1750Hz tone generator using 74HC4060
https://www.electronics-lab.com/1750hz-tone-generator-using-74hc4060/
Dilshan Jayakody published a new mini circuit. He writes: The 1750Hz tone bursts are often used to trigger repeaters. There are several methods to build 1750Hz tone generators which including TC5082 divider, using MCUs, etc. In this post, I present another 1750Hz tone generator which I built using 74HC4060 high-speed 14-stage binary ripple counter and […]
