FCC grants WNRB improved non-critical-hours pattern
Today's FCC actions show that the FCC has approved
WNRB's new non-critical hours day pattern. This pattern,
which will be used from two hours after sunrise (worst
case is 9:15 AM in January) until two hours before
sunset (worst case is 2:15 PM in December) will
dramatically improve the station's signal to the
southwest during the middle of the day. The current
minimum is the equivalent of about 1 kW at about 231
degrees. This restriction is still necessary during
critical hours to protect Class A WLAC Nashville. The
new daytime minimum will be the equvalent of about 30 kW
over a broad arc (about 150 degrees centered on the
aforementioned 231 degrees). There will be a slight
decrease in daytime signal strength over Boston, but
nobody is likely to notice.
The change is not complex (a change in the power ratio
and phase of the the two towers used by day). The new
pattern, which ought to be in place rather soon, was
made possible by the deletion of what was once WNLC New
London CT, only about 75 miles from the WNRB TX. WNLC
operated with 10 kW-D/5 kW-N DA-2 using three towers
days and six towers nights. The site, New England's most
populous AM antenna farm, had a total of eight towers.
WNLC did a pretty good job of protecting WNRB at night,
but the day pattern primarily protected WLAC and
actually sent a very substantial signal toward WNRB.
Now, if somebody could only find something worthwhile to
do with the WNRB... How about this rumor (which I'm
starting right here, right now): ABC will buy WNRB and
flip Radio Disney from 1260 to 1510. Hibernia, which
owns WPZE, will then lease 1260 to Mrs Nash who will
move WILD to 1260 and will lease 1090 to some ethnic or
religious broadcaster.
