	The RadCom review is only available to RSGB members
online.  Same for ARRL which just published their review
of the Inrad roofing filter for Members Only here:

Bottom line: it helps IMD and BDR for 5 kHz spacings,
but not much for 1-2 kHz spacings, as you would expect
since these signals still fall within the 4 kHz bandwidth.
