  • HackRF spectrum cleanliness tests

    From Ivan Mikhalev@1:154/30 to All on Tuesday, February 23, 2021 02:35:47
    I have finally tested the HackRF for spurious emissions, and I can say it is definitely acceptable.

    With SDRAngel acting as the IQ modulator, I got really clean performance on 40m. There is a DC spur at IF center though, so offset tuning should be used.

    Wideband spur emissions are minimal, shouldn't interfere with anybody on HF. Yet to get reception reports though, as now I have no license and no suitable power PA.
