= | =Base Station (aka "fixed station")= | ||
A fixed ground station, usually using utility power and one or more external antennas. | |||
An amateur radio station is a radio station designed to provide radiocommunications in the amateur radio service for an amateur radio operator. Radio amateurs build and operate several types of amateur radio stations, including fixed ground stations, mobile stations, space stations, and temporary field stations. | |||
[https://en.wikipedia.org/wiki/Amateur_radio_station More on Amateur Radio Station at Wikipedia.org] | |||
An amateur radio station established in a permanent structure with equipment that is not intended for portable operation is referred to as a fixed station. This is the most common form of amateur radio station, and can be found in homes, schools, and some public buildings. A typical fixed station is equipped with a transceiver and one or more antennas. For voice communications, the station will be equipped with a microphone; for communications using the Morse code, a telegraph key is common; and for communications over digital modes such as RTTY and PSK31, a station will be equipped with a specialized interface to connect the transceiver to a computer sound card. While not a requirement for radiocommunications, most fixed amateur radio stations are equipped with one or more computers, which serve tasks ranging from logging of contacts with other stations to various levels of station hardware control. Fixed stations might also be equipped with amplifiers, antenna rotators, SWR meters, and other station accessories. | |||

Morse code is a method of sending text messages by keying in a series of electronic pulses, usually represented as a short pulse (called a "dot") and a long pulse (a "dash"). The code was devised by Samuel F. B. Morse in the 1840s to work with his invention of the telegraph, the first invention to effectively exploit electromagnetism for long-distance communication. The early telegrapher, often one who was at a railroad station interconnected with others along miles of telegraph pole lines, would tap a key up and down to send a succession of characters that the receiving telegrapher could read from tape (later operators learned to read the transmissions simply by listening). In the original version, the key down separated by a pause (key up) from the next letter was a dot (or, as it sounded to the telegrapher, a "dit") and the key down quickly twice in succession was a dash (a "dah" or "dit-dit"). Each text character was represented by a dot, dash, or some combination. | |||

ARL (ref. NTS): ARRL Numbered Radiograms
Numbered messages have been established for some of the more common texts sent during emergencies and holiday seasons. When this common text can be used, an ARL NUMBER is substituted for the text and sent. The delivering station reads the actual text to the address, not the ARL NUMBER. The letters ARL are inserted in the preamble in the check and in the text before spelled out numbers, which represent texts from this list. Note that "ARL" is included in the text before spelled out numbers, which represent texts from this list. Note that some ARL texts include insertion of numerals or words.

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. The ARRL web site
Balun
an electrical device that converts between a balanced signal (two signals working against each other where ground is irrelevant) and an unbalanced signal (a single signal working against ground or pseudo-ground). More at Wikipedia.org
Band
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.
Band Plan
A bandplan or band plan is a plan for using a particular band of radio frequencies, that are a portion of the electromagnetic spectrum. Each band plan defines the frequency range to be included, how channels are to be defined, and what will be carried on those channels. What's the Band Plan for Western Washington Amateur Radio? WWARA.org web site More about Bandplan at Wikipedia.org
Base Station (aka "fixed station")
A fixed ground station, usually using utility power and one or more external antennas. An amateur radio station is a radio station designed to provide radiocommunications in the amateur radio service for an amateur radio operator. Radio amateurs build and operate several types of amateur radio stations, including fixed ground stations, mobile stations, space stations, and temporary field stations.
More on Amateur Radio Station at Wikipedia.org
An amateur radio station established in a permanent structure with equipment that is not intended for portable operation is referred to as a fixed station. This is the most common form of amateur radio station, and can be found in homes, schools, and some public buildings. A typical fixed station is equipped with a transceiver and one or more antennas. For voice communications, the station will be equipped with a microphone; for communications using the Morse code, a telegraph key is common; and for communications over digital modes such as RTTY and PSK31, a station will be equipped with a specialized interface to connect the transceiver to a computer sound card. While not a requirement for radiocommunications, most fixed amateur radio stations are equipped with one or more computers, which serve tasks ranging from logging of contacts with other stations to various levels of station hardware control. Fixed stations might also be equipped with amplifiers, antenna rotators, SWR meters, and other station accessories.

Cross-band Repeater
Cross-band repeating is a relatively inexpensive means for extending the range of handheld radios. Many mobile-type dual-band radios (VHF/UHF) can receive signals on one band, and simultaneously re-transmit on the other band. With the proper settings, a dual-band FM mobile can "repeat", for example, signals heard from a VHF repeater at some distance away, to a UHF handie-talkie carried by an Operator inside a building, or down in a ravine, as well as in the other direction.

Morse Code (aka "CW")
Morse code is a method of sending text messages by keying in a series of electronic pulses, usually represented as a short pulse (called a "dot") and a long pulse (a "dash"). The code was devised by Samuel F. B. Morse in the 1840s to work with his invention of the telegraph, the first invention to effectively exploit electromagnetism for long-distance communication. The early telegrapher, often one who was at a railroad station interconnected with others along miles of telegraph pole lines, would tap a key up and down to send a succession of characters that the receiving telegrapher could read from tape (later operators learned to read the transmissions simply by listening). In the original version, the key down separated by a pause (key up) from the next letter was a dot (or, as it sounded to the telegrapher, a "dit") and the key down quickly twice in succession was a dash (a "dah" or "dit-dit"). Each text character was represented by a dot, dash, or some combination. More on Morse Code at Wikipedia.org More on CW at Amateur-Radio-Wiki.net
NBEMS
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.
