#IMPORTANT INFORMATION

• A bug was found in version 1.0, When CW Keytype is set to IAMBCA and IAMBCB, there was a problem that switching to RX is not performed well when CAT communication is performed. If CW key type is straight, it works normally. This bug has been fixed and changed to version 1.01.
• Now Release Version 1.01 on my blog (http://www.hamskey.com)
• You can download and compiled hex file and uBITX Manager application on my blog (http://www.hamskey.com)

#NOTICE

I received uBITX a month ago and found that many features are required, and began coding with the idea of implementing minimal functionality as a general hf transceiver rather than an experimental device.

Most of the basic functions of the HF transceiver I thought were implemented. The minimum basic specification for uBITX to operate as a radio, I think it is finished. So I will release the 0.27 version and if I do not see the bug anymore, I will try to change the version name to 1.0. Now uBITX is an HF radio and will be able to join you in your happy hams life. Based on this source, you can use it by adding functions.

I am going to do a new project based on this source, linking with WSPR, WSJT-X and so on. Of course, this repository is still running. If you have any bugs or ideas, please feel free to email me.

Prepared or finished tasks for the next version

• Include WSPR Beacone function - (implement other new repository) complete experiment need solve : Big code size (over 100%, then remove some functions for experment) need replace Si5351 Library (increase risk and need more beta tester) W3PM sent me his wonderful source - using BITX, GPS

REVISION RECORD

1.02 (working)

• Applied CW Start Delay to New CW Key logic

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)
• Change CW Key Select type, (toggle -> select by dial)

0.32

• Added function Scroll Frequencty on upper line
• Added Example code for Draw meter and remarked (you can see and use this code in source codes)
• Added Split function, just toggle VFOs when TX/RX

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)

• Dual VFO Dial Lock (vfoA Dial lock)
• Support Ham band on uBITX default Hamband is regeion1 but customize by uBITX Manager Software
• Advanced ham band options (Tx control) for use in all countries. You can adjust it yourself.
• Convenience of band movement

0.26

• 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

0.21

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

0.20

• original uBITX software (Ashhar Farhan)
