LM317T Voltage Regulator with Pass Transistor

Phase 1 of G3020 Software Defined Radio. This small clip shows the +5V power supply in action after completing phase 1, not a very exciting phase of the build but a very important one, unless this stage is working properly non of the IC's on the board will get there proper +5 volts they need. The circuit uses the popular 7805 5 volt regulator to take 12+ volts down to around +5 volts for the IC's. When this phase is working correctly the green led should light and the voltage jk1 jumper test point should be around +5V
