[Tlf-devel] choppy sound solved

[W.R. Juergens (DL2WRJ)]

Hello Joop,
I made a very short change and the choppy sound is totally gone. It 
sounds really good here, with a weight value set to 3. It sounds like 
the K2 keying with a value set to 1.10 (in the K2 menu).

In file cwlib.c change the 1000 for the weigthing to 3000 thats all ;-)
Please see my snippet below.

In the manual of cwdaemon is also a small failure, the value for weight 
is only -5 - +5 not -50 - +50.

No other problems detect during my testing.
