I am making a radio transmitter for underwater communication . The project will run on sea water and the device should run using a 32.768 kHz crystal ... I thought of using a Pierce (inductor-LESS) oscillator which looks likes this (photo) . The NOT gate used is a 74HC04 ,{ I also have a schmitt trigger inverter model : 74LS14 in case I need it . } . the capacitors are 18pF value Rf value = 1 MOhm R2 = 220Ohm ( I dont know if it's the right choice though ) .... The thing is that I dont know if it works as an oscillator... Can anyone test it for me with an oscilloscope ? Or send me a schematic made for LTspice ? Any general advices ? Many Thanks !
