- That's true. Neither the RSGB or the ARRL pointed out how unacceptable transmitter (and receiver) performance is in that radio. But we are making progress, the ARRL is now including closespaced bloc

- This is a little off topic but its for research ultimately in amplifiers. How many older receivers or transceivers, preferably tube type had the mixer circuits grid driven by the oscillators? I know

- and off the mixer tube it does become a very effective >frequency mixer. It then appears to be an analog mixer multiplying a signal with a square wave. It does reduce the conversion gain, though. Tha

- Will, Applying signal and oscillator to g1 is, as you say, an old technique. It had problems when the oscillator is a long way from the signal frequency, in that the input tuned circuit attenuates th
