Jack,

OK, now that you have put some numbers on your interpretation of 
"affordable", I understand.
To many, the KX3 *is* affordable.

I differ with your interpretation that an SDR does not need a front 
panel or physical controls.
It may or may not have those controls and still be an SDR.  See the 
definition of SDR at Wikipedia.  The KX3 is a direct to baseband SDR 
transceiver.

Yes, the Funcube is interesting.  It fits within your price target, and 
I recommend it to you if it will do all that you want.  You may want to 
compare the KX3 dynamic range and other receiver parameters before 
making a final decision.  There is a reason the KX3 is rated very close 
to the top of the Sherwood ratings.

73,
Don W3FPR
