Even though it is an 8 pole filter which *theoretically* has zero offset, you may have to apply some filter offset in the filter setup menu. You can just guess, or you can use a broadband noise generator at the antenna input and look at the audio output with an audio spectrum analyzer such as Spectrogram running on a PC to see where the filter passband is placed. The amount by which it is offset from the frequency set in the sidetone pitch menu is the amount of offset that should be entered.
