If you're expecting it to work as a graphical VSWR meter, with another
rig (the BITX) sadly that's not how it works.
The Antuino is a stand-alone instrument in it's own right.
If you have transmitted into the Antuino, you may have damaged it by now.
You'll also find, you can't receive much (if anything) other than the
Antuino's own signal source. That is normal.
