This is 7-digit frequency meter measuring frequency from 10 Hz up to 1300 MHz. It is based on ideas of PIC16F84 based frequency meter. The measuring range is divided into two subranges: 10Hz - 25MHz and 25 MHz - 1300MHz. The decimal point is after MHz digit, but can be set at any position. It contains: * PIC 16F84 * 74HC137 (BCD -> 1 of 8 decoder) * SAB6456 VHF-UHF divider by 256 * 7-digit calculator display (common cathode), * some resistors, capacitors and 2 switching diodes
