VX3.20 / V3.20 02/06/24 -> chirp 48
-------------------------------------------------- --------------------------------
- fixed bug on calculation for upconverter
- fixed bug on Live decode DTMF

- speeded up scanning of memories and VFO
- changed the filter switching frequency in TX from 210 to 230 MHz*
  * NOTE - v3.14 cut frequency was set to 240 MHz.,
  v3.15 - v3.18 set it to 210 MHz. recommend avoid those versions 
  if using radio on 222 MHz band. Use either 3.14 or 3.20 and up.
- recalibrated all BW options with improved sensitivity
- changed menu item from SATCOM to BOOST with improved reception

- added AGC NORM option
- added new menu item 56 SetVfo replaces DualRx
- added dual watch Link option
- added Split option
- added separate memory group selection for VFO
- added side selection for Scrambler
- added dual watch with FM radio
- added 3 more BW settings for a total of 10
- added SMeter bar also to FM reception (display not exact but indicative)
- added frequency indicator over Ghz on double VFO
- added battery voltage calibration function and icon thresholds

VX3.18 / V3.18 05/20/24 -> chirp 43
- fixed bug on RxTone and Dual watch

IJV firmware v3.17 05/16/2024:
- fixed bug on quick frequency entry
- fixed bug on BW storage

IJV firmware v3.16 05/12/2024:
- fixed bugs with dual RX active (tsql and adjustments)
- fixed display freeze bug with all functions activated
- fixed bug with tsql and squelch 0
- reset F on Xit r Rit
- definitively eliminated all annoying POPs in reception 
 when changing frequencies
- set by default 12K on BW because it has proven to be 
 the best value
- added further level to squelch 0-9 normal, 10(NO RX) 
 reception block
- added battery voltage to beacon string
- added Flock entry (10m) for those who have made the 
 circuit modification for 10 m
- added the possibility of modifying the exchange frequency 
 of the vhf/uhf filters from 200 to 280 MHz on reception, 
 which can only be set by chirp
- added the possibility of blocking the TX in the 
 memories settable by chirp
- added GREEN LED indicator as an indicator of I/O operations 
 on eeprom (formatting and reading/writing data)
- added auto-completion of frequency entry with M key
- added dot separating last 2 digits on memory display 
 Name + freq

Version 3.15:
- fixed bug on rfgain selection with pressing exit or ptt
- fixed bug on group selection with memory in M001
- fixed bug on band filter switching with shift or dual watch enabled.
- fixed bug on key repetition after PTT
- corrected step with FastCopy.
- Crossband ex TX VFO function eliminated,it was actually useless
- modified start selection, PTT is no longer needed in association 
 with other keys
- changed basic settings with BW at 18k instead of 25k
- changed the step values ​​from 20Hz to 10 Hz, added 500 Hz and 
 removed 200 kHz
- changed the DTMF lists from 3 to 8 characters
- speeded up dual watch times
- improved DTMF management with the D CALL function which allows 
 automatic answering and/or call waiting
- added new PTT Toggle function that can be activated at power on 
 with the * button (note: it only works with FM)
- added automaticity on single VFO to avoid the initial zero for 
 first digit > 1
- added smeter display when adjusting the RF Gain
- added new function to block reception on one vfo and transmit on 
 the other (replaces cross band more efficiently)
- added display of the squelch value directly on the single VFO
- code optimization

Version 3.14:
- fixed Bug on RFGain display update with double VFO on the same band
- fixed bug on Beacon Transmission in double VFO
- fixed bug on setting scan limits with shift enabled
- fixed bug on saving existing memory
- fixed bug on menu setting for AGC.
- fixed bug on restarting scanning after Tone Search.
- automatic band change on search
- modified scanning now excludes WFM broadcast memories a priori without activating the Skip.
- modified smeter bar made smaller for better layout on the screen
- improved FM reception when turned on.
- entered the command F + 4 from the keyboard to skip memory scanning
- automatic deactivation of the monitor when starting the scan
- added function in Beacon mode to call alternatively on 2 frequencies
- added in Dual VFO display RF Gain and AGC indicator for each VFO
- added functions for serial communication
- code optimization.
