I am using USRP1 and RFX400 daughter boards for this.
I have made some changes in the flow graph as per discussed.
When i use quad rate divisible by audio rate , i don't have a good 
demodulation, and also experiences underdamped errors,
and when i use exactly as audio rate. i have good demodulaion and also 
experience overdamped.

I also want to use squelch so that i don't hear noise when push to talk 
button is not pressed, but this is not working? if u have suggestions 
then it would be helpful to me.
