There is enough place to work around easily. If one uses a monolithic IC to do all the work, one is limited in the amount of genius one can display using that chip. Is a ready-coil available in market? In the circuit R7, C16, C14 and R6, C15, C13 forms datashret pre-emphasis network for the right and left channels respectively.

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.

I have a problem with this coil.

BA,ROHM – Keysemi

But horrors, I put in only one channel of Audio and ground the other channel’s input. Can you send me. The kit pre-emphasizes the Audio inputs passively.


What is left in and right in. C13 and C14 are just coupling capacitors, nothing to do with pre-emphasis.

As expected the kit went berserk at the high end. When you slightly overdrive a Mono signal, you get a slightly distorted output. The PCB is very good quality and so are the components.

Add them up passively, just making sure they are in datasheft More complete method: For that I would like two copies of 38 kHz quartz please. Tuning was easy, The signal moved around by only 25 KHz initially till Thermal equilibrium was reached. One is forced to do everything the way Datadheet dictates.

Or could it have been simple clipping? Composite stereo signal is created by the stereo modulator circuit using the 38kHz quartz controlled frequency. Hi Nin you can use series LC tuned circuit between Pins 5 and 6.

Previous post Next post. Professional gear would have a “brick wall” filter to remove all content above 15 KHz before feeding it to the MPX. The FM modulator can be operated from 76 to MHz and power supply for the circuit can be anything between 1.

That’s not going to sound pleasant at all!! The steeper the filter, the harder it gets to design dattasheet without other problems showing up.


Cana Kit CK ( BA based Stereo FM Transmitter)

Maybe the BA was a decent enough little chip anyway, but nobody used it properly? No use post-morteming the BA as it’s gone, but hopefully the kit manufacturers will do their NJM kits properly. Cana Kit claim mtr range in the open.

The kit took me about an hour to make. The BA is gone, long live the BA!! It was very slight catasheet it was always there. I tried different antenna and found that could shift the operating frequency by KHz. I lost the “Stereo” and the “Tune” lamps on my receiver which began outputting odd sounds and beats.

I had to put my equaliser’s bass buttons up a bit. C I ran a 20HzKHz sine wave sweep signal through.

Please give me the address. Radio Transmitters Previous post Next post You may also like: Definitely NOT the chip to base your 5 W transmitter to broadcast around the town. When you overdrive an MPX circuit, you are in for trouble big time.
