Its seem as if things came to head the last few days, my Digimaster interface seemed to stop working , the antenna went high swr and the laptop , which is very old, ground to a virtual halt.
Starting with the digimaster: this was attached to the rig and computer and when I went to look at it, had stopped receiving data, after spending 60m in skype, with one of the people who runs the forums for digimaster, it still was not working, so it was sent back to the maker.
The Maker revealed that one of the leads had become faulty, with a pin being bent out of position. it was duly replaced and sent back to me.
So I have replaced the laptop and set it up with the Digimaster, I now have a Asus X55C, which is a very middle of the road laptop, but, its the best I could manage to get back on the air.
The swr problem was caused by a bend in the coax, which was strengthened out, so hopefully that's it for a while, as this is expensive.
