Anyone else hear a grungy/screechy KOIN sound (via 5.1 system)? I travel around & receive several local feeds from Dish (DTV until last yr), The audio on KOIN/CMS sounds very grungy & sibilant, the center channel dialog (much of what we listen to) on my decent 5.1 system, is just awful, very strident, screechy voices (most importantly) but other mid-range sounds are screechy as well. (sounds over-modulated if you know what that means) Human voices do NOT sound like that, no 'real' audio sounds like this! (can not compare via antenna, no signal here) The Eugene, Or, the Sacramento,Calif & San Francisco CBS stations do NOT sound like this! (same sound system, Dish recvr, etc) I actually 'reluctantly' watch KOIN/CBS for this reason, but like some shows. I have contacted the KOIN engineering & they say their feed is the same to both Dish & DTV (makes sense since I heard the same bad audio from both), I then suggested it imply's a 'source' problem, ie - under their control, or something they are doing. He claims they 'do not alter' the CBS feed, but yet I do not hear this from the other CBS stations. The engineer says he is due to get Dish soon, personally, so will check it out himself (he is in charge of the transmission & translators). PS: No other channel sounds this bad, some sound quite nice!
