What is the offset on a repeater?
The offset is the shift the radio will do when you transmit. VHF and UHF repeaters are listed in megahertz, and 600 kilohertz is 0.6 MHz, so you add or subtract 0.6 to the repeater frequency as needed to get the transmit frequency.
What is the normal offset of 2m repeaters?
Standard 2-Meter Amateur Radio Repeater Input Frequency Offsets
| 2-Meter Repeater Output Frequency | Standard Input Frequency Offset |
|---|---|
| 146.0 MHz – 146.4 MHz | +600 kHz |
| 146.6 MHz – 147.0 MHz | -600 kHz |
| 147.0 MHz – 147.4 MHz | +600 kHz |
| 147.6 MHz – 148.0 MHz | -600 kHz |
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.”
What is frequency offset ham radio?

What is the offset for 6 meter repeaters?
6. Conventional and trunked repeaters between 935-940 MHz have a -39 MHz offset.
What is offset on Baofeng?
The offset is the difference between the repeater’s receive frequency and the transmit frequency. On the 2-meter band, the standard offset is 600 kHz. CTCSS tones allow repeaters o receive particular signals and reject others.
What is the offset for 70cm?
| Band | Frequency Range (MHz) | Offset |
|---|---|---|
| 70cm Ham (repeater subband) | 440-450 | +5 MHz or -5 MHz |
| UHF Canadian border area | 420-430 | +5 MHz |
| UHF | 450-470 | +5 MHz |
| UHF T | 470-512 | +3 MHz |

What is a repeater offset?
AZ Repeaters Repeater Offsets. Offset is the difference between receive and transmit frequencies of a radio channel. Most commonly it refers to the separation between the input frequency and output frequency of a repeater or other type of full duplex system. This should not be confused with the trunking offset required when programming certain…
What is the frequency of ham radio?
Ham radio typically refers to the amateur use of various radio frequencies, including bands within the high frequency (HF), very high frequency (VHF) and ultra high frequency (UHF) ranges. An HF ham radio can specifically receive and transmit within the high frequency range, which is typically designated as being between three and 30 MHz.
What are ham radio repeaters?
A ham radio repeater is a device that links a weak FM radio signal to a stronger VHF signal and transmits it hundreds of miles.
How does a ham radio system work?
Ham radios have been used to communicate via everything from morse code to voice and now even digital transmissions. Ham radios work by tapping into various radio frequencies just above the AM spectrum. The actual frequencies individuals use can be divided into three basic types of bands, VHF, UHF, and Microwave.
