My BC396XT seems to have trouble detecting the 127.3Hz PL tone from a couple stations. It tends to be in and out a bit. I thought it might be the transmitters, but all my other capable radios (2x BC780s, BC296D, Kenwood TMG707A, and Yaesu VX7R) have all detected it with no problem. So far it just seems to be this one tone. Has anyone else had any issues with this or any other tone? I'm wondering if its just a defect in just this particular scanner or common with this model.
