Matt
Thanks for your suggestion. I am trying to understand what it took to reach
this level of SDR performance knowing the specs of the IQ ADC on the receive
side and IQ DAC on the TX side of the archritecture of the KX3. Current drain
isn't my concern except in the case of the KX3, it must be able to support
battery use in the targeted application. I'm hoping a factory response is
received too.
Thanks John

Judging by the anti-aliasing filters, I would guess maybe 48k samples per
second, 24 bits per sample. Could be higher at 96k which could reduce noise
slightly via decimation, but that would probably consume extra power and not be
worth it. But does it really matter? That is all internal to the radio, and is
not exposed on any of the external interfaces.

I am trying to determine the IQ ADC and IQ DAC specification in the KX3. I'm
interested in
determinng how many bits and the speed...Bit resolution and samples per second?
Thanks
John, W1QS
