Get your radio channels programmed and get on the air with one or more repeaters that suit your needs and your preferences!Necessarily, a repeater must receive and transmit at the same time, albeit on two different frequencies. Complete 2020 Amateur Radio Repeater & Simplex Frequencies . Detailed packet frequencies [PDF] 3. Many operators using mobile stations will tack on “mobile” to their call sign to clarify that they are not at their home station. However, if you do find any mistakes or find that this list needs updating, please email the webmaster with the details.

For the new ham, FM repeater ops are often the first and most common on-air experiences, but accessing repeaters also represents a significant initial vexation for the new ham to overcome. There’s a lot to learn about repeaters, much more than is represented in this brief introduction, but the information here should be sufficient to start the beginner down the path to tons of FM repeater fun! When properly accomplished, your transmission will automatically include the selected continuous tone and the repeater will happily receive your signal. Across all of North America, 446.000 MHz is the National Simplex Frequency (also referred to as the calling frequency). Due to high obstruction, the higher frequencies are desirable. The coordinator recommends repeater pair frequencies and other station parameters to help avoid interference. But repeaters are operated using single sideband mode, digital modes, and HF frequencies, as well.

Any frequencies outside of this band are for COMMERCIAL USE ONLY and all need to be licenced. Choosing an appropriate simplex frequency can be a little tricky, since local practice varies. Repeaters often filter out the CTCSS tone from retransmissions so that it is not heard as audio by receiving stations.Other methods of repeater squelch are sometimes implemented, although in the US CTCSS is the most common. \"Considerate Operator's Frequency Guide\" 2200 and 600 - meter bandsGeneral, Advanced and Amateur Extra class licensees are authorized to use these Amateur BandsAmateurs wishing to operate on either 2,200 or 630 meters must first register with the Utilities Technology Council online at https://utc.org/plc-database-amateur-notification-process/. 1. Band Output Frequencies of Each Group (In MHz) Offset […] The goal is to demystify repeaters and help the newly licensed Technician overcome any initial bewilderment about repeaters. Radio Frequencies (Talk Channels) for Two Way Radio are allocated by the ACMA (Australian Communications Media Authority) which is the Federal Governing body in charge of Licencing of Two Way Radio Frequencies.There are 80 Channels of free UHF CB Two Way Radio Channels that have been set aside for the general public to use. Channels 31 to 38 and 71 to 78 - Repeater inputs - Do not use these channels for simplex … Each station monitors the repeater using a frequency of 447.725 MHz. Until you become accustomed to using repeaters on all the different ham radio bands, this chart can help you remember the right offsets and channel spacings to use. Phone patch, autopatch and HF/VHF/UHF operating guidelines 4. But repeaters are operated using single sideband mode, digital modes, and HF frequencies, as well. A repeater will use a single established tone from a set of 42 standard frequencies. (See A frequency pair offset may be positive (+) or negative (-). In the 2-meter band example in the table above the offset is positive since the talk frequency (147.945 MHz) is higher than the listen frequency (147.345 MHz).This squelch method is known as the Continuous Tone Coded Squelch System, or CTCSS. Further, the duplexer rejects the normal receive frequency on the transmit side, requiring that all received signal strength is directed to the receive side path, while allowing the transmit signal to pass on to the antenna unimpeded.Duplexer cavities for a 2-meter repeater.
