Welcome to The Ladder Line.

It's mostly a blog where I share things about amateur radio and occasionally other things. I haven't written anything here for a while but the following articles still get significant hits.

An Arduino based DDS-60 controller

A recent project has been the building of a digital VFO based around the DDS-60 kit and Arduino controller. It's a useful thing to have either as part of a homebrew transmitter or transceiver or as a piece of test equipment. It can generate RF from 1 to 60 MHz in 1 Hz steps with the stability of a crystal oscillator and can run as a QRSS beacon. It's nothing particularly original and it's not rocket science but it might be helpful for someone wanting to get started with DDS and microcontrollers. It's still a work in progress and I'll be happy if anyone wants to contribute ideas or discussion.
