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.

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. 73, Matt VK2RQ Envoyé via Outlook Mobile _____________________________ From: John Lawrence via Elecraft <elecraft@mailman.qth.net> Sent: vendredi, février 5, 2016 4:45 PM Subject: [Elecraft] KX3 IQ ADC and IQ DAC specification? To: <elecraft@mailman.qth.net> 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?
