As a new convert to CQ100, thanks to the article in 'Radcom', I had to put in my 5 penorth and say what a marvelous system it is. I've no HF gear, and very little room for antennas anyway. I like to chat to people rather than construct etc, so CQ100 is ideal for this.
As a matter of interest, I have been doing some mobile operating by parking outside my local MacDonalds restaurant, who kindly provide free wifi and connecting my laptop. Great stuff!
