audioguru Posted April 24, 2006 Report Share Posted April 24, 2006 hi Audioguru,Is this tv transmitter not going to give me a reasonable picture and what about sound. Dazza hasn't got any sound? why?....5.5MHz RF transformer ...Is this enough specification to buy it?Build it and try it. It doesn't have anywhere near the number of parts as a real TV transmitter. I don't think its picture and sound will be clear.The IF transformer must have a frequency to match what TVs use in your part of the world. Some transformers have tuning capacitors built-in, others need external capacitors. Quote Link to comment Share on other sites More sharing options...
