AN HF HAM RADIO SSB/AM/FM/CW TRANSMITTER MADE FROM A RASPBERRY PI PICO AND NOT MUCH MORE

  Over on Hackaday we’ve seen a story about a Raspberry Pi Pico based software defined radio transmitter that is capable of transmitting SSB, AM, FM and CW anywhere between 0.5 – 30 MHz. The design generates an oscillator signal using the Pico’s Programmable IO. For AM/SSB it uses the PWM output pins to generate an RF…
