IBOC Night 3... What a difference two nights (and changing propagation) make. I think the impact of IBOC is driven home by seeing its effect on the RF spectrum. Take a look at the image of the the range of 700 - 860 kHz of spectrum I saved on Thursday night on my SDR-IQ, and compare it to the one from tonight:
http://dx-nexus.blogspot.com/ On the pictures shown, the bright white bands are the IBOC signals.Thebrighter the band, the more intense the signal. On Thursday the only stations audible with IBOC in this range were WLW and WOR. Tonight as I listen, there are 8-10 channels *in this range alone* that are totally covered by the IBOC noise from at least 5 stations, by my count. The IBOC traces fade in and out as the propagation changes and sometimes there is less of an effect, sometimes more. To me, this says those who predicted wholesale trashing of the AM band by IBOC were closer to being correct than those who predicted lesser impact. I've been saving bandscans on the SDR-IQ for the past few months, so I'll have plenty of "before IBOC" to compare with the "after IBOC" situation.
