Ham radio VFO with Arduino & AD8950

This is an VFO for use with old Ham Radio transceivers and with QRPs. I'm intending to use on the Ararinha-QRP-Triband project that I posted the PCB here.

It's a 10x10cm board with a nice all metal, no detent encoder from CTS.

I already ordered this PCB. I will work after the V1.0 on a smaller PCB so you can embedded the VFO or build a smaller radio. I will also add an option to connect the Encoder with a Header. That's can be a nice feature.

V1.0 PCB found bugs:

  • Inverted 78L05 regulator
  • Inverted LCD
  • Third Band pinout isn't on a GPIO pin! Only Analog Input. A cheap workaround is possible via CD4555B.

BASED ON http://py2ohh.w2c.com.br/trx/arduinovfo/arduinovfo.html PROJECT
