But amateur digital communication began in earnest in the late 's if you don't count Morse as a digital mode! There are too many different modes to list individually, but here are some of the major ones:. Secure Site Login Forgot Password?
Ham Radio Digital Modes
Getting started with data modes | Essex 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.
These digital modes provide a very interesting way in which to communicate over ham radio, offering different challenges to those presented by the more traditional modes of transmission. What can be thought of as the first of the family of digital modes was RTTY - radio teletype. Originally this used large and heavy mechanical teleprinters or teletypes. With the introduction of computers in the home, these teleprinters became redundant and it was possible to incorporate much greater levels of flexibility. This also saved a significant amount of space, a commodity often short in ham radio stations.
In a recent article , I lamented my distaste for carrying on the classic amateur radio conversation — calling CQ, having someone from far away or around the block call back, exchange call signs and signal reports and perhaps a few pleasantries. The difference between the two terms is mostly not important to our discussion, though, and in practice a lot of hams use the terms interchangeably. But for completeness, modulation is a way of impressing information on a radio wave, and a mode is a way of using a modulation to communicate. Modes include continuous wave CW , analog voice, digital voice, images, and data. Yes, there are applications that will translate keystrokes to Morse and back, but that just feels like cheating.
