Hence the need for the huge "cray-like" computational power. 73, Scott AC8DE

The 6x00 receivers actually receive the ENTIRE 30kHz-76MHz spectrum AT THE SAME TIME. That's right -- THE WHOLE ENCHILADA! The "slices" just "carve out" a small piece of what has already been received and then provide that to the operator on-demand. The older radios only receive the span equal to the sampling rate and then that is tuned (by hardware DDS) to span the part of the spectrum you want to receive. Imagine that difference between looking at the world through a porthole vs. going up and standing on deck so you can see in all directions at once. That is the big difference between the previous QSD-based radios and the DS/DDC radios of the 6x00 series. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 [email protected] +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
