Hi Hans
Just a minor point.? I have found when having 2 com ports open at the same time i.e. Putty and WSJT-X, the 'microphone test' in Putty doesn't work - there may be a couple of bars but it stops at that point.? However on closing one of the ports, the 'microphone test' functions properly.
Cheers
