Bruce,

I had the same experience (D3 lights but not D4).

However, I noted that with the coax in place, WWV 10.0 MHz reads 70 Hz high
(or so.) With just running the Excalibur clock on the Atlas bus, it's right
on.

wave on the upper pin of J8."

Dave, I saw this thru-hole, and intend to do the same.

"Using Mercury FPGA code V2.9, I see Mercury LED D3 lit, but not D4."

Dave, 

I have not been able to get D4 to light either. I am using Mercury V2.9, but
for initial testing ran the coax jumper from J3 on Excailbur to provide the
3.3 v clock to Mercury. Apparently, we are both missing something.

Question to the general list: Has ANYONE been able to get D4 on Mercury to
light (indicating 10 MHz PLL lock) with the new V2.9 code? (Phil and Mike,
N3UC don't count) 8-)

Enquiring minds want to know...
