I'm confused. What "20 kHz bandwidth" are we talking about? The output of the detector? Are you saying that the IF in a DRM-compatible RX has a center frequency of 12kHz, and that the detector has to look at that 12 kHz IF? >Some DRM modes are narrower and can be accommodated if the FM roofing >filter (nominal 13 kHz) is installed. But getting the IF output to the >DRM decoder still requires modifications to the K3. Like what? 73, Jim K9YC ______________________________________________________________ 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
