DDUtil TX 1 - 4 Inhibit

I am using the TX1 port from my 6600 to key my ALS-600 amp. From a cold boot the Flex and Amp work perfect. 

I also use DDUtil to monitor my station and link into HRD without using the radio control part of HRD. Logging and Digital modes in HRD only.

After I open DDUtil, the TX 1 - 4 outputs of the 6600 are disabled. 

To re-enable TX 1 - 4, all I need to do on the active slice is to switch from Xmit Ant 1 to Ant 2, then switch back to Ant 1. This simple two clicks on the screen corrects the issue and seems to keep it that way until I do another full power cycle of the radio and restart DDUtil. Changing Profiles also correct the issue.

Tim has been very helpful and we now know that this is something to do with either a setting in DDUtil or a command it sends when it boots. I have searched the manual and help screens to see if there is a setting I can change to not impact the status of TX 1 - 4 when DDUtil boots. So far I have not found anything. OK, I may have missed it, there is a lot of information out there.

Has anyone else seen this issue or know what setting I can change to eliminate this issue. 

Thanks for any help and support.

    NOTE: Pay no attention to the pop-up help item displayed above, It is for the last item checked: "DDUtil Follows Amp PTT"

    I have an ALS-600 and use DDUtil.  I have the "Enable" box at the upper left checked, but no other boxes checked.  Since the ALS-600 is not a "supported" amp, most of the settings that apply to the amp are not relevant in DDUtil.  The Auto Drive selections and power levels are, however, applicable.  Note that the DDUtil icon on your Windows task bar shows the amp's status: Green = Operate, Yellow = Standby - These can be changed with OPER/STBY button at the upper area of the DDUtil window.  Having the "Enable" box unchecked will cause the problem your are experiencing when DDUtil starts.
