[hpsdr] Excalibur Finished - Some Questions

[John Westmoreland]

HPSDR,

OK - have finished building Excalibur and am getting the green LED - and it
is up and running on my rig.

I will calibrate it once I borrow Don's (ARRL Ham of the Year) rubidium
standard.  But should be +/- 1 Hz as is.

I do have a question - I have noticed 10MHz spurs and harmonics picked up a
bit or seemingly have.

I haven't implemented the extra grounds on Alex yet - does anyone know if I
implement those grounds if it'll kill the spurs?

Another question - should the unused I/O on Alex have 50-ohm terminators
installed?

73's,
John
