2 meter ham radio frequencies

For repeaters that require a CTCSS tone for repeater access, you will have to set the proper tone frequency on transmit. Obviously, you get more channels on the band with 15 kHz spacing than with 20 kHz, but you have to put up with more adjacent channel interference. Unlike some other long distance modes, high power and large antennas are often not required to make contact with distant stations via a sporadic E event. There are portions of the band designated for repeater outputs(which is the frequency that we tune to receive the repeater) and repeater inputs (which is the frequency we transmit on to use the repeater). In these regions, the allocated 2 meter ham radio frequencies are from 144 MHz to 146 MHz. Considerate Operator's Frequency Guide However, even without repeaters available, the 2-meter band provides reliable crosstown communications throughout smaller towns, making it ideal for emergency communications. In other words, when you can receive a signal from CHU or WWV, it does not necessarily mean that the closest amateur radio band is usable … [11] While the statute specifically states one of the forbidden bands as 150–160 MHz, most two-meter transceivers can tune into this portion of the spectrum at least as receivers, and are therefore unlawful to mount in a motor vehicle in Los Angeles County. The most common VHF radios are basic FM mobile or handheld transceivers. This means it is best to find the specific band plan for your region. For the HF bands, the frequency privileges depend greatly on the license class of the operator. Geographical ... Novice and Technician Plus licensees outside ITU Region 2 may use CW only between 7.050 and 7.075 MHz. It is widely available to Technician basic ham license (or higher) ham operators in USA. This may be a challenge to find the right information, but try searching the web for “2-meter band plan” and your state. 146.400, 146.420, 146.440, 146.460, 146.480, 146.500. Covers Ham HF, 11 meters, CB, SSB, VHF FM, 2 meters, 10 meters, UHF walkie talkies, handy … It is popular among survivalists because it is the only coordinated 2 meter simplex channel compatible with bulletproof military surplus radios (AN/PRC-127, etc) and forest-fire radios (Bendix HTs, etc). ITU Radio Regulations.. See the appropriate Wiki page for further information. Reliable range is very dependent on the height of the repeater antenna and also on the height and surroundings of the handheld or mobile unit attempting to access to the repeater. In many instances 6 meter voice modes are readable but with varying degrees of difficulty when reflected off an aurora. The best known of these are: These and other well-known forms of VHF signal enhancement that allow trans-oceanic and trans-continental contacts on 2 meters are described in the subsections that follow within this section. 2-meter Simplex FM Frequencies by joel Sampson / N5LXI. You might think that the spacing between channels would be 5 kHz, which is the tuning step of most FM radios. Notice that these segments are positioned 600 kHz apart consistent with the standard 2M repeater offset. When operating simplex, use a simplex frequency designated by your local band plan. Amateur radio operators use a variety of modulation techniques to carry out communications. Burlington. 151.625: This channel is used by "itinerant" businesses, or those that travel about the country. In other parts of the country, a 20-kHz spacing has been adopted to provide for more separation between channels. Above 50 MHz, the frequency allocations are the same for Technician licenses and higher. For the Colorado VHF/UHF band plans, see the Colorado Council of Amateur Radio Clubs web site. And the audio usually sounds better than working through a machine.These simplex frequencies are handy to have programmed in your base, mobile and HT transceivers for rag chewing, working FM DX, and emergency communications. A well-placed antenna and high-power equipment can achieve distances of up to a few hundred miles, and fortuitous propagation conditions called "signal enhancements" can on occasion reach across oceans. FM Operating On VHF frequencies such as 2-meters, antenna height greatly influences how far one can talk. The band plan indicates the proper range of frequencies for FM operation but there is more to the story. Such stations are able to communicate 100–300 miles (160–480 km) consistently. 222 MHz or 1-1/4 meters: 223.85 – 224.98 – 1.6 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 – 450 146.52: This frequency is used by ham radio operators for non-repeater communications on the two-meter band; it is very busy in many parts of the country. Signals in this band travel primarily line-of-sight or slightly further. However, a few simple guidelines can help, especially if you are operating only FM. Simple radios for FM repeater operation have become plentiful and inexpensive in recent years. The speed required to confirm a two way contact via a short lived ionized meteor trail can only be performed by fast computers on both ends with very little human interaction. Los Angeles County has a statute (which dates from 1944) concerning mounting a "shortwave receiver" in a motor vehicle. Propagation. Best Ham Radio Frequencies for Long Distance Communication. The typical 2 meter station using CW (Morse code) or SSB (single side band) modes consists of a radio driving a power amplifier generating about 200–500 Watts of RF power. Family 2 Way Radio Frequencies Rail Road F requencies NASCAR Frequencies Global Network Frequencies HF DEA Frequencies Hurricane Frequencies Mystic Star Frequencies New Zealand R&R Frequencies RTTY ... MID-2 Bombay 3467, 5658, 10018, 13288 Delhi 3467, 5658, 10018, 13288 Islamabad 5601, 2923 Typically on 2 meter, the “offset” is 600 kilohertz. 147.00 – 147.39 – 600 kHz – 600 kHz + 600 kHz. These are commonly called the "WARC bands". The typical layout of simplex channels is the table below. This page was last edited on 7 September 2020, at 18:29. The data represents the repeaters frequency, offset, CTCSS, PL and notes such as if it supports IRLP, Echolink, autopatch, etc. Below the calling frequency are 146.505, 146.490, 146.475 MHz and on. The use of channels is especially important for repeaters since they don’t easily move around in frequency and are coordinated to minimize interference. [2][3] The license privileges of amateur radio operators include the use of frequencies within this band for telecommunication, usually conducted locally within a range of about 100 miles (160 km). Graphical Chart ... Novice/Technicians are limited to 200 watts PEP on HF bands. Fast & Free shipping on many items! The fine points of the band plan can be a bit confusing. These radios usually tune the entire 2M band from 144 MHz to 148 MHz in 5 kHz steps. Antennas used for distance work are usually horizontally polarized instead of the vertical polarization customarily used for local contacts. Contains a table showing standard ham radio 2-meter repeater input frequency offsets from output frequencies. Circuses, exhibitions, trade shows, and sports teams are some of the users you can hear. Ham radio Frequency Chart Graphical Frequency Allocations 2200 and 600 - meter bands General, Advanced and Amateur Extra class licensees are authorized to Satellites are basically repeater stations in orbit. There is usually another group of FM simplex frequencies in the 147 MHz. If you are operating on other bands, be sure to check the appropriate band plan before transmitting. Much of 2-meter FM operation uses a radio repeater, a radio receiver and transmitter that instantly retransmits a received signal on a separate frequency. 20, No. Stations that have antennas located in relatively high locations with views (from the antenna) clear to the horizon have a big advantage over other stations. The information on this page represents amateur ham radio repeater locations displayed via Google maps. 145.3125 amateur radio 2 m v25 fm 145.325 amateur radio 2 m v26 fm 145.3375 amateur radio 2 m v27 internet voice gateway fm 145.35 amateur radio 2 m v28 fm 145.3625 amateur radio 2 m v29 fm 145.375 amateur radio 2 m v30 fm 145.3875 amateur radio 2 m v31 fm 145.4 amateur radio 2 m v32 fm 145.4125 amateur radio 2 m v33 fm 145.425 amateur radio 2 m v34 fm This doesn’t work because a typical FM signal occupies a bandwidth that is about 16 kHz wide. An exception to this phenomenon would be the 6 meter band which is significantly lower in frequency than the 2 meter band by 94 MHz. Named for Saint Brendan of Clonfert, the three awards differentiate between successful "traditional" phone/CW contact (the Brendan Trophies), successful "non-traditional" digital two-way contact (the Brendan Shields), and an award for the first verified reception in either direction, regardless of method (the Brendan Plates). Transequatorial propagation also known as (TEP) is a regular daytime occurrence on the 2 meter band over the equatorial regions and is common in the temperate latitudes in late spring, early summer and, to a lesser degree, in early winter. Choosing an appropriate simplex frequency can be a little tricky, since it depends on whether your region uses the 15-kHz or 20-kHz channel spacing. On-board software defines what mode or band is in use at any particular time and this is determined by amateurs at so-called earth stations who control or instruct the satellite behavior. The satellite radio signals are classified into two groups: voice and data tranmissions. 146.400, 146.415, 146.430, 146.445, 146.460, 146.475, 146.490, 146.505. Cape May. For receiving stations located within ± 10 degrees of the geomagnetic equator, equatorial E-skip can be expected on most days throughout the year, peaking around midday local time. moving upward. These "Openings" as they are known, are generally first spotted by amateurs operating SSB (Single Side Band)[6] and CW (Continuous Wave)[7] modes since amateurs using these modes typically are attempting distance contacts (DX) and alert for signal enhancement events. Receiving these very weak return signals, again involves the use of high gain antennas (usually the same ones used to transmit the signal) and a very low-noise front end RF amplifier and a frequency stable receiver. A well-placed antenna and high-power equipment can achieve distances of up to a few hundred miles, and fortuitous propagation conditions called "signal enhancements" can on occasion reach across oceans. It covers 160 m to 17 meter … Summary Listening to the International Space Station (ISS) and satellites in orbit with a focus on radio signals in the amateur radio 2 meter band comprising frequencies from 144.000 MHz to 148.000 MHz. The standard time stations (below) will give you some indication of propagation conditions on ham radio frequencies.But, keep in mind that they transmit at much higher power levels than the ham radio maximum legal power limit!. This extra power is usually fed to a multi-element, compound antenna, usually a Yagi-Uda or Yagi, which can beam most of the signal power towards the intended receiving station. [9] Impressive attempts at the Brendan awards have established contact, but further examination revealed the signal was bounced off the International Space Station.[10]. One computer will send a request for contact and if successfully received by a distant station, a reply will be sent by the receiving stations computer usually via the same ionized meteor trail to confirm the contact. The 2-meter band is a popular choice for digital packet transmission, with 144.39MHz (North America) and 144.8MHz (Europe) commonly used for APRS operation. The data represents the repeaters frequency, offset, CTCSS, PL and notes such as if it supports IRLP, Echolink, autopatch, etc. Beacons are transmitters that are always on, transmitting a short CW message as a propagation indicator for distant stations. 52MHz (6 meter) 144MHz (2 meter) 222MHz (1.25 meter) 440MHz (70 cm) 902 and 1240 MHz; All bands *NEW* All Bands - Digital Mode Repeaters; Pending or Recently Approved Repeaters; Chirp … All classes are limited to 200 watts PEP in the 80, 40, and 15 meter Novice/Technician Plus subbands. Line of sight would be the ultimate in reliability. We often think of 2 Meters as a local coverage band but when conditions are right, contacts can be made with stations over a thousand miles away. EME signals, for example, are usually quite small since the signal has to make the round trip from the earth to the moon and back. It is widely available to Technician basic ham license (or higher) ham operators in USA. While the 2 meter band is best known as a local band using the FM mode, there are many opportunities for long distance (DX) communications using other modes. Repeaters are normally located in high locations such as a tall building or a hill top overlooking expanses of territory. Across all of North America, the National Simplex Frequency (also referred to as the calling frequency) is 146.52 MHz. Scanner Frequencies and Radio Frequency Reference Data for Tennessee Single-sideband (SSB Calling Frequency = 144.200), OSCAR (satellite) APRS Frequency = 144.390 MHz. The ARRL Letter, Vol. One of these modes is JT65 which is a digital mode. These satellites can reach altitudes of 30,000 miles (50,000 km) above the earth where an entire hemisphere is visible providing outstanding communications capabilities from any two points on the earth within line of sight of the satellite; distances that are far beyond the reach of the LEO's. It is widely available to Technician basic ham license (or higher) ham operators in USA. While arrest rarely happens, the statute is still on the books. Of course, conditions are not always right so having a beacon on the other end of the desired communication path lets you know how propagation is in that direction. Since the ionization persists much longer than meteor trails, voice modulated radio signals may sometimes be used, but the constant movement of the ionized gas leads to heavy distortion of the signals causing the audio to sound "ghostly" and whispered. Fun with Satellites presentation at SEA-PAC June 4, 2016 There are also California Penal Code statutes covering similar activities. This is known as cross band repeating. Knowing the FCC frequency authorizations is a good start but we need to check a bit further. It is one of very few ham radio 2 meter frequencies widely coordinated for FM-Simplex-only throughout USA. There are many different frequencies to choose from, so how do you find an appropriate frequency to use? When using a repeater, you just need to dial in the published repeater frequency and set the transmit offset, usually either + 600 kHz or – 600 kHz. FM operation is “channelized”, meaning that specific 2M FM frequencies are identified by the band plan. Sporadic E is a rare and completely random propagation phenomenon lasting anywhere from a matter of minutes to several hours. A two-way conversation can take place over a distance of several hundred miles or more, often using low levels of RF power. Great deals on 2 Meters Ham & Amateur Radio Transceivers. Individual amateur stations are free to use any frequency within authorized frequency ranges; authorized bands may vary by the class of the station license. Yes, you can operate simplex without a repeater on two-meters FM! Two way ducting contacts can have very strong signals and are often made with moderate power, small antennas and other types of modes. Globally, the International Telecommunication Union (ITU) oversees how much radio spectrum is set aside for amateur radio transmissions. [y] This includes a currently active footnote allocation mentioned in the ITU's Table of Frequency Allocations. If a local FM operator fires up in the EME portion of the band, an EME signal that can’t be heard by an FM receiver can be wiped out by the FM signal. 2 meters (a mix of 20 kHz and 15 kHz channel spacing) 145.2 – 145.5 146.61 – 146.97. These allocations may only apply to a group of countries. Typical reliable repeater range is about 25 miles (40 km). Non - Ham Radio Beacons. Occasionally, signal bending in the atmosphere's troposphere known as tropospheric ducting can allow 2 meter signals to carry hundreds or even thousands of miles as evidenced by the occasional 2 meter contact between the west coast of the United States and the Hawaiian Islands, the northeast region to the Florida coast and across the Gulf of Mexico. Recently, however, with new legislation in various states, licensed ham radio operators are exempt from these prohibitions including exemptions from using a radio while driving. CW signals returning from an auroral reflection have no distinct sound or tone but simply sound like a swishing or whooshing noise. Due to the delay of the signal traveling to the moon and back (travel time approx. There are a few amateur satellites that have very high elliptical orbits. 146.745 MHZ split down 146.2 PL. Je kunt via deze repeaters werken met een shift van -600 KHz. This continues until a reply is received to confirm the contact or until no contact can be made and no new requests are sent. Further up the band, we see segments for SSB operation and beacon operation. As shown in the table, the ARRL 2 Meter amateur band plan supports a wide variety of radio operation. In particular, the 2m band extends from 144 MHz to 148 MHz. County. With the exception of sporadic E, directional antennas such as Yagis or log periodic antennas are almost essential to take advantage of signal enhancements. US ... the maximum power output is 1500 watts PEP. We need to use our authorized frequencies wisely by sharing the band with other users and avoiding unnecessary interference. If you’re just starting as a newbie ham, a 100 mile range will already sound good. The typical hand held two meter FM transceiver produces about 5 watts of transmit power. Antennas for repeater work are almost always vertically polarized since 2-meter antennas on cars are usually vertically polarized. Most amateur satellites are Low Earth Orbit satellites, or LEO's as they are affectionately known, and generally are about 450 miles high (700 km). 2 Meter Band Plan Adapted from the ARRL web site: 144.000-144.100: CW: 144.100-144.275: Single-sideband (SSB Calling Frequency = 144.200) 144.275-144.300: Propagation Beacons: 144.300-144.500: OSCAR (satellite) APRS Frequency = 144.390 MHz: 144.500-144.900: FM Repeater Inputs: 144.900-145.100: Packet Radio: 145.100-145.500: FM Repeater Outputs: 145.500-145.800 The OSCAR segments don’t specify a particular modulation type since CW, SSB and FM are all used for OSCAR operation. Covers VLF, 160, 80, 40, 30, 20 and 2 meters. (Edited and re-written by an article from an unknown author) 2 METER BAND PLAN (all frequencies are in megahertz) 144.00-144.05 EME (CW) 144.05-144.10 General CW and weak signals 144.10-144.20 EME and weak-signal SSB 144.200 National calling frequency Note: Federal law preempts many local ordinances and state laws which may prohibit a licensed amateur radio operator from possessing an amateur radio based on its factory ability to receive frequencies outside of ham bands. Amateur Radio Ham Radio Repeater in Google Maps. It is one of very few ham radio 2 meter frequencies widely coordinated for FM-Simplex-only throughout USA. Thus, it makes sense to have a band plan that divides the band up into segments for each type of operation. Depending on the intensity of the ionized meteor trail, multiple contacts from multiple stations can be made off the same trail until it dissipates and can no longer reflect VHF signals with sufficient strength. For instance, a favorite mode is Mode "B" or "V/U" which simply indicates the uplink and downlink frequencies or bands the satellite is currently using. The FCC Rules say that any mode (FM, AM, SSB, CW, etc.) In most instances using auroral reflections on 2 meters, audio or voice is totally unintelligible and ham operators wishing to make contacts via aurora, must resort to CW (Morse code). In areas that use 20 kHz channels, the frequencies are 146.540, 146.560, 146.580 MHz moving up and 146.500, 146.480, 146.460 MHz moving down. In this example, V/U means VHF/UHF or VHF uplink with UHF downlink. Using this high speed digital mode, a full two way contact, can be completed in one second or less and can only be validated using a computer. When a well-equipped station with its antenna well-located “high and in the clear” is operating during a signal enhancement, astonishing distances can be bridged, momentarily approaching what is regularly possible on shortwave and mediumwave. The FCC has restricted 144.0 to 144.100 MHz to CW operation only. This mode is often called burst transmission and can yield communication distances similar to sporadic E as described above. You will also need to know if this is a plus or minus offset which indicates if the 600 kHz is added to the repeater’s … The mode is more efficient than FM when signals are weak, so it is the way to go when you are trying to push the limits of 2M DX. Due to the distance involved and the very high path loss getting a readable signal bounced off the moon involves high power ~1,000 Watts and steerable high gain antennas. Several regional frequency coordinators recognize 223.5000 as the national 1.25m band FM simplex calling frequency. Another form of VHF propagation is called Sporadic E propagation. This prompted me to develop a set of tables for the 2-meter band which demonstrate how different types of station setups can be expected to perform.
