Watch out!
LNAs can do more harm than good for IN BAND strong signals.
Hartwig 144-149mhz LNA solved my RFI problems with my SATNOGS station.

Hi,
I received many pictures from ISS. I'm using RTL dongle 2832 with SDR# program andMMSSTV 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 fromof transmitter which is far away from 145.8MHz but still in the 2MHz bandwidth of RTL2832?
BR Andy
