Sorry to the extremely long delay. Here in the US baby monitors transmit in the 49-54 MHzMegaHertz (MHz) 10^6 Hz band, and there just in NFMNarrowband Frequency Modulation, and it's a mic. Usually heard up to a mile away. Once had my scanner out front and was tuned to 49.83 MHzMegaHertz (MHz) 10^6 Hz and heard a baby crying inside my next door neighbour's house. Ywsia1.

This is not in USBUpper Side Band Modulation (Radio, referring to reception and modulation mode)Universal Serial Bus (Computer, referring to USB Ports and cables), but FMFrequency Modulation. You can hear the FMFrequency Modulation-carrier quite clearly! It would seem that a frequency in the 868 MHzMegaHertz (MHz) 10^6 Hz ISM band is more logical as there are many baby monitors use 433 MHzMegaHertz (MHz) 10^6 Hz ISM, 868 MHzMegaHertz (MHz) 10^6 Hz ISM and 446 PMR band in Europe. --Questor (talk) 08:09, 24 February 2018 (NZDT)
