I'm down here in the Mississippi Delta in a bass boat, in hip waders, dodging swimming snakes and checking out transmitter, tower, and studio damage due to the flooding.
It is beyond horrible, folks...to those who have Pike and Fischer's FCC data service on line, get ready for a "flood" of STA's, emergency notices of station interruptions/cessation of operations, studio and transmitter relocations, and the like from down this way. About an hour ago, I sailed by the Tunica, MS casinos...dead quiet with no activity, when we got word of two guyed towers collapsing into the backwaters bayou on tne TN/MS border. Oh, joy...
Anyway, I heard a bit of the WHBE/680 problems before I got the call to action here. It sounded like not only was the transmitter PA not ramping up to daytime power, but the phasor was having trouble switching patterns, too. What make/model/age transmitter(s) do they have over on Mud Lane...and has this phasor's components (inductive, capacitive, resistive elements, coaxial switching, dummy load if installed, etc.) been checked and calibrated?
It sounds to me like the transmitter is looking at a fault in the transmission system and not letting itself go to full TPO as a self-protective measure. Just a suggestion...seen it before.
