What is the proper behavior of the 6600M ATU?

Yes I've read the manual. What is the proper behavior of the 6600M ATU. In either Memory or Manual mode, if I press and hold the ATU button it looks to toggle between Tune and Bypass. In the TUNE mode if I press and release the ATU button, the MOX, TUNE and ATU buttons light up red for a half second or less but the ATU does not seek a tune solution. I hear no relays chattering and there is no change of SWR. I get the same results on both ANT 1 and ANT 2 and have tried on different antennas. The un-tuned SWR I am starting with is in the 2.5-5:1 range depending on the antenna, band and frequency. What am I doing wrong / missing?

Hit the ATU button, it will key and tune the radio to the Antenna, IF the Tuner is NOT required or tuning is out of the tuner range it will turn off the ATU LED.
Hope this helps.

when I do that the MOX, TUNE and ATU buttons light red for a half second or less. I cannot say the ATU is doing anything at all.

Do not press and hold. Press and release the button to initiate an ATU tuning cycle

I tried the ATU on Doug's 6600m last night. After a touch of the ATU button the rig goes into transmit and quickly returns to receive. Not a hint of a relay click or an attempt at a tuning cycle.
This was done on the 40m band into an antenna that had a 2.5:1 swr at that particular frequency.
This evening I tried the ATU via my Maestro which connects to a 6700 here at my shack. I chose an antenna and frequency on 40m where the swr is 1.0:1. A quick touch of the ATU button starts a tune cycle and I hear at least one relay click. When I moved the vfo to a frequency with an swr of 2.5:1 (around 7.2mhz on my 2 element yagi tuned for cw) I touched the tune button and it went into a full tune cylce that lasted a couple seconds. The result was an swr of 1.0:1.
I've been looking around the menu's, is there an SWR cutoff setting for the tuner?
We did not try SmartSDR to see if it has the same result.

Were ATU memories enabled? If there is a memory for that frequency/antenna combination, it will not search extensively.0

Thanks for the idea Tim, we'll check that out.
One thing I did not mention is there was no change in SWR. After the tune cycle the swr remained at 2.5:1

I get the same results in either Memory or Manual ATU mode.

I did a Factory Restore boot up and now the ATU appears to behave normally and as expected.

A factory reset resulted in deleting the ATU memory database.0

Maybe so Tim but a) how did memories get set when my radio was in Austin for CODEC replacement and 2) before the reset, two operators could not make the ATU function in either Memory or Manual mode. The ATU made no attempt to match a 2.5:1 SWR. in either mode. Hopefully the reset was all it needed and I won't have any more issues.

Looking forward to an answer to this.0
