Last few times I tuned across KVGK they were having audio problems or were transmitting dead air.
I think a lot of LPFM operators are discovering the reality that 100 watts at 100 feet (or much less) covers very little in a sprawling metropolitan area, especially in an overcrowded FM band where co-channel interference is a headache. And many such operators lack the money to keep going, or are totally clueless about how broadcasting works from an operational and financial perspective.
I also see that KPSR-LP 99.5 in Pasadena also had its license cancelled earlier this month. Not sure if that one was ever actually on the air.
The LPFMdatabase website includes listings of cancelled LPFM stations, and there are a lot of them--many of which never made it on the air.
