[LCC] 2Tone vs. MMTTY

[Mark, K5ER]

Don,
         Thanks for the thoughtful and detailed write-ups. Few of us would 
have the patience to capture and compare that many screen shots, and take 
detailed enough notes to sort them all out. Its obvious that you are 
passionate about this mode, and have always been willing to share your 
knowledge so others can experience the enjoyment. As a recent convert to 
RTTY, I am certainly enjoying it, but you sure are making me work!
         I had only this past year added a 2nd monitor to my shack 
computer. Its a good thing, since once I decided to jump on the rtty 
bandwagon, I was determined to do rtty SO2R, like I do the other modes. 
I've found that with big antenna, some signals are very strong, but 
consequently, those in the nulls are often very weak. I had many over the 
wpx rtty weekend that were difficult to copy, needing multiple times to get 
enough print to insure the right exchange. Its great to know that there is 
another decoder to use to enhance good copy. Looks like I need to install 
TWO copies on my logging computer,  but the 2nd screen is only just so big. 
so now I'll have to make the windows smaller. Can you recommend a good 
optometrist who might help me to SEE the good copy??
         All kidding aside, thanks for helping me get my FSK set up for 
so2r. Couldn't have done it w/o you pointing me in the right direction. Had 
several distractions over wpx rtty weekend, but I'm learning and having fun.

73,
Mark, K5ER
