Intentional Interference on the NI4CE
As you may know, the NI4CE Repeater System has recently become the target of one
or more individuals who are interfering with the normal operation of the system.
These transmissions have included extended periods of kerchunking, DTMF tones
and audio not authorized for transmission under Part 97 rules. In all cases, the
person(s) responsible refuse to identify their station, also a violation of FCC
The target of these illegal transmissions has been the 443.450 repeater in
Holiday. The frequency of this activity has noticeably increased since the
146.64 repeater was removed from service earlier this month.
We want you to know this activity has been brought to the attention of the FCC
Field Office in Tampa. A case file has been opened by the Enforcement Division
at our request. At the same time, our technical crew has been collecting
recordings of these malicious transmissions and other data that will assist the
FCC with locating and prosecuting the individual(s) responsible for this abuse.
These illegal transmissions have made it increasingly difficult to monitor the
NI4CE system as well as use the system for legal two-way communications. Please
know if the end game for this individual(s) is a termination of service on
443.450 to the Amateur Radio community, it is not going to happen.
One last item….there has been a swirl of rumors predicting the imminent loss of
the Holiday site for the 443.450 repeater. We have had two lengthy discussions
with our host, Clear Channel Communications, Inc. They have indicated they have
no current plans to ask the West Central Florida Group, Inc, to turn off our
repeater and vacate the tower site.
