I spent yesterday on the early stages of removing a two thousand Watt analog transmitter I installed nearly thirty years ago. It was a pretty good little transmitter; I shepherded it through a major channel change, through the original manufacturer changing hands and then passing the device-specific parts replacement/repair off to a third-party, and moving from brand-new to rebuilt transmitting tubes. (Kennetron, by the way, is the last of the independent tube rebuilders and did very good work for us, at about half the price of new).
The OEM and the brand-specific aftermarket guys are gone now, and the transmitter itself has been out of service for nearly a decade. But it wasn't worth removing until we needed the space, which we do. What I'm doing is disconnecting wiring and readying up the transmitter and related equipment; it's on the very last patch of the original gray and green floor tile* in the building, which will require a specialist to remove.
It's something of a trip through old memories, from the time I was trying to figure out a mess of wiring in the poorly-lit rack next to it and, tugging on a wire, launched a very dead bird right past my face to the day I was retuning it and realized the factory tech who'd said, "Oh, the solid-state amplifiers are wideband, shouldn't have to touch those" had no idea I was moving the thing from one end of the UHF band to the middle and I was, in fact, going to have to retune the entire transmitter all the way from the low-level stages to the high-power output. That turned out well, one of my earliest successes at keeping the little secondary station running using mostly what we had on hand or could dig out of dumpster-bound storage.
Some of the parts are destined for salvage but most of it will just join that same "e-waste" storage, waiting for the recycler.
* I wanted to keep the checkerboard floor pattern when we redid the building interior, which made the architect's industrial designer snicker. Nope, we got a nice, bland shades-of-gray pattern. Drop a machine screw and it blends in invisibly.
