Have a groupe of cub scouts that I want to build a "BIG EAR" to demonstrate what a parabolic dish is and does as well as have fun.
Have a Dishnetwork dish w/ LNA but can the LNA be used for audio?
PLAN = have an amp (thinking a cheap LM386 perhaps in a push pull setup for increased amplification) and a mic placed at the focal point (where LNA is located.
Using headphones and/or speaker, we can hear a conservation several hundred feet away.
any suggestions or ideas?
