Ok Warren

Not sure  what the  land  is like  in Tennessee , Andy  says he was getting 
reliable  wspr decodes  over 400/500  miles , but that  was  from -LF- hams 
, all  the  same , with the  Ae  and  power , that's  going  some .... 
thought  it was a  bit  like 500  , where  compared to  160  , ground  wave 
is  good to  70  miles

If its a  un licensed band  how  did  you  get a  licence ?

Q what dose the  licence  say about  modes  of  emission  (hint > recent 
lofer posts )

73  - G..
