SDR-Touch to look at signals from PLB and MOB beacons

Using SDR-touch on my Android phone and a cheap softwared defined radio to look at the spectrum of the signal on a Mcmurdo Smartfind PLB. We look at the 121.5MHz homing signal and the test data burst on 406MHz.

Same thing with a Sea Marshall SMRS8 Man Overboard locator beacon on 121.5 and a test beacon on 121.65MHz
