    Has anyone ever opened up their patch antenna and located the ADC used for the 400MHz Blackfin DSP?

    I've been trying to spot it on the FCCID photos and it's not easy to see when I zoom in.

    FCCID Photos: fccid.io: VIP201412 Stinger VIP Teardown Internal Photos Carcomputer B.V.

    For example the Max uses this ADC: ADC10040 10-Bit, 40-MSPS Analog-to-Digital Converter (ADC) | TI.com

    Which must do the job pretty well since it's using software defined radio techniques to sample the IF's directly.. what we've been referring to as a "digital detector". I have a feeling the Uniden R and Stinger VIP are DSP units in that they don't directly sample the IF and use an FM demodulator, or maybe some other novel technique, but do rely on a relatively powerful DSP's for processing signals as we all know.

    Stinger marks the boards really nicely and I'm trying to get a very basic idea of how they do things because it will likely shed some tiny amount of light on how the Uniden R works, and in general talking points about "digital units" and designs which rely on a dedicated DSP for signal processing rather than one CPU for everything like every other unit.

    Well I'll be darned if I can find it. Now my eyes hurt.
