AGM (absorbed glass mat) is a special design glass mat designed to wick the battery electrolyte between the battery plates. AGM batteries contain only enough liquid to keep the mat wet with the electrolyte and if the battery is broken no free liquid is available to leak out.
A less common definition is radio receiver and transmitter implementations that are based on digital signal processing, but may transmit or receive analog radio transmission standards, for example FM radio. 
Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time tactical digital communications of information of immediate value in the local area. In addition, all such data are ingested into the APRS Internet System (APRS-IS) and distributed globally for ubiquitous and immediate access. more on APRS at Wikipedia.org more at APRS.org more at Amateur-Radio-Wiki.net
The Amateur Radio Emergency Service® (ARES) consists of licensed amateurs who have voluntarily registered their qualifications and equipment, with their local ARES leadership, for communications duty in the public service when disaster strikes.
ARL (ref. NTS): ARRL Numbered Radiograms
ARRL: Amateur Radio Relay League, ("The League")
ARRL is the national association for Amateur Radio in the US. Founded in 1914 by Hiram Percy Maxim as The American Radio Relay League, ARRL is a noncommercial organization of radio amateurs. ARRL numbers within its ranks the vast majority of active radio amateurs in the nation and has a proud history of achievement as the standard-bearer in amateur affairs. ARRL’s underpinnings as Amateur Radio’s witness, partner and forum are defined by five pillars: Public Service, Advocacy, Education, Technology, and Membership.
Call Sign (FCC-assigned)
Co-ax (cable): Co-Axial Shielded Cable, used for Antenna connections.
Conventional system is the most basic radio communications system. Conventional, as its name implies, refers to a "traditional" method of frequency utilization. Conventional radios operate on fixed channels and each user group is permanently assigned a fixed frequency or a set of frequencies. more at About2wayRadio.com
Cross-band repeating is a relatively inexpensive means for extending the range of handheld radios. more at CVARC.org
"Continuous Wave" aka Morse Code transmission
a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale. (in general use) a degree of loudness.
"his voice went up several decibels"
Today the most common meaning is digital radio broadcasting technologies. In these systems, the analog audio signal is digitized, compressed using formats such as mp2, and transmitted using a digital modulation scheme.
simultaneous transmission and reception; e.g. Landline or Cellular Telephone
EchoLink is a computer-based Amateur Radio system distributed free of charge that allows radio amateurs to communicate with other amateur radio operators using Voice over IP (VoIP) technology on the Internet for at least part of the path between them.
An experienced Ham who helps a New Ham.
EME: Earth-Moon-Earth radio-signal reflection, aka "Moon-Bounce"
The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security, initially created by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders on April 1, 1979.  Specific to EmComm: ICS online Education and Testing \[see "ICS"\]
(of a communications system or computer circuit) allowing the transmission of signals in both directions but not simultaneously.
"High Frequency", usually refers to below 50 MHz
"Handie-Talkie", a hand-held radio.
Incident Command System
The Internet Radio Linking Project, also called IRLP, is a closed-source project that links amateur radio stations around the world by using Voice over IP (VoIP). Each gateway consists of a dedicated computer running custom software that is connected to both a radio and the Internet.

"I\’m hearing you through the machine just fine!"
Mag-Mount Antenna (magnetic, non-permanent base)
Morse Code \[aka "CW"\]
CW \[Continuous Wave\] is Morse Code, a way to communicate with Dots and Dashes over long distances or with computers by light, wire or radio. 
Narrow Band Emergency Messaging Software (NBEMS) is an Open Source software suite that allows amateur radio operators to reliably send and receive data using nearly any computer (Windows, Mac, and Linux) and any analog radio without requiring a dedicated digital infrastructure or specialized modem hardware. NBEMS works on both VHF/UHF FM and on HF.

NTS: National Traffic System
The National Traffic System (NTS) is an organized network of amateur radio operators sponsored by the American Radio Relay League for the purpose of relaying messages throughout the US and Canada.

Sealed Lead-Acid Battery
A VRLA battery (valve-regulated lead-acid battery), more commonly known as a sealed battery or maintenance free battery, is a type of lead-acid rechargeable battery. Due to their construction, they can be mounted in any orientation, and do not require constant maintenance.

Simplex: direct between 2 or more radios, no repeater involved. Simplex communication is a communication channel that sends information in one direction only. A "duplex" communication channel requires two simplex channels operating in opposite directions. 
In telecommunication, a band - sometimes called a frequency band - is a specific range of frequencies in the radio frequency (RF) spectrum, which is divided among ranges from very low frequencies (vlf) to extremely high frequencies (ehf). Each band has a defined upper and lower frequency limit. 
"TA": commercial radios use "Talk-Around" to refer to bypassing the repeater, i.e., Simplex Communication, direct radio-to-radio. Generally a "TA" switch on the radio itself.
The concept of "trunking" is taken from telephone company technology and practice. It refers to the sharing of common "resources" among a number of different users on the same system without overhearing or interfering with each other\’s conversations. Trunked takes advantage of the probability that in any given number of user units, not everyone will need "resources" access at the same time. Therefore with a given number of users, fewer discrete "resources" are required.
