Oписание продавца
Features: 1.Purpose: It is specially designed for receiving calls between aircraft and tower. With the good performance antenna (Yagi antenna in VHF section), it can receive calls between various types of aircraft and tower within about 150Km in the open area. 2.Features: Use PIC18F1320 microcontroller as the main control, built-in PLL local oscillator module (pre-welded, stamp hole small plate, support calibration setting), with frequency indication circuitry (use 7 digital tube, display unit is 100KHz, the photo has color difference, actually is red), receiving frequency coverage 118-136MHz, 100 kHz or 10 kHz step. 3.High Sensitivity: Band-pass filter, high amplifier, NE602, MC3361, TA7640, LM386 to complete the secondary frequency conversion, one IF 10.7MHz, two IF 455KHz, ultra-high sensitivity, can receive 118-136MHz AM signal. 4.With LED Tuning Indicator: help to accurately and quickly adjust to the receiving frequency, convenient to use. 5.Squelch: Free setting threshold, to ensure the comfort of listening, to avoid long time noise. At the same time use audio special digital potentiometer (FM62429) to adjust the noise threshold and volume. 6.Ceramic Filter: Ceramic filters are used in the first and second intermediate frequency circuitry, which greatly reduces the difficulty of amateur measurement. 7.Size: 12V power supply, the size of the PCB board is 8.4x12cm, which can be conveniently put into the aluminum case of 88x30x120mm. 8.Tip: Because the VHF band has been similar to the propagation of light ---- linear propagation, the receiving site is accessible to the airport but the distance is far (greater than 25Km), please be sure to install the VHF segment Yagi antenna and other high-gain antennas; If there are large obstacles between the receiving site and the airport (including but not limited to tall buildings, mountains and giant towers), be sure to avoid the obstacles; Otherwise, it can only receive one-way signals on the way to the approach of the aircraft Specifications: Type: Spare Parts, Finished Material: PCB Color: As Picture Size(L*W): About 12x8.4cm/4.72x3.31inch Package Included: 1pc x Receiver Kit Payment must be received within 7 business days of auction closing.
