ARRL Ohio Section: Technical Coodinator.
The ARRL divides the United States and its territories into 71 administrative sections. Many sections are comprised of a single state, but a few of the larger states, such as Texas or California, are divided into two more sections.
The membership in each section elects a Section Manager (SM) once every two years. The SM is responsible for managing the Field Organization programs in their section. Through coordinators, the SM recruits ARRL volunteers to staff various crucial program areas.

The ARRL Technical Coordinator (TC) is a section-level official appointed by the Section Manager to coordinate all technical activities within the section.
For a section team to be effective in one of the most important arenas in Amateur Radio, technology, there must be a cadre of qualified, competent Technical Specialists (TS).
"Advancement of the radio art" is a profound obligation we incur under the rules of the FCC.
TSes help meet this obligation.
TS supports the TC in two main areas of responsibility:
Radio Frequency Interference and Technical Information.
Technical Specialist can specialize in certain specific technical areas, or can be generalists.
Your guess is as good as mine.
We play around with stuff!!!

The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python...
...It's capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games. What’s more, the Raspberry Pi has the ability to interact with the outside world, and has been used in a wide array of digital maker projects.
from: What Is A Raspberry Pi?
Eben Upton, designer of the Raspberry Pi noticed the slide in skill levels while working at Cambridge University's Computer Laboratory in 2006.
Students applying to study computer science had far less experience than previous students.

Eben and his colleagues came up with the idea of creating a computer, that came with necessary tools, sold for $25, was robust enough to survive a children's book bag, that did interesting things, and drew people to use it.

The Raspberry Pi was designed to inspire children to take-up programming, but the vast majority of the £25 computers have been bought by adults.
"The reason we've sold so many of these (over a million) is largely is that they've sold to technology capable adults more than they've sold to kids," Upton said. "We think only 10-20%, maybe 30% of the ones we sold have ended up in the hands of kids."

Digital is a binary representation of some data (1's and 0's).
Encoded in a structure before transmission.
Digital is a very broad term and takes many forms:

Wide spread ownership of personal computing devices allows amateurs to develop and use these modes for communication purposes. This includes smartphones and tablets.
When compared to voice communications, digital can be:
Each mode has applications, uses, advantages, and disadvantages.

NBEMS stands for Narrow Band Emergency Messaging System (or Software).
Established standards for passing email and text-based traffic over Amateur Radio.
