Apparently Windows is being used, so bring up the Mixer in Windows by double clicking on the speaker icon in the tray. If you need one, my neighborhood sounds like a bu1415, so there is a good supply.

Where was ground available? There should be a buffer stage before that final so that any impedance changes taking place at the antenna will not affect the loading of the RF output pin on the FM chip because loading effects can also affect bbh1415 that FM chip performs and sounds.

Losses in inductor of a boost converter 8. I run one that works mostly perfectly, and from being on these forums for a little over a year, bh1451 seems like they are very popular here. I am also confused about Rohm’s new FM stereo transmitter ICs because their datasheets don’t have any details.

Then amplifiers are used to send an appropriate voltage back to the VCO to keep the desired frequency stable. The FM02 is pretty sensitive to that.


If necessary you can run a short wire for the ground connection to the pf capacitor. PM me if you want to do this and I’ll send you my snail mail address.

Finally determined it was the router and most specifically the enet cable from that to the show PC. If your using an external audio processor you might have to adjust it so that it does datashet fight with the IC’s internal processor or the internal IC processor fighting the external one. I have incorporated this very good information into the FM02 wiki!

Some models are exactly like this, while others may have a foil trace leading away to la la land and goes no where or connects to anything else. It has now, and always has had a very loud buzz.

Ask and you shall receive. I started this topic without any knowledge about transmitters Hh1415 one daasheet of the cap to Pin 19 at it’s very end to avoid over-heating the pin. I still haven’t been in the same room as mine so can’t check for myself. VCO uses varicap diode that changes the capacitance as different levels of voltage are applied. If there is interest, I can send whoever wants a couple of these capacitors for 10 cents.

A mono audio signal can be from a microphone and most FM transmitter circuits have enough gain for a microphone. Have we lost our perspective? One end of the datashete capacitor is soldered to a nearby ground point and the other lead directly to Pin 19 on the FM chip.

All wires re-routed, router moved 5 feet away, and I have no more hum, buzz or hiss. I may just purchase one of these FM02 units and perform a little product review of my own I builted it from the same article.

Is this due to One, it’s darn close to perfect for my needs already, and two, it’s something I can tweak with daatsheet rest of the setup done. The problem is with the lack of adjustment of the pilot level itself and that is done at Pin 19 of the BH chip.

And what about renaud stereocoder The stereo encoder circuit that you posted from Telkomsa has an inaccurate oscillator, is missing pre-emphasis treble boost for both inputs and very sharp lowpass filters. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.

PM went through, will talk at you b1h415 or when ever you are online, have a Happy Thanksgiving Mac: I went ahead and switched it over to the 12v power supply as well with no change in sound quality. Pin 19 is the 19Khz pilot tone level. I would guess from datasjeet current rating, the supply is a switching type.
