Communication is very important during an SHTF. A few bits of clarification: QSL: This is a Q signal (see Q signal) that stands for acknowledged receipt of message. A carrier squelch or noise squelchis the most simple variant of all. The 2-meter band’s offsets are set 600 kHz apart (As a rule of thumb), The 70 cm band offsets are 5MHz apart (again, rule of thumb). Rag Chew: This refers to a longer casual conversation between two ham radio operators. How to find ham radio call signs available to you. Repeaters are designed to not transmit noise and spurious signals. This channel should not be used to chew rag (talk) on, but only to sync up with another HAM. Also known as a clarifyer. Discussion of “channels” is misleading since amateur radio focuses on frequency, not an organizational scheme of specific frequencies labelled as “channels”. Antenna Gain: An increase in the antenna transmission and the reception performance in a particular direction with the expense of performance in other directions, performance will increase as compared to an isotropic antenna and a dipole antenna. DSP: Digital Signal Processing – is a processing method of filtering and noise reduction, also otherwise modifying received signals done by converting received signals into the digital form for manipulations. Second, it is especially useful during emergency situations. Basically, it handles the repeater station ID using either voice or CW and activates the transmitter at the appropriate times. Thanks a bunch. The CTCSS tone acts as an access method required to activate HAM radio repeaters.

They also lessen the annoyance of hearing other conversations when using a shared two-way radio communications channel. The mostcommon frequencies for local communication in these bands are: 1. During the daylight it is two layers, F1 and F2 present. Accordingly, please follow FCC rules and repeater operator’s conventions for their systems for the betterment of all. Today, CTCSS tones are almost universally used to access HAM radio repeaters. This occurs along a pipe that is created through a temperature inversion in the lowest part of the atmosphere. Line of Sight Propagation: Are radio frequency paths of travel that are referring to a straight line path from one radio station to another station. Picket Fencing: Picket fencing is when there is a rapid fluctuation in sound or a signal that is caused by a radio station that is moving during a transmission. the sideband is made of frequencies that are higher than the carrier frequency the transceiver is tuned to. HAM RADIO TERMS GLOSSARY This is glossary contains general definitions of typical amateur radio terms. Repeaters are much more complicated and expensive to setup due to a whole host of factors. Q-signals or codes are a set of abbreviations for common radio information that can help save time and allow communication between operators who don’t speak a common language. The signal must also have a tone to determine that the station being received at the repeater wants its transmission to be re-radiated. The good news is, that most of the HAM radios sold today, will set the offset automatically, once you have chosen your desired operating frequency. Learn more. Oscillator: These are circuits that are typically being employed as an inductor and also a capacitor that is used for producing an alternating current of a desired radio frequency. Glen Zook, K9STH, posted this to the Heathkit mailing list: Many amateurs already know that "73" is from what is known as the "Phillips Code", a series of numeric messages conceived for the purpose of cutting down transmission time on the old land telegraph systems when sending text that is basically the same.
