35MHZ FREQUENCY COUNTER

35MHZ FREQUENCY COUNTER

                                            Her the we are use main CPU PIC16F628A and 16x1 LCD  Display introducing 35MHz frequency measurement Counter. This frequency counter contains only a few components and easy to make SWL / Ham Operator.

MAIN FEATURES

·       Frequency measurement  35MHz

·       Sensitivity of less than 150 m.V

·       Operating Voltage 8V – 16V

·       Direct frequency measurement

·       2 select Gate time 1S <0.000000> 7Digit 125mS <0.00000> 6 Digit push a button 3S.

·       10 Hz frequency resolution.

·       9 offset channels selectable with a push button.

·       3 Offset channel  (VFO + IF) , (VFO IF), ( IF - VFO )

·       2 select USB/LSB displayed as N / R (Normal / Reverse) 2 Way switch.

Some E.g.1

•           3 Offset channel (VFO + IF), (VFO IF), (IF - VFO) / 9 offset channels

            VFO = 10MHz    / 9 offset channels 1 – 10.7MHz

            (VFO+IF) = F         10+10.7MHz=20.7MHz
