[RTTY] GRITTY

[Jim W7RY]

"They" said the same about CW, when the CW requirements for licenses are 
lifted, "NOBODY will be using CW". It's so old fashioned and slow!


Ever listen on a CW contest weekend?

I rest my case.

No problem there Bill.  I'm afraid you may get your wish.  There is a new
error correcting mode that is going to take over RTTY - and it's coming to a
band near you soon!   It's called Pactor 4.

REPLY:

Or better yet, when some smart programmer comes up with a replacement
for RTTY that uses Forward Error Correction (FEC) and is equally fast,
or nearly so. Then all these multiple decoders will be a thing of the
past, I hope.

There are plenty of FEC modes that ensure near perfect copy, but they
are painfully slow for contesting. There is one called Contestia but I
don't know of any contests using it so it hasn't really been evaluated
by many folks.  I have called CQ with it but never made a contact.

Dream on.
