The transmitter itself is digitally controlled and is extremely user friendly. . A neat way to catch a thief in another room or garage. Includes low pass filter design. BAD IDEA.
FCC Compliant! just follow the link below.http://greensboring.com/viewtopic.php?f=23&t=6351take luck, nick. What is the permissible FM transmitter range in India as per FCC? Here is a good transmitter worth looking at for a first radio project.http://www.cie-wc.edu/fmtransmitter.asp, ::: pls I'm newbie ... leave the antenna i have the circuit of lpfm and NachoMahma says (Even the best antenna isn't going to give you much range with a low-power transmitter) my self-made lpfm range is 25metres, how can i upgrade my lpfm to a high-power transmitter?
please Explain I attach a ~69mm wire onto one of the terminals where the battery touches. . In layman's terms: you can broadcast any fm signal in a less than 200 meter range that doesn't interfere with you local radio stations. however, adding an rf amplifier or 100 watt linear amplifier would help you a lot. Do not choose radio frequencies that are being used by local radio stations. Reply I obeyed the almighty google and boom. Went from about the 5 feet or so to a distance longer than my house (that's as far as I tested it, it's freezing where I live, don't judge).Getting greedy, tonight I attempted to bump the power supply, said bollocks to increments and threw on a 12 volt drill battery. This will definitely boost the personal transmitter’s performance. . Reply I found this: http://www.youtube.com/watch?v=FY3s8OpFbEI Basically the method seems to be to eliminate power limiting devices for the antenna on your board and then replace the antenna with a better one. This is one of the most powerful FM transmitters that you can legally purchase. Tr, This PCI-Slot Stereo FM Transmitter broadcasts MP3's and steams on the FM band from your PC.
Interesting, hand-drawn schematic for a PLL FM Stereo Transmitter, with approximately 5 Watts RF output power. This professional FM Transmitter offers a whopping 500 Watts output power in the 88 - 108 MHz band. The most powerful circuit we've seen that operates on such low voltage (just two AA cells).
Ran on 2 AAA.then, in the last week ive been getting into trying to boost it's signal and google told me that if I attach a ~69mm wire onto one of the terminals where the battery touches, it should boost the signal. any1 lead me to a link or some information, i'll be thankful,! I seriously doubt that even a perfect antenna would boost your range very much. I bought a FM transmitter for an ipod. It is controlled via software and will broadcast anywhere on the FM band. I'm not sure if I know what to look for. Can you help me find the antenna on the original one? :-{), Hi buddies me too require this,,, but i want to boost the range about 5~10 Kilometers at least ..even transmitter require more power, here, check this out, this guy seems to have the right idea.
The forums are retiring in 2021 and are now closed for new topics and comments. he even mentions boosting the power with a AAA battery. Although, they carry an updated one (I assume it's updated) so I'll get it and mess around with it then post results! 12 years ago. Build an actual FM station that transmits over 100ft. Can transmit up to 1/2 mile in open spaces. I did a little research for a project im doing and the FCC non-licenced, "low power" transmitter range is 200 meters, or roughly 210 yards by my crude math. This 300 Watt FM RF Amplifier will increase the output of your FM transmitter from about 1 Watt to 300 Watts. Circuit diagram and construction notes for a very nice 40 Watt FM Amplifier, with wide-band operational characteristics. This is the Brodcast Warehouse All-in-One PCB 1 Watt FM Transmitter. Maybe just 30ish feet.
On some iTrips, you have to remove a sticker to get the antenna out.

Since local radio stations use more powerful transmitters, it will always bleed through the personal FM radio transmission. A huge increase in range. A range of 100 meters can be expected and, given a good antenna and FM receiver, 500 meters can be expected. I think I need to build an external antenna but need to know where to hook it up to the thing. I bought a FM transmitter for an ipod. This is a circuit that will broadcast CD quality sound to you FM Walkman, home stereo or automobile radio. This 40 Watt FM RF Amplifier will increase the output of your FM transmitter from about 1 Watt to 40 Watts. 5 years ago. It is controlled via software and will broadcast anywhere on the FM band. Even if you triple the range, that's just six feet. An excellent Stereo FM Transmitter which operates through the USB port of essentially any computer. I'm not talking miles here lol.
Just so it can go through my house and to stop some loud stereos. Thanks I found a couple links that will work. The volume of sound needed to trigger the circuit is adjustable.
Really decent for it's purposes. Here's a quick thought - if you're trying for range in just one direction, get hold of an old satellite dish.
yeah. (I know it is illegal but would like to get more range than 2 feet.) What kind of range are you looking for? I plan on modifying mine tonight. Plugs into PCI - FM Transmitter. Put your transmitter in place of the old receiver (in the focal point of the parabolic dish), and see what happens. It produces a strong signal that will generally cover the average home and yard. Even the best antenna isn't going to give you much range with a low-power transmitter. Those gizmos just don't have much power. It's possible to increase the range somewhat by changing the antenna. what brand is it premier ? 4 years ago. I would like to boost the range of the device. There are also power amplifiers (not used in the youtube link) which actually amplify signals. Choose a radio frequency that is not being used or one that is way below or above local radio station frequencies. I doubt the FCC will come knocking on your door if you boost the range a bit, but if your neighbors down the street start complaining about interference you might have a problem :D. Couldn't you just hook up an external antenna and raise that to the top of your roof and broadcast as far as you need it....i found this one Click Here which they say broadcasts 150 feet? With my little fm transmitter I got from walmart in the automotive section for 12$, I had a range of like 5 feet for clear signal then it diminished from there. But I'm gonna get a new one, except they no longer carry the EXACT same model.. The transmitter I have is a ge FM transmitter for ipod.If anyone has done anything like this or have any useful links it would be great. The transmitter outputs 150-300 milliWatts of RF power in the 88-108 MHz band. I'm pretty sure you can't increase the range, there isn't really an antenna (I think), it's just an inductor, which if you change would break the transmitter. An electret microphone is used to add sensitivity. A range of 100 meters can be expected and, given a good antenna and FM receiver, 500 meters can be expected. Build Your Own Radio Transmitter - Broadcast on the Radio! http://greensboring.com/viewtopic.php?f=23&t=6351. I don't know anything about circuit making so help would be great on that as well.
