Still investigating the EeePC and Ham Radio I have about concluded my investigations into what can be done and how I would approach the subject if I had one.
Much talk is of using Ubuntu external to the Eee. On a USB Hard Drive this may work, no tests done at this end.
Full Ubuntu running on a USB Stick I have tried. Using the method available Ubuntu is not like the Debian Install in my previous post, it soon starts to run too slowly as data clogs it up. Just like Microsoft, only it happened much faster,
The cut down Ubuntu version will need installing in place of the Xandros on the SSD Memory. It seems to run OK and I have used Fldigi Multimode on it on my Desktop Computer.
Here is the Desktop.

Installation in the absence of a USB CD Drive would involve installing Ubuntu on a USB stick and installing to the SSD from there.
I see no reason why it should not work, I actually have got to like the Live USB version I am running.
Here is Fldigi on air, it runs full screen.

I have tried WSJT and it crashes, this is normal for Ubuntu, if the 'Linux Gurus' cant sort that then I am not going to try.
I tried the G4ILO compilation of WSPR for the EeePC, that fails demanding library files I couldn't find for download, I won't spend too much time on it as any changes I make are lost on switch off on my version.
The Internet Browser is Firefox, like all the Linux USB installs I have it goes like a rocket. Here is my blog, previous page, full screen grab.

That about concludes what I can do without an actual machine. I am surprised that there does not seem to be more from users on the web.
Yes good work Eddie, for just about anything except the
preinstalled programmes you need Ubuntu or something
similar. It should be easy by just replacing the delivered
solid state hard drive with another.
