Obtaining the AA6YQ-FIR-512 Profile for MMTTY
The AA6YQ-FIR-512 Profile is optimized for weak signal decoding through the use of sharp filters. Sharp filters require more computation than broader filters, so expect an increased CPU load when using this profile.
If you are using WinWarbler and wish to gain access to this Profile, replace the USERPARA.INI file in your WinWarbler folder with the USERPARA.INI file in WinWarbler's Profiles folder, and then restart WinWarbler.
If you are using MMTTY standalone, or with another application that uses MMTTY as its RTTY engine, you can download a USERPARA.INI file that defines the following eight profiles:
- Standard RTTY
- Fluttered Signals
- Flutter Signals (FIR)
- 23 Hz RTTY (MMTTY)
- Multi-path
- hyper sensitive
- EU1SA
- AA6YQ-FIR-512
To obtain and use this file,
- terminate MMTTY
- in the folder that contains your MMTTY.EXE file, rename the existing USERPARA.INI file to USERPARA_ORIG.INI
download http://www.dxlabsuite.com/winwarbler/USERPARA.INI and save it into the folder that contains your MMTTY.EXE file
start MMTTY, open the Profile menu, and verify that the eight profiles listed above are available; then choose the one you wish to use.
Reverting to your Original USERPARA.INI file
If desired, you can revert to your original USERPARA.INI file by doing the following in the folder that contains your MMTTY.EXE file
- terminate MMTTY
- delete USERPARA.INI
- rename USERPARA_ORIG.INI to USERPARA.INI
- start MMTTY
Inserting the AA6YQ-FIR-512 Profile into an existing USERPARA.INI file
To insert the AA6YQ-FIR-512 Profile into your existing USERPARA.INI file, you can download its settings via http://www.dxlabsuite.com/winwarbler/AA6YQ-FIR-512.txt and use a text editor like Notepad to insert it into the USERPARA.INI file in the same folder that your MMTTY.EXE file lives. Standalone MMTTY is limited to 8 profiles, so you may have to remove a profile from your USERPARA.INI to make room for this one; if you have a profile named AA6YQ in your USERPARA.INI file, simply replace it with the AA6YQ-FIR-512 profile. Then restart MMTTY.
