So once again I was asked to look at one of our transmitters as after it got split, reconfigured, unsplit, and put back on air, it was only making 75% power… then suddenly, 50%. Very weird. Faults showed an intermediate power amplifier not working, but why? After trying to swap it I noticed one of the power pins on this weird connector at the back had kinda fallen into the module. Here’s the connector and the back of the module.
The connector is a DB 5W5 which is modular and lets you field configure it for whatever floats your boat. In this case it’s four big high current pins and one RF connector.
After not having any luck swapping the module and noticing it seated kinda weird, I called up GatesAir support and was asked to inspect the matching connector on the backplane.
Well There’s Your Problem, they’re all BURNINATED.
Here’s the inside of the module from when I opened it to reseat the pin.
I told my director of engineering about what I found and I’m pretty sure his response was:
The parts quote was $1900 for the backplane and they still haven’t quoted me for the part on the modules. To be honest I don’t think they even like talking to me at all, even when I’m just being a proper friendly person just trying to make wattage.
Then I learned that my director of engineering just resigned. He’s going over to PBS. I’m really happy for him but trying to think of how we’re going to reorganize has me all
Anyway, an afternoon run up to the forest, a day off after spending so much time on that transmitter, and some kitty cuteness helped quell the possum hissing.

A PissTek fan? No wait. Remember how I said I like how radio doesn’t have graphics systems? This video card’s fans both locked up and killed a big monitor wall. The video processor for this is a single point of failure (of course) and the wall is pretty much the entire news set (of course). These frameless fans are of an unobtainable size but I found that an 80mm x 10mm fan would fit here. These are also vanishingly rare but I was able to get some that Digi-Key still has…
