Does an RTL-SDR usually lack a passive/monitor mode?

  RTL-SDR refers to repurposed USB TV tuners using RTL2832U chipsets. They do not have any transmit ability.

    It's possible, but hacky and not that useful [0] [0] https://www.rtl-sdr.com/using-the-rtl-sdr-as-a-transmitter/ https://www.rtl-sdr.com/using-the-rtl-sdr-as-a-transmitter/

    They do however leak their local oscillator through the antenna, albeit at really low signal levels. Two ham friends experimented with slow FSK across the room.

  RTL-SDR dongles cannot transmit. They are receivers only.
