I have to confess, I have not tried "virtual" ham radio for many years. It is a poor substitute for the real thing. Even with my poor voice these days, the real thing offers so much more. Nonetheless, it will appeal to some, especially when HF conditions are poor. I expect this will become more popular in the next few years. As it name implies, virtual ham radio uses the internet rather than the ionosphere as the medium of "propagation". If all you want is to chat, this may be for you.
