I’ve got 3 laptops and all are having the same issue. They usually have gizmos like that too. This pin adjusts the 19Khz pilot level.

It’s makes for great reading, though at times I have to wonder if it was even English. I think I may just leave datasheeet in the window. I don’t know datasehet it’s datqsheet signal problem or sound problem as it won’t stay clear long enough for me to tell. The rest of this is greek to me as well. 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.

Your latest post at Renaud is for an RDS encoder. One, it’s darn close to perfect for my needs already, and two, it’s something I can tweak with the rest of the setup done.

Then we can take a look at how Vast has this BH chip configured for both the 19Khz pilot level if at all and the time constant components in the audio section to see where they have the internal processor’s attack and release times set at. Hi Audio, I found the Stereo coder at the bottom It sure seems like that empty location where a SMD cap would fit would be wired up to pin Also, the chip is easily overloaded by high dynamic range signals, like a CD player. Many thanks to RFBurns for finding an answer to a problem with the FM02 and better still, supplying a fix for it.


I builted it from the same article.

Maybe it’s shorted and therefore not radiating properly? Analog Layout Finger Size 4. Again I am a firm believer in “If it’s not broke don’t fix it”. I may be able to help you, my show is going to be a little different this year where I will not be using my FM02, and I would be willing to sell it to you if you really can’t get yours working, I forgot what I paid dattasheet it but I would be willing to sell it to you for the same price i paid for it plus PayPal fees and shipping, if you are interested dataheet me adtasheet PM Oh Mac that would be awesome!

Perhaps all the problems won’t be resolved in a 3 week time frame before the big day.

The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. I’ve tried it with a PC power supply — horribly noisy.

Soldering the two pieces would fix this but so far, I’ve not done that yet.

Rohm BHFV FM transmitter

Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. Thanks again for the info!! I had a ton of 60hz buzz in my transmitter with anything plugged into it even a battery datqsheet MP3 player using the supplied antenna, the minute I hooked up my CB antenna all the buzzing went away and it sounds great again!

You could also try office supply stores such as Office Max or Office Depot. To bad I fried it or I would send it back. However if I unplug the 3.

If u have found it’s datasheet plz supply me the link Too high of levels of sub carrier and pilot carrier can also over work the final and cause it to prematurely fail. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.

Anyway, I would like to see the BH dataheet The BH was never really intended to be fed with audio going through an external audio processor. A mono audio signal can be from a microphone and most FM transmitter circuits have enough gain for a microphone.

The only thing that will happen to the FM02 is that its power output will be down from a I don’t have any testers here to see what the unloaded voltage reading is. Cause I’m really at a loss here.

It seems to work fine but I’m willing to play with it for grins. VCO Voltage Controlled Oscillator – An oscillator whose output frequency is controlled or changed by an application of external voltage.

SMD components, particularly resistors and capacitors can easily crack and open under light datasheeg. It must have an accurate crystal catasheet. I used a plain ol ceramic disc cap, clipped the leads so they would be short but long enough to allow folding of the capacitor on its side so it rests on the board. Uke – can you get the schematic for the FM01 as well? How do I physically connect a uF cap between pin 19 and ground? You need to be a member in order to leave a comment.

I just hooked it up and I can honestly say now that something was wrong with my original board.

If a crystal controlled transmitter may be used,then will it get better? These can be many. Though some think you shouldn’t use the 8V one, I sometimes take the “if it is working, leave it alone” strategy myself. Reading too much into my statement perhaps. Some people are trying the blame the antenna. Posted May 2, I had a similar issue and I found it was 2 different problems. I was unable to attach the crkt.
