[Elecraft] Simple spectrum analyser for SSB TX testing

[Dave G4AON]

For those who are eager to build something while waiting for the courier 
to bring your K3, you might like to try a simple spectrum analyser. In 
the best traditions of amateur radio this can be built in a few minutes 
using parts from your junk box. All that is required is a computer with 
sound card and a signal generator or at least a oscillator of sufficient 
level to feed a diode ring mixer. Details at http://www.astromag.co.uk/ssa/

Now you can check out your K2 with a two tone test!

What do you think?
