[LCC] CQ WW RTTY

[George- K4GM]

Mark,

Welcome to RTTY.  It's a blast.  I had never touched RTTY until 2006 and 
was instantly hooked. I think I worked you on two bands from NR4M a 
M/M.  We use N1MM and added a second window for decoding using 2Tone by 
G3YYD as the decoder in window #2. Wow! What a difference over MMTTY. I 
cannot count how many times the MMTTY window would have gibberish or 
absolutely zilch while the 2Tone window would show a full call verified 
in the call check window.  However, there were a few times when MMTTY 
decoded better but not many.  About half way through the contest I made 
2Tone my primary window and MMTTY secondary. 2Tone seemes to have it all 
over MMTTY on weak signals or ones with heavy QSB.  Hope to see you in 
the next one.

73, George, K4GM
