Thanks to Werner OE9FWV for taking me through my first pactor 2 connection and then and SSB QSO on Tuesday 3rd June.
I learnt a lot about how to use the ‘airmail software’ and also learnt that pactor 2 is fine for a terminal QSO and has the advantage it has a narrow bandwidth of about 500 Hz compared to 2,400 Hz of Pactor 3 and 4.
