Hi  just start playing whit my 6700  and hit a wall   ,let me explain 

i listen some rag-chew on 80m  and follow net on VHF D-Star  all work nicely ... (SCU0 to HF ,SCU1  VHF or something like that )

but if try to open another VHF slice  i lost the HF   all 3 slice go to VHF ? just like if both SCU was now used for VHF ?? whit heavy HF attenuation due to filter  
why it not try to reuse the already "VHF" SCU and leave HF one alone ? 

and how i may control witch one of SCU was used for VHF slice ?

So you are creating a new panadapter which by default creates a new slice rather than adding a slice to an existing panadapter.  I understand now.

First, make sure you are running the latest SmartSDR software (1.5.1) since we addressed a few of these issue in some later versions.  

What I suspect has happened is that the third panadapter has persistence associated with it that forces the antenna on the HF (80m) panadapter to be associated with the a Nyquist zone in the VHF range.  

I would clear your band persistence.  Here is how to do this.
  1. Open the Profiles->Import/Export Profiles..
  2. Export your profile data but do not select Preferences
  3. Shut down SmartSDR and power off the radio
  4. Press and hold the OK button while momentarily pressing the power button to turn on the radio
  5. Release the OK button when the lower LED turns white
  6. Allow the radio to start up normally.
  7. Import the profile from the export done in step 2.  The file will be on your desktop.

Now you have a default persistence database in your radio.
