I am still waiting for my new house to be finished after which my station will be set up. So whilst kicking my heels I decided to get to grips with the changes to Amateur Radio that have taken place over the last 30 odd years. 

I have been reading up on FT8 and decided to try it out (receive only) using a web based SDR (Software Defined Radio) and the WSJTX software (Weak Signal Communication Software).

It was far easier than I expected. I installed the WSJTX software and found a reliable web based SDR. After 30 minutes of playing with the SDR I set it on 14.074 mHz (the FT8 frequency) where I could hear non stop FT8 traffic (I assumed). 

I then configured the WSJTX software thai I had installed earlier, I left all the settings as defaults but needed to do a bit more to pipe the audio from the web browser where the SDR was running in a tab to the decoding software. 

After installing a Virtual Audio Cable in my PC it was easy. I just went in Windows settings and set my output audio device to the Virtual Audio Cable. Then in the WSJT software I went into settings / Audio and set the input to the Virtual Audio Cable.

That was it. I restarted WSJTX and it started decoding traffic received by the SDR in milliseconds.

I could not believe that it had been so easy.

Also needed is a good time sync program (essential) for your PC. The windows default is not good enough. The link to the one I use is below.

Links to the software and the web based SDR I used are given underneath the image..

My computer runs Windows 10 64 Bit. Be sure to download the software version for your particular set up.

I could do a walkthrough of the various steps but if I managed it without one I am sure you can :) Please feel free to leave a comment.
