OS X USERS: OS X cannot emulate serial ports. RUMlogNG is the only supported OS X logger because it can do CAT over TCP instead of serial.


N1MM Logger is a popular contesting and DXpedition logger. This tutorial covers N1MM Logger+, which can be downloaded here.

Launch N1MM and go to Config -> Configure Ports, Mode Control, Audio Other… 

Configure a radio with these settings:

  • Port: The HIGH virtual COM port, the opposite of what was configured in the RHR helper above. For example, if you selected COM17 in the RHR helper, select COM18 here
  • Radio: Elecraft K3
  • CW/Other: checked

Click Set and configure your radio exactly as follows:

  • Speed: 9600
  • Parity: N
  • DataBits: 8
  • Stop Bits: 2
  • DTR (pin 4): Always On
  • RTS (pin 7): Always On
  • Enable Both Hardware & Software: checked
  • PTT via Radio Command Digital Mode: checked
  • PTT via Radio Command SSB Mode: checked
  • PTT via Radio Command CW Mode: checked

n1mm config

If N1MM is running while you are not connected to a remote station, then N1MM will complain that it cannot communicate with the radio. This is expected. You will see the dialog below; just click Retry.

Ham Radio Deluxe

Ham Radio Deluxe likes the radio to be turned on BEFORE it is launched. You must connect to an RHR station first, before launching HRD.

In the Connect window, configure:

  • Company: Elecraft
  • Radio: K3
  • COM Port: the HIGH virtual COM port (COM18 in our example)
  • Speed: 9600

After you have connected to a station, click Connect.

Once HRD has started, you can reconnect to different RHR stations and HRD will follow the radio without complaining.

hrd connect



Go to Setup -> Radio -> Radio 1 configuration.

  • Port: the HIGH virtual COM port (COM18 in our example)
  • Baudrate: 9600
  • Radio: Elecraft K3

RUMlog is now configured for the RHR Helper. On the main logging window, the kHz and Mode labels will be either red or green. If the labels are green:

then RUMlogNG is connected to the helper app and is ready to track radio data.

If the labels are red:
