OK I want to try again to make my point and I basically agree with Hal.
I understand there is a need for RRR and closing the contact with 73 or a custom thank you is the courteous thing to do.
My issue is if I send RR73 after receiving a signal report and the contact replies with RRR we are locked in a loop until one of manually sends 73 or just gives up.
Why doesn't WSJTx send 73 when it sees the RRR and has already sent a RR73?
