You can reduce the KX3's VFO signal leakage to another receiver nearby by setting MENU:RX ISO to ON. Yes, it is similar to direct conversion, except that there are two channels (I and Q, like other SDRs), allowing for image rejection. The KX3 uses this architecture rather than superhet to provide the SDR feature, as well as to reduce the number of stages, allowing the unit to be very compact. 73, Wayne N6KR ______________________________________________________________ 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
