I think the idle chit-chat is a big turn-off to a lot of folks who would otherwise be interested in the WorldвЂ™s Greatest Hobbyв„ў, but thankfullyВ there are plenty of ways for the mic-shy to get on the air. There are other articles on this WA7EWC site with more detail on digital mode software.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. New Digital Modes Changing Complexion of Bands and Perhaps of Ham RadioДЄt least some of the other digital modes should continue to see some use as they are more optimized for different kinds of communication (moonbounce, scatter, etc.) There is an interesting article on the ARRL website about the im pact of digital modes. Olivia does not have as many supporting apps as the other digital modes. Unlike FT8, it does not have a fixed message protocol, and allows chatting or even rag chewing. It is like a high performance, weak signal version of PSK31. Olivia вЂ“ Olivia also has its proponents.In addition, FT8 can make contacts for very weak signals, and does not require high transmitter power. Simply clicking on a CQ message can result it a complete contact in a couple of minutes вЂ“ no additional operator input needed. The message protocol is fixed and automated. It uses a fixed 15second message exchange protocol, and can pack a whole bunch of different signals into the standard bandwidth of a USB (upper sideband) signal. FT8 вЂ“ FT8 is a very new mode (first released in mid-2017) that seems to have totally eclipsed other modes such as JT-65 almost overnight.

The software ususally supports a more or less standard sequence of starting messages (QTH, Name, rig, etc.), and then allows hand typed chat. PSK31 вЂ“ this has been and continues to be a popular chat type contacts.Widely used for contesting as well as general chat type contacts. RTTY вЂ“ the granddaddy of them all, now done digitally.In my opinion, at the beginning of 2018, there seems it seems to be down to 3 or 4 dominate modes, at least on the HF bands. Current State of Digital ModesДigital modes seem to come and go. More modern transceivers have a digital connection built in and can connect directly to your computer via a standard USB cable for both the audio and control connections. These can be custom built (hey, hams build stuff, right?), or be a commercially available box. Older rigs typically need extra hardware to interface the computer to the rig. Often, the associated software can also generate control signals for your transceiver (frequency, mode, PTT, etc.) Block Diagram of Computer/Transceiver Interface Some of these modes include RTTY, PSK31, Olivia, JT-65, and the newest, FT8.Д«asically, almost all of the digital modes encode a message (usually text based) into an audio signal that is generated by software on a computer connected to the microphone and speaker signals of your transceiver, transmitted (normally over SSB), and the received signal is then decoded by the software. Over the past few years, there have been a number of digital protocols available, and they have been improving over the years. (We arenвЂ™t talking about the digital protocols used to control repeater networks, etc.) But today (2018), there are a whole bunch of different digital modes based on software that can be used to communicate via keyboard and computer screen. RTTY has long been the standard way to communicate via a keyboard, and could be considered the first вЂњdigitalвЂќ mode.
