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
Morristown Hamfest Builders Fest on Jan 6, 2018, also see MiscDotGeek’s Multiband BitX40, and WB5YYM’s Expandable boards in his All Homebrew 40m Station- BitX40, and maybe take one home (BitX40) for Best in Show, Bring your Homebrew, W8TEE talking about Homebrewing, and sitting down at the Roundtable…see you there.
There is something behind that STOP sign, and at 1pm today it will be removed. Get Ready
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.
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.
Club President, Dale Knight AB4DK
