The KX3's direct-conversion/quadrature (I/Q) receiver works with or without roofing filters. You could certainly start with the basic unit and add the roofing filter module later, if necessary, for your operating conditions. In fact, the KX3 is the only transceiver of this type that we know of that even offers a balanced roofing filter in the receive I/Q path. It's been a challenge, but we the results will be worth it. Adding this module makes the KX3's receiver perform more like a superhet, with better blocking and IMD dynamic range. But it will retaining the advantages of I/Q demodulation, including very flat passband response, fewer mixing spurs, no-tune RF filtering, and the ability to use SDR (software-defined-radio) applications. We'll clarify all this when we update the KX3 brochure. 73, Wayne ______________________________________________________________ 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
