I have used the Bob Freeth G4HFQ program available at?https://www.m0lxq.com/g4hfq/download.html There are also programmes available for several other Yaesu radios; I use the 7900 & 8900 versions also.? There is a PDF document associated with the programmes which has the passwords to activate the software for life.
