I often use NOAA Weather Radio broadcasts as propagation beacons.
I listen and note which weather stations are coming in from far away places.
From these observations, I can tell where my own signals might be heard
when operating my ham radios on 2 meters (144 to 148 MHz)
just above the FM broadcast band (88 to 108 MHZ – and –
just below where weather radio broadcasts take place (162 MHz)
I began with a nationwide map of NOAA weather radio stations that you can find at:
and edited it into a handy 8 X 10 printable form
for use by DXers on the East Coast of The United States.
Feel free to distribute it and print it as you like!
