Installing SWR and RF Power Sensor in uBITX I modified the I2C Type Signal Meter firmware to display SWR when using Nextion LCD in uBITX. Release I2C Type Signal Meter firmware V0.8, If you want something stable, use V 0.7 (V0.8 is a beta version) Now if you are using the I2C Type Signal Meter, you do not need to update the uBITX firmware and the Nextion LCD GUI. You only need to upload the firmware of the I2C Type Signal Meter to V0.8.

Release CEC Firmware v1.121 for uBITX V5 I did some experiments with the help of a beta tester with V5. he experiment was mainly to pass the modified filter. You can see videos related to the experiment below. (The firmware download link is at the bottom of this post)

What's new with uBITX V5 #2 -  LPF and other UBITX Version 5 with improved  filter for spur has recently been released. I always appreciate Ashhar Farhan, who always makes great work. Information on uBITX Version 5 can be found on the link below. and you can download to sourcecode with schematic https://github.com/afarhan/ubitx_v5 uBitx v5 Changes https://groups.io/g/BITX20/wiki/uBitx-v5-Changes. What's new with uBITX V5 #1 http://www.hamskey.com/2019/02/whats-new-with-ubitx-v5-1-changed-if.html At the end of this article is a link to download a CEC firmware test version.

What's new with uBITX V5 #1 - Changed IF frequency UBITX Version 5 with improved  filter for spur has recently been released. I always appreciate Ashhar Farhan, who always makes great work. Information on uBITX Version 5 can be found on the link below. and you can download to sourcecode with schematic https://github.com/afarhan/ubitx_v5 uBitx v5 Changes https://groups.io/g/BITX20/wiki/uBitx-v5-Changes.

uBITX Firmware CEC Version 1.1 Release Version 1.1 is the first major release since 1.097,  I will release it after a 50-day beta test. Version 1.1 includes all additions or improvements from 1.08 to 1.09, 1.093, 1.095, 1.097 

CAT Support uBITX Firmware CEC Version 1.07 (Beta Version) Release The beta version 1.07x was officially released as version 1.08 http://www.hamskey.com/2018/05/ubitx-firmware-cec-version-108-release.html

WSPR WSPR is short for "Weak Signal Propagation Reporter". For more information on wspr see the links below https://en.wikipedia.org/wiki/WSPR_(amateur_radio_software) https://physics.princeton.edu/pulsar/k1jt/wspr.html http://wsprnet.org/drupal/

Already this issue is known to Arduino users. and There are also various solutions to this. If you are an Arduino or BITX (uBITX) user, you've already experienced it and have solved the problem. This article is for those who are new to Arduino like me. I spent a lot of time thinking that this problem from my firmware. In other words, I am an old firmware developer, but I first tried it (arduino).

uBITX is based on Arduino Nano. So uBITX's firmware upgrade method is the same as Arduino. There are two ways to upgrade the firmware of uBITX. The first is to compile the source from the Arduino IDE, and the second is to upload the compiled hex file using the Firmware Upgrade Tool. I'll show you how to upload a compiled hex file as a second method. 1.Connect the uBITX's USB cable to the computer. 2.Run Device Manager on your computer.   The way to open the Device Manager for each OS Version differs slightly.   In most Windows, you can easily launch the Device Manager by running.   On your computer, press the Windows key + R.    Type devmgmt.msc and press OK Button. On most operating systems, there will be a serial port named Ports with CH340. If so, the next step is skipped. If the serial port is not installed as below, you need to install the driver. Included in uBITX is the Adonano, which uses the CH340 USB To UART part....
