Oct 1, 2024. So, what is wrong with this photo?

  This is the current display on the P3ST QRP SSB Transceiver which shows a lot of info on a 128X160 small sized screen. It is of the ST7735 form of Display. What is presented are two VFOs (A &B) that have VFO memory, but also a much smaller display of the VFO frequencies with a thought of split operation. The simulated Green LED's signal what is "hot".  The initial theory was that you could receive on the A VFO but actually transmit on the B VFO. While the logic exists in the sketch, it was never actually implemented. Albeit you can switch the VFOs with a panel switch but not split operation. We also have the Step Tuning rate and the S Meter which by the way is implemented using an audio sample. I included my call sign just in case I forget and the title under the A VFO directs me to the Arduino sketch in the Arduino directory. Lest I forget we show which sideband is selected with a simulated RED LED.   Needless to say, it took many hours of programming to get this d
