      Simple Phone Tap

      This circuit is extremely simple, therefore there is less chance of any problems. It can be placed anywhere on the phone line and it will record any conversation on any phone on that line.


      This the Schematic of the Simple Phone Tap


      Total Qty.
      R11470 Ohm 1/4 Watt Resistor
      R211K 1/4 Watt Resistor
      R31100K 1/4 Watt Resistor
      R416K 1/4 Watt Resistor
      C1, C220.01 uF 100V Ceramic Capacitor
      K1124VDC Reed Relay
      MISC1Wire, Headphone Plugs, Phone Plug Or Alligator Clips


      1. To use the circuit, simply connect it in series to the phone. Then plug in the recorder. It will start recording when the phone is picked up.

      2. The values of R1 and R2 may have to be adjusted, depending on the characteristics of the phone line it is connected to (they vary). If the R1+R2 combination is increased sufficiently (try 2.47K) then the circuit can be connected in parallel with the line, thus covering all attached devices.
