Frequency Counter Construction Tips

The frequency counter construction requires some careful home brewing.The following points should be taken into consideration which will help you in constructing it and incorporating in your commercial or home brew TCVR,Receiver or Transmitter.

1. A soldering Iron with a pointed bit should be used as the tracks on PCB are
   quite narrow.
2. First Mount all the common cathode FND,solder them to the board,after that
   check the FND with a multimeter each point of FND,which should glow.Now this step insures that all your FND are working and properly installed on the PCB.
3. Now mount the 7805,IN4148 and 220 ufd capacitor.After soldering it on the board,now connect 12Volts DC Supply and check if the 5 volt is being generated by your regulator stage.If its giving 5 Volts,then your second stage is completed.
4. Now connect all the remaining components,leaving the Pic,which should be connected at the last step.
5. After all components are mounted and soldered its time to mount the Pic base and solder it on the board,finally insert the Pic into its base,but do check the correct polarity of Pic.
6. Check if all your jumpers are connected.
7. Now Apply 12 volts again.The counter will start with all the FND illuminating,but will settle to one digit lighting to zero. This is the safe power mode.
8. You can programe the Pic by going through the manual of the frequency counter.
9. The small switch is used to programe the counter.
10. After programming it connect the VFO of your rig with a suitable resistance,now you will get the frequency output.
