This page provides some tools (software by myself), hardware, and other information for radio amateurs, and some other not-radio-related stuff like the PIC programmer.
DL4YHF - Ham Radio and Homebrew
This document describes the construction of small frequency counter with a cheap PIC microcontroller and a few seven-segment LED digits. The main features of the frequency counter are: frequency range 1 Hz ... 50 MHz (prototype worked up to 60 MHz but this exceeds the PIC's timing specifications)
Frequency counter with a PIC and minimum hardware by Wolfgang "Wolf" Büscher, DL4YHF - frequency range 1 Hz … 50 MHz
Frequency counter with a PIC and minimum hardware
A flashing decimal point indicates a frequency in kilohertz, a steady point indicates a frequency in Megahertz - which is more common for the intended use in dip meters and QRP transceivers.....
