It does not appear that US radio amateurs will gain a new
band at 70 MHz anytime soon. The FCC has denied a Petition for Rule Making
filed earlier this year by Glen E. Zook, K9STH, of Richardson, Texas, seeking
to add a 4 meter band to Amateur Radio’s inventory of VHF allocations. Zook had
floated the proposal in 2010, and his petition was dated January 27, 2010, but
the FCC said it did not receive it until last May. Zook asked the Commission to
allocate 70.0 to 70.5 MHz to Amateur Radio because, Zook’s Petition asserted,
“the recent migration of broadcast television stations to primarily UHF
frequencies basically eliminates any probable interference to television
channels 4 or 5.” VHF TV channel 4 occupies 66 to 72 MHz.
“Because the Zook Petition is based on a faulty premise —
that broadcasting use within the 70.0-70.5 MHz band will diminish or cease —
its argument that amateur band users could operate without causing harmful
interference to any existing service lacks sufficient support to warrant our
further consideration, The FCC said in a September 17 Order denying the
Petition.
The FCC pointed out that three full-power TV stations,
110 low-power TV stations and translators, and six Class A TV station now
occupy channel 4 in the US. In addition, the Commission, through an “ongoing
incentive auction proceeding,” is attempting to “repurpose” a portion of
television broadcast spectrum for broadband operations and “repack the
remaining TV stations into a smaller frequency range.” Under certain scenarios,
the FCC said, channel 4 could become even more heavily populated by broadcast
users in the future.
“Given the complexity of the of the incentive auction
proceeding, we also conclude that it would not serve the public interest to
further complicate that unique undertaking by proposing to introduce a new
service into the broadcasting frequencies at this time,” the FCC said. The
Order noted that fixed and mobile services will continue to operate in the
frequencies between channels 4 and 5 (76 to 82 MHz).
As Zook noted in his petition, a 4 meter band has been
authorized for Amateur Radio use in the UK and in a number of other European
and African countries. The FCC said that since it wasn’t planning to grant
Zook’s petition, it declined to evaluate his claims “regarding the benefits
that amateurs would derive from use of the band.” Zook’s original proposal
asked to have the FCC open up the allocation to all classes of Amateur Radio
licensees.
Brian Justin, WA1ZMS, operated an Experimental Service
beacon transmitter from Virginia on 70.005 MHz under the call sign WE9XFT. At
the time his Experimental license was granted in 2010, Justin told the ARRL
that he was not seeking to have the FCC create a 4 meter band. “This beacon is
purely for radio science for use as an E-skip detection device,” he explained.
