For this year CQWW in Macau, I purchased a writelog, I use my homecall BA7NQ to get the register code. When in contest, we move to Macau and use XX9C callsign, then I found, writelog can not change callsign. So, when in XX9C operation, all BY QSO was calculated to 0 point, and all XX9 QSO was calculated as 1 point.... How to fix this problem.... any answer is welcome! Thank you... 73! de BA7NQ Terry
