[amsat-bb] SDR# settings for AO85?

What are the optimal settings on SDR# (e.g. filter, order, bandwidth, etc.) for downloading AO85 DUV data? I used to get 20 or so data payloads on a good pass, now I'm lucky to get 1 and I can't figure out what the difference is. Any constructive help would be appreciated. Thanks!
