Sometimes it is the seemly small insignificant detail that will take a station off the air. To expound on that a bit, I have my own story which happened yesterday. \u00a0The back story is this: \u00a0About three years ago, some unauthorized tower climbers climbed the WICC south tower all the way to the top. \u00a0The station remained on the air at full power while this was going on. \u00a0Once at the top of the three hundred-foot tower, the climber, we can call him “Crack Head,” managed to loosen, then remove the beacon and throw it to the ground. \u00a0Mind you, this guy had no safety climbing equipment whatsoever and he had to stand on the top plate, which is all 20″ x 20″ square, of which the beacon takes up 16 inches. \u00a0A two-inch purchase between himself and eternity demonstrates that God does indeed smile on fools and drunks.<\/p>\n\n\n\n

\"WICC<\/a>

Fortunately, his friend on the ground had a video camera and filmed the entire episode. \u00a0Even better, they then posted it on Youtube. \u00a0 The police took interest in this video and its owners because the damage to the radio station was significant, and with the tower being about a mile away from the end of the Stratford Airport runway 17, presented a real hazard to air navigation. \u00a0Needless to say, the video was used by the prosecution and both crackheads are now in prison, God having limits after all.<\/p>\n\n\n\n

A spare beacon was hoisted to the top of the tower and placed in service. \u00a0This beacon was quite old and leaky and continually failed, burning out the tower light flasher. \u00a0Thus, it was time to replace it. \u00a0We took advantage of the outstanding weather and the crew from Northeast Towers made quick work of it. \u00a0Removing and lowering the old beacon to the ground, then hoisting the new beacon up and installing it. \u00a0I goobered it by not taking pictures of the beacon fixtures flying up and down the tower. \u00a0I took the station off the air for about five minutes to check the condition of the wiring going up the tower, making sure there were no shorts up the tower or back toward the transmitter building. \u00a0While I was doing this, I overheard the two-way radio conversation between the tower climber and the ground crew on wiring. \u00a0It seems the old beacon had only two wires, hot and neutral. \u00a0The new beacon had three wires, hot, neutral, and ground. \u00a0Tie the neutral and ground wires together, instructed the tower boss.<\/p>\n\n\n\n

Nothing more was thought of that, it sounded okay to me. \u00a0Unfortunately, the tower had other ideas. \u00a0About an hour after we secured from the job and drove away, the station went off the air. \u00a0It seems the neutral wire was not referenced to the tower previously. \u00a0Because now the neutral wire was tied to the top of the tower, the RF found a path to the ground via the tower lighting choke at the base of the tower. \u00a0It started arcing to its access door causing the transmitter to go off around 4 PM. \u00a0Equally unfortunate was the fact that the construction gate was closed and I had to get a boat ride with the harbor master, which took about an hour to arrange. \u00a0The entire situation was further complicated by darkness, which comes predictably around 6:30 PM this time of year.<\/p>\n\n\n\n

When I arrived back out at the base of the tower, I took the metal access door off of the tower light choke cabinet.  I could see the fresh track marks all across the bottom of the door. With the door off, I turned the transmitter on.  Worked just fine.    I tried cleaning it off with a Scotch Bright, but to no avail, the transmitter would not run at any power level with the door in place.<\/p>\n\n\n\n

Finally, the harbor master becoming impatient and darkness quickly falling, I taped a garbage bag over the tower light choke box with the door off and turned the transmitter back on.  The tower crew will have to come back and remove the ground wire on the beacon.<\/p>\n\n\n\n

The first rule of troubleshooting: Check the last thing that was worked on first.<\/p>\n\n\n\n
