The function of Spur Reduction is to move (not reduce) internal DDS spurs outside of the RX passband so they do not interfere with reception.

I have done some work reducing rf in the shack, mainly by taking the 6m antenna out of the SGC mac-200 atu and putting it via a coaxial switch, and moving the internet router / switches away as far as possible... switching these off reduces spikes greatly. However there are still some, and someone mentioned that do they move with SR on or off, the answer is yes some do, some disappear as well. Not a very technical explanation I know, so, what is the significance of thespikes moving with SR, and can it be reduced / fixed ? p.s. also I notice considerable audio noise when scrolling the panadapter, either via mouse but more so by Powermate It should be noted that I believe the lower bands are fine. 73 Steve G6HOQ _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
