Be careful, take your time, and GOOD LUCK TOOLS NEEDED: Philips head screwdriver Small standard screwdriver Wire cutters. The block diagram diagram of a simple phasetracking receiver is shown in. If you are not careful, you run the risk of having a problem that is very difficult to locate and fix. As mentioned, even integrated circuits available to phase lock signals. If you follow the instructions carefully you should be successful in building a receiver that works. The second nine volts battery powers the audio amp section and its good this way if you switch off the vlf receiver section the audio amp section appears to still be using some of the circuit. The INSPIRE VLF-3 receiver kit is NOT a simple electronic assembly.

Also the vlf receiver circuit takes a 9 volts battery and its input voltage is linked to the front sense head section so they can both share one 9 volts battery.
