I'm puzzled as to why 3 kHz isn't good enough. I can't say that I've heard any TIS stations which were functioning properly which were difficult to hear. I'd guess this might be an economic issue relating to the added costs of filtering, in which case a change to 5 kHz won't change anything.

The NAB instead would like to see a compromise of 5 KHz, which allows for better audio clarity, but still provides some interference protection to full power stations.
