System generator model

Hi, can anybody kindly suggest me from where i can get FM receiver (demodulator) models to implement on SFF SDR Development platform....please help Start a New Thread

Which platform are you after. Do you mean the one produced by Lyrtech? if so, they ship a number of demos with it. One of them is FRS demonstration which is basically an FM transceiver.

I understand that the Demo has a CTCSS encoding scheme so your problem is mainly the succesful removing of that encoding from the RX chain. Now I can provide you the following hints:

1- check a tutorial of building commercial FM receiver for GNU radio platform.
http://www.gnu.org/software/gnuradio/doc/exploring-gnuradio.html

Now I know it is different platform but hey it works and you must be able to get ALOT of hints from there.

2- can you hear anything at the receiver or it is a total noise? or you can hear some pattern or recognizable voice in the background?

3- which frequency or channel you are experimenting? remember that the provided antennas are centered at 400MHz!

4- Here is a tutoiral explains the FM example in more details:

I would suggest you to look at the tutorial of building FM receiver for GNU radio. While it is for a different platform but you can get alot of hints from there.

also check what frequency you need to operate at. the antennas shiped with Lyrtech kits are centered at 400MHz Start a New Thread

Hi,..i have separated the transmitter and receiver and implemented them on two different kits,...yes the antennas work from 400-450MHZ ,..but i have done communication at 262MHz through these antennas ans results were good,...now i wanted to ask that cani use the same receiver for fm reception too with the 88-108MHz antenna ,...like would i have to chage the filters etc
