I'm new to Yaesu System Fusion/Wires-X. Actually, I'm pretty new to amateur radio in general. Just got licensed in January. I just got a FTM-7250D from a club member on Field Day, and have only made a few contacts. My question is, when logging the contacts into QRZ logbook, what do I choose for the mode? C4FM or Digital Voice? Does it even matter? I had been using C4FM, but then I got a request for confirmation from a contact who had used Digital Voice for the mode.
