The Digital Interface - Window

The Digital Interface window used is for each type of interface (MMTTY, MMVARI or an external interface) and is for all very similar. 

The Digital Interface is shown when it is selected under Window in the Entry Window. If a second RTTY port is configured a menu item will appear on the top of the Digital Interface allowing you to open the second RTTY interface.. The exact frequency is displayed in Digital Interface caption (rig(+/-)audio).

• TX - Indicator to show where the transmit is going to take place (useful when using two sessions like SO2R).
• Letters/Figs - Shows where is mouse is on in reverse (letters/figures switched).
• MouseOver - Shows the text which would be selected where the mouse is positioned over.

• Top RX window - This is the receive window. This is the window used for making QSOs. There are 2 ways of placing a callsign into the callsign window of the logger you can single click on a callsign and it will transfer over to the main logging window. Whenever a callsign is printed to a window followed by a space it will be sent to the callsign grab window for easy movement to the logging window by clicking the Grab button. Also in the window if the LTRS/FIGS Converter is turned on a Text line will appear at the top of the RX window. When the LTRS/FIGS Converter is turned on moving the mouse over text in the window will show the converted text in the Converter text line.
  By clicking on the colored pane on the left you can pause input to the receive window to scroll back through the (last 2000 lines of) text using the scroll bars. When the window is paused the color of the pane will turn Yellow. To turn input to the window back on click in the pane again and everything that was to be printed to the window will now enter the window. When the receive window is paused it is possible to copy text in the window.
• Bottom TX window -This is the transmit window, a free form typing window. If you click on the TX button the cursor will be placed into this window and what ever is typed will be sent. The size is static and doesn't change size (2 lines).
  Only for TNC users. When not transmitting, anything typed in the TX Window will be sent to the TNC. Used to change settings etc.
• Callsign Textbox and Grab - When a callsign is encountered in one of the receive windows (starting and followed by a space) it will be placed in this textbox and when you press the Grab button it will transfer the callsign over to the main logger window. The grab callsign window holds the last 10 callsigns seen in the RX window. The most current one is at the top and is highlighted. Dupe callsigns will not be shown in the grab window.

  Note: If the callsign in the callsign field in the Entry window is equal to the callsign in the received text, the call in the Entry window does not get placed into the grab call list.

• Macro buttons - These buttons on the Digital Interface are (max.) 24 extra macro buttons for preprogrammed messages. Configuring these macro buttons is done in the Digital Interface window under 'Setup | Settings' or by right clicking on them which brings up the Digital setup dialog. The macro buttons widths dynamically adjusts in relation to the width of interface.
• Clr RX - Clear the receive window (also possible using the right click menu).
• Align - This is used to move the signal that you are coping into the pass band of your filters. Set the frequency in the setup area.
  Example: center of filter pass band is 2100. When clicking on a signal at about 1400 it will be a hard time coping him. In order to copy the station has to come in my filter range. Click Align and the rig shifts and the spectrum frequency shifts and places the station on the set frequency setup already. Now click a button to turn on the filters and poof there he is...
• TX - Start the RTTY transmission, the transceiver is keyed. This button is only shown when MMTTY is selected.
• RX - Stop the RTTY transmission, the transceiver changes back to receive. This button is only shown when MMTTY is selected.
• Grab - Transfer the selected callsign in the Callsign textbox to the callsign field on the main logger window. Once the callsign is filled what ever you click on next will fill the next box to have info entered in. The mouse is the only way to do this.  When the Digital Interface is in transmit calls are not added to the Grab window.

It is possible to have 2 Digital Interface windows open at the same time. Open your first interface then click again on the menu item called 'Open 2nd RTTY Window'. This feature can be used to copy both the TNC and MMTTY to pick up on callsigns you might have missed etc. Or if you have 2 radios and 2 separate TNC's you can switch between the 2 of them. Note: The macros for the second Interface window you open up will not be the same as they are for the first window you open.

Callsign coloring

When a callsign is recognized in the receive input stream and the callsign is found in the Master.dta file the callsign will be colored and brought to the Grab window. When 2 calls are found in the same String the last one gets highlighted. The highlighted calls in text strings are clickable.

Mouse Assignments

The Digital Interface - Setup

This setup dialog is for both MMTTY and MMVARI, this means that some settings are only for MMVARI, MMTTY or both. When selecting 'Setup | Settings' in the Digital Interface window a dialog like the one below will shown.  Any changes made in the setup form must be saved by clicking the Save Configuration Button located on the bottom of the form. Any changes made and saved will be changed as soon as the setup area closes.

Tab: General/MMTTY Setup

• Use Auto TRX Offset in DI1 - Adds or subtracts the Mark frequency to the radio frequency and adjusts the band maps accordingly for Digital Interface 2.
• When setup correct  packet spots actually show up where they are posted. Say for example you are using AFSK and someone posts a spot at 14.080 when you click on that sport the radio will go there but you are actually listening 2.125 hz further up or down the band so you always have to chase the spot. by turning this on when you click the spot it will adjust the radio to where it should be so the spot still lines up on 14.080 but you mark freq will be on that spot instead of the radio.
• Use Auto TRX Offset in DI2 - See above, but for Digital Interface 2.
• Add Callsign to Bandmap on Alt+G - (MMTTY and PSK) Option to send callsign from station in callsign field (Alt+O) when doing a grab (Alt+G)
• Send Space on Using Grab - Setting for sending space after grabbing call from grab window.
• Send Space on Callsign Mouse Click - (MMTTY and PSK) Ability to set if a space character is sent to Entry Window when clicking on the callsign with mouse. Select to enable.

• (MMTTY-MMVARI) Turn AFC Off when switching to S&P - (MMTTY and PSK) Ability to Turn AFC Off (MMTTY-PSK) when going from Run to S&P. Select to enable. Many people when in Running mode  will leave the Net Off and turn on AFC to find people coming back to them a little off frequency. So to turn the AFC back off when you go to S&P (without forgetting) this setting comes in handy.
• Do Not add Dupes to Grab Window - Setting for adding dupes to Grab window or Not.
• Remove Excess Linefeeds from RX Window - Ability to strip excess linefeeds from RX Window.

• (MMVARI) Do not send Squelch tail - (PSK only) Ability to not send squelch tail in PSK mode which gives a faster turn over time. Select to enable.
