As I alluded to earlier, transmissor est omnis divisus in partes tres, the oscillator, amplifier and filter/antenna system, worked on by three student groups.Now, we want to engage the reverse beacon network to test range, so this student decided to try and key "TEST..." automatically.We'll probably let the mcu switch an PNP-NPN transistor combo to key the Vcc direcly and see how that goes.#hamradio
