WSPR.....again

During these "quiet" times I have been continuing my propagation experiments using WSPR.   The following maps show the results of 500 mW into a 148' inverted L longwire antenna up ay 60'.

I'm hoping to get a 200 mW transmitter using a Raspberry Pi shortly, and then we will see what we can really do.
