Tips, Updates, & Changes To CT Since The Manual Printing

Current with CT version: 10.03

Program General & Startup

Do not run CT DOS in a Windows DOS window, use the Windows version of CT instead.

Always download the latest version of the CTY and MASTER database files before a major contest. They are updated regularly and available on the CT web page. It’s a good idea to keep the last few versions of these files in your archives.

The CT.HLP file has been recently updated by Ed, K1EP. Download and it place it in your CT directory. This file is viewable during the contest by typing ALT-H. Use ALT-H or ESC to close the help window.

Command line switches have been added and some existing command line switches have changed. Here a complete list of CT command line switches for the current versions of CT grouped by function. Although shown in upper case, they are not case sensitive.

COM, LPT, Ethernet

  -AC Enables LPT antenna control for the TopTen Devices controller.

  -DIGI Controls the 8 port Digiboard with a single IRQ.

  -ENET CT Win startup switch to enable the Ethernet network. See the Utilities section for information on NETTSR.

  -LOOP Enables the single port loop serial port network. With special serial cables, one serial port can be used to communicate with two computers. 

  -NC Disables all COM port activity.

  -NOLPT Disables all LPT activity.

  -SHARED Controls the 4 port MU440 card with a single IRQ.

Video

  -L Forces monochrome colors for older laptops. Without this switch, screen colors can be changed with the COLORS command.

  -RESET Resets all screen colors and positions to default values when CT starts. Useful when a window is off the current screen and can not be viewed.

  -VGA Enables the 50-line VGA mode. Useful on DOS computers with VGA capability and some Windows computers running CTWin.

Operating & Miscellaneous

  -BOH In TWORADIO mode, while F2, F3, F6 or F7 is sending, CT switches the receiver to the none-CQ radio. This allows search and pouncing during these transmissions.

  -CFG Causes CT to load the configuration stored in CT.CFG instead of the configuration in the *.bin file.

  -CQTC Resets the WAE log QTC-sent pointer to zero after using trunc_bin on the log. Start CT once with this flag after running trunc_bin.

  -DEBUG Creates files in the CT program directory which are used to debug radio communications problems. Start CT with this switch to document the radio commands issued. CT will record the radio response for later debug by K1EA.

  -FO In CQ REPEAT mode, prevents CT from ending a transmission when a key is pressed.

  -HP Causes CT to write files using HP PCL4 codes for compressed printing.

  -KA When the call in the callsign field is a dupe, pressing F4 will not send your call. It sends the dupe message instead.

  -KY1H Widens the Check Call and Check Country windows and adds distance to the Check Country window.

  -LTA Announces band changes in Morse code for blind operators.

  -LZ Send leading zeros in serial number exchanges. 

  -MO Accepts only QSO's with new multipliers from networked computers. Used when memory is low.

  -NF Eliminates passing frequency changes around a multi-computer network.

  -NLT Eliminates saving the multi-op GAB messages in the *.TLK file.

  -NOM Disables the multiplier window for low memory conditions.

  -NOW Bypass all input and startup windows for fast startup with an established log file.

  -ON Sends DL7ON style QTC reports in the WAE contests for use with a tape recorder.

  -RESET Used to reset all screen colors and window positions to default values when CT starts.

  -TT Removed starting with version 10.3. Clears all fields when a backspace in the callsign area results in an empty field.

Removed & No Longer Needed

  -D  CT always looks for a MASTER.DTA file.

  -K1XM  Removed.

  -M  Removed.

  -XT  Removed.

  -2  Removed.

CT DOS assumes your computer is set to UTC. If you wish to leave it on local time, set the TZ environment variable. CT DOS doesn't compensate for daylight savings, thus avoiding the sudden change in time during CQWW SSB. The first three letters of the TZ variable doesn't mean anything, but the time offset does. For example:

  SET TZ=EST5 5 hours behind UTC

  SET TZ=PDT7 7 hours behind UTC

  SET TZ=CEU-2  2 hours ahead of UTC

  SET TZ NST3:30 3 hours 30 minutes behind UTC

It is also valid to omit the alpha characters of the TZ variable as in this example:

SET TZ=4 4 hours behind UTC

There are many startup items that can be specified in the CT.CFG file. Remember to save this file as text if editing this file with a Windows editor. Here is a complete list of items that can be specified in the CT.CFG file.

When CT starts the directory search order for files is: 

   1. The directory containing the .bin file.

   2. The directory pointed to by the CTPATH environment variable.

   3. The directory containing the executable.

For example, if your current working directory is: C:\HOME and you type the line: 

D:\CT\CT.EXE D:\CT\LOGS\CQWW\CQCW99.BIN CT will use the CTY.DAT file in D:\CT\LOGS\CQWW.

Utilities

Many CT utilities are available on the CT Website. Some CT utilities are version (version 8, 9, or 10) or operating system (DOS or Windows XP) specific. Make sure that you are using the proper version of the utility that applies to your *.bin file version and operating system.

DOS utilities seem to run fine in a Win98 DOS window but they will not run in a WinXp cmd window. You need to download the Windows version of that utility for use with WinXp.

If the utility does not exist for version 10, use the utility 10to9.exe to convert your .bin file to version 9 so you can used the older utility program. If required the log can be converted back to version 10 format with 9to10.exe

You can run the CT utilities from a Command window or from the Windows interface. To open a command window in Windows, click on Start | Run and enter cmd.exe on the “Open:” line. If a command window doesn’t appear, enter command on the Run line. Once the command window opens, you must change directory ( CD ) to the location of the files and utilities before attempting to run the utility program. It may be easier to use the Window interface in advance and copy the necessary files to a simple directory in the root like c:\ct so it’s easy to navigate to the directory when using the Command window input. The added advantage is that you will be working on a copy of your files. You can also run the CT Win utilities by clicking Start | Run and entering the CT utility command with fully qualified pathnames on the “Open:” line.

Use the CT utility written by Jim, AD1C called C2A to convert CT logs into ADIF format for simple import into logging programs such as DX4Win. This utility is available on the CT web page and it works with all CT *.bin files starting with version 5.

NETTSR written by K1TTT allows CT DOS to link to other CT DOS or CT Win computers. Documentation for NETTSR can be found at:

www.k1ttt.net/software/nettsr.html The network address line needs to be changed from the default if you are linking to a CTWin computer. The CT Win computers need to be started with the –enet switch to enable Ethernet linking.

CT Keyboard overlays are available from WA4PGM at: http://www.wa4pgm.us/my_station.htm

Software voice keyer that works with CT is available at: http://sm3w.magicbug.co.uk/homebrew/voice_keyer.php

A label printing program that is popular with CT users is available at: http://www.df3cb.com/bv/index.html

CTWIN

CT Win is supported for Windows 98 or newer. It is not supported for older Windows versions (i.e. Windows 95).

CT Win does not require the installation of TSR's or *.BAT files. When selecting COM ports for I/O check the Windows hardware configuration to determine the COM port number. Some I/O card Window drivers do not assign the port numbers in sequence.

Ethernet linking is directly supported in CT Win and very easy to use. Use the -ENET startup switch to enable the Ethernet network. Be sure to assign different station numbers to each computer during program startup. The multi.cfg file in the CTWin directory is used to customize the station number text when sending Gab messages.

CT Win can be used in an Ethernet network with other computers running CT DOS and K1TTT’s nettsr. The K1TTT nettsr information and files are available on the CT web page. When networking CT DOS and CT Win computers with Ethernet, some changes must be made to the CT DOS nettsr startup command or Ethernet linking will not work. Using the same version of CT is advisable on all computers.  

To add command line startup options with CT Win click right on the CT Win icon and select Properties. Place command line options after and outside the double quotes on the Target line. 

Example: "C:\Program Files\K1EA Software\CtWin\ctwin.exe" -vga -enet

Use ALT-ENTER to toggle between the window and full screen modes. Achieving the CT DOS 50-line full screen look may require some experimenting and the outcome will depend on the video card, driver, and operating system. Some computers may require the font mode to be changed from the keyboard to allow full screen operation while others may not toggle to full screen mode the first or second time (Toshiba 660CDT). It is known that computers with some Savage video chipsets produce very coarse fonts in the full screen mode that are unusable with CTWin. CTWin writes to the console window and the video quality can be tested outside of CTWin by opening a console window with Start | Run | then type: cmd. To check the window and font quality force the cmd window to full screen with ALT-Enter. The quality of the text that appears in this window will be based on the computer video chipset and video drivers and it will be identical to CTWin full screen mode.

WinXp users should find that using the -vga command line option and setting the icon Properties, Layout tab, Screen Buffer Size and Window Size both to Width = 80, Height = 50 works well. With Win98, some experimenting may be necessary with the -VGA command line switch. It may be useful to add the –RESET command line switch until the proper layout settings have been found.

The ability to telnet to internet DX clusters is supported in CT Win. The Telnet section below explains how to use CT Win and telnet.

CT Win supports LPT port CW keying, PTT, band information, radio1/radio2, and CW paddle input. After installing CT Win for the first time, you may have to reboot the PC to activate the CW sending function. Users report that USB to LPT converters do not work with CT Win.

CT Win supports COM port radio control, TNC, and COM port networks. Currently, COM port CW keying is not supported by CT Win. The MicroHam USB interface has been reported to successfully control the radio from a USB port but it does not send CW. There may be other USB to COM port adapters that will also control a radio.

Mouse control works with CT Win. Under WIN XP, you should turn off Quick Edit Mode and Insert Mode in the Properties box of the CT Window. To do this, click right on the window title bar and select Properties, then the Options tab. Uncheck the Quick Edit Mode and Insert Mode boxes. Click on OK and select "modify the short cut that started this window". With Win98 and WinME, you will find it easier to move windows by grabbing the center of the window instead of the edge of the window. To close any CT Window, click right in the window. If a window moves off screen, use the -RESET command line option to move all windows to their default positions.

When updating to a new version of CT Win, select the REPAIR option during the installation. Some users un-install the old version of CT Win with the Control Panel and re-install CT Win. Be sure to check for the latest CTY and master callsign database files after updating

CT *.bin files are not CT Win or CT DOS specific. A CT DOS *.bin file can be used with CT Win.

The DVP is not supported in CT Win.

See the Utilities Section for CT Win utilities information.

The later versions of CT Win are not available in the archive section of the CT web page. Until they are, consider saving previous versions of CT Win in case something undetected is discovered during a contest.

There are some CT text commands that do not work correctly in CT Win. The commands known to have problems are: PRINTMULT, NOPRINT, and DEFINEKEY.

CW & PTT

The half space character has been changed to a "^" (shift 6). This character can be used one or more times in the programmable CW messages.

Use the '+' and '-' characters one or more times in CW messages to speed up or slow down the morse characters three wpm (five wpm prior to version 10.03). At the end of the message or after ESC has been pressed, the CW speed reverts to the programmed keyboard rate so there is no need to balance the '+' and '-' symbols.

CW paddle input via the LPT port has been added. It is enabled via the program startup menu by selecting SuperCMOS, CurtisA, CurtisB or BUG. The keyer type can be changed by entering NOKEYER, SUPERCMOS, CURTISA, CURTISB, or BUG on the callsign line. The CW paddle inputs on the LPT connector are pin 13 - dot and pin 12 - dash. If the computer LPT port does not have pull-ups on pins 12 and 13, you will need to add a 10K resistor from each of these pins to Pin 14 of the connector.

The LPT pinout now includes a PTT output that works with paddle or computer sending. Several text commands have been added to control the assertion of PTT. They are explained below.

Operating

Partner Mode has been added and explained below in the command section.

Whenever operating in the Multi-Two class, each computer must be identified for CT to function correctly. The text commands RUNSTN,  RUN1, STN1, TX1 are all equivalent and set that computer to Transmitter 1. Likewise, MULTSTN, RUN2, STN2, TX2 all set the computer to Transmitter 2. The key sequence ALT-Y allows the operator to toggle between RUN1 and RUN2.

Calls may be entered in the bandmap without a computer controlled radio. Type the callsign, then press CTRL- ENTER. CT prompts you for a frequency when there is no radio selected during startup.

Most windows in CT toggle open and close by repeating the keystroke that opened the window. Those that do not, they can be closed by placing the mouse pointer in the window and click the right mouse button.

CT supports Point and Shoot for the Band Map and Announce Windows. The command used to enter the appropriate window is different. To place the cursor in the Band Map, use ALT-RightArrow and to place the cursor in the Announce Window, use CTRL-RightArrow. Select the spot with UpArrow or DownArrow keys and press ENTER to select the spot and change the radio frequency. You may delete a spot in either window by placing the cursor in the window, selecting the QSO with the arrow keys, and then pressing the DELETE key. The Point and Shoot operation may be canceled prior to pressing ENTER with the ESC key. If you pressed ALT-F5 to memorize your run frequency prior to using Point and Shoot, you can press ALT-F4 to return to your run frequency. If you return to your run frequency without working the station, ALT-F4 can be used to return to this spot without using Point and Shoot keystrokes.

Switching between Radio 1 and Radio 2 was possible with either the  '.' (PERIOD) key or ALT-'.'  (ALT-PERIOD). Later versions ( starting with V10.02.003 ) only switch with the ALT-. command.

The Ctrl-Enter and Ctrl-J keyboard commands now wipe the callsign field after entering call and frequency in the Bandmap and Announce windows.

In the CW contests, ALT-1 (not ALT-F1) through ALT-5 (not ALT-F5) will send certain elements of the exchange - i.e. the serial number, precedence, call, check and section for SS. Try them before the contest begins to see what they send for that contest!

Gab (ALT-G) broadcasts to all computers if you press <Enter>. Use Ctrl-Enter to direct a gab message to a particular station.

In the WAE contests for European operators, CT allows editing of QTC forms with the Cursor Left, Cursor Right, Home and End keys. The QTC form sent by DX stations now includes frequency information.

There are two methods to point antennas controlled by Yaesu rotors. Enter the callsign prefix or beam heading into the callsign field and press Ctrl F10 to rotate the antenna. Rotor 1 is the default, but rotor 2 may be selected using ALT-SLASH, ( ALT and the '/' key pressed together). ALT-SLASH toggles between Rotor 1 and Rotor 2. Rotor error can be corrected with the text command OFFSET. 

On CW when CORRECT is enabled, CT will no longer send a corrected callsign twice if F4 is pressed prior to entering “+” to log the contact and send the F3 message.

When using Ctrl-Enter to manually add calls to the announce window, the entry is now marked with a # to indicate the entry was local and not from the cluster network. This is feature is used by multiops that use an additional station to spot new stations.

Ctrl Down Arrow now controls the DVP input gain again. It was use in earlier versions for partner mode.

When INS is pressed, the CALLSIGN and MULT windows are now updated to let the operator see what bands the station are needed on while the report is sent.

Remapped keys are inhibited when text is typed in the Packet (Telnet), Gab, and Notes windows.

Telnet

Without a doubt, the easiest way to link CT to internet DX clusters is to use CT Win. If you are using a dialup internet connection, establish the connection prior to starting CT Win. If the connection fails, there is no indication or error messages. Setting Windows to automatically dial the internet connection will eliminate the need to redial manually but you will have to manually reconnect to the cluster. In the CT Win startup, select TELNET in the packet options. After the program setup is complete, type ALT-T and press ENTER for the telnet address widow to appear. Enter a valid cluster address (example: dxc.k1ea.com or 205.247.190.48) and login. You may also add a port number to the telnet address. An example is: dxc.k1ea.com 7300 which will connect to port 7300 on dxc.k1ea.com. The CT Win default port is 23 (telnet), which is accepted by many, but not all IP connected clusters. To switch between telnet connections, exit the first connection by typing QUIT and then press ENTER for the telnet address window to reappear.

If your computer does not have Windows 98 or newer installed, you have to use CT DOS. There are several telnet options all requiring a second computer.

- Purchase DX Telnet and run it on another computer that is connected to the internet. Connect the DX Telnet computer and the CT DOS computer together with a serial port cable. DX Telnet has a special mode that outputs cluster spots on a serial port using CT DOS serial link. The instructions that come with DX Telnet explain how to configure the program to output cluster spots on the COM port. During setup of the CT DOS computer, select REMOTE in TNC window. The internet computer running DX Telnet needs to have a COM port available and the CT DOS computer needs a COM port with an unused IRQ for the COMTSR.

- Install CT Win on a second computer that is connected to the internet. Establish a serial port link or an Ethernet link between the CT DOS and CT Win computers. The serial port link requirements and setup are identical to above. Establishing an Ethernet link with a CT DOS computer requires an Ethernet card in the DOS computer with DOS drivers. The K1TTT port driver must be installed and configured to work with CT Win. The URL for the K1TTT documentation is in the Utilities section. Ct Win must be started with the –enet switch. This is explained in the CT Win section.

Many new text commands have been added to CT. A complete listing of all text commands with a summary of each appears below grouped by similar function.

Digital Voice Processor (DVP)

The DVP is not supported in CT Win.

BACKCOPY Starts the 30 second DVP continuous recording loop. See NOBACKCOPY.

DVP Opens the Digital Voice Processor (DVP) window. The DVP is not supported in CT Win.

MON Enables the DVP to monitor its own audio when transmitting instead of the receiver output. Use NOMON to disable.

NOBACKCOPY Disables the continuous DVP recording loop. See BACKCOPY.

NOMON Disables the DVP monitor. Use MON to enable.

NOPTT Disables the DVP PTT output. Enabled with PTT.

OFFAIR Prevents the DVP output from reaching the transmitter and disables PTT. Enabled with ONAIR.

ONAIR Enables the DVP output and PTT output. Disabled with OFFAIR.

OPOFF Creates an entry in the operators log statistics and reverts to the default DVP message.

OPON Used to identify the operator and switch the pre-recorded DVP phrases. The callsign of the current operator is added to the border of the summary window. When the log files are written, a text file ending in .OPR is generated listing the statistics of each operator.

PAUSE Sets the DVP pause in milliseconds between the callsign and the serial number.

PTT Enables the DVP PTT to the radio. Disabled with NOPTT.

File Output

The ADIF format file is generated with the C2A program that is available on the CT webpage.

AK1AFORMAT Writes an ASCII log file with the extension *.ASC. This file is not generated with the WRITELOG command.

BREAKDOWN Writes the *.BRK output file which is also generated with the WRITELOG command.

DUPESHEET Writes the *.DUP output file which is also generated with the WRITELOG command. Identical to the WRITEDUPE command.

WRITEARRL This command may no longer write any output file.

WRITECAB Writes the Cabrillo output file. The filename is the callsign used for the contest with a .LOG extension. Use WRITELOG to write all output files.

WRITECLIST Writes the *.CTY and *.CNT output files which is also generated with the WRITELOG command.

WRITEDUPE Writes the *.DUP output file which is also generated with the WRITELOG command.

WRITELOG Writes most but not all contest output files. The ADIF and *.ASC files are the exceptions.

WRITEMULT Writes the *.MUL output file which is also generated with the WRITELOG command.

WRITEPWR Writes the *.PWR output file. This file isn’t generated for some contests.

WRITESUM Writes the *.SUM output file which is also generated with the WRITELOG command.

Operating - CW

CORRECT Enables resending a corrected callsign before responding to the F3 or “+” input. Use NOCORRECT to disable.

CURTISA Selects CurtisA CW paddle type. This allows the sending of code at the same speed as CT. The CW Port and a keyer type must be selected during program startup. The paddles are connected to the LPT port and pin-out information is available on the CT webpage.

CURTISB Selects CurtisB CW paddle type. This allows the sending of code at the same speed as CT. The CW Port and a keyer type must be selected during program startup. The paddles are connected to the LPT port and pin-out information is available on the CT webpage.

CWABBREV Enables sending the CW number abbreviations (cut-numbers). Use NOCWABBREV to disable.

LZOFF Turns off the sending of leading zeros in serial number contests. Use LZON to enable leading zeros.

LZON Turns on the sending of leading zeros in serial number contests. Use LZOFF to disable leading zeros.

NOCORRECT Disable CW corrections. See CORRECT.

NOCWABBREV Disable CW abbreviations. See CWABBREV.

NOKEYER Disables the LPT CW paddle input. Enable with CURTISA, CURTISB, or SUPERCMOS.

NORPT Disables the CW RPT function. Use RPT to enable.

PTTDELAY Specifies the time PTT is asserted before the first Morse element in milliseconds. The minimum delay is 0 ms and the maximum is 255 ms. Most amplifiers should work fine with a value of 20.

PTTHANG Controls the time in dot times the PTT stays asserted after CT stops sending. A value of  5 seems to be equivalent to normal VOX delays.

PTTTAIL Same as PTTHANG.

REVPADDLE Reverses the dot and dash paddle inputs.

RPT Turns on the repeating CQ function. Use RPT to change the time and NORPT to turn it off.

SUPERCMOS Selects SuperCMOS CW paddle type. This allows the sending of code at the same speed as CT. The CW Port and a keyer type must be selected during program startup. The paddles are connected to the LPT port and pin-out information is available on the CT webpage.

ALTERNATE Used to toggle CQ's between alternate radios until you type a callsign. The next CQ starts the cycle again.

ONERADIO Used with two radio operation to enable manual mode.

TWORADIO Used with two radio operation to enable automatic mode.

Operating - Other

ALLRATE Displays the rate for all stations in the Rate window (ALT-R). See BANDRATE

AUTOSAVE Enables the periodic saving of the log to A:\ drive. Disabled with NOAUTOSAVE.

BANDMAPAGE Sets the number of minutes to keep a call in the bandmap or announce window before purging. The default is 60 minutes.

BANDRATE Displays the rate only for this station in the Rate window (ALT-R). See ALLRATE.

BEEP Enables the audible beep indicators for dupes, new multipliers, and other events. Reset with NOBEEP.

COLORS Allows the window, text, and screen colors to be changed. Use the COLORSAVE command to save the colors for new logs.

COLORSAVE Saves the selected colors and window positions in a COLORS.INI file that will be used for the current and new logs. The colors in old log files will not be changed. The COLORS.INI file is ignored if the –RESET command line switch is used.

CONT Set the Continent (NA, SA, EU, AS, or OC).

DEBUG This command was removed starting with version 10.03. Identical to the –debug command line start switch.

DEFINEKEY Allows the re-mapping of keyboard keys within CT. At the first prompt, enter the new key that you want to use for the CT key entered at the second prompt. To clear all re-mapping, enter CTRL-C at both prompts. When you use DEFINEKEY, a file named KEYDEF.INI is created in the CT directory which stores the key remapping and is automatically used when CT is restarted. The KEYDEF.INI file from CT DOS can be copied into the CTWin program directory. There is a known bug in CTWin that prevents the keyboard mapping of ALT-key sequences.

GABTIMEOUT Sets the Gab window timeout period in seconds. Entering -1 or FOREVER will eliminate the timeout and the Gab window will not close automatically. Entering 0 or 15 will set the timeout to the default value. Same as SETGAB.

GRID Sets the center of the grid square map in grid square contests when you type ALT-M. The home station grid square is set with MYGRID.

HELP Opens the help window. Use PAGE UP/DOWN to scroll and the ESC key or ALT-H to close the window. The displayed text is in the CT.HLP file in the CT directory. Updated CT.HLP files are available on the CT website. The key sequence ALT-H will also open the help window.

MEMLEFT Displays the number of QSO’s that can be logged with the available memory. During low memory conditions start CT with the –NOM and –MO command line switches and close all windows.

MYGRID Sets the station grid square in grid square contests.

MYSEC Used to set your section after the program has started. Same as SETSECTION.

NOAUTOSAVE Turns off the AUTOSAVE feature.

NOBEEP Disables the audible beep indicators. See BEEP.

NODEBUG This command was removed starting with version 10.03. Use the –debug command line start switch.

NONOVICE Used to designate the Non-Novice stations during Field Day. Band changes are allowed on all bands except 80N, 40N, 15N, and 10N. Use NOVICE for the Field Day novice station.

NORADIO Disables radio control. Use RADIO to re-enable radio control.

NOSOUND Disables the PC speaker CW sidetone.

NOVICE Used to designate the Novice station during Field Day. A red and white indicator is set next to the radio indicator and band changes on 80N, 40N, 15N, and 10N are allowed.

NOWORKDUPE Sets INS to answer dupe stations with the QSO B4 message. See WORKDUPE.

OFF Starts an off period. Use ON before beginning operation again.

OFFSET Sets the rotor offset in degrees.

OFFTHRESH Set the off-time threshold. The default is 10 minutes.

ON Begins an on period. Use OFF to signify the beginning of an off period.

OPON This is a DVP command but OPON can also be used to generator post-contest statistics of operators in a multi-operator environment. OPON places the callsign of the current operator it in the border of the summary window. When the log files are written, a text file ending in .OPR is generated listing the stats of each operator. The OPOFF command can be used to logoff an operator during breaks.

PARTNER Used to establish the station number of the Partner Mode computers. Issue this command on both the primary and partner computers. After the Partner Mode station number is entered, ALT-F11 or CTRL-F8 toggles the partner mode on and off. Partner Mode allows a second operator, with another computer listening in tandem, to send copied callsigns to the main operator. As the additional operator enters callsigns, they immediately appear in the grey field of the partner computer.
