Expect the rest of he jammers and scammers to turn off IBOC - they are all going under and can't even afford their electrical bills! Hope it's true. What do you think Eduardo? HD hardly uses any electrical. A sidelight on a tower uses more than most. Citadel turned of HD on a couple of AMs which were interfering at night, WABC an WJR. Eduardo -YDF - You can't have it both ways - Either the interference is a significant problem on AM or it's not. How come WBZ or KDKA or WHAM or WWVA keep their hd on full time? I'm within the protective contour of KDKA and WBZ interferes with them at night. To stations, the issue is not the protected contour but the groundwave useful coverage area and the dimensions of the Arbitron metro. WHAM and WWVA have no interference in their metros or areas immediately surrounding them. Neither do KDKA and WBZ. But apparently, WJR and WABC had problems in areas right at the edge of the metros, and decided it was not worth keeping the HD on at night. Since night radio listening is only a tiny part of day listening, the decision is relatively simple. Eduardo - You really don't know what your talking about. WBZ is a times as strong or stronger than KDKA's groundwave in their local area. This is not debatable. WBZ hash can be heard under KDKA most nights. Why either of them is transmitting it is a mystery to me. The only thing I can figure is they've bought into the idiotic notion that people will eventually come if they keep pushing it. This was a decision based on wishful marketing and foolish station owner/ operators not interference - of which there is plenty. Eduardo - IBOC / HD radio is all about recklessly trying to making money with no regard for any other issue, be that interference, consumer wants or needs, smaller broadcaster coverage areas, or anything else you can think of. You mistakenly think there was actual thought that goes into who transmits it and who doesn't - as if there is some "big-picture" plan. There is not. Its all about economics and the possibility of making big $$. Greed and nothing else. A wiser Goverment would have never allowed it. But that we no longer have. |

You are saying that WBZ is stronger (I assume you mean "at night") in Allegheny, Beaver, Butler, Fayette, Washington and Westmoreland counties of Pennsylvania than KDKA? Those 6 counties are the only market area that KDKA is interested in. Similarly, I doubt that KDKA interferes with WBZ in Essex, Middlesex, Norfolk, Plymouth, Suffolk, Worcester and Hillsborough counties, the Boston MSA or, as you say, "market area." Since WBZ is directional westward, it's not likely they will have any interference of significance. Heck, every AM gets occasional interference; I recall numerous times hearing Venezuela on 1-A Clear Channel 1100 in early evenings over WKYC (now WTAM) even though I was about 12 miles from the WTAM transmitter. That's one of the reasons AM has so little appeal to the generations that grew up on FM... interference, noise, static, lousy audio quality. |

The insertion loss depends on the combiner system. In cases of FM, using separate antennae, there is no insertion loss. It's still a small amount, any way you look at it. Tower obstruction lighting or AC consumption is much more. |

But the overall cost to a station is a tiny fraction of a percent of its operating budget. Same goes for equipment. If the cost is significant, 1) the station can not and won't be able to compete with better financed stations and, 2) the station should not consider HD. HD is for significant players in significant markets. |

HD hardly uses any electrical. A sidelight on a tower uses more than most.. Citadel turned of HD on a couple of AMs which were interfering at night, WABC an WJR. "Upping HD Radio signal strengths" "The short math given what we know today is that it will cost roughly double on the transmission end to increase HD Radio FM power tenfold. There are likely to be additional costs for cooling and air handling as well, in order to dissipate the excess energy required to get out another 10 dB in HD Radio signal. And, for some higher powered stations, existing HD Radio configurations may not be able to handle the power load, which could add to the cost and complexity of increasing HD Radio beyond its current power level... Also worth considering is existing transmitter combiner technology and whether or not it can support the added demands of increasing HD Radio broadcasts another 10 dB. If not, then it’s very likely that stations at the higher power levels will need to factor in a new antenna system that can support HD Radio, rather than piggyback onto their existing FM antenna system. At the higher powers, especially, an immediate 10 dB increase in HD Radio signal may be cost prohibitive... This will typically mean the addition of another similarly rated transmitter (using a combining technique) or the purchase of a new transmitter of roughly twice today’s power level." http://tinyurl.com/cfbrtq |
