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.
