JT65 encodes 72 information bits including full calls and the 
locator. You cannot reduce this number of bits. Furthermore, 
all operators must use a CALL3.txt with identical locators.

Things are continuously changing. "Problems" are solved or 
they dissipate and new ones originate. Hopefully, there will 
be a necessity of discussion for ever. It is part of our 
wonderful hobby. 

I have a computer program in advanced stage of construction 
that generates and decodes CW for EME-work. The transmitted 
CW can be read by ear, but CW signals generated other than 
by my program cannot be read by this program. So this CW is 
purely digital. It would not be allowed to use it within a 
CW contest. Very funny, you are right:

Thanks Marius, and 73 to all
