This is a aircraft band receiver video. This video shows step by step how to modify the transistor radio so that the radio can receive the transmission radio from the air traffic control tower. Normally, to pick up the transmission radio from the air traffic control tower, the special radio or scanner. This video uses FM transistor radio. First the tuning capacitor must be found. After that, find the tuning transformer. Then, extend the FM range. adjust the tuning transformer to maximum. Here is the video:
