Flex-1500 Uploading 630m WSPR Spots

Since adding this homebrew elliptical MW bandstop filter to eliminate nearby AM Broadcast overload, I am now able to upload 630m WSPR spots received on my Flex-1500. The filter does not affect its regular HF operation on 80m and above. http://www.qsl.net/kp4md/mwfilter.htm The antenna is a 40m Loop SkyWire fed with 300 ohm Ladder Line.
