[RTTY] HAL ST-8000 and 6000 vs. Sound Cards

[Neal Campbell and Sarah Ferrell]

I ran MMTTY, RITTY and a ST-8000 simultaneously a couple of years ago 
in the CQ WW RTTY test. I did not find a clear winner. I think because 
of its ubiquitous installation, MMTTY is the best choice for almost 
everyone. Works on all windows sound cards, XP,98se,95, etc. I think it 
was slightly more accurate most of the time. RITTY also is a top 
performer but the configuration issues (no NT-based OSs, ISA sound 
cards, etc.) make it more difficult, that plus it costs money. The 
ST-8000 actually copied better than I had guessed prior to the test.

As I believe in Don's recommendation to have a couple of different 
modem types for diversity, I would tend to take a soundcard-based modem 
(MMTTY or RITTY) and a hardware based one (I have ST-8000, AEA PK-900, 
etc.) Its a tweak, not a requirement for entry into the big leagues 
though.

My view, load up MMTTY, play in a few tests, if you feel you are really 
missing something, borrow something else and run them in parallel.
