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.
Thanks,
Grant KZ1W
