[Elecraft] Farnsworth and EME

[Ken_ke2n]

Why wouldn't you just QSZ? That's the time-tested method of getting Morse
through during weak/fading sig cdx. <unquote>

Believe me, repetition of the call signs is done in the extreme in EME.

Each time, the listener tries to keep track of what he *thinks* he heard and
eventually builds up a best guess at the call sign. I typically send my call
6 times twice over in an exchange.

One thing that is usually NOT done is sending slowly (QRS). This is because
the fading punches holes in the middle of long characters. A "J" becomes "A"
"T" for example.

So you send  around 15 WPM, trying to get a whole character through between
fades. It becomes important to know if you have heard two characters, or one
with a hole in the middle. Hence the use of exaggerated character spacing
(a.k.a. Farnsworth).
