Hi all,

New to the list, intro and 1st question:

de AD0ES
Name: Steven
QTH:  Boulder County CO

I just finished assembly of an atlas/metis/mercury.  Unfortunately it appears to be deaf.
Using alphaDelta ultra ant:

<<< QtRadio screen-grab removed as too large for list:
almost flat line below -110dBm, large spike just to left of dial frequency,
mirror image set of random vert/horz tracks centered about 240kHZ either side of dial frequency >>>

If I inject a sig-gen @ -33dB the 2 sets of tracks to either side disappear but the center image remains, without he
tone showing up.  Enabling DC block removes the center spike from spectrum (but still yellow trace on waterfall),
but no other diff.  I have also tried powerSDR/win7 with similar results.

I can see data/commands going both ways thru chain of hsdrserver/dspserver/QtRadio. Looking at UDP packets
straight off the metis I see a LOT of zeros:

<<< wire shark screen-grab removed as too large for list:
almost all: 00 00 00 00 00 00 03 00   00 00 00 00 00 4[9-a] [xx] 00 >>>

Unfortunately my Agilent is back at the factory for warrantee repair, so I can't checkout
the analog path at the front end. A summary examination of the components with a fluke
exposed no worrying shorts/opens.

Any theories?
