For non-critical AM listening it is certainly possible to use the 2.7 KHz roofing filter - particularly if you do not have either the 13 KHz (FM) or 6 KHz (AM) filter. As a test I disabled my FM filter and using the 2.8 KHz filter with the DSP set to 6 KHz, I get perfectly acceptable performance on the MW band - particularly if I tune 1.3 - 1.4 KHz high/low for "single sideband, full carrier" detection. Music certainly is not as "bright" as it is with the 13 KHz filter but it is not bad enough to send me screaming from the room. Voice performance/quality (e.g., a ball game) is quite satisfactory (at least as good as a common "table radio"). 73, ...
