Looks like I was able to get Xiegu X6100 running succesfully with VaraAC and laptop. Some filter issues have to be still investigated.

First test with VaraAC V6.2.4 new X25 broadcast mode was also working properly. Here is small example QSO with DK1QG. Many thanks Chris about this great little test!

Broadcast mode is just great addition. Its like UI APRS messaging, but now integrated into VaraAC program with other features running at the same time.

Normal QSO test was also working pretty well. This time many thanks for Heiner, DL1EKY!

Next steps are to get Winlink RMS Express configured and running with that my new used laptop dedicated to mobile HF operation. Some updates coming also from that setup especially when its running in a car.
