Digital Setup

1. Setup Overview

Setting up an interface involves configuring the Logger for the selected interface. Configuring has to be done within N1MM logger in a few places, including the Configurer as well as the Digital Interface window. If you are using MMTTY for FSK RTTY, you will also have to perform some configuration from within MMTTY. If you use Fldigi, there is some configuration that must be done from within Fldigi.

Before you can use MMTTY, you will have to download and install it. Likewise, before you can use Fldigi, you will have to download and install it. This process is described in the next two sub-sections. You do not need to download or install any additional files or programs to use MMVARI or a TU/TNC.

A brief note about hardware connections for sound card digital modes (using MMTTY, MMVARI or Fldigi). These depend on the radio, the sound card and the interface (if any) in use, and it is impossible to cover all of the possibilities in detail, but the following general comments apply.

First, you must have some means of connecting the radio's audio output to the sound card's input. The ideal connection would be from a fixed-level ("line out") output on the radio to a "line in" input on the sound card. If your radio has one receiver, this will probably use the left channel of the sound card; with dual receivers, the second receiver may use the right channel. If your sound card does not have a line level input, you may need to use a microphone input, and in this case you may need an attenuator to reduce the line level output from the radio to the lower level needed for the microphone level input on the sound card.

To transmit, there must be some means to convey modulation from the computer to the radio. For FSK RTTY, this is an on-off keying signal, which is normally generated by a serial port connected to the radio's FSK keying input through a simple keying circuit. This serial port cannot be the same port that is used for radio control or for a Winkey or other serial device. If it is a USB-to-serial adapter, you will probably need to use MMTTY's EXTFSK plugin.

For AFSK RTTY and for all other sound card digital modes (e.g. PSK31), there must be a connection from the sound card's output ("line out", or speaker or headphone output) to the radio's audio input. If the only audio input on the radio is a microphone input, you may need attenuation to reduce the level to avoid overdriving the transmitter.

You also need some means to control TX/RX switching (PTT). If you are using software radio control, and if your radio supports PTT via radio command, you can use this method. Alternatively, you can use hardware PTT control from a serial or parallel port via a simple keying circuit. If you have a serial port set up for FSK keying, you can use a control line (usually RTS) on this same port for PTT control. Hardware PTT can be controlled either from the digital "engine" (MMTTY, MMVARI or Fldigi), or from N1MM Logger itself; software control (via radio command) can only be done directly from the Logger. The Configurer can be used to set up any of these different possible methods. If PTT is controlled from a digital engine rather than from the Logger, you will need to check the Digital box for that serial port in the Configurer.

1.1. Downloading and Installing MMTTY

MMTTY is not installed as part of the installation of N1MM Logger. It must be downloaded and installed separately. It is possible to use N1MM Logger in RTTY without using MMTTY (e.g. by only using an external TNC, or AFSK RTTY from MMVARI). If you intend never to use MMTTY, you can skip the rest of this section. However, most RTTY users will probably want to have the ability to use MMTTY, at least as an option. In particular, if you would like to make use of the additional RX windows for "diversity decode", you will most likely need to install MMTTY (unless you have several TUs/TNCs you can use for the purpose).

If you do not have a copy of MMTTY, then before continuing with the digital setup it is recommended that you download a copy of the MMTTY installer from the MM HamSoft website at http://mmhamsoft.amateur-radio.ca/ . You can find a copy of the full installer for the current version of MMTTY at that website. This file is a self-extracting executable, similar to the N1MM Logger installer. Download the file to a temporary folder and then execute it. It is recommended that you install MMTTY in its own program folder and not in the N1MM Logger program folder. By default, the installer will install MMTTY to C:\Program Files\MMTTY\ .

If you already have a copy of MMTTY installed on your computer, you can use that copy from N1MM Logger. However, if you also use MMTTY stand-alone, it is possible that you may want (or need) to have a different setup for stand-alone use than with N1MM Logger (e.g. if you use the radio control port from within MMTTY stand-alone; this is not possible when MMTTY is used with the Logger). If you need a different setup with the Logger than the one you use stand-alone, then you should create a separate folder for each copy (for example, you can create a sub-folder inside either the N1MM Logger program folder or the MMTTY program folder for the second copy of MMTTY). You need to copy only the MMTTY.exe and UserProfile.ini files from the main MMTTY folder into the additional folder. MMTTY will create a separate copy of MMTTY.ini when it is run.

If you plan to use two copies of MMTTY in SO2V or SO2R mode, one for each received audio stream, you will need to create two copies in separate folders with different configurations. In SO2V, one of these copies can be configured to use the left channel and the other copy to use the right channel of a single sound card. In SO2R, you can either use a stereo sound card as in SO2V, or you can use two separate sound cards, one for each radio.

If you want to use MMTTY for diversity decoding in additional RX windows, you will need to create another separate sub-folder for each additional RX window. For example, you can create sub-folders called DI1, DI2, DI1RX1, DI1RX2, DI2RX1 and DI2RX2 so that you can run up to six copies of MMTTY simultaneously; one for each main DI window, plus up to 4 additional RX windows (two additional windows for each DI window). Into each of these windows, you need only copy the MMTTY.exe and UserPara.ini files from the main MMTTY program folder created when you first installed it. Each copy will then be configured to use the appropriate sound card and channel. The "Additional RX" copies use the same sound card and channel as the parent copy in the main DI window, but they can be configured to use different decoding algorithms or profiles to give you "diversity decoding", i.e. two or three different decoding methods used on the same receive audio.

Note for users of Windows Vista and Windows 7: User Account Control (UAC) in these versions of Windows prevents user programs from writing configuration information into the Program Files path. Even if programs are run with Administrator privileges, UAC may interfere with the ability to use separate configuration files for separate copies of the same program. Therefore, it is suggested that the folders for the extra copies of MMTTY used in the two DI windows and the four RX windows should not be in the Program Files path. It is suggested that you create a new folder outside the Program Files path, such as C:\Ham Radio\MMTTY, and then place the individual sub-folders for the separate copies of MMTTY within that folder.

Once MMTTY has been downloaded and installed, you can proceed to use the Configurer to set up N1MM Logger to use it.

1.2. Downloading and Installing Fldigi

FLdigi is not installed as part of the installation of N1MM Logger. It must be downloaded and installed separately. It is possible to use N1MM Logger in RTTY and PSK contests without using Fldigi. Fldigi supports a wide range of other digital modes, but most of these are rarely used for contesting. If you intend never to use Fldigi, you can skip the rest of this section.

If you do not have a copy of Fldigi, then before continuing with the digital setup it is recommended that you download a copy of the Fldigi installer from the W1HKJ website at http://www.w1hkj.com/ . You can find a copy of the full installer for the current version of Fldigi at that website. This file is a self-extracting executable, similar to the N1MM Logger installer. Download the file to a temporary folder and then execute it. It is recommended that you install Fldigi in its own program folder and not in the N1MM Logger program folder. By default, the installer will install Fldigi to C:\Program Files\Fldigi-x.xx.xx\, where x.xx.xx is the Fldigi version number.

Note that Fldigi cannot be configured to use a single channel of a stereo sound card; Fldigi always uses its sound card in mono mode on receive. If you want to use Fldigi in a two-receiver configuration, either SO2V or SO2R, you will have to use two separate sound cards. You will also need to install two separate copies of Fldigi in separate folders, one for each DI window, in order to be able to configure each one for a separate sound card. It is suggested that you do a full install for each copy, but do not create Start menu or Desktop shortcuts for the second copy. As with MMTTY, users of Windows Vista and Windows 7 may find it necessary to install one or both of these copies outside the Program Files path.

You do not need to install separate copies of Fldigi for additional RX windows, because this feature is not implemented for Fldigi or MMVARI engines, only for MMTTY and hardware TUs/TNCs.

1.3. Setting Up the Configurer

There are three tabs in the Configurer that need to be set up when configuring N1MM Logger for digital modes. The first is the Hardware tab, where serial ports used for digital modes are set up.

• The Digital box in the main Configurer window indicates to the Logger that this port is used for digital mode control.
  • Use this to indicate a port that is used for an external TNC
  • Use this to indicate a port that is used for FSK keying with MMTTY
    • A port that is used for FSK must also be configured inside the MMTTY setup. This includes ports used with EXTFSK
    • It is possible to use a port in the range COM9-COM16 for FSK with MMTTY. In this case, there is no Digital box to be checked; the port must be configured entirely within MMTTY
  • Use the Digital box to indicate a port that is used for PTT in AFSK RTTY or other digital modes with MMTTY, MMVARI or Fldigi
    • Exception: If PTT is done from a radio control port or from a Winkey, do not check the Digital box for that port
    • It is possible to share a port for both serial port CW keying (e.g. on DTR) and for PTT and FSK using MMTTY for RTTY (e.g. on RTS and TxD of the same port). In this case, check both Digital and CW/Other for that port. When in CW mode, the settings in the DTR and RTS boxes will determine how the port is used; in RTTY, it will be the settings in MMTTY that determine how the port is used

In the Set window for each of these serial ports, the radio and the DI window associated with the port is configured.

• The Radio Nr box indicates which radio this digital interface is for in SO2R mode; in SO2V and SO1V, Radio Nr is always = 1
• The Dig Wnd Nr indicates whether this port is used for DI1 or DI2. This applies to SO2V and SO2R; in SO1V, Dig Wnd Nr is always = 1
  • You must choose a Dig Wnd Nr for each port that has the Digital box checked; otherwise the program will not assign the port to a DI window!

The next tab to be set up is the Digital Modes tab.

• MMTTY (if used)
  • TU Type: Soundcard
  • DI-1/2 MMTTY Mode: Select AFSK or FSK
  • DI-1/2 MMTTY Path: Select path to MMTTY.EXE
    • The path does not need to be in the N1MM Logger program directory
    • The paths for the two DI windows do not need to be the same

• MMVARI (if used)
  • TU Type: Soundcard
    • Other settings on this window do not matter for MMVARI

• Fldigi (if used)
  • TU Type: Soundcard
  • DI-1/2 Fldigi Path: Select path to fldigi.exe
    • The paths for the two DI windows do not need to be the same. In the example shown here, two different versions of fldigi have been used

• External TNC (if used)
  • TU Type: Other
    • Set other parameters appropriately for the TNC in use (Example settings: 9600, 8, N, 1, Xon-Xoff)

The third tab to be set up is the Mode Control tab, which determines what mode the radio will be set to use in RTTY and PSK.

The available choices in the list boxes under Mode sent to radio will depend on the particular radio type. For FSK RTTY, the correct choice will normally be RTTY. For AFSK RTTY, depending on the radio the appropriate choice might be AFSK or LSB/USB. For PSK and other sound card modes, the radio mode would be PSK (if available), AFSK-R (on some radios) or USB on most radios. For more information, see the Configurer page under the Config >Mode Control tab.

2. The Digital Interface - Window

The Digital Interface window is nearly the same regardless of which type of interface (MMTTY, MMVARI, FLDIGI or TNC) is being used. Its appearance (foreground and background font colors) can be customized using the Settings > Setup menu item.

The Digital Interface is opened from the Entry window's Window > Digital Interface menu item. If you are using two entry windows (SO2V/SO2R), each entry window has a separate DI window associated with it - DI1 with the VFO A/Radio 1 Entry window, and DI2 with the VFO B/Radio 2 Entry window. Each DI window is opened from its corresponding Entry window's menu bar.

The Digital Interface caption displays the offset frequency (radio's dial frequency +/- audio frequency). If you are using LSB/USB mode on the radio, this offset frequency is what should be used in the log and the bandmap. You can check the Use Auto TRX Offset in DI1/2 checkbox(es) in the Digital Setup window to cause the offset frequency to be passed to the Entry window. If you are using a dedicated RTTY mode on the radio (e.g. for FSK) and the radio's dial displays the actual mark frequency, uncheck this checkbox and ignore the offset frequency in the DI window title bar.

• TX - Indicator to show which window has transmit focus (useful when using two sessions like SO2R)
• Letters/Figs - Shows the text under the mouse in reverse case (letters/figures switched)
• MouseOver - Shows the text under the mouse; this is the text that would be selected by a mouse click
• 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, or, whenever a callsign is detected in the RX window it will be sent to the callsign grab window for easy movement to the logging window by clicking the Grab button. By clicking on the colored bar 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 bar will turn Yellow. To turn input to the window back on click in the bar 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 select and 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). 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 it will be placed in this textbox and when you press the Grab button it will transfer the callsign over to the main Entry 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. The Sort Order in the grab window can be selected by right-clicking; you can choose either Last In First Out or First In First Out as the sort order

• 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 adjust in relation to the width of interface
• Clr RX - Clear the receive window (also possible using the right click menu)
• Align (MMTTY and Fldigi only) - This is used to move the signal that you are copying into the pass band of your filters. Set the frequency in the setup area. For example, if your filters are centred on 2210 Hz, RTTY signals close to the 2125/2295 Hz pair will be copied well, but signals at higher or lower frequencies may not make it through the filters. If you click on such a signal to decode it, it may not decode very well. After clicking on the signal, if you click on the Align button your transceiver will be retuned to line the signal up on the configured frequency. This is essential in FSK where the transmit frequencies are fixed in the radio, and useful also in AFSK if you want to use narrow filters
  • Note that when you are using the MMVARI interface engine, the Align button appears on the MMVARI window instead of on the Digital Interface window
• TX - Start the RTTY transmission, the transceiver is keyed. Will be colored Red when transmitting
• RX - Stop the RTTY transmission - the transceiver changes back to receive. Will be colored Green when in receive
• Lock (Fldigi only) - Locks the transmit frequency at the current location. If you move the receive frequency, e.g. by clicking elsewhere in the waterfall, the transmit frequency does not change. Used for operating split
• Rev (Fldigi only) - In sideband-sensitive modes like RTTY, reverses the tones (e.g. opposite sideband)
• Grab - Transfer the selected callsign in the Callsign textbox to the callsign field on the main logger window. Once the callsign is filled, whatever you click on next will fill the next box to have info entered in. When the Digital Interface is in transmit, calls are not added to the Grab window
• CLR - Clear the Grab list

2.1. Callsign coloring

When a callsign is recognized in the receive input stream the callsign will be colored and brought to the Grab window. Valid callsigns that are separated by spaces are always recognized, and optionally the Search routine can be used to search for known call signs from the Master.dta file in garbage text strings. When the search in garbage text is enabled and two calls are found in the same string, only the last one gets highlighted. Also, if the call sign being copied contains a shorter call sign that is in the Master.dta file, using the search in garbage feature may result in the shorter call sign being recognized instead of the longer one. The highlighted calls in text strings are clickable.

If the "Use Generic Routines" option is chosen in the Digital Setup, anything that looks like a callsign will be highlighted with a color that indicates its multiplier status using the same colors as in the Bandmap and Entry window. If the "Use Master.dta File" option is chosen, only call signs in the Master.dta file will be colored according to the multiplier status; callsigns that are not in the Master.dta file will be given a different highlight color to indicate that they were not found in Master.dta. Regardless of which option is chosen, any callsign that passes the check routines will be placed in the Grab window.

2.2. Mouse Assignments

• Left mouse key clicking
  • Single clicking on a callsign grabs it and places it in the Callsign field on the Entry Window dialog
  • Single clicking on Exchange info etc. grabs it and places it in the Exchange field on the Entry Window dialog
    • NB. The callsign field must be filled first!
  • Double clicking on a callsign grabs it and overrides the current information in the Callsign field on the Entry Window dialog
  • Ctrl+Single clicking - will force what ever you are clicking to be sent to Entry window. (Must click first in Entry window where you want to place the new data)
  • Shift+Single clicking - will cause the moused over text to be Letter/Figs converted on the fly while sending to Entry Window (only in RTTY Mode)
• Right mouse key clicking on RX window
  • Will give a menu only when the menu item 'RT Click = Return NOT menu' is NOT selected!
    • Clear RX - Clear the receive window. This receive buffer can contain a maximum of 10,000 characters
    • Output to Text File - Output the received text to a text file named RTTY1.txt

• Ctrl+K - Toggle TX/RX, and displays the CW/Digital Keyboard window to send manual information using the keyboard
• Alt+G - Grab most recent callsign from callsign textbox. Upon grabbing that callsign gets deleted from the grab list
• Ctrl+Left/Right arrows - When 2 radios are configured and 2 digital windows are open (SO2V or SO2R), pressing Ctrl+Left arrow or Ctrl+Right arrow will swap from one active Digital Interface to the other. Digital Interface 1 will follow VFO A/Radio 1, Digital Interface 2 will follow VFO B/Radio 2

3. The Digital Interface - Menu Selections

The digital interface has a menu at the top which is also a little different per type of interface selected. As the differences are minimal, the menu items for all interfaces can be found below.

3.1. Selection: Soundcard as Interface

• Setup
  • Settings - Setting up the Digital Interface, see the paragraph 'Setting up the Digital Interface' below
  • Bring to Foreground when made Active - Bring the Digital Interface and Engine to the foreground when its Entry window has focus

  • Open Add. RX Window (4 Avail.) - This allows you to open an auxiliary RX window for diversity decoding of the same RTTY signal, e.g. by using a TNC in the main DI window and MMTTY in the auxiliary window, or by using a different copy of MMTTY with a different decoding algorithm to decode the same audio input
    • There are up to 4 such windows available. They can be called up from either DI1 or DI2
• Interface
  • MMTTY - Select MMTTY or Other (TNC) as the interface
    • Requires MMTTY to be installed and the DI-1/2 path(s) to MMTTY to be set up in the Configurer
  • MMVARI - Select MMVARI as the interface
    • No other installation required - the MMVARI engine is installed during the N1MM Logger install

  • Help - Shows help file

4. 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.

4.1. Tab: General/MMTTY Setup

This interface has general setup information for ANY type of interface (Soundcard of external TNC) and some specific settings for MMTTY, MMVARI and Fldigi.

• 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 1.
  • When setup correctly 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)
• Remove Excess Linefeeds from RX Window - Ability to strip excess linefeeds from RX Window
• Send Space on Using Grab - Setting for sending space after grabbing call from grab window
• (MMTTY) Send HamDefault on Run to S&P change - (MMTTY only) Ability to have Ham Default(MMTTY) sent when going from Run to S&P to reset Mark Frequency. 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
• Send Space on Using Grab - when doing a grab from the grab window it will also send a space press command to Entry window to advance the cursor
• If QSY Wipes call is checked Clear Grab Window on QSY - If QSY Wipes and Spot call is checked then Clear the Grab window on wipe of callsign.
• QSY will clear Grab Window - Changing frequency will clear the Grab window
• Clear Grab Window On CQ - sending CQ will clear the Grab window

• Callsign Validity Routines
  • Use Generic Routines - the generic routines will highlight anything that passes the check routines (and probably will look like a callsign)
  • Use master.dta File - when selected only the callsigns in the master.dta file will be highlighted
    • Highlight Color for non-Master.dta calls will be shown in the shown color.
  • Use Search routine to find Master.dta in Garbage Text - ability to turn off checking for callsigns in garbage text in digital modes
  • Highlight Foreground Text - call sign text will be in the highlight color on the normal background
  • Highlight Background of Text - background color surrounding call sign will be changed to the highlight color

• Digital Interface Window Colors

  • Control Button's - Shows waterfall/spectrum plus control buttons
  • Give MMTTY help Starting - Turn MMTTY kick-starts off and on

• Preferred RTTY Interface - Select the preferred RTTY interface. Choices are: MMTTY, MMVARI, TNC or Fldigi

• Preferred PSK Interface - Select the preferred interface for PSK (and other sound card modes). Choices are MMVARI and Fldigi

• On Top Settings
  • MMTTY always on Top - MMTTY is always in front of all other N1MM logger windows. A restart of N1MM logger is needed to activate this function. Minimizing the N1MM logger program will not minimize the MMTTY engine
  • MMVARI always on Top - MMVARI is always in front of all other N1MM logger windows. A restart of N1MM logger is needed to activate this function. Minimizing the N1MM logger program will not minimize the MMVARI engine
  • Fldigi always on Top - Fldigi is always in front of all other N1MM logger windows. A restart of N1MM logger is needed to activate this function. Minimizing the N1MM logger program will not minimize the Fldigi engine

• Save Configuration - Save the made configuration changes. If the changes made should not be saved select the X in the upper right corner to close the window

4.2. Tab: MMVARI Setup

• MMVARI Engine
  • Waterfall/Spectrum/Misc Color palette - The colors that make up the color palette can be changed to represent whatever colors you would like. The colors go from the weakest signal on the left to the strongest signal on the right. There is a color palette setting for the Waterfall, Spectrum and for Miscellaneous colors. The Default button changes the colors back to the default colors
  • Squelch Level - This level represents the noise level where you would like the interface to start copying signals. 0 indicates an open squelch and everything will be decoded
  • High Pass Filter - Select 'Use High Pass Filter' to use the internal high pass filter for RX. Although this is unnecessary with most soundcards, it sometimes is effective for eliminating hum in the input audio
  • Spectrum Lower Frq - the lower frequency to display when the Spectrum view or Waterfall is active
  • Spectrum Upper Frq - the upper frequency to display when the Spectrum view or Waterfall is active
  • CW ID
    • Enable - If this check box is checked (Enabled) the interface will send the string entered in the field (Enter CWID String) in CW after every transmission. A * will be substituted by SK, + by AR and = by BT
  • AFC Search Range - This is how far in Hz the interface will track a drifting signal i.e the frequency sweeping width (+/-Hz) for the AFC
    • Sense Level - specifies the S/N level (dB) for the wide AFC. When the search range is less than or equal to 50 Hz, the wide AFC does not function. The sense level is applied to all the RX channels
  • Use TNC Software for control - When selected N1MM logger will release the serial port for the TNC so the soundboard in the TNC can have control. When using an external TNC the internal soundboard can be used
  • Digital Output Level - specifies the digital output level in the range of 0 to 32767. The default value is 16384

• DI1/DI2 MMVARI Soundcard
  • MMVARI Soundcard #
    • Input Souncard# - Select the input soundcard to be used when there is more than one soundcard in your computer (maximum 4)
    • Input Channel - Select the input channel. Mono, Left channel or Right channel
    • Output Souncard# - Select the output soundcard to be used when there is more than one soundcard in your computer (maximum 4)
  • FIFO
    • RX - specifies the depth of the RX FIFO. Valid values are 4 to 32
    • TX - specifies the depth of the TX FIFO. Valid values are 4 to 32
  • Clock - Soundcard Clock adjustment
    • RX - specifies the tuning parameters of the RX clock adjustment function
    • TX Offset - the offset of the TX frequency compared to the RX frequency
    • Graphical Adjustment - Graphical RX clock adjustment
      • The computer clock itself is not very accurate (+- 100 ppm); that is why to use WWV or another precision source to calibrate the soundcard
      • 1. Tune to WWV or another Time Mark; adjust so tick is on 1000 Hz in Spectrum of MMVARI
      • 2. Wait for line to appear in display and adjust Clock Freq so line appears straight and not at an angle
      • 3. Click button to save new frequency when line is straight up and down

• MFSK (MFSK only)
  • Handling Center Frequency - When selected the center frequency is used for the carrier frequency. When not selected the base tone frequency is used for the carrier frequency
  • Use Metric Level Squelch - Select to use the metric level for the squelch. When not selected the S/N level is used for the squelch
• # of MMVARI channels - Number of MMVARI channels to use. Choices are 1, 2, 3 or 4
  • Note that if this is set to 1, you have the option to select the Multi-Channel Rx menu item in the MMVARI menu bar, but when it is set to 2, 3 or 4 this option is not available
• Save Configuration - Save the made configuration changes. If the changes made should not be saved select the cross in the upper right corner to close the window

4.3. Tab: Macro Setup

• Digital Macro Set Select Interface Type and Window Number to begin - Update the macros definitions and button texts
  • Select an interface (TNC or soundcard DI) from the drop down menu. Choices are:
    • MMVARI - macros for the MMVARI interface
    • MMTTY,Fldigi - macros for the MMTTY and Fldigi interfaces
    • Other - macros for the TNC
    • Dxp38 - macros for a DXP38
  • Click on the macro button which has to be updated
