I really hope that this does not apply to received audio to the 
headphones or loudspeaker!   I just purchased two FM filters (one for 
sub-receiver to monitor wide splits) specifically to open up the receive 
passband (audio included) for SWL and BCB reception. I have no intention 
of actually transmitting FM or AM for that matter -- just want the wider 
audio bandwidth for receive.

So... is the received audio bandwidth *really* limited to 4 KHz?
