[SFDXA] CW in Ham Radio

[Pete Rimmel N8PR]

Kai,

My Icom 7600 does not need a computer to do RTTY or PSK31 It will send and 
receive both with a mini keyboard attached, not much larger than a paddle.

Hi Bill,
That's a great article with good reliance on reliable numbers, but it
misses a critically key point about technical performance. That is, CW
outperforms SSB by around  17 dB --  a power ratio of 50!  This means CW
can potentially talk 5 to 6 times as far as SSB.  Out of the three modes
that DXpeditions favor (CW, RTTY, SSB) it provides the best range. It is
around 3-7 dB better than RTTY.

It is also the ONLY digital mode that can be done with just a radio and
with no additional computer.

CW is not going away too soon!
