Hi Scott,
Thanks for the info I will give it a try.  Also if I get some time today 
I will set up a signal generator as Joe suggested and try to figure out 
what's going on.

Previously I ran the MFJ box and used a TH11 as the secondary antenna, and had super results..But on the Anan 200D all I basely get t is the ability to play with amplitudes and never can find that sweet spot for noise elimination..Not sure if tis question should be directed to Anan or HPSDR>
