What frequency do most hams use?
Common Ham Radio Repeater Channel Spacings and Offsets
| Band | Output Frequencies of Each Group (In MHz) |
|---|---|
| 440 MHz or 70 cm (local options determine whether inputs are above or below outputs) | 442 – 445 (California repeaters start at 440 MHz) |
| 447 – 450 | |

What is the calling frequency for 70cm?
FM simplex is allowed on every band where voice communications is allowed. 432.100 MHz is the calling frequency for 70cm SSB, which your rig cannot do.
What are common ham radio frequencies?
They are referred to by their frequency (“14 MHz band”) or wavelength (“20 meter band”). But most beginner’s focus on just two bands: 2 meter / 144-148 MHz and 70 centimeter / 430-440 MHz.
What are simplex frequencies?
Simplex – In the amateur radio context, simplex operation means the radio stations are communicating with each other directly, on the same frequency. Both stations take turns transmitting and receiving on the same frequency with no repeater or other device in between.
What are the 2 meter ham frequencies?
The 2-meter amateur radio band is a portion of the VHF radio spectrum that comprises frequencies stretching from 144 MHz to 148 MHz in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa.
What are the 2-meter ham frequencies?
What is the most popular ham radio digital mode?
Overview
- FT8 – In 2018 it is by far the most popular digital mode for award chasing and working DX.
- Packet – One of the first “modern” digital modes, packet radio transmits data in groups or “packets” of 10s or 100s of bytes.
What frequencies can I use without a ham license?
The Family Radio Server (FRS) authorizes 22 channels in the 462 MHz and 467 MHz range, and it is available without a license. This device can operate outside those frequencies. Using these outside that frequency in the US could land you with fines, loss of device, or worse.
What is the emergency frequency for ham radio?
HAM RADIO COMMON EMERGENCY FREQUENCIES. Most frequencies above 30 MHz are assigned on a local basis. To know where to listen for your local police or fire department, you’ll need a frequency guide or directory for your locality.
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 is ham radio spectrum?
Amateur radio, also known as ham radio, is the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication.
What is a 10 Meter ham?
10 Meter Radios are Amateur Radios, also known as Ham Radios. Unlike a CB Radio, you need to have a license to operate a 10 Meter Radio. The reason for this is because the 10 Meter Radios are allowed to have more wattage/power output than CB Radios. According to FCC regulations, CB radios are allowed a max output of 4 watts.
