The Institute of Electrical and Electronics Engineers holds its annual Broadcast Symposium in San Antonio this week. And if I could be there, I’d be hitting up the last session of Thursday afternoon, for there may be a few fireworks.
There are two planned speakers: first up is David Layer, the Director of NAB Labs’ Radio Technology Committee, who will give a status report on the state of all-digital AM-HD signal testing. The most recent round concluded in Seattle, and depending on who you ask, the results were either spectacular or so-so. Continue reading “NAB v. DPR: Showdown in San Antonio?”

Digital PowerRadio Dispute: The Downside of Closed Systems
There’s been an interesting story playing itself out over the last month involving a company’s claims of discovering a way to dramatically improve reception of HD Radio signals.
Florida-based DigitalPower Radio announced in late March that it has developed a computational method that allows radio receivers a stronger lock on AM- and FM-HD signals, especially in areas where there might be analog-to-digital interference. Challenging conditions such as these have been detrimental to the robustness of HD signals more generally, for which the (FM) power increase implemented by some stations a couple of years ago only partially helped.
This improvement might be especially helpful in portable and mobile devices, as the change is made on a chip in the HD receiver, not on the transmission side. Continue reading “Digital PowerRadio Dispute: The Downside of Closed Systems”
