I ended up building a W1VLF,  AM BC filter for KA1GJU Super Station #2, since that server is the only one with an SDRPlay RXR. All others got destroyed in the lightning hit of 2019.

Here's a link to Paul's video:

For those with short attention spans, skip out to 05:10 to see the RSP2 using the external filter, no external filter, and the RSP2 internal AM/FM BC filter.

YMMV
