And noticed the number of call letter changes they've gone through in the last few years: currently KGDD, and he lists "EX - KFXX / KKSN / KZNY".
FCCinfo.com lists:
Call Sign History
KGDD from 03/15/2004
KZNY from 11/17/2003
KKSN from 04/01/1998
KFXX from 09/12/1989
KSGO from 09/01/1984
KYXI from ???
I know, from my 1960s DX days that they went from KGON to KYMN to KYXI back then.
That makes 8 sets of call letters. Can anyone think of a station that has been through more sets of calls?
