    Testing out the MFJ-5008 Ultrasonic Receiver w/ Parabolic Reflector at Bracken Bat Cave in Central Texas! Bonus visit to Natural Bridge Caverns included!

    The MFJ-5008 isn't just for identifying pesky power line noise & mechanical noise, but can also be used as a 'Wildlife' Noise Detector! Bats & all sorts of other creatures that emit sounds in the ultrasonic range.

    Stay tuned to SignalSearch for more videos on the MFJ-5008, including investigating some pesky power line noise & other culprits that make your ears go ARGHHH!

    Just remember that bats are best NOT touched, as many species harbor disease (for humans). Best to respect them from a distance. And bon appetit on the bugs!

    Thanks W1YW & W1XQ! Stay tuned for the 'Powerline' noise investigation video! I think my neighbors are starting to think that I'm trying to listen into their conversations with this thing though :p 73

    LOL! Interesting enough, scientists have used 'electrical pulses' to try & determine the depth of the guano in Bracken Bat Cave - they estimate it's around 60 feet deep. The smell is pretty pungent as soon as you get near the cave! Phew!

    Great presentation! Topics such as this are a nice “melding” of scientific topics/curiosities and is exactly what we need to bring more youth into our hobby

    Best of 73
