And in the early versions, impedance coupling to the headphones. As I say on my website, I 
have seen at least 6 different, and I mean significantly different, schematics for the Paraset. 
Another problem with the receiver is that there is no possibility for monitoring of one's own

What I found most interesting about the transmitter was the very extensive capability for 
matching almost any antenna load.

On the other hand, I never liked using any sort of "beam tube" as an oscillator.
