Here's another example of just how bad IBOC is. I was staged at a monitoring point 11.5 miles NW of KCKK/1510 most of the day today while our consultant made adjustments to the 19 kw night DA pattern. I was at this particular location because it is on one of the nulls (328 degrees) that protects the 1510 station in Spokane WA. I was reading about 3 mV on the field intensity meter which should present a decent signal in the local area. While waiting I decided to check out the signal on my car radio. I was surprised to find the signal on 1510 completely covered by the IBOC hash from 1490 in Boulder. Boulder was 11 miles west of me so I was almost exactly between the two stations. Boulder is two channels away and runs only 1 kw ND. Yet it completely obliterated the 3 mV signal from 1510. I wish I could have shut off 1510 long enough to read the signal strength of the IBOC noise on that channel.
