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? 73, Dale WA8SRA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
