CTCSS? DCS? Sub-channels? Yes, Continuous Tone Coded Squelch System. Introduced by Motorola in the early 1960s, as “Private Line” (also known as GE/Ericsson’s “Channel Guard”, E.F. Johnson’s “Call Guard”, RCA’s “Quiet Channel”), known by many as simply “tone squelch”. This is like a mains hum on the modulation, a constant musical note… almost as if

The Continuous Tone Coded Squelch System, commonly referred to as CTCSS, has been in used in the land mobile radio arena from the late 1960’s. It is known by a number of different trade names such as Private Line® (PL) by Motorola, Channel Guard® (CG) by General Electric and generically as tone squelch. It is

CTCSS is a system whereby a (not really) sub-audible tone is encoded into the transmit audio of a radio and a receiver on another radio on that frequency will only open up (decode) when it picks up that specific tone. While the tones are called “sub-audible”, most people can hear them as a hum in

There are many different types of vertical antenna or vertical aerial that can be used. These vertical antennas are used in a variety of applications, often as a result of their omnidirectional radiation pattern in the horizontal plane. Vertical antenna advantages There are several reasons why vertical antennas are used as they offer advantages that

1.easy to use If you’re new to two-way radios, or you have budget constraints, you may not need an advanced technical model. For less technical users, radios with pre-programmed channels will be the easiest way to begin radio communication. For these entry-level radios, we recommend one person on the team coordinate the radios and program

The dipole antenna or dipole aerial is one of the most important and commonly used types of RF antenna. The dipole aerial or antenna is widely used on its own, but it is also incorporated into many other RF antenna designs where it forms the radiating or driven element for the overall antenna. The dipole
