Setting up an Icom IC-706mk2g for WSPR with Tigertronics SignaLink USB

Icom IC-706mk2g with Tigertronics SignaLink USB

Drivers: Firstly I installed the SignaLink USB as per the Tigertronics instruction manual. Installation depends upon the Operating System being used but everything is described in detail in the manual, on the Tigertronics website and downloadable manuals.

The laptop (Windows XP) shows the SignaLink as USB Audio Codec which can be accessed via the sound card settings and progams that require them, such as WSPR.

Sound Playback and Recording properties may also need to be checked and levels adjusted to ensure optimum performance. Simply click right on the speakers icon in the task bar, or from 'Sound' in the control panel, to access this. From the 'Playback' and 'Recording' tabs you'll see the different devices installed in the computer; in each identify the USB Audio CODEC being used for the radio, right click on it and select 'Properties'. Levels can be adjusted from here if necessary.

WSPR Program: Next I opened the K1JT WSPR program. The program can be downloaded from here and once installed a shortcut will be placed onto the desktop:

A console window opens followed by the GUI window. Click on Setup --> Station Parameters and enter the appropriate station parameters - the port numbers for Audio may vary from those shown below depending upon the individual PC:

Call : M0MTJ
Grid : IO82VO
Audio In : 3 USB Audio CODEC
Audio Out : 7 USB Audio CODEC
Power dBm : 37 (i.e: 37 dBm = 5 watts; 33dBm = 2 watts; 30 dBm = 1 watt)
PTT Method : VOX
PTT port : None (not applicable for VOX)

Since I use VOX as the PTT method, I left the Enable CAT box un-ticked and all the other settings blank.


In the WSPR user interface, ensure that the Upload Spots box is ticked. This will then ensure that the program uploads any other WSPR stations that it receives to the WSPR website as 'Spots'.

While the frequency must be set in the WSPR GUI window, the program does not control the radio. Therefore the radio must be manually and accurately tuned to the correct frequency. Refer to the table below for the correct transceiver dial setting.

Once everything is set up, save the Station Parameter settings from the File Menu. The program will Wait. After a while it will begin Receiving - listening for other WSPR stations. Then it will transmit for a couple of minutes, before returning to Receive.

I hope that all helps a bit! 73, Mike. M0MTJ
