One note regarding the new App - for TNA, I have my channels set at 3.9 for the Outer Channels and 2.6 for the Inner Channels. You can play with those settings to get the best fit for you. One of the things that makes these channels interesting and frustrating at the same time - they are constantly in a state of flux. Also, I like the oscillator at the bottom of the window. It works decent in conjunction with the bands.
