It flashes once I stop transmitting (even at 0.1watt output, 0.0w output, or in TEST mode)..........and continues to flash forever.(in receive)

The NB only works in receive. Try the various settings. If the particular fence controller has a long rise time, the NB will not fire on it. NR may work, but for me, I don't like to use it because it distorts the signal. Noise reduction looks for what it "thinks is a coorelated signal and builds a filter around it. It takes a bit of time to build that filter. It works better on CW than it does on SSB IMHO. 73, Don W3FPR On 5/15/2016 6:01 PM, Mike Smith VE9AA wrote: > Don, > > Thanks.
