Accidents, mistakes, mishaps and other tales

Lets get started:

Results of a deer vs automobile accident

Results of a deer vs automobile accident

It does not look like much, however, that is about $5,500.00 worth of damage. What you don’t see is the mashed oil cooler and radiator. This happened on my way from one place to another during the early morning hours. I was traveling at about 55 MPH when a deer bolted from the woods and entered the roadway from the right. I did not have time to break.

In a ditch

In a ditch

A momentary lapse of attention causes loss of $80.00. I think I was adjusting the defroster as I was driving down the road when suddenly, I felt the car tilt over to an alarming degree. You can see the tow truck getting ready to pull it out. Fortunately, there was no damage to the vehicle.

Troubles with the neighbor

Troubles with the neighbor

This is on the access road to one of our transmitter sites. The station has a legal right of way through this property, however, the neighbor seems to object. I spoke with him and showed him a copy of our deed, he has since changed plans.

One side of a balanced audio connection disconnected

One side of a balanced audio connection disconnected

This is the downside of using category cable to make audio connections. The wires are not as rugged as say Belden 8451. This was causing problems because it is at an AM studio/transmitter site.

Burned 30 amp three phase contactor

Burned 30 amp three phase contactor

Three phase, 30 amp, 240 volt contactor installed in a 480 volt system. Lasted a few years, anyway.

White face hornets nest

White face hornets nest

New tenants on one of our towers. This is a white faced (or bald faced) hornets nest. They are really paper wasps, but that difference aside, these beasts are nasty, aggressive and have a painful sting. Normally, I am a live and let live kind of person, but in this case, they gotta go.

Dummy load attached to plywood

Dummy load attached to plywood

This is at one of our AM clients site. Somebody, quite some time ago it seems, made this test load for a 1 KW AM transmitter. It is very nice, carbon ceramic resistors, 50 ohms and surprisingly little reactance. Then they attached it to this piece of plywood. As one can surmise, the load gets quite hot under full power, full modulation conditions. We remounted this in a cage type enclosure and bolted it to the cinder block wall.

Scala PR-950U cross polarized

Scala PR-950U cross polarized

The client at this station is complaining of intermittent STL drop outs and low signal strength at the receive end. Found this Scala PR-950U antenna mounted for vertical polarization, but the antenna element is horizontally mounted. We’ll call it “vorizontal.”

Ribbon cable from a Cummins 135 KW generator

Ribbon cable from a Cummins 135 KW generator

This was discovered during routine maintenance and thankfully not during a power outage. Mice got into the control box of a newish Cummins 135 KW generator and chewed through what looks like a data buss cable. The generator would not run and the cable and control board needed to be replaced.

Bulging capacitors

Bulging capacitors

There is more bulging capacitors removed from flat panels monitors.

And so on…

  • Ooowww, regarding the contactor:
    Owned.
    … Pwned.
    …. SCONED.

    Um, yes, that contactor is Well Done. At least that one was open air so when the arc flash hit it didn’t simply detonate it like the 240v breaker on 480 that I had explode right next to me.

    I’m also loving the plywood cooking dummy load and the Vorizontal antenna. Fabulous! That thin mylar(?)+foil ribbon cable has never been one of my favorites… even where it’s used for laptop keyboard interconnects I’m wary of it causing weird failures.
