ATU Not Finding Low SWR in SmartSDR v3.1.12

edited June 2020 in FLEX-6000 Signature Series
I am running a Flex 6300 and recently upgraded SmartSDR to v3.1.12 from v1, I notice the ATU does not find a good match for low SWR as smoothly as in v1. I have to push the ATU button sometimes several times to get a good SWR. This is occuring on an antenna which had previously tuned right up. Any suggestions? Thanks.

    That's my experience. ATU is a critical feature. Might have to dump v3 and retreat to v1. ATU is much more critical than remote and multiflex. Bummer. Hate it when an upgrade compromises features that previously worked well.

    Actually, I believe Flex _has_ acknowledged it as a problem/bug, but it seems that the solution is not as easy nor straightforward as we would have liked it to be.  It was first recognized in the releases following 2.4.9.  (I.e. 2.4.9 is the last version with the 'old' version of ATU tuning which works correctly.)  When I first identified the problem, Flex acknowledged it (sorry, I've forgotten the #) and suggested I stay with 2.4.9 until it is resolved.

    Hi Craig... as I note in my response above 2.4.9 has the 'old' ATU software and works correctly.  (rather than reverting all the way back to v1.x).  Just a thought.

    Thanks a bunch VE7ATJ. Does my v3 license entitle me to use v2.4.9?

    Please consult with Flex support before you try rolling back.  There are certain procedures and limitations that need to be understood and followed in order to successfully roll back without corrupting the database.

    I only got my 6300 a week ago. Previously had a 3000 and the a 5000. Instantly noticed the flakey ATU. Hope they get it sorted soon and this IS A DEAL BREAKER
