It's time to drop radio's protections for TV Channel 6 and re-purpose
that spectrum to the FM band. So says engineering consultant John Mullaney.
In an FCC filing, Mullaney says adding 82 to 88 MHz to the bottom of the
FM band would ease overcrowding; the time is also right for the agency to
decide if TV Channel 5 should be reallocated to radio as well, he said.
"The assumptions that Channels 2-6 are technically equal to the remaining
Channels 7-51 has proved not to be totally accurate," says Mullaney in the
filing.
"We believe the problems associated with impulse noise and greater
difficulty in compensating for signal cancellations are some of the major
reasons why there are only 38 potential [TV] digital allotments under
consideration while there are currently 302 analog full-service analog
allotments."
Because only eight digital allotments are proposed for TV Channel 6,
Mullaney believes, based upon this "extreme underutilization of TV 6, the
commission could also consider a shared use of the channel but limit the
sharing to just those full-service digital TV allotments currently under
consideration."
Many of the recently filed NCE applications for radio allocations either
ignored Channel 6 protection or curtailed their proposed power levels to
protect those analog channels, he said.
The thousands of applications filed in the recent window, as well as more
than 14,000 applications filed in the 2003 FM translator window, demonstrates
pent-up-demand for FM spectrum, he argues.
One allocation for a TV channel could be used for up to 30 FM radio
stations; such additions could go a long way towards easing short-spacing
conditions on the FM band, he states.
