    Very interested to get into a discussion about Hartely oscillators, Amplitude and Frequency modulation.
    Also interested to know how a 5 watt paraset radio transciever could be used by the Special Operations Executive in ww2 to transmit radio signals at just a bit up from 500kHz from, say, Paris to London. Isn’t that a long way for 5 watts ?

    This is an excellent collection of questions. However, the post may mislead some into believing that the difference between potential difference and electromotive force is whether a battery is involved.
