Help me build FM receiver with sharp frequency adjustments

tda7010 schematic

Considering the winding core (air or iron ) ,the core of the coils changes its inductance so much , so you have to do the coil with the core mentioned in the circuit, the no. of turns is also so important but the spacing is not as you can change it later using wooden or isolating material during the operation of the circuit, to tune/fine tune the circuit , wishing this might help

Or you could use a good equivalent for the MPF102. See below.

Industry Number : MPF102
NTE Device Number: NTE451
JFET-N-CHAN, UHF/VHF AMP,TO-92

the fm receiver circuit must hv pll tuning circuit for stability. Select any ic as suggested above that hv good sensitivity.

circuit fm receiver

Hi,
I am looking for a solution for receiving 156MHz to 158MHz. The IF should be as usual, 10.4MHz upper than this... I can make a tuned RF Fed for the entire band. Then i can make a Oscillator to oscillate at 10.7MHz heigher... but I need a tuning using a pot and thus i can have one front panel pot for tuning the varactor. So i need a good ckt diagram for this... can any body help?? i cant figure out the exact mixer also... plz help me...

circuit fm receiver analog

hi guys,

i need your advice here..

i am currently using TDA7010T . the problem is in its datasheet, there is no description on the value of each component in constructing the FM receiver. ( ie capacitor, resistor etc )

any one can help me?

i try to use TDA 7000 as i already found a lot of reference about it but currently it is out of stock.
and what is actually the different between TDA 7000 and 7010 ? what changes do i need to do on the circuit between those too.

thank you in advance.

Hi,
The difference is that TDA7010 is surface mounted, while TDA7000 is not.
See the components in the datasheet fig 4, 5 and 6.

// Regards

thnx wyatt..

does anyone know how can i design pcb track using software?
currently i try to explore pcb123 program. but i can not find tda7010t in the component library list.

or is there any source that can help me?

Hi,
I'm not familar with PCB123, but since TDA7010 is not so common, you should use a similar component (equal number of pins, etc.. Search the lib!).

/Regards

fm reciever

hi guys

i hav to make a fm receiver
the ckts i hav found either consists of TDA 7000 or TAA 300.
and both of them are out of stock.
so pls help me out with a link or ckt of a simple ckt.

If you are making layout only you can select the SOIC or SSOP package( as defined in the datasheet)
If you want to make schematic and then work it conventionally, perhaps you have to create the component.

For that the best is to read the user manual. Mean time I shall also try whether i could do one for you.

Kushal, please try any of the CXA series of SONY
for example CXA1019 is generally available in market. There are mini kits using DIP ICs for FM receiver. purchase one as they are very cheap. you can salvage a very part and have a new layout to fulfill your hunger. Generally It is preferable to purchase one Like Kchiboo etc at DAM cheap price. Regarding Project, you make another RF project.

fm recievers

Most of those old ICs are not made anymore.
That is why they are out of stock.

I got some "FM radios" with the TDA7088 IC for free. They are sold for $1.00 at The Dollar Store complete with battery, headphones and a light.

The reception is terrible. Sometimes they pickup a strong local station but usually it fades away.
The sound quality is awful.
You get what you pay for.

I made FM reciver like cambre but with BF 256 and work well.
I also made several FM superregens with ordinary BF types and work .
When i'm find shematics i will send you...

simple fm receiver project

the circuit doesn't have to be pll. it's enough to have AFC for stability.

build fm receiver

Cheap radios have AFC so they can follow the horrible frequency drifting from radio stations. Hee, hee.
