If you're interested in fiction about some of this, I highly recommend _The
Lost Flying Boat_ by Alan Sillitoe. This is fiction, but as a former radio
operator himself, and a fine writer, he communicates the magic of Morse very
nicely.
Thanks! I've not read that one.

Hello All,
The most incredible aviation story of all, is the round-the-world-flight of
the Pacific Clipper at the start of WWII. It is the subject of two books,
the first written by Pan Am Radio Officer Ed Dover:

The long-route airline aircraft of the era often had a radio operator on
board. He had to be licensed the same as a merchant marine radio officer,

I used to copy press off the air in the 50's. As the lone Flight Test ground
controller for Lockheed Aircraft Service, it helped fill in the time between
condition checks with planes aloft and preparing meteorological reports. We
used both HF AM and CW in those days. The press was sent from

Hi Ron,
Coast Station WCC in the 1970s sent a nightly news/sports/financial
broadcast in the 1970s at somewhere around 30 wpm. It was great practice,

Ron and all,
Are you aware that reducing the RF gain will reduce the AGC action as well.
Folks who want to try it may be surprised how well copy can be made under
QRM conditions with the AF gain at full and the overall gain controlled by
the RF gain.
With this technique, the residual AGC

Well, YMMV ... but I'm sort of with Ron. I like to know what's going on
around me, and if I want to really dig in and pull someone out of the
noise, I know I can do it (well, sometimes!). I retired from
communications engineering, and I accept all the theory for channels
subjected to noise and
