fldigi Question

I have a Flex-6700 running SmartSDR 1.7.30 and am using fldigi 3.23.09. I have downloaded and copied the XML files dated January 2016 to the appropriate location on my PC and have selected the XML file for Slice A in fldigi and I am using a single slice in SmartSDR.

I am able to make contacts just fine using a wide filter such as 2x4 or 2x3 in fldigi. If I want to QSY to the "sweet spot" of 1500 Hz, I just hit the QSY button and the signal of interest is centered on 1500 Hz as expected. If I then select a narrow filter, the filter is NOT centered on 1500 Hz and I, of course, cannot copy the signal. My question is therefore, how can I get the filter to center on the sweet spot so that I can take advantage of the narrow bandwidth? 

It has probably been a year or so since I have used fldigi, so am I forgetting something or is there something about SmartSDR 1.7.30 that has changed how the XML files work?

Thanks in advance for your help!

Tim,

The last time that I used Fldigi, I do not think the DSP Offset was available in SmartSDR. It was defaulted at 0...I changed it to 1500 and the filters are centered.

What is changed besides Fldigi with the DSP offset set to 1500?
