What frequency do repeaters use?

Repeaters are found mainly in the VHF 6 meter (50–54 MHz), 2 meter (144–148 MHz), 1.25-meter band (11⁄4 meters) (220–225 MHz) and the UHF 70 centimeter (420–450 MHz) bands, but can be used on almost any frequency pair above 28 MHz.

How do you use a repeater frequencies?

To listen to repeater contacts, follow these steps:

  1. Use a repeater directory or website to find a repeater in your area.
  2. Determine the repeater’s input and output frequencies.
  3. Set up your radio to listen on the repeater’s output frequency.
  4. Tune your radio as you do for FM signals.

What is repeater frequency offset?

Offset is the difference between a radio channel’s receive and transmit frequencies. Since in this case the mobile radio transmit frequency (repeater input) is lower than the mobile radio receive frequency (repeater output), it is said to have a negative offset of 600 kHz or -600 kHz.

How far can a radio repeater reach?

A repeater station located in the mountains, for example, may have a range of hundreds of miles, while a repeater located where the terrain is relatively flat, such as here in Southeast Michigan, the range will be more like 50 miles or less.

How far can you talk on a repeater?

Repeaters and FM Repeaters are normally located in high locations such as a tall building or a hill top overlooking expanses of territory. On VHF frequencies such as 2-meters, antenna height greatly influences how far one can talk. Typical reliable repeater range is about 25 miles (40 km).

How far can a wifi repeater reach?

2,500 feet
Without additional help from boosters and such, a router can broadcast a signal within a limited area of about 150 feet (depending on the type of router you have). Boosters, extenders, and repeaters can spread your Wi-Fi signal much farther—up to 2,500 feet.

How far can you talk on a GMRS repeater?

The range for GMRS radios using repeaters can be up to hundreds of miles. GMRS radios share channels 1-7 with the FRS, but have their own specific channels of 15-22.

What is the most common repeater frequency offset in the 2-meter band?

Each amateur band has a designated standard value for the offset, and in the 2-meter band the standard offset is plus or minus 600 kHz (0.6 MHz). The standard offset for the 70-centimeter band is +/- 5 MHz (Question T2A03). The 1.25-meter band offset standard is -1.6 MHz.

How does repeater offset work?

Repeaters use a scheme called full duplex where they can transmit and receive at the same time. To achieve this the receiver and transmit channels are offset sufficiently to enable this to occur. The difference between the repeater transmit and receive channels is called the “offset.”

How far can a HAM repeater reach?

If your signal bounces off of just one repeater, the range can get up to 50 miles. With a strong network of repeaters, a transmission could be daisy-chained to span the country. A repeater can’t receive and transmit at the same time on the same frequency, just like normal transceivers.
