The unselected VFO was read only when split was on, so a dual-receiver rig's second dial sat blank on the console. It is now read on the same slow beat regardless. And engaging split copies the main's mode (and data flag) onto the TX VFO with 0x26 01 — a split whose TX VFO still speaks yesterday's mode transmits FM into a CW pileup; rigs that predate 0x26 NAK it harmlessly.
