Just been rattling around the 'net and I stumbled on HamSphere , which is a sort of web-based shortwave simulation.
Downloaded the software and registered for an account (you get a free 3-day license - no idea what the costs are after that) and was soon running a simulation of a modern transceiver...
There's DSB voice mode (presumably for those with too much to say) but also CW!
I heard a CQ from 2hs413 (HamSphere can issue its own "call signs") and answered it - it turned out to be Scott in Michigan. Soon after that, Sam, vu2usa called me from Bangalore.
Don't get me wrong - this is never going to replace the "real thing". But it is one hell of a good game when you're stuck in a Hotel on the other side of the world on a business trip (ZL, in my case). All you need is your PC and your internet connection.
I just need to figure how to hook up a key to let me really send morse (rather than have the computer interpret keyboard input).
