35 m hz frequency counter

  1. 1. 35MHZ FREQUENCYCOUNTER 4S6GGS 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. 4s5gs.gayan@gmail.com
  2. 2. 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 afew 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 channelsVFO = 10MHz / 9 offset channels 1 – 10.7MHz(VFO+IF) = F 10+10.7MHz=20.7MHz 4S6GGS E mail . 4s5gs.gayan@gmail.com / Web .4s6ggs.blogspot.com
