[time-nuts] T-Bolt output harmonics

First post as a new owner & participant.

I tamed the provided switching power supply noise with some L's and C's, 
and am now looking at the 10MHz output on a spectrum analyzer. Here is 
what I measured:

10MHz   +9dbm
20MHz    -50dbm
30 MHz   -37dbm
no obvious higher harmonics
broad noise envelope at 60 > 75MHz @  -60dbm peak

Are these results typical or might I have an adjustment or other problem?

I've looked back about 6 months through the posts (is there a search 
function I've missed?) and not found anything except some 10MHz filter 
designs which I intend to try.
