WinWarbler RTTY Settings

The RTTY tab provides settings that control operation when WinWarbler is sending and receiving RTTY via the soundcard using the MMTTY RTTY engine. (screenshot)

Changes to either of the settings in this panel will update the reverse checkboxes in the Main window's Receive and Transmit panels.

Settings on the AFSK and FSK sub-panels determine which form of modulation, which sideband, which transceiver mode, what frequency compensation, and what optimal offset is used during Soundcard RTTY operations:

LSB	configures WinWarbler for AFSK RTTY operation on the lower sideband selects the specified transceiver mode (if Commander is running and soundcard RTTY is active, switches the transceiver to the specified mode) directs the MMTTY engine to generate AFSK via the soundcard sets the external modem's RTTY modulation setting to lower sideband (so that if simultaneous soundcard RTTY and external RTTY modem operation is utilized, both mechanisms use the same sideband) transmit tones can be reversed
USB	configures WinWarbler for AFSK RTTY operation on the upper sideband selects the specified transceiver mode (if Commander is running and soundcard RTTY is active, switches the transceiver to the specified mode) directs the MMTTY engine to generate AFSK via the soundcard sets the external modem's RTTY modulation setting to upper sideband (so that if simultaneous soundcard RTTY and external RTTY modem operation is utilized, both mechanisms use the same sideband) transmit tones can be reversed
Xcvr Mode	the transceiver mode to be used for AFSK RTTY operation
Mark Offset	an offset (in Hertz) that aligns the displayed RTTY receive frequency with a known mark frequency when operating in AFSK mode; negative values are accepted. This can be used to compensate for an offset between your transceiver's VFO display and its actual frequency.
Optimal Offset	specifies the optimal receive offset frequency (in Hertz) when you click the Def button, the Mark and Space frequencies are set based on the specified optimal offset when you click the Opt button, the transceiver is QSY'd so that optimal receive offset falls midway between the mark and space frequencies

LSB

configures WinWarbler for FSK RTTY operation on the lower sideband
selects the specified transceiver mode (if Commander is running and soundcard RTTY is active, switches the transceiver to the specified mode)
directs the MMTTY engine to generate FSK via the port specified by the FSK Control
sets the external modem's RTTY modulation setting to lower sideband (so that if simultaneous soundcard RTTY and external RTTY modem operation is utilized, both mechanisms use the same sideband)
transmit tones cannot be reversed

USB

configures WinWarbler for FSK RTTY operation on the upper sideband
selects the specified transceiver mode (if Commander is running and soundcard RTTY is active, switches the transceiver to the specified mode)
directs the MMTTY engine to generate FSK via the port specified by the FSK Control
sets the external modem's RTTY modulation setting to upper sideband (so that if simultaneous soundcard RTTY and external RTTY modem operation is utilized, both mechanisms use the same sideband)
transmit tones cannot be reversed

Xcvr Mode

the transceiver mode to be used for AFSK RTTY operation

Mark Offset

offsets (in Hertz) that align the displayed RTTY receive frequency with a known mark frequency when operating in FSK LSB mode or FSK USB mode; negative values are accepted. These can be used to compensate for an offset between your transceiver's VFO display and its actual frequency. If your transceiver's VFO displays the RTTY mark frequency, then the correct value for this setting is -2125.

Optimal Offset

specifies the optimal receive offset frequency (in Hertz)

when you click the Def button, the Mark and Space frequencies are set based on the specified optimal offset
when you click the Opt button, the transceiver is QSY'd so that optimal receive offset falls midway between the mark and space frequencies

FSK Control

specifies the means by which FSK information is conveyed to the transceiver

None	no FSK information is conveyed
COM1-64	FSK information is conveyed via the specified serial port's TxD pins the selected serial port must be capable of operating at 45 baud (most USB-to-serial-port-adapters are not) selecting a serial port sets the PTT port to the same serial port
EXTFSK	FSK and PTT information is conveyed via the EXTFSK application, which communicates via a selected serial port or parallel port, but the parallel port can only be used on 32-bit versions of Windows
EXTFSK64	FSK and PTT information is conveyed via the EXTFSK64 application, which communicates via a selected serial port or parallel port has improved timing relative to EXTFSK supports speeds other than 45.45 baud the parallel port can be used on 32-bit and 64-bit versions of Windows
TINFYSK	FSK and PTT information is conveyed via the TinyFSK application, which communicates via USB
Update	when clicked, tis button repopulates the FSK Control selector and the FSK Control selectors on the MultiRadio Configuration window's RTTY tab with the above options and with the names of any other .FSK files present in WinWarbler's folder whose total filename length is 12 or less.

The FSK Control and the FSK Control selectors on the MultiRadio Configuration window's RTTY tab will also be populated with the names of any other .FSK files present in WinWarbler's folder whose total filename length is 12 or less. In a multi-radio configuration in which each radio requires a separate instance of EXTFSK64.FSK, a copy of EXTFSK64.FSK renamed EFSK64-2.FSK can be created in WinWarbler's folder; clicking the Update button will populate the FSK Control selectorss on RTTY tab tab of WinWarbler's MultiRadio Configuration window with both the EXTFSK-64 and EFSK64-2 options, permitting each to be selected for use by a different radio.

The RTTY and Soundcard tabs of WinWarbler's Configuration window provide control over the basic settings required to configure the MMTTY engine for RTTY operation. However, the MMTTY engine is controlled by settings that govern

Configuring these settings is accomplished by clicking the MMTTY Setup button on the Configuration window's RTTY tab, which displays MMTTY's 6-tab Setup window; the settings adjustable via these tabs are fully described in the MMTTY help file; some frequently-used settings are also described here. However, tweaking this many settings while trying to work BQ9P through the auroral flutter is clearly impractical, so MMTTY provides a Profile mechanism.

To simplify the task of managing many settings, MMTTY provides profiles; a profile is a named group of settings. You can save MMTTY's current settings to a profile, and later restore those settings by selecting that profile using the Profile Selector in the Main window's RTTY receive panel. You can define up to 16 profiles. To save MMTTY's current settings in a profile,

When WinWarbler starts up with its Operating Mode panel set to RTTY, or when the Operating Mode panel is changed to RTTY, the MMTTY's settings will be loaded from the profile specified in the Profile Selector in the Main window's RTTY receive panel unless the Profile Selector is set to

in which case MMTTY's settings will remain as they were during the last soundcard RTTY operating session.

Profiles are stored in the file named USERPARA.INI that resides in your WinWarbler folder.

WinWarbler provides a USERPARA.INI in its Profiles folder that contains 8 predefined profiles:

To gain access to the above profiles, copy USERPARA.INI from the WinWarbler/Profile sub-folder to the WinWarbler folder before starting WinWarbler.

Selecting a profile can change MMTTY's Unshift On Space, Reverse, and Keyboard Mode settings; you may need to modify these settings if they don't match your setup and/or preferences.

Note that controls in the MMTTY Setup dialog allow you to enable or disable Automatic Frequency Control and the Bandpass Filter. WinWarbler's AFC and BPF control boxes will not reflect changes made via the MMTTY Setup dialog until you click the MMTTY Setup dialog's OK button.

While the MMTTY Setup dialog provides control of settings otherwise not accessible from within WinWarbler, it also results in there being two different ways to specify some parameters, like the serial port used to control PTT. Making a change from either WinWarbler's Config window or MMTTY's Setup dialog will have the advertised effect, but its the WinWarbler settings that persist from one operating session to another.

If sub-band highlighting is enabled, the frequency scale above the tuning display is rendered in green for frequencies within RTTY sub-bands, and in red for frequencies outside of RTTY sub-bands. By default, RTTY sub-bands are defined by the contents of the file DefaultRTTYBands.txt in WinWarbler's Databases folder. Each line in this file defines the RTTY sub-band within a named band:

160M, 1.800, 2.000
80M, 3.500, 3.750
40M, 7.000, 7.150
30M, 10.100, 10.150
20M, 14.000, 14.150
17M, 18.068, 18.110
15M, 21.000, 21.200
12M, 24.890, 24.930
10M, 28.000, 28.300
6M, 50.100, 54.000
2M, 144.100, 148.000

To specify your own sub-bands, make a copy of DefaultRTTYBands.txt in the Databases folder and name it RTTYBands.txt. Edit the frequencies in RTTYBands.txt as desired, and save your changes; you can also define sub-bands for the 6M and 2M bands. In the Main window's Mode panel, select a mode other than RTTY, and then select RTTY. the tuning display's frequency scale will be colored as specified by your custom sub-band definitions.
