The following is a list of the modes of radio communication used in the amateur radio hobby. Amateurs use a variety of voice, text, image, and data communications modes over radio. Generally new modes can be tested in the amateur radio service, although national regulations may require disclosure of a new mode to permit radio licensing authorities to monitor the transmissions. Encryption , for example, is not generally permitted in the Amateur Radio service except for the special purpose of satellite vehicle control uplinks. The following is a partial list of the modes of communication used, where the mode includes both modulation types and operating protocols.

Amateur Radio Digital Modes » Electronics Notes
There used to be a time when amateur radio was a fairly static pursuit. There was a lot of fascination to be had with building radios, but what you did with them remained constant year on year. By contrast the radio amateur of today lives in a fast-paced world of ever-evolving digital modes, in which much of the excitement comes in pushing the boundaries of what is possible when a radio is connected to a computer. NPR is intended to bring high bandwidth IP networking to radio amateurs in the 70 cm band, and it does this rather cleverly with a modem that contains a single-chip FSK transceiver intended for use in licence-free ISM band applications. There is an Ethernet module and an Mbed microcontroller board on a custom PCB, which when assembled produces a few hundred milliwatts of RF that can be fed to an off-the-shelf DMR power amplifier.
Getting Started with Data Modes
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.
