(2) Shared FRS and GMRS simplex; GMRS repeater output. (3) GMRS repeater input. The output frequency of this repeater input is the input frequency minus 5 MHz. (4) FRS transmissions are limited to bandwidth of 11 kHz with a transmitter deviation of +/- 2.5 kHz. Channels are on 12.5 kHz centers. (5) GMRS transmissions may have a bandwidth of 16 ...
While radios designed for the Taiwan market have FRS/GMRS frequencies as part of their channel plan, it is still technically illegal to use equipment designed for the Taiwan market in the United States. FRS, 14 channels, 12.5 kHz spacing: 467.5125 MHz; 467.5250 MHz; 467.5375 MHz; 467.5500 MHz – US GMRS Repeater Ch 15/23 Input
An SSTV repeater is an amateur radio repeater station that relays slow-scan television signals. A typical SSTV repeater is equipped with a HF or VHF transceiver and a computer with a sound card, which serves as a demodulator/modulator of SSTV signals. SSTV repeaters are used by amateur radio operators for exchanging pictures.
Motorola T5320 FRS handheld radio. The Family Radio Service (FRS) is an improved walkie-talkie radio system authorized in the United States since 1996. This personal radio service uses channelized frequencies around 462 and 467 MHz in the ultra high frequency (UHF) band.
In same-band repeaters, isolation between transmitter and receiver can be created by using a single antenna and a device called a duplexer. The device is a tuned filter connected to the antenna. In this example, consider a type of device called a band-pass duplexer. It allows, or passes, a band, (or a narrow range,) of frequencies.
These satellites can be used free of charge by licensed amateur radio operators for voice (FM, SSB) and data (AX.25, packet radio, APRS) communications. Currently, over 18 fully operational amateur radio satellites are in orbit. [2] They may be designed to act as repeaters, as linear transponders, and as store and forward digital relays.
A radio repeater usually consists of a radio receiver connected to a radio transmitter. The received signal is amplified and retransmitted, often on another frequency, to provide coverage beyond the obstruction. Usage of a duplexer can allow the repeater to use one antenna for both receive and transmit at the same time.
