Dick,

We ran a program called RITTY by Brian Beezley (K6STI). It had the best copy on RTTY ever. MMTTY is the only software that has come close in a windows environment. Unfortunately, it would require the use of a 16 bit Sound Blaster card (ct1670-?) That ran in an ISA slot. I was able to get the same results using a PCI slot and a 16 bit card. 
I still have the software and an old computer that could run  it but I would hate to have to dedicate the desk real estate. Although I admit, it would be a lot of fun to bring that back to life and see the software again.

Hi Rick,
 
I'm really interested in your concept of using a DOS computer for RTTY  
reception to improve "weak signal" reception.  My reception using  Windows XP, 
MMTTY, N1MMlogger and K-3 with 250hz or 400hz roofing filter is  rather 
poor.  When running my amplifier I am defintely an "Alligator"  as I hear dozens 
of stations calling during a contest that I can't  receive.
Some of this may be normal, such as when QRP stations with poor  antennas 
are calling.  But I'd sure like to maximize  my reception and plan to try 
your idea of using a DOS computer as  a RTTY Decoder.  
 
Question:  What DOS RTTY software are you running on that DOS  computer?
 
73,
Dick- K9OM
 
 
AS far as RITTY goes, I run audio to my PC and an old dos laptop using the  
internal sound card for RX only. I find 20-30% better copy on weak signals. 
I  remember at least 3 DXpeditions I could not have worked without it.   

Rick, N6PE
