I have been working on a design for a CW rig for 40 and 20, with more than one eye on use for SOTA activations. I have also being using simulators to test the design so hopefully I only need change a few resistors on a real world prototype to bring this thing to life.
I am getting excited to bring this thing into the world, as I expect it should do much better than a FT-817 on CW.
Posts on my blog if you are interested.
I have also started up a Yahoo Groups to discuss this and my other projects, a audio interface, masthead preamp and preamp sequencer. Link at: http://au.groups.yahoo.com/group/vk3wam_devices/
