MODERATOR, PLEASE CLOSE/LOCK THIS THREAD, PLEASE!
Thanks, but I can tell you did not read all MY posts, I compared & eliminated the equip, long ago.
Being a past audiophile and having an Elec. Engineering degree & long interest in audio, methods of and equip., designing some stereo equipment even, & reading many research lit. on hearing and ppl's perceptions, I am not surprised with the responses here.
What's funny is the 'certainty'
of ppl's convictions, especially when they have ONLY 1 CBS station to sample
(I compared KOIN to at least 4 other CBS stations), no ability to compare but yet, they are so certain its my problem not KOIN's.
Strange, Funny, Sad, but not surprising with the casual/layperson's perceptions and certainty with so little foundation of experience or education, and not knowing how easily a humans senses/thoughts are fooled, good and bad.
The human brain really does some wonderful things, both hearing and seeing are SO very complex, human perceptions are fooled so very often (to the good often, ie mp3, mpeg2/4, etc) but you do not or may not perceive it unless you know the science, and maybe not even then.So I should have NEVER started this thread, but first thought it a 'Dish' signal issue, even though I heard it with DTV the previous summer, but had forgotten, my mistake in starting and maintaining this silly thread !!
I just wonder why it is ONLY KOIN that I hear this, oh forgot, KCBS (LA) did not have screechy audio either - 5 CBS stations!! Let this dead horse lay dead! Please! RIP dead horse!
This thread is quite long with a lot of back and forth, but did you DISCONNECT your sound system from the dish receiver and connect dish receiver audio output to the tv's audio input and listen to the sound through the TV speakers. If so, was the screechy sound still there?
If so and the sound is still there, it is your dish receiver. Do you have a second dish receiver in the house that has the screechy sound on the same channel?
It could even be the LNB on the Dish. I once had a customer that had one or two channels that would just blank out and not return until the next morning. Then that afternoon the same channel(s) would blank out again and and not return until the next day. Changed the LNB and that fixed the problem.
