Anyone seeing strange ATU operation in v3?

ATU operation in v3 is strange. My 6700’s ATU operation is quite strange, since upgrading to v3. Setup: Flex6700, Limited Edition Maestro ‘A’ model Local network, 6700 via Ethernet, Maestro via WiFi (both on same subnet) SteppIR, controlled via USB serial cable on the 6700 When I change bands, my SteppIR tunes to the new band and shows an VSWR of about 1.5:1, which is fine; however, when I hit the ATU button, the radio does a single quick Tx and illuminates the ATU button. When I retest the VSWR, it shows the same value, 1.5:1. When I reinstall v2.4.19, the ATU operates ‘normally ‘... The radio does several Tx operations, relays click and when complete, the VSWR is 1.1:1 or better. Yes, I know that 1.5:1 is quite good and that if I did some small SteppIR adjustments, I could get 1.1:1 directly. The ATU will be needed on my 6m - 80m End-Fed wire antenna, when it goes up. Anybody else seeing this? 73’s de Mike wa6fxt

Tim, Thanks. I look forward to the v3 maintenance release. Mike

I have the same issue. It tunes then bounces back to bypass.

My ATU issue has another manifestation: SmartSDR (on local computer) ATU function works properly most of the time in all modes, but on my Maestro the ATU only works in a mode with carrier. I know this general area was reported ~ 8 months ago, has the proposed fix been implemented yet? Thanks!
