KHOG RF Combiner

1 September, 2002 (17:00) | DTV, HDTV, Projects |

Since a new tower had been erected in 1997 with HDTV in mind, it already featured a broadband RFS panel antenna used to broadcast the analog channel 29 and was capable of accommodating the future DTV channel on UHF 15. The trick after expanding the building and installing the HDTV transmitter was to combine the […]

HDTV Transmitter Installation

1 September, 2002 (17:00) | DTV, HDTV, Projects |

For this facility (KHOG) the gain of the antenna was considerable so that only about 10kW TPO would be needed to meet the maximized ERP level, so the choice of a solid-state Diamond transmitter from Harris was made. The benefits of this choice were that the multiple modules and power supplies allowed for considerable redundancy […]

HDTV Encoding Rack Design

1 May, 2002 (17:00) | DTV, HDTV, Projects |

Here is a project I am justifiably proud of. Our corporate engineering management had determined that we were to use a Harris Flexicoder as the core of our HDTV encoding, but outside of that we were to determine what we needed to best integrate it into our facility. Initially, I was not pleased with the […]

HDTV Infrastructure

1 October, 2001 (16:00) | DTV, HDTV, Projects |

Prior to installing the coming DTV transmitters there had to be a manner in which to get the HD signal to the transmitter. Since we would ultimately have two high-power DTV transmitter sites and they are a considerable distance from the studios, the only practical solution would be to encode the HD signal at the […]

KHOG Transmitter Building Expansion

1 September, 2001 (17:00) | DTV, HDTV, Projects |

In order to accommodate the additional transmitter equipment for this station’s HDTV transmitter the building had to be expanded considerably.  I was able to include in the budget enough area for a sound-resistant office where maintenance records, spare parts and test equipment could be kept and calls could be made without having to shout over […]

KHBS-KHOG-TV Ice Storm of 2000 and 2001

10 January, 2001 (18:00) | TV |

What follows is a blow-by-blow retelling by Larry Friddle (my Asst. Chief Engineer at the time) on 10 JAN 2001 of a very difficult and stressful couple of weeks where everything seemed to be going wrong and the weather was definitely set against us… My name is Larry Friddle. I am the Assistant Chief Engineer […]

The Media Pool

31 December, 1999 (14:00) | Projects, TV |

When I arrived to the KHBS/KHOG TV market in 1998 the tertiary station KHOG in Fayetteville was running its locally sold spots by manually breaking away from the programming they were receiving from KHBS. The Master Control Operator on duty would change a crosspoint on their router and then manually trigger a series of spots […]
