The receiver circuit does not have an analog headphone amplifier - a digital output with pulse width modulation (PWM) is used. The audio signal is strong enough, even a small speaker with an impedance of 8 ohms can be used.. A Software Defined Radio (SDR) is a radio which has been designed to allow some, or all, of the traditional functionality of a radio to be handled in software/firmware on a computer, rather than in hardware. • Note that SDR does not mean control of a radio using software • SDR means the implementation of a radio in firmware or software. There are some old designs that use dual parallel tuned "tank" circuits which look like they might be able to do what I want. Each tuned circuit is a bit like a loop antenna with a large resonator and a smaller sort of "gamma match" ing segment the two are inductively coupled (what else) and nest inside of one another, sort of..
