Thanks for all the many comments both here an in private emails. Basically I am looking for a good second QRP transceiver to work along side my existing 12 year old FT817 that continues to work perfectly. There are times when I'd like to WSPR on one band whilst operate CW or SSB on another. Also, the second transceiver allows me general coverage RX whilst TXing on the first unit. Since I sold my IC703 to a friend the year before last, this has not been possible.
At the moment, I am still inclined to buy an FT817ND rather than the KX3. As YO9IRF said in the earlier post and on his blog, the FT817 is close to the ideal for a portable QRP radio, even after 12 years. Although it does not match the RX performance of the KX3, it does perform remarkably well, and of course it also covers the 144 and 432MHz bands and with all modes. And it is half the price.
