• Reduce program size (97% -> 95%)

1.03

• Change eBFO Calibration Step (50 to 5)
• Change CW Frequency Display type

1.02

• Applied CW Start Delay to New CW Key logic (This is my mistake when applying the new CW Key Logic.Since uBITX operations are not significantly affected, this does not create a separate Release, It will be reflected in the next release.) - complete
• Modified CW Key Logic for Auto Key, (available AutoKey function by any cw keytype) - complete
• reduce cpu use usage (working)
• reduce (working)

1.01

• Fixed Cat problem with (IAMBIC A or B Selected) 1.0
• rename 0.30 to 1.0

0.35

• vfo to channel bug fixed (not saved mode -> fixed, channel has frequency and mode)
• add Channel tag (ch.1 ~ 10) by uBITX Manager
• add VFO to Channel, Channel To VFO

0.34

• TX Status check in auto Keysend logic
• optimize codes
• change default tune step size, and fixed bug
• change IF shift step (1Hz -> 50Hz)

0.33

• Added CWL, CWU Mode, (dont complete test yet)
• fixed VFO changed bug.
• Added Additional BFO for CWL, CWL
• Added IF Shift
• Change confirmation key PTT -> function key (not critical menus)

0.31

• Fixed CW ADC Range error
• Display Message on Upper Line (anothor VFO Frequency, Tune Step, Selected Key Type)

0.30

• implemented the function to monitor the value of all analog inputs. This allows you to monitor the status of the CW keys connected to your uBITX.
• possible to set the ADC range for CW Keying. If no setting is made, it will have the same range as the original code. If you set the CW Keying ADC Values using uBITX Manager 0.3, you can reduce the key error.
• Added the function to select Straight Key, IAMBICA, IAMBICB key from the menu.
• default Band select is Ham Band mode, if you want common type, long press function key at band select menu, uBITX Manager can be used to modify frequencies to suit your country.

0.29

• Remove the use of initialization values in BFO settings - using crruent value, if factory reset
• Select Tune Step, default 0, 20, 50, 100, 200, Use the uBITX Manager to set the steps value you want. You can select Step by pressing and holding the Function Key (1sec ~ 2sec).
• Modify Dial Lock Function, Press the Function key for more than 3 seconds to toggle dial lock.
• created a new frequency tune method. remove original source codes, Threshold has been applied to reduce malfunction. checked the continuity of the user operating to make natural tune possible.
• stabilize and remove many warning messages - by Pullrequest and merge
• Changed cw keying method. removed the original code and applied Ron's code and Improved compatibility with original hardware and CAT commnication. It can be used without modification of hardware.

0.28

• Fixed CAT problem with hamlib on Linux
• restore Protocol autorecovery logic

0.27 (First alpha test version, This will be renamed to the major version 1.0)

• only Beta tester released & source code share
• find a bug on none initial eeprom uBITX - Fixed (Check -> initialized & compatible original source code)
• change the version number 0.26 -> 0.27
• Prevent overflow bugs
• bug with linux based Hamlib (raspberry pi), It was perfect for the 0.224 version, but there was a problem for the 0.25 version.
  On Windows, ham deluxe, wsjt-x, jt65-hf, and fldigi were successfully run. Problem with Raspberry pi.

0.25

• Beta Version Released http://www.hamskey.com/2018/01/release-beta-version-of-cat-support.html
• Added CAT Protocol for uBITX
• Modified the default usb carrier value used when the setting is wrong.
• Fixed a routine to repair when the CAT protocol was interrupted.

0.24

• Program optimization reduce usage ram rate (string with M() optins)
• Optimized CAT protocol for wsjt-x, fldigi

0.23

• added delay_background() , replace almost delay() to delay_background for prevent timeout

• cat library compatible with FT-817 Command switch VFOA / VFOB, Read Write CW Speed Read Write CW Delay Time Read Write CW Pitch (with sidetone) All of these can be controlled by Hamradio deluxe.

• modified cat libray function for protocol for CAT communication is not broken in CW or TX mode

• Ability to change CW Delay

• Added Dial Lock function

• Add functions CW Start dely (TX -> CW interval)

• Automatic storage of VFO frequency It was implemented by storing it only once when the frequency stays 10 seconds or more after the change. (protect eeprom life)

0.22

• fixed screen Update Problem
• Frequency Display Problem - Problems occur below 1Mhz
• added function Enhanced CAT communication
• replace ubitx_cat.ino to cat_libs.ino
• Save mode when switching to VFOA / VFOB

• Fix the error that the frequency is over.
• fixed frequency display (alignment, point)

0.20

• original uBITX software (Ashhar Farhan)
