I monitor 10.149.2/10.149.4 (actual mark and space freqs for 30M APRS) 
   24/7  from my QTH in Pasadena, CA and plot what I hear on a map of 
the entire continental US.  You can see it on my personal UIview web 
server here:


Note that I have an absolutely horrendous local noise level here  (S9+10 
broadband white noise level from a leaking cable TV trunk) which 
severely limits what I can hear.     Most days I DO hear 3 or 4 stations 
regularly during the 2 hours around local sunrise & sunset, when 
propagation is best.  As I write this , the last station heard was W7CCY 
in south central Washington state at 16:24 local (Pacific) time 
today.    The regulars that I constantly hear through my massive noise 
level are:

W7CCY    (He seems to have some sort of gold-plated magic antenna system --
                    I hear him consistently even when I don't hear 
ANYONE else!)

When ever the sunspot count kicks up to a non-zero value, I immediately 
see several more routinely.  

A month ago, on my annual cross-country trip from CA to East Lansing, MI 
and back, I heard a lot of stations from the mobile  (FT-857 into W6HIQ 
"Hi-Q" screwdriver ant) all along the 2000 mile route, day or night, 
once I got out of high noise level urban areas.
