Using SunSDR2 DX with the stealth loop from I3VHF.

Upgrade the ATU to v4.0.9
Connect null modem cable to the ATU and computer
Configure ATU to use CAT MODE 3
In SunSDR CAT menu enable ECATv1

Now the loop is tuning either by FULL AUTO, SEMI AUTO or DISABLED depending on what you want.

Made a program so that you can use EESDR3 or EESDR2 with TCI:

For linux and windows

To automatic tune when changing frequency was probably not the best solution.
The new version now require that in EESDR you press TUNE and then de-select it.
When the tranceiver goes out of TUNE mode the ATU for the StealthLoop starts tuning.

This way its not possible to TX when the ATU starts as this can hurt your ATU.

Will download and check it out as I am using V3
Thanks
