Digital modes

It has been a long time since I have used digital mode. So I bought a signalink usbinterface.
Now I can make a restart in digital modes.

An old pentium PC was available for the coding and decoding. The transceiver I use is an old ICOM IC-730. I also have an IC-817 this one works ok but the IC-730 has a better receiver.

A lot of nice freeware programs exists. I have chosen fldigi for most digital modes. Fldigi does not support all modes so I use different programs for modes  WSPR,JT65 and ROS.

For a while I thought that the signallink was partly broken. It worked fine for most programs butI did not see a signal on the right input. It turned out that is was normal as the signallink is a mono device. Unfortunately one of the JT65 programs could not be used because of this. I read that the developer is going to update the program because of this issue. In the mean time I use a different program for JT65.

The modes That I use are: WSPR, PSK31, JT65 and ROS.
