Dear All, I am thinking of making a AM/FM radio using TEA5710. I was looking for a TEA5767 breakout board but was unable to locate one and found TEA5710 DIP IC instead. I have no prior experience in designing a radio and have never done so. Can anyone please explain me the values and components mentioned in the datasheet? [url=obra
I'm not sure how to approach this but I am suppose to create a receiver capable of receiving the AM signals from the radio station WWV in fort Collins,CO on the frequencies of 10Mhz.
Hi, does anyone know of a low power IC that can TX RX between 470mhz - 850mhz ? I am trying to make a radio mic transmitter and receiver design that can be configured with a micro controller to transmit / receive at around 25mw - 120mw anywhere in these frequencies. I am interested in both using both WBFM and GFSK if I
parts i have : antenna wire,magnetic wire,toroid core, 23 mhz crysrtal oscillator,some transistors ,resistors,capacitors.... i want to design circuit to simply on and off the led by radio waves. could u sugest me simple circuit with to do this.. plzz.thank you in adavance
I have the above mentioned mobile phone. I want to use it as FM radio reciever only. But for the radio to function, I must connect Headphones. So I have to make an 'adapter' between the 3.5mm Jack of my headphones and the USB Micro-B of the phone. (headphones can be attached to USB only). USB Micro-B has 5
A kind of radio receiver that is able to handle a very wide frequency range is HP8592 spectrum analyzer. It can handle from 9kHz to 22 GHz and with extender even wider. It's purpose is to measure signal strength. Not intended for listening, even if it is possible with some additional equipment. If you want to be able to receive a lot of radio-stati
Dear forum members, I am new to the forum and what is worse, the last time I saw physics was at the 8th grade.. I work for a research agency and we would like to measure a distance (ranging from 2-300 meters) of a reciever from three distinct points (at best several recievers and 3 stable beacons simultaneously) and collect the data to a comp
Hi I have a need to interface a Millimeter wave radar antenna with an MCU for an automotive application. I lack clarity on interfacing the antenna to an MCU. I know a way of interfacing them using radio transmitter and receiver. I'll be happy if I get other ways, if any. Thanks.
I guess, you can find SDR (software defined radio) kits that cover the GPS frequency range.
The feed should be made with a delay section of the feed line. Consult e.g. the ARRL radio Amateur's Handbook or ARRL Antenna Handbook for details. In principle the delay section is a quarter-wave long feed line. As coaxial cables have a dielectric inside, you should use the "shortening" factor available from cable specifications.
The following is FM radio reciever circuit from: I do not intend to implement, but Surprised by the way the two transistors T1&T2 connected. The tuned recieved FM signal inter the col
Hey guys... I was hoping u guys would help me out... I built the simple fm transmitter from the circuit from talking electronics Code Puzzle and it works fine... Now, I got super interested in radio technology after this and now I want to make a 50 Mhz radio receiver... Th

Why not use tv tuner fed to 10.7 MHz if stage with a mixer stage having 35 MHz osc. I once made 45-850MHz reciever using tv tuner and fm radio reciever with local osc frequency modified. tv tuner if output frequency is around 46MHz.
We used radio antenna, which are very cheap and we can adjust the height of the antenna to our wish..... I got a very good and considerable length coverage with that too.......
hello, i have recently started to fly radio controled helicopters and have discovered that it can be quite difficult to place the reciever's antenna. there are a lot of metal parts that can shield the signal from certain angles so i was wondering if it would be possible to use the tail boom which is typically anodised aluminuim as the antenna.
I am building a bespoke radio controlled model... it used a 3 phase ducted fan ac motor and to control this it has an electronic speed control which is sent control via the reciever. I know that the reciever gives square waves to the esc and then the esc proportionaly sends the correct voltage to the motor. I want to replace the (...)
My car radio does this perfectly, based on the RDS station info. It has a dual tuner to scan the available stations and check their field strength, also used to receive travel pilot information independently of the currently selected program. As far as I understand, it's a standard feature of
Hello there.. i have one question and need some opinion/suggestion from others about my project.. my project is about RF.. What I'm try to do is, I need to design a FM receiver that can tune the channel radio by itself using electricfield.. For example, I'm from location A and I want to drive to location B. At location A, I listen from the radi
Look in the datasheet of the TDA7021, this is a complete FM receiver.
I need orcad model for 10.7MHz ceramic filter to simulate 3stage IF amplifier in a radio reciever.
In general, you can't. You CAN buy a single dual polarized antenna and hook that up. You can hook two antennas up to a single radio, but they have to be RF isolated, like on opposite sides of a building. You would use something called a "power combiner" or "power splitter".
i want to make an AM radio radio reciever can any body help me
I don't know if this post is in the right forum spot, meh.I will trying this out tommorow to find its range but im guessing 3 to 9 feet and by the way if you add a headphone jack to the transmitter (also available from radio shack) you can hook it up to a CD player,TV,computer,stereo etc... It should be fine for that range for a wireless compute
hello seadolphine2000, im much more into the DIY radio link ..... any other? been googling for hours, never seen ANY, at least not for the readymade radio links...
hi nford, you can check tea5768 and tea5764 from nxp /philips/ best regards, stroma
use a close coupled radio reciever must recieve usb to the clock freq of the chip if its a pic16 then its 4/xtal clock then you need also to disable any automatic gain devices and turn it on youll hear the program load as a grrrrriiiiiip this sound can be filtered back to a digital train and this is infact the eeprom in
Hello people, I hav constructed one DTMF based Fm transmitter circuits successfully.. Now for de-coding it i need a Fm reciever.. I tested my transmitter with a commercial radio.. Its working pretty well at around 99 MHz.. I want to construct a reciever circuit myself.. So if u hav good working circuit or any link to a good Fm (...)
Google. Here is a page of CB radio circuits These and some others use MC3357 FM demodulator
Has anyone built a reciever with LA1805 of Sanyo? It's an old chip, BUT with VERY good reception (I have bought a reciever with excelent reception, it's using this chip). I know the datashett has a schematic and PCB but it has mistakes and I want something simpler, like the one found in the radio I bought. Does anyone have any idea?
serch in google "crystal radio" you fine many link
why we are using FM for radio broadcasting..why not PM fo the same.....i am really confused.....
>have no idea and need some references Read some amateur radio books. You have not told us what frequencys you want to receive. SSB is mostly used on HF, 1.6MHz-30MHz. If you want to receive on a single frequncy or a narrow band such as 40 meter amateur band 7.0-7.1MHz you can design a filter for that band. A single LC circuit may be enou
just a thought, use a radio as a receiver. u get a wide range of frequency. right? that is what ppl are doing for projects like yours.
What would be a good RC circuit that controls two servos (transmitter and reciever)? For starters I need something that can broadcast at least 200 feet, is easy to understand, realitively easy to build, and is stable. What I am doing is building a remote control that transmitts on/off signals from the computer's parallel port, and the reciever en
It's POSSIBLE! Perhaps you heard about Software Defined radio, or SDR, which suggests that use digital devices in radio facilities as much as possible. But you still have to design some analog parts: RF front-end, and baseband signal amplifer. 1) RF front-end, an high-speed ADC is used to sample and quantize the analog signal received from antenn
Please help me on this project. SPECIFICATION: 1)I want to control a AM reciever circuit with computer so that I recieve local radio transmission and listen the recieving signals on computer's sound card. 2)I want to tune channels by computer.
