Phil, quite interesting, and congratulations for this new achievement. Is the 100 kHz lower frequency limit dictated by some constraints, or would it be possible to go down to e.g. 500 Hz, as the SDR-IQ does ? That would be quite interesting both for ELF/VLF/LF reception and for other uses, like bat detectors, etc. And, have you fixed any tentative price range yet ? 73 Alberto I2PHD
