Though not the 10 dB increase that’s currently requested at the Commission, but 6 dB – for now. The technology developer submits testing it did in Boston with Greater Media stations like AC WMJX (106.7), and says it “demonstrates the 6dB increase in power provides FM broadcasters with a significant improvement in coverage.“ But chances are the Commission will withhold approval until it sees the results of a second set of field tests conducted by National Public Radio. The first group, conducted around Pittsburgh, showed the potential for interference if a 10 dB hike were allowed. HD Radio operators say the current power levels are insufficient to give many potential set-buyers a good signal, even in the retail store.
