[hpsdr] Hermes/ANAN-10 RX spurious signals?

[Bruce Beford]

Thanks, Dick.
I am glad you have had a chance to experiment with this a bit. I won't be
able to work with mine for a week. Please keep us posted on your
progress/observations.
73,
Bruce, N1RX

Since the position of the Hermes board in the case seems to affect the 10MHz
spur, I tried putting the Hermes back in position and sliding bit of
shielding over the A/D  area, about 1/2 spacing above, not grounded. This
reduced the 10MHz spurs by about 2 S units. So it looks  like some shielding
is needed over the analog section.

I'll look into making something more practical that can be grounded later on
in the week.
