2018 ~ The Year of SSB Transceivers

6/21/2018 ~ 6 and/or 4 Meters Your Band?





Yes you are reading that the displays are saying 6 meters or 4 Meters. There are many possibilities with the Arduino and Si5351. These are but just a couple examples. No, the 6 or 4 Meter hardware is not built but if you have such rigs and need a sketch email me n6qwham@gmail.com


6/18/2018 ~ More Possibilities






The code has been ported over to the Color Touch Screen and the 160X128 Color TFT. Lots of possibilities!

No Flickering of the Display !~ Thanks DuWayne KV4QB!


6/16/2018 ~ Two VFO Code: 160X128 TFT


Follow the link and look for the Simpleceiver project. There you will find a link to the code where the code is a notepad document. Copy and paste into an Arduino sketch. Note below:



  • The sketch is made with Arduino IDE 1.8.5
  • The display is a 160 X 128 Color TFT
  • You must have all of the libraries in your Arduino directory for this to work
  • You must also have the "included files" in the project folder for the sketch to include Rotary.h, Rotary.cpp, si5351.h and si5351.cpp. You can find these files under the Bitx40 link (on the website)  and these too are in notepad form.
  • This is provided for you as a roadmap of what I did. Quite honestly --it works for me but I am not an Arduino expert --simply a Radio Genius. 
  • Do not take me to task for not having elegant code -- I will leave that to you EMRFD and uBitx illuminati. But what is shown is a workable two VFO rig. If I knew what I was doing the code task would have been a lot easier -- but the bottom line I have it working on three different types of displays. By and large the Touch Screen was the easiest to implement 
  • Opening the connection that is made to Pin D4 (with another 1N4148 in line with the wiring with the Cathode connected to the PTT connection) will provide a functionality of independently transmitting/receiving on either VFO A or VFO B. So now the options are 1) Transmitting/Receiving on VFO A, 2) Transmitting/Receiving on VFO A but independent receive on VFO B and 3) Independent Transmitting/Receiving on either VFO A or VFO B. However some of the display status info would not be available with option 3 -- but the rig will operate normally. I may internally mount a switch inside the box so I could engage option 3.
  • You will need one external relay connected in series with the switch that selects VFO A or VFO B. This relay is opened during transmit so that while you can receive on either A or B you will transmit on VFO A. The relay coil is energized off of Pin D7. The relay is a 5 VDC unit with a 178 Ohm coil --doing the math (E = IR) that means the current draw is 28 Ma. The max current draw form an Arduino pin is 40 Ma.
  • I received a "concern inquiry" as to the relay coil connected directly to an Arduino pin. While I did not previously mention this, I have a 1N4148 "Snubber Diode" connected across the relay coil with the cathode connected to the Arduino Pin.  (Pin D7)

  2. Nice job Pete, hopefully one day the USA will get a 70MHz allocation, it is a prime VHF band for possible transatlantic comms.
    Not much progress here in Blighty with the projects, got my fingers in many pies with work commitments so just reading and researching until things settle down.

    Cheers and 73

    1. Hi Rob,

      Yes I think 70 MHz would be nice as the antenna requirements are modest and therefore a multi-element high gain beam would have a small foot print. But I am sure Ajit Pai our head FCC commissioner can't see a way of making any money from such an allocation so it is not even on the radar. It is a shame when money is the driver not the idea of technology advancement.

    2. I know that the WG2XPN 70MHz beacon as trialed a few years ago, not sure if it still gets the annual NoV however I used to leave WSJT on 70.005MHz running whilst I was at work in hope of snaring it during the multi-hop Es openings.

  3. Pete, what rtx will we use with new display with double vfo s 😁😁😛

    1. The new display actually it is a 160 X128 and can be used with any transceiver. I finally decoded how to do double VFO's. If you look on www.n6qw.com you will see the Simpleceiver Plus with the two VFO's

    2. Yes,Pete...of course but i dont know where i can put t this new lcd 😁😛
