DL4YHF - Ham Radio and Homebrew

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" B├╝scher, DL4YHF - frequency range 1 Hz … 50 MHz

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.....
