Just an update. I think something was changed with the Mitchell Corners Tower. The signal does seem weaker then it used to be. As I travel west bound on the 401, I loose it at Whitby-Ajax and then get the Uxbridge 104 tower, when I usually have it till Port Union and then right into the CN Tower.
At anytime, if I reprogram the GO Transit system on the 396T, I will not get them at all till I hit any tower other than Mitchell Corners. As soon as hit the Uxbridge or the CN tower, they start coming in and afterwords Mitchell Corners works. I can update or reprgram any other system, as long as I leave GO transit alone, it is fine. Soon as I make a change on the system, I loose them till I hit other tower.
Very strange.. It does also seem that the Mitchell Corners tower does have a higher error rates too. not much, but a bit higer then the other towers.
