How does a simplex repeater work?
A type of system known as a simplex repeater uses a single transceiver and a short-duration voice recorder, which records whatever the receiver picks up for a set length of time (usually 30 seconds or less), then plays back the recording over the transmitter on the same frequency. A common name is a “parrot” repeater.
Can anyone use a GMRS repeater?
Typically, handheld GMRS units use lower frequencies to communicate with each other when possible, and transmit on the upper frequencies (while listening 5 MHz lower) to talk to a repeater. This allows anyone listening on the “462” side to hear traffic both from handhelds as well as from anyone using the repeater.
Does a GMRS repeater require a license?
In simple terms, the repeater does not need to auto ID if it’s a intended for use as a private or closed repeater system. Consider, for instance, a family farm or ranch. Since a GMRS license covers the entire family, the repeater does not have its own callsign.
Can anyone use a radio repeater?
Most repeaters are open — that is, available for use by anyone in range. Some repeaters, however, have limited access. Their use is restricted to exclusive groups, such as members of a club. Such closed repeaters require the transmission of a continuous subaudible tone or a short “burst” of tones for access.
Is repeater full duplex?
Repeaters operate in full duplex mode, because they receive and transmit at the same time. The repeater user is usually operating in half duplex, using two frequencies but switching between transmit and receive.
How far will a repeater reach?
roughly 25 miles
Repeaters within signal range of each other cannot transmit on the same frequency and PL tone without causing interference. Repeater range is roughly 25 miles. Areas of higher network usage require more repeaters than areas of less network usage in order to provide coverage for all operators and minimize interference.
