If Elecraft are marketing the KX3 as anything other than a trail radio
the design missed the mark by 5 km. Given the under powered speaker,
lack of headphone amplifier, and lack of separate line in and line out
audio connections, the rig is severely lacking is the "home station"
department - particularly for digital (RTTY/PSK/JT65/etc.) operation.
Further, with a SIS-570 based local oscillator and direct conversion
the jury is still out as to whether the phase noise/reciprocal mixing
performance is sufficient for use in strong signal (receive) and high
power (> 10W) transmit environments. Unless SiS have improved their
products greatly or Wayne has some magic in his implementation, I am
very concerned (witness the phase noise in the XG3).
