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

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.
http://www.linuxjournal.com/article/7505

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

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
