What's in this update
- CAT: OM command response shortened to OMQC;
- CAT: KY command set text is now a circular buffer; if full, it returns ?;
- CAT: KY command get is KYn; where n = 0 if buffer < 75% full, 1 if buffer > 75% full, 2 if buffer empty and previous sending is complete
- CAT: Sent message via KY is immediately decoded on screen at message completion, without delay or corruption by receive signals
- CAT: TB command get, the 3rd response character is now number of remaining characters to be sent;
- CAT: QU command set now clears the unsoliticted update event flags
- Experimental modification for better output signal on 6m band
- Enable sidetone during CW beacon operation
- Removed GPS Data menu, and now Cal menus show "Waiting" while waiting for GPS lock, protect against from missed 1pps
- Sidetone volume now beeps every time it is changed while in the menu
- New menu item 7.11 controls Backlight (QCX-mini only)
- Double-click rotary encoder toggles backlight temporarily (not saved to EEPROM)
- Experimental support for 160m operation; this requires a 12MHz reference crystal for the Si5351A
- Eliminate low power "backwave" during key-up in Semi-QSK mode
- Added Morse prosigns AR, KN and SK/VA. New menu "5.7 VA" if set to ON selects VA, otherwise SK
- Bug fix: When beacon enabled, started on ref freq at power up, until you went into a sub-menu and exited
- Bug fix: CAT: Corrected bug command circular buffer that corrupted commands sometimes
- Bug fix: CAT: Increased reliability of comms by increasing wait timeout for incoming characters
- Bug fix: CAT: If the command buffer overflows, truncate the current CAT command to prevent the overflow
- Bug fix: CAT: Updating keyer speed can no longer cause occasional display corruption
