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
