wouldn’t it be easier to use a call like “CQ SOTA M1EYP”?
It does not matter on which frequency you are sending as WSJT is handling this for you.
You just have to pick up the station in the WSJT Window, and double click.
As a QRP station it is better find a clear spot, so that QRO stations won’t disturb your transmition… Your listening on the frequency of the transmitting station, but you are staying on your clear spot. You might have to set the option not to move your transmitting frequency. Works very well.
Checking regularely that your transmitting frequency is clear will help to increase the number of QSOs. You can move around … even in the middle of the QSO. WSJT handles this for you.
