My son-in-law does IT work for a local Christian FM station, which has recently developed a pronounced hum after a thunderstorm last week. I'm not an engineer, and I've not listened to this station lately. They are having their engineer stop by in the next week or so, but this got me curious: Again, I know this could be wide-open, but I'm sure many engineers on here have dealt with this repeatedly. Does it sound like the transmitter is, and I'm showing ignorance here, 'out of phase'? Perhaps the storm had nothing to do with it except as a coincidence, and we have to consider the sound card. Again, I'm curious...what could it be, pros? Thanks in advance for taking the time to respond, if you do!
