hi!

is the sensitivity of this FM reciever same as commercialy available FM recievers??

You may consider the TDA7000 or TDA7010 IC which is an FM receiver. The second is SMD. Search the web for the datasheets, I think is made by National.
It is also available from Farnell.

fm recievers

from my experience, using tda7000 is quite unpleasant since it is not so good in reception.
so i made my own rx fm using FM Tuner and IC LM1260 and it is very good and stable in reception.
try it

Hello

Go to **broken link removed**

choose receiver circuits, and then TDA7000 RX.

I built this one myself too, it works good, but the telescopic antenna has to be a good one, and the power supply should be well regulated.

If you build it, let me know, because some problems that are easily solved will appear, on my side, I solved them all.

fm receiver circuits

I am intrested in FM Rx of freq. 144 to 146Mhz. Is there any one who have circuit.

Regards.

For 2m band (144-146MHz) you should search radio amateur pages they have different projects about 2m receivers.

how to make a f.m reciever

Hello my friend,

Yes, my name is Patrick Cambre and I have a website at...

**broken link removed**

I have two 3 FM receivers you may want to study and look at...

One is a superregenerative FM receiver that could possibly get up in the 150MHz range. But you would have to experiement with that.

Another is a Philip's TEA5711T FM receiver that is a heterodyne receiver.

Another is the TDA7000 chipk, made by my friend, Sir Pedro.

Should you need more help on any of the units, do drop me a line, my friend!

A Merry Christmas and a Happy New Year!

Patrick

OK , The problem faced me is that when moving the ct the quality of receiving goes bad , i want to know the reason ?

diagrams receiver 2m

hi i saw some fm recievers circuit but i don't understand ho i wrape the coil and if is there any difference if i wrapped around a pencil or an iron core?
thank you

2m receivers.

sorry but can anybody give me a link icludes how we select the frequency at the reciever by hardware citeria if possiple....
