Congrats indeed!!

Seconding Rick's comment below -- AM towers make REAL lousy RX 
antennas.   They catch ALL* the front-end-pulverizing noise on 160/80.

"Been there, done that..."   well, OK, not the dxpedition part. But I 
have occasionally at night "borrowed" a few AM "Daytime-Only" auth'd 
stations' towers for the Ham Jones.   Great fun QRP!!!!   ;)

* that is, all the noise in their pattern, which admittedly might be 
more narrow in some elevation angles than the average amateur 
Inverted-L....
