Circuit Lake

This frequency counter can measure frequency with range 100Hz-2.5GHz. The project features including LCD 16 chara.x 2 lines and TCXO 12.8MHz(1ppm ). The project main part is PIC16F84. The Voltage(0-510mV) of the input signal is also indicated on the LCD , therefore tuning of the coil can be conducted while checking the frequency. Furnished with IF offset-function, this can be applied for the frequency display of the home brewed transceiver.
