Same observation here in Cy-Fair. Have not heard any sign of KVGK recently. And 97.3 is a timeshifted Hum FM (I think they call it Hum FM Rewound, or something similar...which raises the question: Should this have a separate originating station?)
While on the subject of 101.7, I still have not heard anything out of KQEU when in its supposed coverage area. I don't think the station has ever been on the air.
Also while discussing LPFMs: Still nothing from KOHV 99.5 and KJFI 102.5 in NW Harris County.
