The man told me they have a crystal for 89.9 in a reciever there in the tower. Can they only get what they have crystals for or is *any* station on FM radio available over the cable (as far as improving its reception is concerned, etc?) PAT]Apparently, CableOne uses "individually-processed" cable FM ratherthan "allband FM," so they have a separate FM processor for eachstation. They can only get what they have processors for.See and scroll down to THE RISE OF CABLEFM. The so-called "crystal" the man told you about is the FMprocessor. Although different manufacturers use different circuitry,the processor probably includes two crystal-controlled localoscillators (XCLO). Assuming that the output frequency equals theinput frequency, one of the XCLOs (probably the output) isphase-locked to the other.Input ----> Mixer ----> IF ----> Mixer ----> OutputFilter ^ strip ^ Filter| |XCLO - - - - - - - - XCLONeal McLainnmclain@annsgarden.com[TELECOM Digest Editor's Note: Thanks for that explanation. I knowthat *prior to* CableOne moving into town we had Time Warner as ourcable provider here. Being as we are, 100 miles southeast of Wichita,about 120 miles straight south of Topeka, 80 miles north of Tulsa, OKand 90 miles west of Pittsburg, KS/Joplin, MO (all cities with somesemblance of television stations and radio signals) we had very littlehere other than our own KIND (1010 AM/102.7 FM) and Coffeyville's KGGFat 690 AM and their FM station to listen to. In other words, *vast*amounts of open space on the FM band. Then Time Warner moved into townand brought us 60 cable television channels, although Cox took over(and still maintains) Coffeyville. Many of the cable channelsduplicated each other (in other words, the CBS affiliate on Wichitaand the CBS affiliate in Topeka many times of day had the sameprograms on), but it was better than nothing.City of Independence insisted on, and received three or four of thosechannels for community use; i.e. a channel each for Independence HighSchool, the City Hall channel for council meetings, and a channel forthe college, plus a community service channel (channel 10). TimeWarner spread out their offerings on the rest of the cable: all threemajor networks at least once or twice, Fox got a channel (cablechannel three from the Fox affiliate in Tulsa, but *not* the Foxaffiliate in Joplin, MO [although CBS/NBC/ABC each appear twice, onceeach from variously Tulsa, Joplin, Topeka, Wichita]) and a few otherchannels, including the 'Shopping' thing that seems to go on all thetime, the idiots on the 'Christian' channel, Eternal Word Television channel, and a few movie channels,Disney, cartoons, and whatnot. As I said, better than nothing, andbetter than the very tall antennas some people had on their houses orin the back yard in order to get *TWO* snowy, grainy channels. Then afew years ago, some outfit moved in town with an FM radio stationlicensed to Dearing, Kansas (wide spot in the road south of us withpopulation about 250 people) but studios in Coffeyville. Very loud,very raucus acid rock around the clock, 98.5 FM I think. All the kidslove it; I hate it.Then Time Warner decided to sell their 'property' here, in the form ofa trade off with Cable One. Time Warner got some town they likedbetter and Cable One got us. Same office on Penn Street downtown, samepeople working there, same techs, etc. I was walking around downtownone day and they were painting over the Time Warner sign outside witha new sign saying Cable One. And the lady who works in the officethere told me "We will become Cable One as soon as the city councilhas their meeting tomorrow and gives us that franchise instead. TimeWarner is on the way out." The Reporter newspaper the next day saidthat city council had issued a franchise to Cable One of
