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?

Yes, there are two ATU defects that will be addressed in the upcoming maintenance release of SmartSDR v3.0
