And not just to adjacent stations – iBiquity’s proposed 10-fold power hike for FM digital sidebands will cause what one commentator has called “honkin’ interference” to an HD parent station’s analog signal. Although the suspicions of just what increasing the signal strength of FM-HD sidebands would do to analog FM radio coverage have been well-discussed in the engineering community for nine months now, the new report from NPR Labs confirms the worst.
The “monumental 18-month study,” involving extensive laboratory and field-testing of increased FM-HD sideband power finds that increased digital interference is simply unavoidable. While the tests do show that increasing FM-HD sideband power by a factor of 10 will make digital service coverage equivalent to (or, in some cases, slightly exceed) the coverage of a station’s analog signal, the modification comes at a price: Continue reading “Raising FM-HD Power Levels Will Cause Increased Interference”

Post-Facto Piracy: Not So Bad
I just updated the Enforcement Action Database: FCC field agents really went on a tear in July, and they are on pace to meet or beat their enforcement record set just last year.
But the really interesting cases I found involved stations who were licensed, let them lapse, and then just kept running as if nothing was amiss. Continue reading “Post-Facto Piracy: Not So Bad”
FCC Agents Illegally Impersonate Real Cops
This is a first, as far as I know. The FCC’s tried to bluff their way into busts in the past, but not past actual cops.
In June, FCC Enforcement Bureau field agents made a run into Mount Carmel, Tennessee, to investigate unauthorized jamming of a police radio channel in the area (the problem had been going on for months before the FCC got around to sniffing around).
While in town, the agents ran into Mount Carmel and Church Hill police officers not once, but twice, on traffic stops. In both instances, the FCC folks told the local cops that they were part of the Tennessee Bureau of Investigation Meth Task Force. They had no credentials to back up their claim, and that made the cops suspicious. Continue reading “FCC Agents Illegally Impersonate Real Cops”
Translator-Mongers and AM Stations Eye Expanded FM Band
Two suspicious proposals to expand the FM spectrum have surfaced at the FCC. While on its face the idea seems promising, the devil, as always, is in the details.
The first proposal was filed in late July by the Educational Media Foundation – parent company of the K-LOVE and AIR-1 Christian music radio networks, which can already be heard on more than 150 full-power, low-power, and FM translator stations.
A second, new group, called the “Broadcast Maximization Committee,” which represents the interests of AM broadcasters, followed up with its own proposal within days of EMF’s filing. It is difficult to believe the timing of the filings were coincidental. Continue reading “Translator-Mongers and AM Stations Eye Expanded FM Band”
LPFM: Movement in Congress?
It appears that the U.S. Senate may be moving toward a floor vote on the Local Community Radio Act. This bill originally began under the auspices of undoing the Congressional fiat in 2001 which severely restricted the promulgation of new low-power FM (LPFM) radio stations. By imposing draconian channel-spacing regulations on the new service, LPFM stations were precluded from being sited in areas of the nation in which 80% of the population lives.
The Local Community Radio Act has been the focus of a seven-year campaign to right this wrong. Most importantly, it would relax channel-spacing rules for LPFM stations (allowing them to be placed in more urban areas) and give LPFM stations a semblance of parity with regard to other classes of FM station. This would make LPFMs less susceptible to being bumped off the air by a larger station looking to move or otherwise modify its own transmission infrastructure.

Digital Radio Mondiale Tests Underway in Alaska
According to my pal Bennett Kobb, limited tests of the DRM broadcast protocol are now taking place on a station in Alaska specifically licensed for the research. It is important to note, however, that the tests do not involve the broadcast bands – although Digital Radio Mondiale has been certified to work on them all.
Instead, the ultimate hope of these DRM tests is to assess the protocol’s performance in the 26 MHz segment of the spectrum. This falls between frequencies designated for radio astronomy and maritime mobile use – and, according to the experiment’s proponents, could be utilized to provide “hundreds” of new, low-power community-based broadcasting stations across the country.

Sirius/XM Merger Sidebar
As lobbying over the conditions of the merger between the Sirius and XM satellite radio networks entered the home stretch, iBiquity Corporation and the National Association of Broadcasters requested that the Federal Communications Commission mandate all future satellite radio receivers to be interoperable with terrestrial digital AM and FM broadcasts.
This was a move by HD Radio‘s proponents to try and get something for nothing. XM and Sirius both subsidized the adoption of satellite radio receivers, especially in vehicles, by making the reception technology freely available and offering special deals to new subscribers (such as free service for a year or more, especially for folks who bought new cars and trucks with a satellite radio receiver as an option). In contrast, iBiquity Corporation wants those who make and market HD radio to pay it a cut from every HD receiver sold – effectively asking auto companies to partially pay the way for HD’s adoption. This is a proposal that nearly all have resisted. Continue reading “Sirius/XM Merger Sidebar”
XM/Sirius Merger Hinged on Piracy Compliance
After a week-long, non-transparent deliberation, the Federal Communications Commission has reportedly signed off on the merger of the XM and Sirius satellite radio networks.
Many of the tea leaf-readers did not correctly forecast the outcome: most expected at least one Democratic Commissioner, Jonathan Adelstein, would vote for the merger, provided there were certain public interest obligations on the new, singular satellite broadcast entity. These would have included requirements such as a percentage of total satellite radio capacity be devoted to non-commercial, possibly public-access channels, and that the new company provide tiers of service that do not gouge existing and future subscribers. Some of these conditions will apply to the merged company, but the Commissioners’ votes themselves ultimately split along party lines. Continue reading “XM/Sirius Merger Hinged on Piracy Compliance”
Truthful Translations Almost Go Mainstream
No, not the massive archive curated here: this boost is courtesy of Stephen Colbert’s “Make [John] McCain Exciting Challenge.” The Colbert Report uploaded footage of McCain standing behind a green screen, and then asked the public to make his speechifying more attention-grabbing through the magic of digital video editing technology.

Miscellaneous Follow-Upage
After months of frustration, the hosting provider for DIYmedia.net has saved my day by stepping in and graciously providing me with independent, unrestricted e-mail capability. I’ll never have to rely on Comcast again for that application (provided Comcast’s general broadband network uptime remains reliable, which is a questionable proposition).
You know you’ve got a systemic problem when the first prompt a customer encounters at your 1-800 number is, “For trouble with your service….” Continue reading “Miscellaneous Follow-Upage”
