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 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).
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.
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
We’re quite excited to announce that MiscDotGeek is co-sponsoring Builders Fest 2018! What, you haven’t heard about Builders Fest 2018? The first annual Builders Fest is going to be at the Lakeway Amateur Radio Club’s 26th Annual Morristown HAMFEST, Saturday, January 6th, 2018.
The Builders Fest is the brainchild of Craig Thibodeaux, KM4YEC. Craig has partnered with a local Radio Shack whose franchise owner is focused on bringing back the core values of the Radio Shack of days gone by. They’re offering Licensing classes, soldering classes and more. They along with a few others, are sponsoring the Builders Fest 2018.
On the speakers list is Jack Purdum, W8TEE. He’ll be bringing along a certain SSB QRP transceiver, but more on that in a moment. Be sure to scroll down to find out more!
Randell Curtis WB5YYM will be displaying some of his epic builds. He’s known for the gorgeous hand built cases which hold equally excellent equipment. His BITX40 and and 49er builds are as functional as they are great looking. Also at the fest will be his dual IFR-510 amplifier.
You’ll be bound to come away with ideas and inspiration for your next build, whether it be from scratch or from a kit- or in Randell’s case- both!
Craig Thibodeaux KM4YEC will be displaying his BITX40 build as well, and you’ll get a chance to see a great portable configuration suitable for just about any setting.
Of course I’ll be there in spirit, as the Multi-Band BITX40 will be on display along with the QRP Labs goodies that make the conversion possible. You’ll get to see all the bad soldering, battle scars and hot glue that holds this thing together. Trust me, if I can do it, anyone can do it. Come check it out!
Along with these builds will be a mover and shaker in the Ham Radio community, Jack Purdum W8TEE! He’ll be presenting a talk, and will autograph ‘Arduino Projects for Amateur Radio’ and his other books, magazine articles, 49er project from QST in 2016, and his Antenna Analyzer in Nov QST 2017, and others.
Jack will be displaying and demonstrating his Forty-9er, dummy load/wattmeter, frequency counter and…
He’s also brought along a special treat for the QRP/Builder community- the highly anticipated hfsigs.com uBITX kit! This thing isn’t even out yet, but he’s managed to get his hands one one just the same. Rumor has it that you’ll be able to see the uBITX in action.
Many thanks to the sponsors and co-sponsors of the Builders Fest. You’ll have a blast if you can attend, and there are bound to be some QRP related door prizes- a BITX40, and perhaps some QRP accessories? We’ll see! Check out http://www.morristownhamfest.com/ for all the details and schedules. 73!

Lakeway Amateur Radio Club Builders Group
The purpose of this group is to foster and accommodate the art of DIY in Ham Radio. The group is available to new and experienced hams in the Lakeway Area in East Tennessee. Projects vary from simple antenna construction to projects using
microprocessors such as the PIC and Arduino.
Oldest Ham F8IL, SK
Jean Touzot, F8IL, of Albi, France — said to have been the world’s oldest radio amateur — has died. The “dean of French radio amateurs,” Touzot was 109 and enjoyed operating CW with an old-fashioned hand key and a modern Yaesu transceiver. He “retired from the airwaves for health reasons” at age 105 in 2014, according to media accounts. Until then he had been active on the air, making daily contacts on 80-meter CW with other stations in France. In stepping back from his ham activity, Touzot said he no longer was able to send CW and made “too many mistakes.”
He was a member of France’s International Amateur Radio Union member-society REF as well as of the Union of French Telegraphists (UFT).
Born in Algeria, Touzot had been on the air since 1936 and had learned CW in 2 months during his time in the military. Prior to military service, he attended the Technical Institute of Toulouse and became an industrial designer, retiring in 1966.
Touzot received considerable acclaim in 2009, when he became a centenarian. Among his gifts was a special Morse key created especially for him.
No official records are kept to document who is the oldest radio amateur.
