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,

I have made a couple of modifications which I hope will work, these are to include input LPF 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.

BARSICLE 2. Arduino Nano

CODE

// BLINK

void setup() {
  pinMode(13, OUTPUT);        // set pin 13 as an output
}

void loop() {
  digitalWrite(13, LOW);      // pin 13 LOW
  delay(1000);                // wait 1 sec
  digitalWrite(13, HIGH);     // set pin 13 HIGH
  delay(1000);                // wait 1 sec
}

// BLINK 1

#define LED 13

void setup() {
  pinMode(LED, OUTPUT);        // set pin LED as an output
}

void loop() {
  flash(100);                  // timings
  flash(100);

  flash(1000);
}

void flash(int t) {
  digitalWrite(LED, LOW);     // pin LED LOW
  delay(t);                   // wait t (ms)
  digitalWrite(LED, HIGH);    // set pin LED HIGH
  delay(t);                   // wait t (ms)
}

// VOLTS
// measure +5V output, mine was 4.62

float volts;                                          // ADC voltage read

void setup() {
  Serial.begin(9600);                                 // start serial comms
}

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