CW Communicator 
Server Configuration

Download the program using this link:  CW Comm  

The USMT CW Communicator "Ionosphere" server address is:

For USMT DOT code, please use channel 1863 when connecting to the USMT ionosphere.

This page will show you how to configure your program for use with our server.

Main Screen

The screen shown below is the main window you will see when you run the program.

The buttons have been defined by us so you know which one to use.

First, you need to configure a key.  See the information below.

Connecting a Mouse to a free serial port

The advantage to the MRX software is that there isn't anything fancy about connecting your key.  Just take a simple serial cable, cut one end off and strip the wires.  Make sure they are well separated.  Then, connect it to your PC.  Run the program and configure it to use the serial port for the mouse.  Make sure you have the correct serial port enabled (1 or 2).  Now, using the end with all the strips of wire, take two at a time and connect them together with MRX Morse Code or CW Comm running.  If you have the right combination, you should hear a tone.  Keep trying until you have the tone.  Once you have the correct to wires, cut the remaining ones flush with the cable so those two free hang loose.  These two you connect to a straight key.  I have yet to find standardized colors of wire in serial cables.  Out of 5 cables I've looked at to connect to my computer, all of them had different wires out to each of the 9 pins on that serial cable.  Process of elimination is your best bet.  Of course, the other way to do this test is with the continuity test.  For other connections other than a straight key, please use the help menu.


Connecting to the USMT "Ionosphere"

To connec to the Ionosphere, you need to change the connections setting.  Click the "Connection" button.  The screen shown below will pop up on your screen:

First, change your callsign.  If you are licensed amateur radio operator, please use your call sign.  If not, please use your first, middle, and last initials (i.e., "TRW") or please use your first initial plus last name (i.e., "twagner").

Now, use your mouse and click inside the address field at the top of the screen.  Change the to ""

Do NOT change the port address.  In the lower section of the menu, there is a "Channel" setting.  The "default" channel is 1000.  This number represents a radio frequency.  For example, if you want to simulate connecting to 28.030Mhz on the 10 meter amateur radio band, the channel would be 28030.  Likewise, if you wish to connect to the frequency 7.030Mhz on the 40 meter band, the channel would be 7030.

Most likely, it will be sufficient enough to stay on channel 1000 unless you want to "practice" in private.

To connect to the server, simply click on the "Connect" button with your mouse.


CW Communicator General Setup

Click on the Configuration button to get into the configuration portion of the program.  You will see the following screen:

About the only think you may want to change on this screen is the "Incoming Morse Tone" setting.  Change this for tone heard.  Additionally, you may want to deselect the "Flashing Light" setting as shown above for both transmit and receive.

The CW Communicator program will "translate" messages it senses from morse code to text on your screen by default.  To change the speed of the incoming messages you hear, click on the Translation tab (screen shown below):

To change the speed, use the slider bar at the bottom of the screen.  

Additionally, CW Communicator translates all incoming messages to visual text.  If you are an experienced operator, or you wish to practice USMT DOT code, you will want to disable this feature.  In the "Translation" tab of this menu, deselect the option "Display TEXT for Morse".  This is the first possible selection you can make on this menu.  This is especially important if you plan to use the DOT code.  Otherwise, all you'll see are a bunch of e's, i's and s's.


Configuring CW Communicator for a 
Straigh Key Using a Serial Cable

To set the options for using a serial cable and a straight key, click on the "Morse Key" table of the configuration menu.  You will see the screen below:

Make sure the "Manual" selection is chosen for Morse Key and for Morse Input, make sure you have selected "Com Port".  Then, choose which Com Port you have connected the serial cable .  It should be either 1 or 2.  If your computer has A and B, A=1 and B=2.

To connect a straigh key, pin 4 and pin 6 of a standard serial cable go out to your key.  You can find these wires through the 9-pin adapter by performing a continuity test.  Read the help file that is installed with CW Communicator.  It should be located here: 

C:\Progam Files\ MRX Software\CWCom\Help.htm

Near the bottom of that page will be directions on connecting a paddle/mouse/sounder using a serial interface.  Yes, you can connect a sounder!  Refer to the circuit provided in the helpfile for building the interface.


Changing Transmit Settings

About the only setting you want to change would be the character speed of what you are sending.  Select the "Transmit" tab of the Configuration menu.

By default, the Character Speed WPM adjusts to what you are sending.  If you are using the translate feature, you may have to tweak this feature.  This program is quite strict on timing.  If it reads your dits and dahs incorrectly, it will not translate correctly on your side and on the receiving side.  This feature is quite nice if you need to practicing regular timing when sending.  It can be a nuisance when you are an experienced operator.  For slower speeds, I have found that you should choose the "Lock" option and bring down your character speed to about 5-10 wpm.  Any higher than that at slower speeds and the translation feature will not work properly.  Remember, the computer is better at counting than you...i.e., it's timing will be perfect, while a human's never is.  The only other way to get around this is for you to use a bug.  For USMT operators, I would strong suggest you DO NOT use a bug because we use straight keys in the field.


Sending CQ

If all goes well, once you are properly configured and you successfully connect to the server.  You will see the screen below if you connect properly.


Once connected, send CQ!


Who's Connected?

Click on the menu button for current users.  It's the button second from the left as indicated previously.

The connections are shown for the channel you are currently connected.  If you change channels, close this window and open a new connections window to see if anyone is connected.  The current time is shown at the bottom of the window.
