Rene' Here are my two cents worth. To me (so far) the sky is not falling, but....if the dial gets loaded with wall to wall HD, then the situation is different. The sky is indeed falling. Even though the center carrier channel of IBOC may not fall on adjacents directly, but the splatter from the IBOC hash sure does. Plus splits are a different thing at 9 khz spacing. You can narrow the bandwidth and use upper and lower sideband all you want on the stronger IBOCer and you still get hiss. Maybe not enough to totally wipe out the adjacents, but enough to wipe out any weak signal that might be there. The only way I have found to get rid of the majority of the hiss is by phasing and that only works most of the time as the skip signal is there to make it hard to get a stable enough signal to get a total null of it. and then it constantly changes. On gw it is a different story. Also one other issue regarding phasing is often in phasing the noise you also end up phasing out the weak signal you are trying to hear. Like in the case of TPs and DUs. Often they are weak to begin with and you add all of the hiss then the signal is covered up. A lot is depentant on how many IBOCers we get. If it stayed about the same as now, I could live with it. But I doubt it will. I already hear of two more IBOCers added for OR in the next couple of weeks. In my boat, there are only two ways out of this, either IBOC goes or the DXer moves. That is if they want to continue DXing MW. Another option is to move to another band. Time will tell where this all goes. As one very active serious DXer that goes for flea power signals, IBOC is not good. Rene' just think about the weak signals I heard from your two tests. If IBOC would have been on those frequencies, I doubt I would have heard them. Those two Philly stations are some of my best, especially the WFIL.
