Thread: About 37xx converted to 34xx satellites reception accuracy

Ok, i'm understanding most of that, but i wouldn't have thought that DOP was a problem given the spread of the sats in the pics. The triangulation should be quite good from the spread shown, and in fact that spread was similarly maintained though the entire test run described in Post #29.

So, why does 34x0 convert suffer from accuracy problem especially when moving? If we discount WAAS, DOP, signal strength.. what's left? Fw somewhat incompatible with the 37x0 gps hw on these converted units? Dasivarsa's genuine 3490 gets consistent 3m reading same as my original 3790 (I still think that's not realistic btw, if there is no meaningful WAAS correction how can that accuracy precision be maintained by a 'non-professional' basic gps receiver?).

So Giomen, how about you or Loly or someone please mod 34x0 v7.6 fw with 37x0 gps fw from wotever region it's in, post an *.rgn file and i and any other intrepid souls will flash it to our 34xx converts? Pretty please??

EDIT: Made a reply to the first part of your post also, but a rare flash of good taste and sense led me to decide to delete it after a few hours. However, first i copied it [Only registered and activated users can see links. ] in Aussie Gems if you wanna have a look (you can even reply to it there if you're game!).
