BTDT

Just lower your gain, the receiver is mixing close signals and cross modulation.

Make a round of tests to check what gain level gives you better results.

My experience:

• I have a near police station with a powerful 150Mhz  station, any higher than 40 dB will give me splatters
• Also I have a neighbor ham with an co-lineal and 50W about 400m (line of sight between antennas), if he is active on 2m local on high power gains above 28 dB will ruin my reception.

That's my experience.

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?

BR Andy
