    Video receiver

    Hello
    I´m designing a receiver for rf video signal using an old analogic tv tuner , my doubt is if after the ic video demodulator it´s necessary a circuit for modulate the signal to couple in a RCA composite plug , like an DVR or old TV.

      Re: Video receiver

      the LM1889 is used to create an RF that can be input to an antenna of a TV. If you are sending the video from the TDA2549 to RCA and wangt to modulate the video again ( like change the RF frequency to channel 3/4) or the like then you would use the lM2889.

          Audio video receiver KENWood KR-V990D,no sound
          by JRade
          When I select the FM receiver, I find a radio station, the sound is heard on REC OUT(L,R), REC TAPE1(L,R),REC TAPE2(L,R) on high-ohm headphones, the sound regulation does not work.
          The output reacts when I connect the record player to PRE OUT FRONT L, the sound is heard in the speaker but the sound regulation does not work. Then it does not matter what I chose on the front selector.
          I replaced the capacitor C303/0.047F, nothing changes.
          I'm asking for help, what should I do next?
          Thanks in advance!...
