    Hello, SIF is the position of the sound carrier offset within the specific broadcast channel. For NTSC the SIF should be set to 4.5Mhz to place the sound carrier in the correct position. Thank you.

    Need to set the CRT TV to ANT instead of CATV.

    The channel numbers on the CRT TV are just allocation slots for stored channels, not the UHF channel number. You need to search tune or enter the frequency manually via the menu.

      @@urzamaster They'll be just as the past person stored them. They're just presets. They won't correspond to anything. I was thinking, for the love of God, go into the menu and do a scan! (or enter the RF channel number as appropriate)

    You need to put an aerial into the CRT tv, as the gain of the TX is not very high so not to interfere with anyone outside your property. The 6 Mhz. setting is for the Vision and sound separation in the UK with 8 Mhz UHF channels the separation is 6 Mhz but don't know what is is in the US. Without thus being set correctly you won't get sound.

    Need antennas connected to both TV's. In America, the channel bandwidth for both VHF and UHF channels is 6 MHz; with the SIF set to 4.5 MHz. You're receiving the video on the wrong channel because you have channel width set to 8 instead of 6 and not getting the audio at all because it too is offset improperly.
    Keep playing with it, it appears to work,just wrong offsets. Good luck.

    Is it outputting a digital signal the CRT can't receive? I know it says analog on it but that may just mean it can transmit an analog signal. I can't find that particular device.

    • @urzamaster
      @urzamaster  5 วันที่ผ่านมา

      Supposedly, it's pure analog, but it may just be a weak signal. I'll have to play with it some more.

    Put a real antenna on the CRT then select ANT instead of Cable in menu settings.
