What's in this update

  • Allow transmission while RIT adjustment is active
  • Allow transmission while keyer speed adjustment is active
  • Copy VFO A to B by Right button long press then Right button short press (within 1 second)
  • Copy VFO B to A by Right button long press then Right button double press (within 1 second)
  • Switch off DSP during transmit, improves responsiveness of keyer (DSP is not used during transmi​t)
  • Break character -...- changed from | to = on display
  • Dynamic calculation of Si5351A divisor rather than from a table based on band; enables changing band by preset freq
  • Remove menu 3.9 (Band) - no longer relevant
  • When in practice mode, 'P' is now displayed to the right of the frequency on the top row
  • New menu 4.10 "Strght mode", choice of Both/Tip/Ring (so mono jacks can work)
  • New menu 7.8 "Custom splsh", enables message 11 & 12 to be used as splash screen on power up (Factory reset is now 7.9)
  • Automatic protection against GPS keying the transmit; when GPS detected, automatically enters practice mode
  • WSPR encoding now re-encodes WSPR one transmit cycle sooner​, in cases where the Maidenhead grid changed
  • Bug fix: IAMBIC A mode keyer bug
  • Bug fix: Disappearing S-meter after changing some unrelated parameters in the menu
  • Bug fix: When CW decoder and S-meter both enabled, some digits of frequency display could get corrupted
  • Bug fix: Tuning while keying resulted in loud tone in headphones. Tuning during key-down is now disabled
  • Bug fix: Incorrect built-in bias caused CW decoder to track sending speed faster than it really was. Fix improves decoder
