[WT-support] R: R: WinKey for PTT in SSB ?

[Mikael Larsmark]

Hello

This is not at all true if you ask me. I have "never" seen any 
stuttering CW with N1MM or Writelog but with Win-Test I have been having 
huge problems through the years so nowadays I always use WinKey.

I think I've posted about this in the past and the reply has always been 
"Use Winkey".
