Built TAURUS 40m SSB Exciter

As an advanced part of the BARSicle project the plan is to build RV3YF's TAURUS SSB Exciter and 5W PA.

I have received the kit for both, and so far built to SSB Exciter,

SSB EXciter

I have made a couple of modifications which I hope will work, these are to include input BPF for the VFO input of 4.0592 - 3.9592MHz (tuning 7.0 - 7.2MHz) and for the SSB filter input at LSB = 11.062MHz, USB = 11.056MHz. These signals will be provided by the VFO synthesiser using an Si5351, the third Si5351 output will be on 7.0-7.2MHz for our Direct Conversion RX.

float volts;                                          // ADC voltage read

void setup() {

}

void loop() {
  volts = analogRead(A0) * 4.62 / 1023;               // read ADC -> volts, "+5V" ref
  Serial.println(volts);                              // display on Monitor
  delay(100);

BARSICLE BASICS

This is an outline of the BARSicle project, to build a complete homebrew 40m SSB station. The aim is to build technical know how among club members, from beginenr to advanced levels - LEARN, CODE, BUILD.

It includes a course in coding for the Arduino microcontrollers
