The plot thickens.
So I left Eastport at about 7:00am on Thursday, August 23rd with my Raymarine e125 and go to Mystic, CT. No problems with the GPS at all (I had left my backup Garmin off for that trip). From there went to Newport, had both GPS on, again no problems.
Yesterday I came back from Newport and again came back along the Quogue canal. First my Garmin loses signal east of Westhampton, sometimes able to require after a while, but always losing signal again, same as before.
But as I approached the Beach lane bridge my new GPS starts losing a fix, but reacquires almost immediately. Does this a number of times as I proceed West. The Garmin doing roughly the same, just not requiring nearly as quickly. Around Easport at the end of my trip my Raymarine would not reaquire.
I have no idea why 3 different GPS would have problems in this area. The 125 seems to cope the best, requiring a fix quickly, but even that unit was affected. I also find it odd I did not have a problem early in the morning on Thursday, but did on the afternoon on Friday. It really does feel like an interference problem but I have no idea what could cause an issue over so wide an area.
