[Elecraft] HW-16 Re: Latest Elecraft NEWS

[John Oppenheimer]

Took a look at Heath's HW-16 design. Quite ingenious: Using the PA
cathode bypass capacitors and current through a diode to shunt the
receiver front end during transmit. Early diode QSK operation. And a
neon bulb relaxation oscillator, using grid block keying voltage, for CW
sidetone.

I enjoy putting vintage stuff on the air for SKN. Heath did not
integrating their separates well back in the day, relying on 110V
antenna relays. I may have some DX-60A/HG-10B/HR-1680/HS-1681 ideas for
next year!
