There was a time, back inthe 1920s and 1930s, that any active device
(valves in them thar days, tubes for the leftpondians) would cost nearly
a week's wages for the average working man, and so it was good economical
sense to try and use it as many ways as possible simultaneously.

Times have changes, and active devices with performance into the tens
of MegaHertz are now ten-a-penny, so what is achieved by competitions
such as the "Two Transistor Challenge" where it is the costs of switching
(manual, relays) which would be the major outlay?

Not carping, just curious.

BUT BUT BUT, this one has no switching, apart from the Morse Key! ...

And the diode + FET! But I agree, counting transistors when capacitors
and coils can cost much more in both money and space has been
meaningless for about fifty years. Remember really advanced seven
transistor radios?

I had a Sinclair Micro 6, that was how I discovered Top Band (160m)
