The uBITX is a general coverage HF SSB/CW transceiver kit with features you NEED for operating ease, convenience and versatility. If works from 3 MHz to 30 MHz, with upto 12 watts on SSB and CW with a very sensitive receiver. It features digital tuning, dual VFOs, RIT, CW Keyer and more.  The uBITX is a general coverage HF SSB/CW transceiver kit with features you NEED for operating ease, convenience and versatility. It works from 3 MHz to 30 MHz, with upto 12 watts on SSB and CW with a very sensitive receiver. It features digital tuning, dual VFOs, RIT, CW Keyer and more.


The uBITX is a joy to operate. Press the tuning control to access all the features. Dual VFOs, RIT, CW speed, sideband selection. etc. are all accessible from a single menu. The transceiver automatically selects the proper sideband for you (you can override it too).

Technical Specifications

The uBITX is an understandable radio. The complexity is kept to a minimum so you can always repair and make changes if you so desire.

The the uBITX has a carefully thought out operator interface. The tuning knob features a number of menu options on a click. From RIT, to dual VFOs, to the keyer and many more featuers are all accessible from the tuning knob by simply tapping on it.There are intelligent defaults everywhere (these are easily overriden). Example : below 10 MHz, it auto-selects LSB and vice versa. To operate CW, you just press the morse key.

Architecture The uBITX uses upconversion to the first IF of 45 MHz. This eliminates the need for a large number of band pass filters, keeping the design simple and virtually image free. The roofing filter at 45 MHz is 15 KHz wide. The signal is then down-converted to 12 MHz where a low ripple SSB filter with 8 crystals is used to provide a sparkling audio.

The transmitter has push-pull PA using two IRF510s for a clean output. The low cost IRF510s are not  a bother to replace should you ever blow them up.

Receiver :

  • Sensitivity a 0.2uv signal is clearly audible
  • Selectivity 2.4 KHz,  low ripple SSB filter with 8 crystals
  • RIT (Receiver Incremental Tuning)
  • Continuous coverage from 500 KHz to 30 MHz
  • Sideband selection
  • Dent-less encoder tuning. Tunes with larger step rates when tuned quickly


  • More than 10 watts upto 10 MHz, 7 watts upto 21 MHz, 2 watts on 28 MHz
  • CW transmit with the built-in keyer
  • Uses   IRF510s  x 2 as PA and  2N3904 x 4 drivers in push-pull mode for low distortion transmission. Blown IRF510 are inexpensive to replace

Raduino Features

This is a small board with an Si5351 clock generator, an Arduino Nano and a 16×2 LCD display. It plugs into the main radio board. The software that controls the radio is written in Arduino’s C langauge.

All the features are available implemented in Raduino software. The menus are accessible by pushing the button on the tuning encoder. You can add more features by hacking through the open source code available on https://github.com/afarhan/ubitx

  • Dual VFOs
  • RIT
  • Manual override of LSB/USB selection
  • CW Keyer Speed and tone selection

Check out the article published to the ARRL website. This article is going viral across various Facebook groups and pages, its good to see our local radio club and builders group in a positive light to the radio community. Many many thanks goes to the vision of L.A.R.C member Craig Thibodeaux, KM4YEC. Craig has worked diligently with the help of other club members, especially Dan W4DOD,  they have developed a consistent plan of advancement in the Bitx-40 project build, which puts a low cost 40 meter SSB radio in operation for qrp communications. The builders club is openingly sharing this process. Come join the builders group at the next build session on Nov. 18th. 2017, 2:00 P.M, at the  Jefferson City Library, Jefferson City, TN. The group is known as the WE Can Hams Builders Group, website is www.wecanhams.com.

Thanks to the builders, and Radio Shack’s willingness to partner with LARC. Many joint projects are being planned out for the local community.

Lakeway Amateur Radio Club puts ARRL Handbook for Radio Communications on Jeff City Library Shelf

Recently, Lakeway Amateur Radio Club – Builder’s Group, was searching for an additional meeting space for its group building sessions. After looking at the new library in Jefferson City it was discovered that there were no Amateur Radio books on the shelf.

Jefferson City Library Director – Anjanae Brueland with new ARRL 2016 Handbook for Radio Communications.


So, a careful preflight inspection was done: Large Conference Room seats 100 at capacity.

Full multi-media facility with wifi, computers, projector, drop down large media screen, sound system.  They even let us solder our radio kits (when we are very careful).

We even found a large back porch with really comfortable reading chairs, under the large ceiling fans, and as you can see: the back porch is shaded in the afternoon.

So, shaded in the afternoon in summer, and a large fireplace for the winter? So, for reading or operating radios or soldering on the back porch during a Builders Group Session, this venue is hard to beat.

So, Lakeway Amateur Radio Club – Builders Group – WeCanHams at work, assembling a HF (High Frequency) 40 Meter Band – 7 MHz kit Radio at one of our 3rd Saturday of each month Building Sessions.  Whether you call it a Builders Group, Homebrewing, Makers, Tinkering, Hacking, or just having fun, the Jefferson City Library is where its at!

And don’t forget the back porch, whether you curl up with your favorite book (maybe that ARRL Handbook) or join the Builders Group (WeCanHams.com) for some afternoon relaxation.

Many Thanks to Jefferson City Library and its very helpful and friendly staff.

Happy Hams and Happy Librarians. Library Director – Anjanae Brueland on the left and Library Assistant – Alexa Lee on the right, holding up ARRL Handbook from Lakeway Amateur Radio Club.
