Have you tried 105.3 FM? Its on Wiki and nothing is said about being off the air (when I wrote this). Could be they are having AM transmitter problems, IDK...
They've been sold off by CBC Broadcasting to a liquidation manager to pay off debt. I actually found this new out on Facebook of all places.
"Ronald Cohen’s CRC Broadcasting Company transfers Business/Conservative Talk “Money Radio” 1510 KFNN/105.3 K287BX Mesa and Sports “1580 The Fanatic” KQFN/95.9 K240EU Tempe AZ to liquidation manager MCA Financial Group. MCA’s purpose will be to sell the stations as quickly as possible to repay creditor Desert Financial. KQFN also simulcasts on LPFM Broadcasting’s 99.3 K257CD Phoenix."
