The Yaesu FTM-500D. Coming March 2023. Some stand out features to me are. APRS 6w speaker PMG function Dual receive Wide receive, airband, etc. (108MHz to 999.995MHz) 16 character channel names Bluetooth MicroSD slot 50W (FTM-500DS is 20w) I was just about to get the FTM-300, so I'll be interested to compare them.
