Or, the INRAD 1500 Hz (actually 1625 Hz at -6 dB) which tightly protects a 1500 Hz DSP bandwidth. Configure it to engage at a DSP bandwidth of 1500 Hz. Just reduce HI CUT until you reach 1500 Hz bandwidth. (Leave WIDTH and SHIFT alone.) A narrow roofing filter is not needed to evaluate narrow SSB receive bandwidths. Just reduce HI CUT to various bandwidths and hear what it sounds like. Then, get an appropriate roofing filter to protect the DSP from strong nearby (clean) signals.
