Isn't there an alarm to somebody that goes off if the station is on after it should be off, there should be?
I'll bet nobody in management listens to this station ,that includes the chief engr. It is like so many things today,the customer is asked to do the troubleshooting.
I heard a station down south that was on after sunset , I sent an E-mail to the owner ,via the stations website, "he'd said he'd look into it " ,it seemed to me I was getting in his way,like he knew they were on but didn't care. The station continued to be on some nights off others ,finally they are now off at night. I'll bet that owner or his chief engr never thought "ya know are station should be off now ,its automated ",let me turn on the radio and check to see its all working good ". Assuming they live anywhere near the station !
