/* WELCOME TO THE OPEN SOURCE USDX PROJECT 2022 AND ONWARDS!
This version is for all uSDX/uSDR transceivers, release numbers are 4.XXx.
Compiled and programmed using Arudino IDE 2.0.4, available from www.arduinio.cc
To support the add-on module for uSDX with powerful DSP processor, version numbers will be 3.XXx.
*** READ ALL THE NOTES here and ask questions on the FB "USDX USDR" group before programming, it may save a lot of heartache!
Our intention is to make the uSDX a great option, with all the facilities and interfaces you can imagine!
The quadrature mixer (designed by Dan Tayloe N7VE) in the uSDX makes it as good a receiver as a professional rig, when built correctly.
The TX modulation has been improved and gets good reports, and with the add-on module it can be as good as the best out there.
Enjoy!
73 Rob, GW8RDI

// G8RDI Modifications log:
#define VERSION "4.00c" // Fixed format "9.99z" : Additions and changes Copyright 2022-2023 GW8RDI - You can use and distribute if you maintain the copyright message, commercial use is prohibited.
// 2022/03/04 - Added delay to show serial number at start - G8RDI mod
// Added band change direction based on last freq step directions. See "case BE | DC:" - GW8RDI mod
// Set PB3/PB5 to output in init to drive LCD backlight
// 2022/03/05 - Release 1.02wA2 2022/03/20 : Added Cat 8.6 ad QUAD enable 8.7 menu items
// 2022/03/06 - With MORE_MIC_GAIN enabled & QUAD disabled, SSB TX voice is sounding much better!
// 2022/04/24 - Release 1.02wA3: Fixed band dir. bug
// 2022/05/08 - Added KEEP_BAND_DATA to maintain last freq and mode set on each band.
// 2022/05/09 - Release 1.02wA4 : Maintains last freq and mode set for each band, up to 9 bands set. Added error code display.
// 2022/05/11 - Changed menu to cycle end-start, start-end
// 2022/07/19 - Added full CW mode update on band change, minor fixes
// 2022/07/19 - Release 1.02wA5 : Maintains last freq and mode set for each band, up to 9 bands set. Added error code display.
// 2022/07/28 - Release 1.02wA6 : Minor changes. Reduced CW message duplication to release more memory.
// 2022/08/16 - Release 1.02wA7 : Directional band-change went in the wrong direction if SWAP_ROTARY was not enabled. This fix solves that issue.
// 2022/08/19 - Release 1.02wA8 : Directional band-change saved last band-mode to Flash, and not mode of band changed to, causing incorrect mode restore if shutdown without band change. Minor other changes, DEBUG modes changes callsign.
// 2022/08/22 - Release 1.02wA8a : Red Corners Unit: CW messages updated, Band menu fix as was showing 6m in the list. Added WHITE_CORNERS to config list.
// 2022/08/22 - Release 2.00a : Jumped version to avoid confusion with prev. releases. Added SWR, 115200 baud CAT, experimental changes to AM and FM, and minor tidy up
// 2022/10/12 - Release 2.00b : NR stays as last used.
// 2022/11/06 - Release 2.00c : #define KEYER CW keyer for Iambic -> NOTE: Auto CW msg sending aborts if not installed, and 700Hz filter selection gives reduced gain.
// : Added new post mag IQ filter, added BlackBrick config.
// 2023/02/09 - Release 2.00d : Added CAT freq. error handling, in RIT mode the TX freq. is now displayed, plus FIR noise filter, see #define NR_FIR below. NR 0-2 is 1.02x method, 3-8 is now FIR DSP filter method to be used with Full b/w and Att2 = 2
// 2023/02/09 - Release 2.00e : Ammended code to support +/- 99 KHz RIT receiver offset, and added CAT command to set the RIT offset.
// 2023/03/14 - Release 2.00f : Ammended code with new "TT" CAT command to set a TX offset frequency; see CAT_XO_CMD. Minor improvements for setting mode display, etc.
// 2023/03/14 - Update to 2.00f : Ammended code as missing #ifdef KEEP_BAND_DATA on line 5922
// 2023/04/01 - Release 4.00a : Changed to version 4.00 as DL2MAN jumped his version up to 2.00! CAT now enables directly from the menu without needing a reboot to activate! CAT MDx; now refreshes LCD fully after CW mode.
// Re-coded KEEP_BAND_DATA switch statements which freed 328 bytes!!
// 2023/04/11 - Release 4.00b : Fixed CAT mode change to allow it to select AM and FM, AM important to correctly track IQ flip. Also commented-out redundant BE | DC for mode change, as now used for directional band change.
// RIT mode now allows mode to be changed.
// 2023/04/17 - Release 4.00c : (UPDATE-2) Ammended configuration for TRUSDX clone so that latched-relay band switching and SWR selection is included.
// : Added new post mag IQ filter, added BlackBrick config.
// : todo see "// xyzzy Test with i_d"
// NOTE update #define VERSION "????" above!
// See "BACKLOG:" FOR PENDING WORK CARRIED FORWARD
// *** Use of this modified software is at the users risk *** PLEASE READ THE INSTRUCTIONS AVAILABLE IN THE FB GROUP "uSDX uSDR Radios" or uSDX Group IO online.
// Notes: To have CW tone in the menu, enable #define FILTER_700HZ. You´ll need to find 28 bytes depending on your config, i.e. disabling #define DIAG
