[RTTY] 2 tone vs MMTTY

[Don Hill AA5AU]

I have spent many hours comparing 2Tone and MMTTY. 2Tone is nearly always better especially on very weak signals. However, during
W1AW/5 the past week I noticed that when operating split and tuning the VFO to the next station, that MMTTY would start to print
before 2Tone. This is nearly exactly what happens when using a HAL DXP-38 vs. MMTTY while S&P in contesting. The DXP-38 would start
copying well before MMTTY when tuning onto a signal.

I had always thought this was because the DXP-38 (and now MMTTY when compared to 2Tone) had a "wider" front end. Not sure that makes
sense or not.

When tuning onto a signal, MMTTY starting printing well before 2Tone. Had it not been for this, I may have missed quite a few calls.

Just my observation.

BTW, I made 2556 RTTY contacts as W1AW/5 and it was a lot of fun. One observation is that running W1AW/5 was a lot easier than
contesting because you didn't have to catch the exchange, only the callsign. However, I tried SO2R while running split on both
radios and that is extremely hard so I only did it once. All the other times I concentrated on just one radio to make sure I got
everyone is the log. 

SO2R while running split on 2 radios is like S&P on two radios in contest. It's very hard.

During the W1AW/0 Colorado event a number of the guys reported that they felt 2 tone did a better job than MMTTY.

This all anecdotal.  I have been using both on and off and most time while chasing DX there seems to be no clear winner with my
operations.

The nice part is having another decode screen confirm that what you see is a good call etc.
