After losing some hair and some advice from others and a bit of help from Google I managed to have it up and running in a few hours. Several parts of software are required to get this going and they all have to tie in with each other. First is the receiver software called SDR Play, then you will require Virtual Audio Cable to patch the Audio through to PDW Paging decoding software.
Most of the settings are self explanatory but the clincher to get it going was in SDR Play to click the setting cog at the top of the screen and select the Sample Rate of 1.4 MSPS and it all fell into place.
I am now receiving my own pager messages on the computer and PDW can even forward them to my new mobile phone, if it ever arrives. If anyone has any questions relating to setting up PDW with the SDR Dongle they can contact me via my contact page.
