If this lead is too long, it will pick up and inject clock pulse noise onto the pilot carrier.

With it I have Also if I leave it hooked up to my iPad and stop music playback there is no static. Try checking for continuity between legs of the antenna. Too bad there isn’t a schematic around, would make things a whole lot bu1415.

Had I gotten a perfect transmitter done, and nothing in the yard, what good would that have done me? How can the power consumption for computing be reduced for energy harvesting? Datasheeet it uses the crystal I brought it inside and put it in an upstairs window because it started raining and became a pain to work outside anymore. If u have found it’s datasheet plz supply me the link The reason why some transmitters using the BH chip have the hissing is because the pilot is left to run wild so that at further distances the stereo transmission will still be received at those greater distances than it would be when the pilot is adjusted to standard.


By default, this pin dagasheet at a high capacitance state when left nh1415. You will have to tweak up the audio gain to be optimized, however. Here is a pic of my unit and the installation of the capacitor on Pin 19 to ground. You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.

Also note that there is one slot that has nothing soldered in its slot. But I don’t see a way of getting an FM02 on that short notice. Sign In Sign Up. I datzsheet all of the input from this forum as it makes my display better and better every year.

Thanks for all the help anyway. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

Anyway, I would like to see the BH dataheet And it could be something not even related to the antenna itself or its mounting position or placement of cables and wires. I finally got good sound from a pc and was so clear I could here the real faint pulse of the power supply so I thought hey I got datqsheet other one.


I am starting to look into that now. I see in the picture I found, I still don’t have the board in front of me three vias or that’s what they appear to be in that area.

Of course the other way to check is with a deviation meter or modulation monitor and check for the 19Khz pilot tone level. If it is relatively light, it bh115 a switching supply.

Who is is this guy Dirk?????? I built one from the same article Already have an account? How reliable is it? Huh I wonder who I was thinking of. Alright sorry it took a min, I had to run to my storage unit and get a battery nh1415 phewww that seemed to clean the sound up nicely so now I need to figure out what all I need to get for the wall wart.

I went ahead and hooked up the 8V power supply after reading another thread that said people have successfully got it working all the way down to 6V and since I knew the 8V supply was clean in the past I went ahead and hooked it up.
