What's in this update
- bug fixed: If "Steer WinKey CW/PTT" on MK2R was unchecked and TX focus auto control should follow "Two PTTs" then TX focus was forced according to WinKey PinConfig even if WinKEy PTT was inactive. It overrided all other PTT sources used to determine TX focus. Now Tx focus is not updated until WinKey PTT is active.
