[CQ-Contest] ARRL to allow self-spotting in contests

[David Gilbert]

Here's how:

CW transmission from a keyboard macro (just like almost ALL contest 
exchanges use) but pre-encoded with FEC, LPDC, etc and sent in short 
bursts (maybe 5 seconds?) with a bandwidth on the order of 200 Hz. Not 
many CW transmissions, even in a contest, are faster than that.

Transmissions received and decoded using the same DSP techniques as for 
FT8, but converted to audible CW instead of being displayed as text.


There are no straws being grasped here.  Just expressions of frustration 
that FT8 has mentally corralled all use of these signal enhancement 
techniques.

73,
Dave   AB7E
