I have been a hobbyist and maker for almost 15 years now. I like inventing things and diving into low-level things. In , I was looking at a protocol called NBP , used to create a data network over amateur radio links. NBP was developed in the s as a potential replacement for the venerable AX.
Getting Started In Amateur Radio Data Modes. - Off Grid Ham
Working amateurs around the world using data is a fascinating part of the ham radio hobby, and is definitely worth considering. On this page, we look at what the various amateur radio data modes offer, and how to get started using data. The key to working data modes is to get the audio levels to and from the computer to be ideal:. Level into computer: Make sure that the software is getting the right audio level from the computer. You may need to adjust the soundcard volume, input volume on the software, or the level from the Interface. Level from the computer: You need to make sure that the audio leaving the computer is of the correct volume and not distorting.
One of the primary concerns of radio amateurs who operate with alternative energy is something I call communications efficiency , or, getting the most signal you can for the input power. A lot of fuss, maybe too much, is spent on squeezing every last watt out of our solar panels, generators, and batteries, but not much thought is put into how well our chosen transmission mode uses that power. Some HF transmission modes are inherently more efficient than others. Today we will discuss the rationale for operating amateur radio data modes, the pros and cons as they apply to the off grid ham, and factors to consider before getting started.
This diversity of supported equipment enables hams to choose the right gear for a given situation and budget. This improvement is significant in that it enables AREDN firmware to benefit from the many bug fixes, security improvements and feature enhancements provided by OpenWRT developers from around the world. OpenWRT explains that their main goal for this target is to bring the code into a form that will allow all devices to run a standard unpatched Linux kernel. This will greatly reduce the amount of customization required and will streamline the firmware development process. You may notice that the AREDN download page has firmware for these two targets, and you should select the latest
