If the above or any other DX station did not give you a serial number, no matter how many times you pleaded with him/her to do so, it isn't a valid contact for the contest and should not be logged as such, PERIOD. If you entered HNY as the serial number, assuming your logging software accepted letters instead of figures, the QSO will be 'bounced' come log checking time. Eddie W6/G0AZT
