In general, DRM decoders expect a receiver IF of 12 kHz and a bandwidth of up to 20 kHz. The K3 can provide neither without modification.
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. Some DRM decoders are free, others require a licensing fee. WinDRM is different, being a mode designed for Amateur radio use, primarily for digital voice but also for file transfer. 73, Lyle KK7P ______________________________________________________________ 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
