Or reference the signal identification page around the internet to hear p25 digital voice and p25 encrypted voice audio and compare to what you hear

Antenna placement and coax length could be playing a part as well. The dinky little antennas that ship with the rtl dongles aren't terrible but setting one up indoors and probably next to or on top of a pc that's spewing all sorts of noise could dramatically affect reception. Also if you're connecting your antenna through a coax cable that's rolled up into a coil it can affect your signal. if your coax is too long, dont coil it up. Just stretch out the excess.
