I'd like to be able to use an external ADC. In my environment Bluetooth has proved to be very unreliable, and per the manual only the Bluetooth channel allows samples to be continuously streamed). The USB link is very reliable but doesn't support streaming.
I hooked up an audio interface to the speaker input (via an audio transformer/DC blocking capacitor) but there's a lot of noise (the noise appears to be there on the the original speaker output, just more difficult to hear from the speaker).
I imagine what I could do is leave the board jumpered to use the onboard IF filter, and sample at J7.
In any case. Is there a schematic available? I could not find one, and while I could stare at the board some, it would save some time. :-)
Thanks,
