    I just received my RTL-SDR from China. I installed Cubic 0.2.3 and want to monitor the 20 meter USB Ham bands.
    I wonder if someone could jump start this 84 year old Ham, using Cubic on my iMac?

    David, my RTL dongle will not work below 24MHz. Its basically a VHF/UHF device.
    Not sure about yours but these things are all pretty similar.
    Sorry but never used anything Mac.

    CubicSDR is now at v 0.2.4.

    Current version at:
    https://github.com/cjcliffe/CubicSDR/releases/tag/0.2.4 (you'd want "CubicSDR-0.2.4-Darwin.dmg" from the list.

    Release notes at

    User manual at:
    https://cubicsdr.readthedocs.io/en/latest/index.html

    The user manual provides far better information than I could to "jump start" you.
    Depending on what flavor RTL-SDR module you have, you may or may not need an up-converter to receive HF signals like the 20 meter or any ham band through 6 meters. I have the NooElec NESDR, which natively will receive 25-1750MHz, with a NooElec Ham It Up up converter in order to copy signals .1MHz (100kHz) - 60MHz. When using the up-converter, all SDR software provides setting an offset frequency (-125MHz for the NESDR/HamItUp) to allow correct frequency readout of the up-converted signal.

    FYI other SDR software to evaluate are Gqrx, SDRdx and SDR Radio
    Good info on software and hardware combos at rtl-sdr.com
