Display On/Off implemented This feature came too late for the documentation but is a kind of self-explaining.

Minor bug fixing

Also today we release the updated User Manual in German and English (can befound in Docu aera). Some of the features out of the last SW release were not described in the user manual, so it was time to do some work on documentation as well.

Joerg DF9LJ did a video about his antenna switching using the external antenna switch feature.

I recommend to watch that video for a bett​er understanding about the new feature.
