Airband Aviation Radio Receiver DIY Kit, High Sensitivity 118-136MHz AM Band, with AGC Circuit and Band - Pass Filter for Aircraft Tower Communication up to 190KM

Description:This DIY aviation radio receiver kit is dedicated to receiving calls between the aircraft and the tower. With high performance antenna (VHF antenna), calls between various types of aircraft and the tower within 190KM in open space can be received.Features:Adopt band-pass filter, 3355 high-level, NE602 mixer, MC1350 programs in place, can receive 118-136MHz AM signal. Printed directly on the PCB trace inductance, greatly simplifying the assembly. The board has to listen to the AGC circuit to ensure comfort, while avoiding the long squelch noise. 12 V power supply, PCB board size is 9.2 * 7.5cm, which can be placed in 97 * 40 * 120mm aluminum chassis to use.Specifications:Color: GreenMaterial: PCBBoard size: 9.2 * 7.5cmPackage weight: 73gNote:This is a DIY kit, hasn't been assembled yet!Due to the VHF bands have similar propagation - rectilinear propagation of light, but the receiving location accessible from the airport, distance(greater than 25Km's) must be installed VHF antenna contour segment gain antenna; receiving location between the airport large obstructions (including but not limited to tall buildings, mountains, towers) is always around the obstacle, thank you!Package List:1 x Airband Radio Receiver DIY Kit1 x Circuit Diagram
