Re: LAA+ FM broadcast interference using SDRplay Bias-T but goes away using 12v Bias-T power inserter?

Chris answered your question.

To help stop intermod from strong stations the amp likes 12v rather than 5v.

As you have noticed it goes away when using 12v..so may i suggest you use the 12v tee rather than the 5v from your sdr.

This is not a fault with the ccw amp but is down to how the amp works..it is the same with many high end loop amps..they need full working voltage to “ reject” interference from unwanted signals..all my loop amps run at 12v..

Some people can get away with using 5v. Some can not..
