This may be a bit confusing but hopefully someone here can help. I have a coolsat 8100hd I use for my OTA HD channels and PVR recording it is great and to be able to record my real (not compressed) HD shows is a real plus! Now I have a bit of an issue and no one at Coolsat can answer this question. I have scanned all my OTA DTV channels and pick up all of the with the exception of channel 4 and 4.1 which to me makes no sense. I have plenty of signal and I can use the same antenna coax from my HDTV antenna and pick up channel 4 and 4.1 on my cheap $40.00 DTV-Analog converter box and my Sony 40" DTV. I have other TV's in the house with ATSC tuners wish all pick up channel 4 fine with signal levels of 85+ I have tried auto scans and manual scans and don't get it. From what I can see, the local channel is running on channel "10" digital but no where can I find a frequency chart that shows the frequencies that match the digital channels for OTA. In the Coolsat, there is a way to plug in a frequency and try to lock it in, but I need to know that frequency. My brother has an 8000hd, he is in Canada and watches tv from Buffalo.... he said he numbes he comes up with in the manual scan for channel is 623000 so, I try to plug that in and I get nothing. I"m a little fuzzy on this "Channel 10" pre June 12 vs after June 12 thing. this may all blow over on June 12th but I can not understand why I can get the channels on my Sony, Vizio and even my cheap radio shack converter box, but I can't lock in on the Coolsat... So, if anyone has any ideas suggestions, Frequencies I can enter manually in to the CS 8100hd I'd appreciate the help.. I"m just a bit frustraited I can't pull it in..
