About the Ubitx
Technically, Ubitx is very well

Tinkerers and hackers are welcomed, as
well as any user who desires to build or
modify the Ubitx.
The first signal that sputters through the ether, past
your mess of wires, into your ears, and out of your
hand into space, is stuff of subliminal beauty that is
the pleasure of the home-brewer alone.
