[AMSAT-BB] SSTV with SDR RTL2832

Hi,

I received many pictures from ISS. I'm using RTL dongle 2832 with SDR# program and MMSSTV with virtual cable and Orbitron.I found many rainbow lines on pictures and I analysed that this is the case of transmission with APRS local stations around 5km away and 1mhz below my receiving. Anyone have experirence of good filtering or set the SDR# program to reduce the infulence from of transmitter which is far away from 145.8MHz but still in the 2MHz bandwidth of RTL2832?
