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?
A former engineer (who was eventually banned from the facilities for various people problems including throwing a chair at a DJ) had made dozens of these splices where almost anything that’s an analog stereo pair goes into an electrical tape covered Y connection into some kind of 4-wire shielded cable.
Out of curiosity I unwrapped the tape from one of his splices to see what was inside.
Oh, no. No no no no no no my entire facility is wired like this no no no no NOPE FUCK AAAAAAAAAHHHHHHHNOPENOPENOPEARONIWITHCHEESENONONONO
And yes this does look like the right meter– EMD just put it behind a panel, likely with a small lamp behind to light the face. I’d post the link to the original if I could find it, but it seems the metadata on railpictures.net just doesn’t match up for me to find it. The picture is of an EMD GP7 cab.
