prompt:
1. This is a set of machines, you need to weld yourself
Please confirm your technical level and equipment to avoid unsuccessful assembly and adjustment of the kit;
2. Because the VHF band is already similar to the propagation of light-linear propagation, the receiving location is free from the airport but the distance is longer (more than 25Km), please be sure to install a high-gain antenna such as the VHF section Yagi antenna; between the receiving location and the airport If there are large obstacles (including but not limited to tall buildings, mountains, huge towers), you must avoid the obstacles; otherwise, you can only receive the one-way signal from the aircraft on the way in, thank you!

Buying:
1. All kits in this shop need to be welded and debugged by the buyer;
2. The installation of the kit is risky. Buyers should correctly evaluate their technical level and equipment to avoid unsuccessful installation and adjustment of the kit;
3. The kit manual (electronic version) will be obtained from the shop owner after purchasing the kit;
4. The kit does not provide the circuit diagram of the pre-welded module, nor does it provide the source code or firmware of the single-chip microcomputer;
5. The kits are shipped with scattered electronic components. The pictures of the finished products displayed in this store are for reference only when purchasing;

Has the following characteristics:
1. Use PIC18F1320 single-chip microcomputer as the main control, built-in PLL local oscillator module (pre-welded, stamp hole plate, support calibration setting), with frequency indicator circuit (using 7-segment digital tube, display unit is 100KHz, the photo has color difference, actual Red), the receiving frequency covers 118-136MH z, 100KHz or 10KHz step (refer to the figure below, free switching).
2. The kit adopts a bandpass filter + high amplifier + NE602 mixing + TA7640 mid amplifier + LM386 low amplifier scheme, superheterodyne architecture AM receiver, single frequency conversion, intermediate frequency 10.7MHz.
3. With LED tuning indicator function, it can help to adjust the receiving frequency accurately and quickly, which is convenient for use.
4. This machine uses audio dedicated digital potentiometer (FM62429) to adjust the volume.
5. 12V power supply, the size of the PCB board is 84*120mm, which can be conveniently put into an 88*30*120mm aluminum case (the shop will order an R60 case in the future).
