MarkT thanks for your response. I have a pair of 25khz receiver/trancemiter and the problem is my knowledge in electronic engineering is none. i have found some diagrams for ultrasound receivers but i don't know if they will do the job
here are some of them :

florinc i am trying to create an underwater texter, so logging the message won't do the trick.  XD
thanks any way. I am already over that 2 weeks now and my mind is a mess right now, you never know when a fresh idea is going to come.

Thanks
Athanasios
