[QUOTE="bicter, post: 536379, member: 1240"] Yes, you can build an audio booster/amplifier quite cheaply. Where the costs start to rise is when you start introducing variable/switched filtering, companding(I'm pretty sure the Spo1 has this), signal modification and the ability to work with a variety of detectors. Steelphase appears to have got it right with his "Enhancer" [/QUOTE]
