A number of people have brought me information about MT-63, both pro and con.
Officially, PWCARES will use the mode that works best for us and we are currently evaluating the various modes that are available to us. MT-63 is just a starting point, because you have to start somewhere.
MT-63 2KL was chosen because it is the NBEMS standard adopted by the ARRL. And it was a good place to start.
Here is only one of the arguments against:
- nice for file transfer but not so good at keyboard typing (errors creep in).
- The Army uses both MT-63 1KL and 2KL as their go to backup mode when MS-110A doesn’t work due to atmospheric conditions.
There are as many opinions and positions as there are amateurs. If someone has a definitive or quantitative analysis, please feel free to post it in the comments or send it directly and I will add it. At this point, we will all keep an open mind.
