I had to put my equaliser’s bass buttons up a bit. The FM modulator can be operated from 76 to MHz and power supply for the circuit can be anything between 1. Definitely NOT the chip to base your 5 W transmitter to broadcast around the town. B Channel separation is not so good.

However, what I liked best about the BA was the amount of excitement it created among the hobbyists. These harmonics would fall into the higher part of the MPX signal, deceiving the receiver into feeling that there was extraneous content in the original Audio channels.

C13 and C14 are just coupling capacitors, nothing to do with pre-emphasis. The kit pre-emphasizes the Audio inputs passively.

Left in and right in are audio inputs, of course. Your email address will not be published. Please give me the address.

What is left in and right in. It is a joy to assemble the kit. To make matters worse, the music would modulate the high frequency daatasheet.

No use post-morteming the BA as it’s gone, but datwsheet the kit manufacturers will do their NJM kits properly. Add them up passively, just making sure they are in phase More complete method: That’s not as easy as it seems, you can write a book on Audio filters.

Suppose you have a 10 KHz Audio signal and it is clipped a bit, it will generate harmonics. Not noticeable when you play rock, but when I played the Bass drum track, after each drum beat, the high frequency note would ring and then stabilise a second later.

When you slightly overdrive a Mono signal, you get a slightly distorted output.


Can you send me. Sound quality did improve a bit by reducing Modulation levels. The sound quality is good enough if you like loud Rock and Roll and are going to receive it on your small radio out on the porch while the kit’s connected to your CD player indoors. When you overdrive an MPX circuit, you are in for trouble big time. I lost the “Stereo” and the “Tune” lamps on my receiver which began outputting odd sounds and beats.

Still the chip was fantastic in that it allowed you to transmit some kind of Stereo at the real low end. Stereo FM transmitter circuit. Can it dstasheet possible to make a radio mp3 broadcast a long distance without buying an external boaster?

The FM Stereo rules say that the Pilot should be a sine wave, not square as square wave would have harmonics. I connected the kit to my Kenwood CD and tuned it to I was expecting a low level of signal to ooze through to the other channel, but not so distorted!!

Maybe that’s the reason for the deficiencies noted above?
