It was never a problem when WCVB-DT was operating a few hours a day, but earlier this year, when the tower work on the Needham tower WCVB shares with WBZ-TV/DT and WGBH/WGBX was completed and WCVB-DT was able to go full-time at full power, officers down in South Jersey started to notice interference to their two-way radio system, which they tracked down to the new DTV signal more than 250 miles to the northeast.
Last week the dispute hit the media, with Ocean County (even closer to the coast than Camden County) joining in a complaint to the FCC about interference to their radio systems, which operate in the "T-Band," first allocated a couple of decades ago on what were then largely unused channels 14-20 in the UHF-TV spectrum. (How unused? So much so that several low UHF TV allocations, such as 14 in Worcester, 16 in Providence and 18 in New Brunswick, N.J., were deleted and reassigned for public safety use.)

DTV, of course, changed all that, with every scrap of the UHF TV spectrum being pressed into use during the lengthy transition from analog to digital. In Boston, it's not just 20; channel 19 is in use by WGBH-DT and channel 18 is allocated for WMFP-DT; other T-Band DTVs in the Northeast are shown in the table at right.
In other words, the spectrum that T-band users have had pretty much to themselves is about to get full, and it doesn't appear that the FCC did its homework when making the allocations there, or in other parts of the DTV spectrum. (Just ask WHRO-DT Norfolk VA and WBOC-TV Salisbury MD, which are battling over channel 16, or WOOD-TV Grand Rapids MI and WMVS-DT Milwaukee, which are fighting over channel 8.)
The culprit appears to be the FCC's modeling mechanism, which does not fully account for the effects of unusual propagation, especially over water. (Notice a common thread in all these DTV disputes?)
Any DXer knows that there's nothing completely predictable about propagation at almost any frequency below 800 MHz (as we type this, we're watching an E-skip pileup on channel 3 that's bringing in stations from Memphis, Springfield MO, Harrisburg IL and Eufaula OK, perfectly normal behavior in mid-July but quite unusual in early November), and every reason to think that a 500 MHz signal with a megawatt of power from Boston will often ride the tropospheric ducts down to New Jersey in the summertime. But those are the sort of questions that should have been asked before a license was issued, not after millions of dollars were spent to put up a licensed signal on channel 20 in Boston.
How will this all get resolved now that the damage has been done? The good news is that there's no reason to expect WCVB-DT to remain on channel 20 forever; when the DTV transition is complete, the digital signal will likely replace WCVB's analog on channel 5. You can read more thoughts on digital transitioning down at the bottom of this week's column. In the meantime, we'll be following this closely to see how the FCC gets itself out of the hole it's dug.
Congratulations to Mistress Carrie of WAAF (107.3 Worcester), who adds "music director" to her midday jock duties at the hard rocker.
And congratulations to WJUL (91.5 Lowell), which marked its 50th anniversary (it started as carrier-current WLTI in January 1953 and has been on FM since 1968) with a reunion this past Saturday. We'll try to bring you some pictures and stories in our next issue....
We've been remiss in mentioning the latest addition to the schedule at Sporting News Radio's WWZN (1510 Boston); Mike Adams has joined the station to do mornings, which means that 1510 is now running local all day long before joining Sporting News in the evenings (when there's not a Celtics game, anyway.)
More TV news: WCEA-LP, displaced from channel 19 by WGBH-DT, has lost its bid to move to channel 3, with the FCC dismissing its application for that low frequency after receiving petitions to deny (we'd guess from WBZ, WGBH and WFSB, perhaps?) WCEA-LP now has a new application in to move to channel 58 with 5 kW visual, but that channel will also have to change in a few years when the FCC removes channels 52-69 from TV service.
Out west, W51AE (Channel 51) atop Mount Greylock has applied to move to channel 38; the translator for Albany's WNYT is being displaced by the new full-power CP for Pittsfield on channel 51.
And Springfield's WSPR (1270) has been granted a move to the site of co-owned WACM (1490 West Springfield); it'll run 5 kW day, 1 kW night from the existing WACM tower and a new second tower to be built nearby.
Speaking of sports in Rhode Island, the Celtics are back on the Providence dial, with WSKO (790) and WSKO-FM (99.7 Wakefield-Peace Dale) picking them up after a season's absence down there.
Down the coast, Scott Weimer will take over as PD of Cox classic rocker WEFX (95.9 Norwalk) Nov. 18; he comes to the market after stints at the Worldspace and XM satellite radio services.
Four Times Square, the "Condé Nast Building" on Broadway between 41st and 42nd streets, is already home to auxiliary FM transmitters for New York's Clear Channel and Spanish Broadcasting System clusters, as well as public radio WNYC-FM (93.9).
Now the building's owner, The Durst Organization, plans to add another 200 or so feet to the mast atop 4 Times Square to provide auxiliary transmitter space for New York's TV stations.
(By the way, Durst has hired one of the city's top broadcast engineers to supervise its own broadcast-leasing operations: John Lyons, the former chief engineer for Clear Channel's WAXQ in New York, now calls Four Times Square home, which is only fitting, considering he had a huge hand in designing the broadcast facility there!)
Meanwhile, the Metropolitan TV Alliance, the industry group formed in the wake of the Sept. 11 attacks to restore full TV service, is still pressing ahead on its own plans for a 2000-foot tower somewhere on the Jersey side of the Hudson for TV transmission; if both that plan and the Durst plan at 4 Times Square work out, New York's TV stations will have much more redundancy in their transmission systems than they've ever had before, which is a good thing.
More New York aux news: the Emmis stations, WQHT (97.1), WRKS (98.7) and WQCD (101.9), have been granted auxiliary facilities up on First Mountain in West Orange, N.J., running 29.5 kW from one of the towers at the WFME (94.7) site.
