Whats up with these RTV channels on 87 and 137? I used to get all those, then for awhile I could get some on 87 at 4000mhz, and all of them on 137. Tonight I can't get anything but a bunch of blank channels. Are they gone, or is the old reliable Vantage barfed? Just scanned in about 60blank channels of S2 blackness on 87-ONE channel works but it is a weird looking thing with guys wearing headphones and what looks like twitter messages on the screen. It shows 4024mhz, something like 2034Sr. On 137 I get 33 channels of nothingness. This receiver does H264 channels, but not these!
