All US amateur radio callsigns start with …
All US amateur radio callsigns start with one or two letters, followed by a number (0-9), and then followed by 1 to 3 letters.
APRS
APRS: Automatic Packet Reporting System
APRS is digital communications information channel for Ham radio. As a single national channel (see map at right), it gives the mobile ham a place to monitor for 10 to 30 minutes in any area, at any time to capture what is happening in ham radio in the surrounding area.
Tactical call …
Give examples.
Tactical call signs are commonly used to simplify communications in an emergency or service net, such as a race or a parade. Some examples of a tactical callsign that might be used would be: “Race Headquarters”, “Shadow” (for the operator who is with the race director), “700 east” (street name where they are located), “net control” (for station coordinating the net), etc.
CQ
CQ
CQ is a code used by wireless operators, particularly those communicating in Morse code, but also by voice operators, to make a general call. Transmitting the letters CQ on a particular radio frequency is an invitation for any operators listening on that frequency to respond. It is still widely used in amateur radio.
CTCSS
CTCSS
Continuous Tone-Coded Squelch System
In telecommunications, Continuous Tone-Coded Squelch System or CTCSS is one type of circuit that is used to reduce the annoyance of listening to other users on a shared two-way radio communications channel. It is sometimes referred to as tone squelch. It does this by adding a low frequency audio tone to the voice.
Transverter
Transverter
In radio engineering, a transverter is a radio frequency device that consists of an upconverter and a downconverter in one unit. Transverters are used in conjunction with transceivers to change the range of frequencies over which the transceiver can communicate.
