Product Description:
1. The SMD components on the main control board have been pre-welded and connected to the bottom board in the form of a stamp hole. The single-chip microcomputer uses PIC16F1938, built-in PLL local oscillator, supports crystal oscillator calibration setting, and comes with a frequency indicating circuit (using 7-segment digital tube, display unit is 100KHz , The picture has color difference, the actual color is red), the receiving frequency covers the 88-108MHz FM mode of FM broadcasting, and the aviation band 118-136MHz AM mode, 100KHz or 10KHz stepping (refer to the picture below, free to switch).
2. The kit uses bandpass filter + TA2003 + TA2003 + FM62429 + LM386 to complete frequency conversion (FM is primary frequency conversion, AM is secondary frequency conversion), one intermediate frequency 10.7MHz, two intermediate frequency 455KHz, ultra-high sensitivity, and cancel the mid-cycle and can Adjust the inductance, no need to debug after the whole machine is welded.
3. Added "Flying Shuttle" function. During 100KHz step adjustment, if the step is greater than 15*100KHz within 3 seconds, it can automatically enter 1MHz step mode, and automatically exit after stopping tuning for 5 seconds to assist in accurate and fast adjustment To the receiving frequency.
4. It has a squelch circuit and freely set thresholds to ensure listening comfort and avoid long-term noise. At the same time, use the audio dedicated digital potentiometer (FM62429) to adjust the squelch threshold and volume.
5. The first and second intermediate frequency circuits all use ceramic filters, which greatly reduces the difficulty of amateur commissioning.
6. 12V power supply, the size of the PCB board is 8.4*12cm, which can be conveniently placed in an 88*30*120mm aluminum case.
Reminder: 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
