Some days I am having some NOAA interference every few minutes for about 1.5 seconds on my CSX feed. The frequency it happens on is 160.470 AAR24. The nearest NOAA tower to me is about 9 miles away, 1000W, and 500ft.... It's frequency is 162.475. The easiest solution is to lock out the affected channel, but I don't want to lose that channel because it is a local shortline railroad. The setup I have is a Diamond CP22e at 25ft tuned to 161mhz, LMR400 feedline about 30 feet long, (radio is upstairs) ARR P160VDG preamplifier, Kenwood TM281A. How can I most efficiently get rid of this?
