Essentially, it seems there are new interference problems. The police and fire departments in some areas have been experiencing interference from - get ready for this - CELL PHONES! Yep, the huge numbers of cell phones and cell phone towers are beginning to make it difficult for the fire and police to communicate. Many folks with HTs that have been in reasonably close proximity to large communications centers (such as the 911 center about two miles from my house) already know about intermod. Hey, weren't cell phones supposed to be the new 'emergency' communications? Let's get this straight. First off, it's not new. It'e been around for over six years that I know of. The Comm Manager for Washington County (where I live) was the one who found the cause of the desensing and blew the whistle to APCO. Then other public safety victims came out of the woodwork, including several clients of the company that I consult for. Secondly, it's not "cell phones". It's Nextel, a hybrid technology system that emerged from Enhanced Specialized Mobile Repeaters (ESMRs) which were legalized for-profit entities to sell local repeater service to small or medium sized businesses on a multi-user basis. The only relationship that it has to real cell-phones is that it uses cellular digital technology and is used for "chatting" rather than dispatching. What happened was that when the 800 MHz band that was formerly TV Channels 80-88 was reassigned, part of it went to the (common carrier) cellphone service and the other part went to the land mobile services with alternate channels assigned to Industrial and to Public Safety licensees. The intent was for small businesses to establish small networks based on high elevation repeater sites carrying analog dispatch ("push-to-talk") communications, and the Public Sefety folks to establish trunked local dispatch systems at low-level sites. Enter the Merger and Acquisitions Masters. Nextel, guided by a maverick (who used to be at the FCC and screwed up his projects there) started buying up those ESMRs and erecting high powered cellular repeater sites at low elevations, most of which were close enough to Public Safety trunked system sites to cause front-end desensing from the full-time and full-channel digital voice systems that they migrated to. The sad thing is that the FCC is largely a shill for large business now. It would't take a ton of effort for some kind of coordination to help avoid this problem - but, hey, no regulation is better than regulation, right? APCO and Nextel worked out a solution which would mean moving licensees out of the interleaved pattern into homogenous blocks (like in the "good old days"), and worked out a financing plan, and it's now sitting at the Wireless Bureau "awaiting action" (a euphemism for gathering dust). -- 73 de K2ASP - Phil Kane From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon |

(Rush Limbaugh MODE ON)
Must be a liberal then..... wanting the government (yes the FCC is part of the government) to control your lives. A true republican/conservative wants limited/barebones government. (Rush Limbaugh MODE OFF) "Tony P." wrote in message ... In article , says... http://www.enemynation.com/ProductIm...ges/fcc300.gif Some of us hams might be proud to wear a shirt like that. While I don't disagree with Part 97 or the basic regulatory apparatus, I do disagree with the blatant censorship being perpetrated by the FCC. And I have both my Extra and my General Radiotelephone licenses. |

I'm happy to be registered Independent. And there are more of us all the time. P*****g people off because of actually thinking about an issue before voting! To date, it has been about a 60-40 split. The reader is encouraged to speculate which party has the 60, and which has the 40..... 8^) - Mike KB3EIA - Ryan KC8PMX "Mike Coslo" wrote in message ...

Not saying which one they should choose as I believe that is something they should educate themselves on, but not to vote the "big two" regardless.... Ryan KC8PMX |
