See the Spreadsheet mentioned in the message below. MMTTY provides two
different RTTY demodulators: PLL and Frequency Discriminator. The Frequency
Discriminator can be configured to use two different kinds of digital
filters (IIR, FIR). A Profile lets you choose and configure the RTTY
demodulator, as well as establish other settings used during RTTY operation.
To better understand the parameters listed in the spreadsheet, open MMTTY's
Help, select the "Demodulators" topic (near the bottom of the Table of
Contents), and review the material there.

Subject: RE: [RTTY] EU1SA Profile?
EU1SA's profile uses an IIR demodulator like the Standard RTTY profile, but
with sharper filters (which increases the CPU load).
I've uploaded a USERPARA.INI file that includes the "EU1SA" profile along
with "Standard RTTY", "Fluttered Signals", "Fluttered Signals (FIR)", "23Hz
RTTY", and "MultiPath" to
www.dxlabsuite.com/winwarbler/Profiles/UserPara.ini
If you've created new profiles or modified the existing profiles, then save
your current UserPara.ini file before replacing it with the above. Then
start MMTTY, open the Profiles menu, and choose EU1SA. You can define up to
8 profiles in UserPara.ini, so you can replace the one's you don't like with
ones you've developed or modified.
Documentation for the parameters that can be set in a profile is available
via
www.dxlabsuite.com/winwarbler/Profiles/UserPara.doc
A spreadsheet comparing each of the profiles (including EU1SA) to the
"Standard RTTY" profile is available via
www.dxlabsuite.com/winwarbler/Profiles/Profiles.xls

Can someone point me (and maybe some others) to info regarding these
specific profiles such as EU1SA? I did various searches, checked MMTTY
profiles and help files and didn't come up with anything that got me
relevant results specific to EU1SA.
Thanks in advance!
