Last year I scored - by sheer luck - a good TS-950S and I'm in radio heaven! I can't believe the amazing receive quality, the ability of this radio above all others I've ever owned to pick out a phone/SSB signal out of the forest of hash which characterizes my QTH. The audio quality is fantastic and it's so easy to listen to! Set side by side with other transceivers - including the IC-7300 I sold last year - the 950S is an absolute champion! It sails easily through the ++20 over QRM we get here and doesn't break a sweat. Recently I learned of an opportunity, albeit quite expensive, to get a clean 950SDX. The only thing I use the 950S for is chasing DX in pileups. I don't use the second receiver. I don't participate in contests. Tinnitus kept me from learning CW so SSB/Phone work is all I use it for. With this in mind, is there any practical advantage for me to seriously consider the expense in upgrading to the 950SDX over the 950S? 73s, VE3GZB.
