Thanks for your fast reply and indications.
So, it should be a way to return to the primary frequency.
I tried to follow your instructions, but...something does not work for me...
When I right click inside the telnet window a menu window does open with a list of menus like: hold off receive text / enable telnet freeze / ...etc.../ login on program start.
But none of these menus are "reset radio 1/2 frequency", or "reset radio frequency", or anything related to that...
So, I do not know where to find the menu that you specified, to click on...! :(
Thanks again for your help, best 73,
