This WAS a rubber stick on cushion. These are often found as feet on electronic equipment. I actually don’t know why it was ever in there.
It didn’t stop there and ran all the way down the chassis. The first sign of trouble was that I went to pull the scope out of its housing and it just stayed stuck, but then came out with a big SCHLORP sound.
I’ve begun ripping these rubber cushions off my older electronic gear and replacing them with sticky back felt feet if necessary. I wonder if there are silicone rubber equivalents? The silicone rubber keypad on this oscilloscope still works fine despite being made in the early 1990s but that superfluous cushion had to go before. I’m glad I got it before it oozed right out the holes in the back.
As nasty as this would be I’d rather soak in that substance than the contents of the Tesla Dumpster Pool
It’s been far too long since I’ve posted here so I figured I’d gather an important collection:
TV and radio station related vehicles I’ve murdered in the line of duty!
#1 – the Q97 truck. This was my first time ever going up a nasty little dirt mountain road and the truck just… unceremoniously shut down on me right then and there at a switchback in the road. After it cooled down for a few minutes, it restarted and worked just fine. The fault was never identified or replicated by anyone else, but we decided after that incident that it probably shouldn’t go up to the transmitter site again.
#2: The Nissan Frontier that couldn’t take RF.
It made it to the top of Shasta Bally perfectly fine, but as soon as I got back in it, turned it so its back was to the KNCQ-FM and KRCR-TV transmitters, and started driving back down, it decided to shift from 4WD to 2WD. When I tried to shift it back to 4WD the transfer case motor started moving and then halted in a neutral position. An “ATP” light came up on the dash which is apparently the warning that the transfer case is in that neutral state and the transmission’s park pawl won’t do anything to make the vehicle stay put.
It was downhill from this spot where the truck died to a space about a hundred feet away, so I coasted it down there and power cycled the whole thing, which was the point at which I found Nissan’s ONE GOOD DESIGN FEATURE:
Those quick release connectors come out of the bottom of the battery positive terminal, uh, conglomeration, and it’s easy to disconnect them to kill power to everything. The big red wire that remains connected is the starter I guess. After it sat to think about its place in life for a while, it was willing to work again.
On a side note, here’s an important warning about Nissan pickup trucks, and it is likely to extend to other Nissan vehicles. I observed this same behavior on two different Nissan Frontiers and one Nissan Titan of three different model years. When you downshift the transmission to descend a long steep grade, it will automatically shift back up to drive and then start upshifting with no user input OR INDICATION on the dash after 15 minutes.
You get no warning that this is about to happen, it’s just suddenly… clunk and you’re accelerating downhill way too fast.
The only way to reset this is to stop, turn off the engine, and restart the vehicle!
#3: Ford Econoline van I seem to have no photographs of. Blew up SPECTACULARLY while hauling a load of e-waste to a recycling center. The transmission began slipping just before I got there and the cooling system went off with a “POP!” sound and dumped everything out in a flash as soon as I stopped. With absolute seriousness, I asked which bin to push it into and leave it there.
#4: Ford Econoline. Is anyone surprised? Heater hoses blew off where they go into the firewall and the coolant dumped. By this point in time I’d gotten tired of faking it with that dark brown and decided to embrace my natural rainbow.
Down in the river delta this morning, a circuit breaker went TWANG, and eventually, an engineer went HHHHHHHHHHHHHHHHHHHHHHHHHHHH.
The Space Station Toilet transmitter dumped one cabinet. While I was waiting for one of my coworkers to get there on site and see why it wouldn’t come back up, the first order of business was to remote in and change the combiner mode so the dead cabinet was no longer in the system (which caused a large amount of power from the other two surviving cabinets to get dumped into the combiner reject load due to the mismatch).
The Space Station Toilet is an older generation of Harris transmitter using their old eCDI user interface system. Their newer stuff uses a weird looking but far easier to use interface which does not require FECKING JAVA (!!!!) and has a nice block diagram sort of layout. You can see it in action here on a HPX series FM. Since it’s natively designed to work great on touchscreens, the newer GatesAir TV rigs come with a cute little pull out shelf where you just set a generic tablet PC in there to use as the front panel UI. But uh, eCDI is a confusing dated looking mess, and its design contributed to an… incident.
I went in there, took the dud cabinet out of the combiner on the mode tab, then noticed cabinet 1 had no IPA power or beam voltage. I decided since it was not working correctly to switch it back to BG heat until it could be serviced.
BG heat is kind of a keep warm mode that leaves the ESCIOT tube filament on at reduced voltage, and I think also leaves the ion pump on. It’s basically a warm standby that keeps the filament ready to go, and helps maintain the hard vacuum while the tube isn’t actively online. Well….
Two minutes later I got a call from our director saying “hey, we’re off the air, and I think it’s because you did the same thing I did…”
Sure enough… Note the two screenshots. See the difference?
Blink and you miss it. It’s not the difference of which button is selected at upper right.
The issue is, if you’re in the HPA tab at the bottom, the Beam On / Standby / BG Heat / Off buttons affect the state of one HPA cabinet, as selected by the 1/2/3 buttons. If you’re in the TX tab, guess what they affect the state of….
KERPLUNK. FLUSH. BEAM OFF. ZERO WATTS. ENJOY BUSH’S BAKED BEANS.
Beans. Mmmm, beans.
The day this thing is to be decommissioned I want to see what happens if I fill the cooling system and high voltage power supply cabinets with beans and turn the transmitter on one final time. BEANS ON, BABY! Mwahahahaha.
Citrix posted this really feel-good cheeky shit to Twitter and I had to be a smartass and reply about how a lot of businesses are exploiting work from home to sneak extra work into every hour of employees’ days …
…. And then a company that makes surveillance spyware for companies to use on their remote workers comes along and fucking likes my reply.
