    Please explain to me about the following FM receiver (AV Receiver,
    Home Theater System) specifications, if possible and tell me how they
    are measured.
    Or do you know any link explaining about them?

    Tuning range : 87.5-108MHz
    Grid : 50kHz
    IF frequency : 10.7MHz ± 25kHz
    Aerial input : 75Ω coaxial
    Sensitivity at 26dB S/N : < 7μV
    Selectivity at 59/300kHz bandwidth : > 25dB
    IF rejection : > 60dB
    Image rejection : > 25dB
    Distortion at RF=1mV, dev. 75kHz : < 3%
    -3dB Limiting point : 8μV
    Crosstalk at RF=1mV, dev. 67.5kHz : > 28dB

    They are measured with a laboratory full of specialized test equipment.

    Or, if it is made in China, they just copy from a Japanese receiver manual.

    This is the point I would like to talk about.
    If it is not that essential for service technicians, it should not be
    described in Service Manual.
    Publications need to be reliable in my opinion.
    Is there any one who wishes to discuss?
    For me I need to know which one is critical.

    Regards

    Since the specs are abysmal, I doubt they were copied

    ** Google Wanker Alert !


    ** What is ?


    ** Who said that ?

    ** It is there for good reasons.


    ** Which spec is " unreliable " ?


    ** Rather talk to a stuffed toy.


    ** Why assume there is only one ?

    Gawd - what a smug, PITA cretin.
