Ian KD8CEC has released his latest firmware. This requires a minor configuration flag to be set to your µBITx version (3, 4 or 5) in the sketch before compiling and uploading the code to your µBITx.
Earlier µBITx versions do not require upgrading as no new features have been added to the firmware other than compatibility with the new v5 board.
Ian KD8CEC has announced a beta version of his firmware (Version 1.12) for the uBITX V5 board. He has written an article about it here.
All existing firmware functions for V3 and V4 are available on the V5 beta.
The same version of uBITX Manager will work with the v5 Board.
Only the LPF control and the frequency control part are changed in the V5 code. Ian has released firmware V1.121 for V5.
Nick VK4PP notes that custom filter section in uBITx Manager software for CEC firmware allows for configuring LPF daughter boards and is very easy to setup.
Ian KD8CEC has released version 1.1 of his CEC firmware. This the first major release since Beta version 1.097. He has also released new versions of uBITx Manager (for Windows) and Nextion screen firmware.
Version 1.1 includes all additions or improvements from the last non-Beta release version 1.08. This includes features and bug fixes addressed in Beta versions 1.09, 1.093, 1.095, and 1.097. No further changes have been made to the Version 1.097 Beta version.
You do not need to upgrade if you are using Version 1.097. This is the version with only the version number changed.

Nextion LCD or TJC LCD’s GUI have not changes since the 1.097 (Beta) distribution. If you are using a different GUI that is customized by other helpful developers, you should not need to upgrade the firmware. Some screen sizes are still not supported in ver 1.097 (and therefore in version 1.1).

There are several alternative firmware versions available for use with the µBITx transceiver. So why has the KD8CEC firmware been so successful with uBITx owners?
Some key reasons put forward by uBITx.net:
- KD8CEC firmware is fully compatible with the standard issue kit. No hardware changes are required to make it work. This is a critical point of difference with all of the other variants, and probably the most important factor associated with the success of CEC firmware.
- No custom wiring changes are required when using the firmware. This is a further significant factor in widespread adoption.
- The firmware fixes problems that come with the factory firmware – although some argue that CW modes are still not fully addressed in the CEC firmware.
- Using CEC firmware means no loss of features from the default factory firmware. Other alternatives offer fewer or different features from the factory firmware.
- Users are familiar with the user interface, as it reflects the default firmware’s “look and feel” with the standard display supplied with the kit.
- It is easy to upload a hex file to the Raduino. Constructors without a working knowledge of the Arduino IDE can upload files easily.
- All full releases of CEC Firmware are available as open source firmware. This follows the same structure as the original code, although most of the code has been replaced. Open source is not released for beta versions (and for good reason).
- No additional processor is required, unlike other firmware variants. A mechanism for adding additional processors has been added in ver 1.097 (Beta). This promises a future where multiple processor support will be available. You won’t be locked into a single processor type.
- Addition of a Nextion display or additional processor is relatively straightforward.
- The firmware on the Nextion display can be edited by others to provide a different “look and feel” or to add or subtract features. This is independent of the firmware for the transceiver.
Remi F1MQJ has modified the manufacturer’s v4.3 original firmware (published on may 23 2018) to include communication with KD8CEC memory manager.
This could be very useful for those wanting to stick with the HF Signals latest firmware, while making it easier to view or update initialisation settings, such as calibration of frequency or setting the BFO injection point, in the original firmware.
Modifications are the same as those described by Ian KD8CEC here but are adapted to the HF Signals V4.3 original firmware.

Ian KD8CEC has been busy again in conjuring up new features in his CEC firmware. He is tempting us with descriptions of two new features:
- Nextion display update that makes it easy to adjust keying speed and to select the keyer type (Iambic A, Iambic B or Straight Key) even while in TX
- Adding an additional arduino, connected to the Raduino via i2c, to provide an S-meter function.
The first feature is well explained by the photo above. The second feature is a bit more difficult to describe. By adding a US$3 additional arduino the µBITx now has double the number of analogue and digital ports and another 32K of program space. This could be a fun ride! The first function is a basic one, but an important one. A much more sensitive S-meter. But wait there’s more, as yet to be fully described. If you already have a Nextion screen, it looks like you may be in line for a half decent signal analyser function.
Connecting up the arduino
The circuit is pretty straight forward, and involves just a couple of resistors and a capacitor, along with wiring to +5v and ground, and the two i2c lines.
W0EB and W2CTX have just completed and released a powerful new set of firmware for their BITeensio card.
Details about the BITeensio and links to the firmware can be found on the website at www.w0eb.com.
“As of this morning, July 8, we have released a powerful new version of the firmware for our BITeensio card, V6.00R, that utilizes the Teensy 3.6’s capability to utilize USB “Host” mode and connect a standard USB ASCII keyboard (many wireless ones work too). PJRC (the people that make the Teensy www.pjrc.com ) offer a standard USB cable thatcan plug into the Teensy. (You do have to add a 5 pin header to the Teensy 3.6 board) on the same side, and just to the right of the USB “Micro B” connector into which you will be able to plug the standard USB 2.0 cable. The red wire (+5V) must be plugged into the pin indicated by a white square in the outline on the Teensy 3.6.In this version, we have implemented a comprehensive command list that allows many of the standard “menu” commands, including the operating frequency, to be entered using the keyboard.
“Also included is a brand new Keyboard CW keyer that uses most of the K1EL keyboard keyer’s character/key mapping. The V6.00R firmware is released as pre-compiled “HEX” files and placed in the appropriate directory of the “Files” link on the www.w0eb.com website. We are not denying anyone that wants it the source code, but you will have to ask for it with the understanding that if you cannot compile it or if you modify it, you are on your own as we just don’t have time to troubleshoot it for you.”
The KD8CEC firmware provides a lot of customisation features through uBITx Manager software. Many user of Ian’s firmware are not aware of all the built-in features of his firmware. This is one such instance!
JJ1EPE raised a concern that his display in CW mode was “off frequency”. Well, it was from his perspective, but then the display was all the time showing the TX frequency not the offset frequency where the station he was listening to.
CW offsets create headaches in how you represent the frequency on a display. In SSB the frequency you see on the display is the frequency of the suppressed carrier on receive and the same on transmit. If you tune to the carrier frequency of a received station you won’t hear anything. To get a sidetone we have to tune off the transmit frequency by a few hundred hertz. Most people have worked out how to set the offset on the uBITx.
The standard that Ian KD8CEC has applied is to always show the TX frequency by default (except where RIT or SPLIT mode is selected).
However, if you want to change the approach, do the following in uBITX Manager:
– Enable Adjust CW Frequency
– Shift Display Frequency on CWL, CWU Mode
If you select this function, the LCD will show the frequency at which the radio is being transmitted (the offset you prefer is added or subtracted to the actual RX frequency reflecting the CW-L or CW-U mode selected). This may be just the thing you were looking for!
Michael VE3WMB figured after playing around with the KD8CEC firmware for a while that he would prefer to have the Main VFO frequency and Mode displayed in the top line, instead of the bottom line of the display and the secondary info (VFO B etc) on the bottom line of his display.
Under ‘User Interface’ of the uBitx Memory Manager application (scroll way down), checking the ‘1/2 Line Toggle’ works to swap the first and 2nd lines on the display. No coding is required to achieve this.
