Chesapeake Beach,  MD - left center of map.

Optimism has struck me that VHF propagation may be
something to look for, so I've put up a NASA AIS
Engine receiver up at my Alexandria QTH.

Certainly connecting it to my Diamond antenna tuned
for the ham bands will work just fine for 162 MHz
signals.... after all, I can copy NOAA weather radio.

OK, so that's just moored at the DC waterfront, just off
by bike commute route. Google coughed up
so I know what to look for...

But I am hoping propagation will get me some DX signals
from the Atlantic Ocean. Anyways, my computer is now
waiting patiently...
