[RTTY] MMTTY question

[w2up@mindspring.com (Barry )]

On 10m, which had zero background noise this weekend, a couple of 
very weak stations called me. I could hear the FSK audio fine, but no 
print. I turned off the squelch and moved the threshold all the way down 
in MMTTY, but still no print. Is there some other setting to adjust in this 
situation?
Tnx,
