It appears that KRVM-AM-HD is not coming back. Likewise for KLCC-HD2.
KKNX 840 AM is a very interesting throwback to the glory days of AM. Apparently they have enough billings to be comfortably profitable. I wish the station sounded better though.
KEHK 102.3 and KNRQ 103.7 are in their 2nd month of interfering with 105.1.
