Today the Northern California GMRS Users Group (NCGUG) reached a two-year milestone. Since July 2016, we have filed 84 specific complaints of ongoing and repeated interference related to unlicensed maritime traffic on our repeater uplink channel (affecting two repeaters). We have yet to receive anything significant from Commission other than their canned response, but we did receive some meaningful help from the local enforcement office. As a result, we were able to ID one of the shipping companies involved and reach out to them. Of course, this is truly a whack-a-mole situation as it is an international shipping problem. However, we noted that the local enforcement office is not tied into this system at all and were unaware of any complaints. We had to notify them directly. Obviously some improvements are needed here....but this allows DC to filter this stuff for them. But this information may be critical someday in defending the GMRS and our interests. I particularly encourage repeater owners to monitor their input frequencies for problems when possible as these are the most critical asset of a GMRS repeater system.
