Several times in my adventures working on broadcast transmitter sites, I’ve walked in on a facility absolutely roasting itself to death because the batteries died in a digital HVAC thermostat.
Today was another one of those and it was the strangest. I’m not even going to try to explain what the hell happened because I don’t even know, but I can tell you that apparently, the Maxiva XTE exciters react by just turning everything into a bad game of Numberwang.
In all seriousness though, one exciter developed massive phase noise which led to viewer complaints of not being able to watch the channel, and the other drifted off frequency and wouldn’t go back. I wonder if it’s got packing foam glued over the oscillator like the old Apex?
