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:

I was at VO2AAA in Labrador City for CQ WW CW with K2/100 #850 and an
AL-1200. We were next to a residential area with a very high line noise
and precipitation static.
On 80 and 160 meters with the AF gain about 3/4 way up and riding the RF
gain and DSP with noise reduction made some of the

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

The press was sent from punched paper tape, I believe. It ran

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,
and interesting too.

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
From time to time I make a post reminding folks that there's a web site where
the content comes from a submarine radio operator (www.zerobeat.net/submarine)
.
I'd love to do a similar site with the memories and stories of folks who made
their living pounding brass, whether aboard ship, at a
