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

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.
Mr. W4KEV, Kevin Duplantis will be the guest speaker and will present a program for Lakeway members and visitors at the L.A.R.C. meeting this month on Thursday Oct. 26th, 2017 at the Youth Building First Baptist Church, Morristown, TN.
Meeting starts at 7:00 PM be there early to get your seat!
Come join us for an interesting program at our September’s meeting at the Jefferson City Library. September 28th, 2017.
we’ll be covering details of equipment used, software, antennas, computers, why it’s helpful, ways to use it! Get ready for another tools to use with Amateur Radio
WSPR (pronounced “whisper”) stands for “Weak Signal Propagation Reporter”. It is a computer program used for weak-signal radio communication between amateur radio operators. The program was initially written by Joe Taylor, K1JT, but is now open source and is developed by a small team. The program is designed for sending and receiving low-power transmissions to test propagation paths on the MF and HF bands.
WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions. Transmissions carry a station’s callsign, Maidenhead grid locator, and transmitter power in dBm. The program can decode signals with S/N as low as -28 dB in a 2500 Hz bandwidth. Stations with internet access can automatically upload their reception reports to a central database called WSPRnet, which includes a mapping facility.

The Tennessee Phone Net on 3980 was wiped out this morning by this solar event.
Early this morning (Sept. 6), the sun released two powerful solar flares — the second was the most powerful in more than a decade.
At 5:10 a.m. EDT (0910 GMT), an X-class solar flare — the most powerful sun-storm category — blasted from a large sunspot on the sun’s surface. That flare was the strongest since 2015, at X2.2, but it was dwarfed just 3 hours later, at 8:02 a.m. EDT (1202 GMT), by an X9.3 flare, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC). The last X9 flare occurred in 2006 (coming in at X9.0).
According to SWPC, the flares resulted in radio blackouts: high-frequency radio experienced a “wide area of blackouts, loss of contact for up to an hour over [the] sunlit side of Earth,” and low frequency communication, used in navigation, was degraded for an hour.
