Since the 7300 uses direct sampling, it will have the same blocking dynamic range (BDR) problem as other radios in this class, especially multi-signal situations such as contesting. I also doubt it will beat the KX3 in close-spaced dynamic range, unless they used a very exotic, very expensive A-to-D converter. (Note that the only way the Flex 6700 series can achieve good close-in dynamic range is by turning on the preamp. This overcomes the very poor preamp-off MDS, but at an even greater cost in BDR.) Beyond that, the KX3: - is about 1/5th the size - is about 1/5th the weight - consumes probably 1/10th as much RX-mode current - has an internal battery - has an attached keyer paddle - has built-in stereo audio and CW/RTTY/PSK31 text decode with a PC - works with integrated peripherals (PX3 and KXPA100) that can be left at your fixed station when traveling So if you're operating portable, it's an apples/oranges comparison. 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 Message delivered to [email protected]
