Using the MFJ-5008 to listen for Wildlife!

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!

Hunter S. Thompson would be proud ;-)

Great review. Needs more bat clips. Take a trip to Austin.

 

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!

 

That's was really cool, thanks for sharing!

 

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 73

 

Wunder how deep the POOP is in that cave........Bob N9RMA

 

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

Thanks for the fascinating combination of nature and radio. Now I want to take a trip to the bat cave! -Roy (wa2ikx)

 

Johnny, You can have even more fun with that parabolic reflector. Epoxy a regular microphone cartridge at the focal point and connect it to a high gain audio amplifier. Now you will be able to hear all of the wildlife in your area like you've never heard it before. You will be amazed.

 

Wow, that's a lot of mosquitos!

My dad called trout "textured insect protein"

 

Used to go to "Bat Cave" 35 years ago when the "admission price" to the
rancher who owned it, was a pint of Jim Beam.
The Mexican Free-tailed bats there can number 50 million when they are nursing young.
These bats feed mainly on moths, saving farmers millions in crop damage.
I live only 6 miles from the cave, and can watch hundreds feed among my huge
pecan trees nightly.
