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

Nor was I aware of that, and it is very interesting. However, it doesn't really explain the accuracy in my 37>34 remaining the same (apparently). I've done multiple conversions/reconversions and the lock time and accuracy seems the same always. Since the [Only registered and activated users can see links. ] (about 2 weeks ago), before i ran the side-by-side with the 3590 i had used it as 3490 for only about an hour previously to that test and it was getting 3-8m and fast lock straight away.... Logically it seems to me that the different experiences with 37>34 has to be elsewhere. We're all using the same FW, so what's that leave .. hardware differences? I'll get another 3790 by the weekend, have a play around with it and compare to my current device.
