This is right up your ally Eric, did you not design oceanographic equipment for the company you had?
Trungkstn; Eric is not gonna just hand you a design, I expect he would want you to put forth some effort on your own. When you get stuck on your own design, then you can expect some help, but do not just ask for a ready made project.
I'm only a student. I try to complete my project for a subject. hic hic.
i have some idea for design. I'll post soon . I don't want to receive complete schematic. I want to do by myself. But I confuse about designing transmitter because I'm not sure about required voltage level. I intend to use push-pull.
This is a circuit for ilustration purposes its 200Khz but same principals for 50Khz. T103 gives a wave form of about 330V 200Khz pulses across the transducer. The transformers are designed for the particular freq you want to use.

Thank 'debe' a lot. I'm an amateur. hi hi
And i also thank for your guide, especially Eric. Thank you so much.
I'll read carefully your recommends and if i have question i'll ask you again and i hope i'll receive your assist.
More just for your interest it a Furuno FE300 sounder that uses a National ic LM1812 that eric posted. I still have a new LM1812 as i used to repair sounders. So in the design area Eric might be the man to ask questions
Dear Debe,
Would you please send the JPG file again.I think it does not work.
I want to work on echo sounders too and I think that would be really helpful for me.
Thank you in advanced.
regards
