Speaking of the DTV conversion, I saw an announcement on NHPTV last
night that they would be reducing power on WENH-TV for the conversion.
Presumably this is one of those deals where they split a combined
analog transmitter, and convert one half to digital.
Hmmm... their form 387 says it's a bit more complicated than that:
AT THE END OF THE TRANSITION WE WILL MOVE FROM OUR TEMPORARY
OUT-OF-CORE UHF CHANNEL TO OUR ANALOG CHANNEL 11 FOR PERMANENT
DTV OPERATIONS. WE HOLD A MAXIMIZED CONSTRUCTION PERMIT,
GRANTED ON JULY 16, 2008, FOR DIGITAL CHANNEL 11. THAT PERMIT
MODIFIED OUR ORIGINAL PERMIT TO INCREASE POWER FROM 15.8 KW
ERP TO 30 KW ERP AND CHANGE FROM A NONDIRECTIONAL TO A
DIRECTIONAL ANTENNA. WE WILL NEED TO FILE FOR EXTENSION OF
THAT PERMIT. WE TOOK DELIVERY OF THE NEW TRANSMITTER ON
SEPTEMBER 22, 2008. WE HAVE BEEN WORKING WITH UNIVERSITY
PROCUREMENT OFFICIALS THROUGH THE COMPLEX BIDDING PROCESS
REQUIRED FOR ACQUISITION OF THE NEW DIRECTIONAL ANTENNA. WE
PLAN TO COMPLETE THAT PROCESS AND PLACE AN ORDER BY FEBRUARY
1, 2009 AND, BASED ON CURRENT MANUFACTURERS ESTIMATES, TO TAKE
DELIVERY BY APPROXIMATELY JULY 6, 2009. THE ANTENNA SITE IS ON
A MOUNTAINTOP WHERE HIGH WINDS DO NOT NORMALLY SUBSIDE UNTIL
THE SUMMER, SO JULY WOULD BE A FAVORABLE TIME FOR THE
INSTALLATION PROJECT. EFFECTIVE NOVEMBER 18, 2008 WE WILL
REDUCE ANALOG POWER TO 50% IN ORDER TO BEGIN THE INSTALLATION
OF THE NEW DTV TRANSMITTER AND WILL REMAIN AT 50% POWER UNTIL
THE TRANSITION DEADLINE. THE ANALOG POWER REDUCTION IS
NECESSARY BECAUSE WE WILL BE REMOVING ONE ANALOG AMPLIFIER
CABINET FROM THE TRANSMITTER IN ORDER TO INSTALL A DTV
AMPLIFIER CABINET. WE HAVE THEREFORE REQUESTED SPECIAL
TEMPORARY AUTHORITY TO OPERATE AT 50% OF AUTHORIZED ERP AS OF
THE TRANSITION DATE. NOVEMBER 18 IS THE LATEST DATE FOR
INSTALLATION THAT COULD BE SCHEDULED BY THE TRANSMITTER
MANUFACTURER. ON FEBRUARY 17, 2009 WE WILL SHUT DOWN THE
ANALOG TRANSMITTER, CONNECT THE DTV TRANSMITTER OUTPUT TO THE
ANTENNA FEEDLINE, AND PUT THE CHANNEL 11 DTV FACILITIES ON
LINE. WE WILL CONCURRENTLY SHUT DOWN THE OUT-OF-CORE CHANNEL
57 TRANSMITTER. THE INITIAL ACTIVATION OF DTV CHANNEL 11 WILL
BE AT THE POWER LEVEL SPECIFIED IN OUR PREVIOUS CONSTRUCTION
PERMIT, 15.8 KW, BECAUSE THE DIRECTIONAL ANTENNA IS NEEDED TO
BROADCAST AT THE POWER SPECIFIED IN THE MAXIMIZED CONSTRUCTION
PERMIT. A REQUEST FOR STA TO SUPPORT OPERATION AT 15.8KW WILL
BE FILED.
They have filed to maximize the other two stations (WLED-TV and
WEKW-TV) but will not do so prior to the transition.
