richsch, When you select "Auto Q", there is no need to switch direct sampling manually. It will be automatically switch on/off when your LO frequency goes below 24 MHz. You're don't need to change anything, just change LO and direct sampling will be automatically enabled and disabled. You can forgot about this setting when "Auto Q" is selected. :)

If you want manual switch, then use:
- "Disabled" to disable direct sampling (to receive 24 - 1700 MHz)
- "Q input" to enable direct sampling on Q branch (to receive 0...24 MHz)

Just tested, all works as expected. If I don't understand your issue, please explain more details.

You can find the latest version (1.1.1.7) here: viewtopic.php?f=1&t=4710&start=20#p11796

it works fine, so there is nothing to change. I even don't know what feature to add :)
