I have a 6 meter repeater operating Portland Oregon on 53.29 MHz with an input of 51.59 Mhz. A few years ago we started receiving noise on our input, and traced it down to the new Larkin solid-state transmitter that the local TV channel 2 had recently installed. With their old RCA tube transmitter, they had a much cleaner signal. Looking the the proof of performance tests between the two transmitters, the old RCA transmitter was about 20 DB cleaner in the amateur 6 meter band. My repeater is located less than a 1/2 mile from their transmitter. No amount of filtering on my end has been able to fix the problem.
I've had it. I am DEMANDING that the local TV channel 2 STOP transmitting or change to a different frequency to end the interference they are causing my 6 meter repeater. I am giving them 6 weeks notice to either stop transmitting or change frequency, and I have picked a deadline of February 18, 2009 or I will initiate further action.
