Storm Stopper

Seen after I emptied out its jackpot…Cyclone is a really kinda old game now, I remember first seeing them in the early 1990s. It’s still fun as heck and I can usually get the jackpot on it unless it’s been set to evil mode.There’s a hidden adjustment as to how easy it is to get that jackpot. The clock that advances the light that’s on runs at least 32 times as fast as the lights stepping around the table. The “winnability” adjustment can be set so anything from all 32 clocks all the way down to one will actually win. If it’s set particularly hard you’ll often see the game do evil things like reverse from the jackpot light you stopped it on to the one before it. It’s not subtle about the fact it’s dicking you over.When it’s not set to evil though it’s just pretty and fun to play.Speaking of games of skill… I spotted impending Rifa Madness in some video distribution amps at work.I’m using them as an excuse to get the 25 year old nightmare fuel out of there so I don’t have to fear the black burst signal being pulled out from under us. I was trying to upload an image of the waveform but the photo just won’t pass through Comcrap, so here’s an unrelated thing

Well, somewhere, engineering was attempted

Here’s a supermicro that pissed us off this week. It’s from 2015 and clearly got dumped on us as the result of a certain “text-that-gets-scrolled-on-the-bottom-of-the-news” vendor cleaning out back stock when my workplace ordered a new system.

Blaarffff. It literally seems like the bios doesn’t like certain monitors, and you have to fight it for hours to get video. You’d think with a vendor like Supermicro you’d get a board built with better parts but this thing looks like a damn Soyo. Remember Soyo? They drove themselves out of business by delivering dumpshit. This Supermicro sure looks like overpriced dumpshit complete with “hey look it’s 2001 again” capacitors.

Snap, Crackle, Pop! Triax Crispies.

I’ve always found the old school triax connections used for some studio cameras….. charming. Triaxial cable looks mostly like a RG-6-ish coax with another dielectric layer and another braid over it, with the end result looking a bit more like RG-11… until you see the freaking WEIRD connector it terminates into. It’s like a ginormous shell around a BNC. Trust me when I say you do not want to be coiling this cable up and have the connector fly over and smack you in the— uhhh— output spigot and terminating resistor. OW. But anyway—

Cameras hooked up by triax can be powered over the triax. To do so, the Camera Control Unit (CCU) sends a high voltage – 120-170 vdc I think, down the cable, between the outer and inner braids. A DC/DC converter inside the camera powers it and any ancillary equipment like lights hooked up to the 12v output it provides. It works great, but you MUST ensure that the voltage has been removed from the cable before unplugging it. On some systems, it seems like powering down the camera tells the CCU to stop sending that voltage (or it drops to just a few volts – just enough for it to power whatever onboard the camera tells the CCU that the cam is connected and requesting to be powered up?). Anyway— at my old station I had a few instances where someone would unplug the cable hot and it would make the camera mad or even carbon-track the plastic inside the connector.

Today I found out what happens if the cable ITSELF gets angry:

tri-axial foaming cable

From top to bottom: The outer jacket with subtle black mark from the fault within, the middle dielectric and inner braid, and the outer braid, which frayed then burned in half at the fault location.

The ridges are from the connector’s strain relief. This fault occurred right behind the connector, where the cable was getting flexed a lot.

The CCU reported the cable was shorted out, and this was confirmed by a resistance reading of about .15 ohm at the connector on that end as measured by the onboard multimeter on a Tektronix 2236

All three elements of the cable – the center conductor, inner braid, and outer braid were shorted together.

I was able to lop off the end of the cable and remake the connector. The connectors we had in stock were circa 1996 and were made by Kings about, oh, two corporate umbrellas ago. Currently they’re under Winchester Interconnect and Winchester has no documentation on the connector including what the strip lengths are for the layers of the underlying cable. Canare and Cinch have different takes on the same thing. I managed to get it back together with new parts for the center.


The center is pretty much a crimp type BNC. Not shown, the….. ridiculous oldschool clamp thing used to hold the outer braid to the connector body, nor the giant ball-bonker connector body itself.


Not sure if it’s the world’s most perfect installation, but hey, it passed the Smoke Test and the camera’s back up on it and in service.

So spell out “I M A G E Lightbulb”…

Hey look, there’s a CYX bulb…..

And it’s terrifying

The pins are about 3/8″ diameter and the whole bulb is 8 1/4 inches high overall with the light output centered 5″ above the bottom. It has an average life of 300 hours. The normal application has it inside a Mr. McLargeHuge stage fresnel safely locked away behind a big thick glass lens and a metal screen. I don’t even want to think about it too hard.

For a small $945 you can get a VisionSmith ReLamp module that lets you replace it with a 275 watt LED that pays for itself *rapidly* in reduced air conditioning and power costs…

Discontentment at RF Central

Several years ago, I worked for a TV station in Miami that had gotten a bunch of Eurotek microwave STL and ENG link radio units out of the Sprint/Nextel MMDS rebanding deal. Apparently, at the time, Sprint’s tradeoff to get the spectrum was that they had to provide new 2 ghz microwave ENG gear to any TV station whose stuff would have been obsoleted by the new bandplan. Some stations got a different one, others got the Eurotrash, I mean, Eurotek.

We had quite a few of them, all in relatively non-critical service. One of our older engineers there was trying to keep them all alive but his success was limited as the 2 ghz and particularly the 7 ghz units liked to lose reference oscillators which were made of pure Unobtainium.

The units had constant cooling issues that led to a lot of power supply and amplifier failures too.

I mean, don’t get me wrong, it was a kinda cool platform for its time… all modular and a 1U mainframe could contain any mix of transmitters (upconverters), receivers (downconverters), power amplifiers, ASI stream multiplexers or demultiplexers, and can even interleave general purpose data over the connection and make it available via standard Ethernet ports on either end.

Unfortunately it’s about like most other Italian RF gear I’ve worked on, which is to say……. questionable garbage.

Bok-AWWW, Sacramento

I heard some happy crowing in the studio this morning and went to investigate.

“Sir, are you aware you’re a rooster?”

S H 🐣 🐣 K

Yeti the rooster and Patty the duck were wonderful guests and gave us all plenty of happy butt wiggles and little chirps.

420 smoke semiconductors every day

Did I ever mention that I’m glad I don’t have any Screen Service rigs in my care?

These RF Central ENG microwave rigs are quite enough thank you!

I dunno, Italian transmitters aren’t my cup of tea, but at least they’re leaps and bounds better than PissTek. 😉
