    Default V1 Software Versions vs. Performance

    I believe the latest V1s are rev 3.858 or so. I am considering a unit with rev. 3.819. What are some of the "improvements" made since the 3.819 rev. Would it be worth it to upgrade a 3.819 unit to the latest software?

    Ghosting is when it says there is 4 in the bogey display, but in reality it is only 1 or 2. THe radar signals are just bouncing off everything and the unit is lead to believe there is greater than the # of signals there really is.

    Thanks for the "ghosting" explanation!

    Just a suggestion for a thread/sticky with all the info we can gather on each revision just like the one above (thanks, jim), but for the full range of revisions. I know the info is scattered but it would be nice to have in one place.

    Hey, Jim, thanks for the list, I just wanted to ask you what is meant by the quoted sentence? Increase in response or sensitivity or just more frequencies covered?

    Thank you!

    Well, I actually quoted someone from VR, and they didn't give an explanation But, I'm pretty sure I know what it is:

    A while back Dilip and nvr2fast did some testing against some photo radar units, Gatsos I think, if you search old posts you'll find it. In Euro more, the V1 would miss these Gatsos, turns out that when they checked with Spec mode on a Belscort, the Gatsos were WAY off freq and outside the photo radar band that the V1 swept (34.3 GHz +/- 100 MHz). They reported this to Valentine Research.

    So, I am pretty sure that Valentine widened the sweep around 34.3 GHz photo radar. So I would say that a user of Euro mode would probably want 3.851 or later just to be safe.

    Hello, Jim, thanks for the explanation. I am aware about this issue and I have also informed V1 about the width of sweep around 34.36 GHz for out-of-tune Multanovas (Ka). Also, there are some Ka band photo radars working on 34.0 GHz and maybe V1 corrected it. I guess they had. Maybe it's time to send it out for an upgrade

    Thanks!!
