DC 9-12V 1MHz-1.2GHz RF Frequency Counters Testers Digital PLJ-0802-E LCD0802 LCD For Radio 1-1200mhz DIY Kit

PLJ-0802 Embedded Smart Frequency Meter is a frequency measuring instrument specially designed for HAM. It is small and exquisite, easy to operate, and reliable in work. It is mainly used for DIY transceivers for frequency value display, and can also be used for routine frequency measurement. The main features of this frequency counter are as follows: ⊙ A high-performance 1.2GHz frequency meter based on Microchip's 8-bit microcontroller PIC16F648A. ⊙ Built-in frequency reference adopts temperature-compensated voltage-controlled crystal oscillator (±2.5 ppm VC-TCXO). ⊙ Double intermediate frequency design, intermediate frequency value and plus/minus mode can be preset separately. ⊙ LCD0802 LCD screen display can display 7 digits, and the frequency value is invalid and zero is automatically blanked. ⊙ Anti-reverse connection design, low-power battery-powered solution. ⊙ Double button control, good man-machine interface. ⊙ All settings are automatically saved in EEPROM, and they can be called directly next time the machine is turned on.
