15 GMRS two-way channels 8 GMRS repeater channels 130–179 (RX only) 400–520 (RX only) ... Features include CTCSS and duplex operation for use with local repeaters
(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 ...
The duplexer is a device which prevents the repeater's high-power transmitter (on the output frequency) from drowning out the users' signal on the repeater receiver (on the input frequency). A diplexer allows two transmitters on different frequencies to use one antenna, and is common in installations where one repeater on 2 m and a second on ...
As of 2016, only low-power (2 W ERP), half duplex GMRS operation is permitted, but a license is not required. [6] Repeater and high-power operations are not permitted. This allows the use of dual-mode FRS/GMRS walkie-talkies, but precludes the use of higher-powered GMRS devices designed for vehicle and base-station purposes..
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.
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.
Boil if you’re using a stovetop method. Once it’s boiling, reduce the heat to a smaller boil so it doesn’t overflow. Cook until you can pierce the potatoes with a fork and it easily slides ...
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
