Thanks, will try N1MMThere are many options. ARRL has Log Book of the World, QRZ.com has one which is online, and then the multiple applications you can download to your desktop such as N1MM Logger, N3FJP Log, Ham Radio Deluxe, etc... The desktop applications are capable of connect direct to the FT991A to assist with logging is one main feature of why hams use those... So you have many options and one way to pick one is to try one or two of them or all if you have the time. Hope this helps a little bit... Thanks.
