2 meter ham radio frequencies

 

2 Meter Band Plan 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. 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. Graphical Chart ... Novice/Technicians are limited to 200 watts PEP on HF bands. To communicate over the longest distances, hams use moon bounce. 2-meter Simplex FM Frequencies by joel Sampson / N5LXI. The first thing we need to know are the frequencies that the FCC has authorized for our particular license class. If you’re just starting as a newbie ham, a 100 mile range will already sound good. De volgende (analoge) repeaters zijn te vinden op de 2 meter band tussen 144 en 146 MHz. At that height amateurs can expect reception distances of up to around 3,000 miles (4,800 km). We need to use our authorized frequencies wisely by sharing the band with other users and avoiding unnecessary interference. This means it is best to find the specific band plan for your region. Covers VLF, 160, 80, 40, 30, 20 and 2 meters. It covers 160 m to 17 meter … This is particularly a problem with FM receivers, which won’t even notice low-level CW and SSB signals. moving upward. New Jersey. In other parts of the country, a 20-kHz spacing has been adopted to provide for more separation between channels. [5] In the US, that role in emergency communications is furthered by the fact that most amateur-radio operators have a 2-meter handheld transceiver (HT), handie-talkie or walkie-talkie. In some parts of North America, non-standard repeater offsets may be used, which will be indicated in the repeater directory. It is usual for them to be heard at distances far beyond line of sight on a daily basis without help from signal enhancements. Often, these modulation techniques are incompatible since a signal of one type can’t be received by a radio set to another modulation type. [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. 2 meter, 440 Simplex Frequency Band Frequency Band Frequency 2 m Simplex 146.400 Mhz 440 Simplex 445.9125 Mhz 2 m Simplex 146.415 Mhz 440 Simplex 445.925 Mhz 2 m Simplex 146.430 Mhz 440 Simplex 445.9375 Mhz 2 m Simplex 146.445 Mhz 440 Simplex 445.950 Mhz Circuses, exhibitions, trade shows, and sports teams are some of the users you can hear. Similarly, an operator chatting across town on 2M could interfere with a satellite hundreds of miles away and not know it. 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. All classes are limited to 200 watts PEP in the 80, 40, and 15 meter Novice/Technician Plus subbands. 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 … Typically on 2 meter, the “offset” is 600 kilohertz. 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. 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. Fast & Free shipping on many items! However, new and recent technological advances in weak signal detection has allowed the successful reception of signals off the moon using much smaller or less well equipped stations allowing reception of signals that are "in the noise" and not audible to the human ear. The idea is to have all stations use frequencies that are spaced just far enough apart to accommodate the signal without interfering with the adjacent channels. Typical reliable repeater range is about 25 miles (40 km). This page was last edited on 7 September 2020, at 18:29. Another form of VHF propagation is called Sporadic E propagation. Sharing spectrum with other services a ham radio reality. This may be a challenge to find the right information, but try searching the web for “2-meter band plan” and your state. Several regional frequency coordinators recognize 223.5000 as the national 1.25m band FM simplex calling frequency. Camden . Amateur (Ham) Radio Frequency Table General Advanced Extra CW, RTTY, Data SSB(Phone), CW, Image 28.000 - 28.300 Mhz 28.300 - 29.700 Mhz Novices and Technicians are limited to 200 watts PEP output on 10 meters. We’ve only covered the 2 Meter band in this article. The information on this page represents amateur ham radio repeater locations displayed via Google maps. The satellite radio signals are classified into two groups: voice and data tranmissions. 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. [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). (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 [w] HF allocation created at the 1979 World Administrative Radio Conference. This doesn’t work because a typical FM signal occupies a bandwidth that is about 16 kHz wide. The most common VHF radios are basic FM mobile or handheld transceivers. 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. The data represents the repeaters frequency, offset, CTCSS, PL and notes such as if it supports IRLP, Echolink, autopatch, etc. Contains a table showing standard ham radio 2-meter repeater input frequency offsets from output frequencies. 146.745 MHZ split down 146.2 PL. US Amateur Radio Frequency Allocations. If nothing is received after the request, a new request is transmitted. Los Angeles County has a statute (which dates from 1944) concerning mounting a "shortwave receiver" in a motor vehicle. Line of sight would be the ultimate in reliability. Propagation. Some repeaters in unusually high locations, such as skyscrapers or mountain tops, can be usable as far out as 75 miles (121 km). For the Colorado VHF/UHF band plans, see the Colorado Council of Amateur Radio Clubs web site. 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). Scanner Frequencies and Radio Frequency Reference Data for Tennessee See PR 91-36 Which is also known as FCC 93-410. Therefore, when using an auroral event as a radio signal reflector, the reflected signal strength and signal intelligibility decreases with increasing transmitting frequency. 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 … Single-sideband (SSB Calling Frequency = 144.200), OSCAR (satellite) APRS Frequency = 144.390 MHz. Amateur radio frequency allocation is done by national telecommunication authorities. Frequency. The channel spacing needs to be at least as wide as the bandwidth of the signal, which allows room for each signal without interfering with the adjacent channel. Stay out of the weak signal and satellite sub-bands. Antennas for repeater work are almost always vertically polarized since 2-meter antennas on cars are usually vertically polarized. FM operation is “channelized”, meaning that specific 2M FM frequencies are identified by the band plan. However, even without repeaters available, the 2-meter band provides reliable crosstown communications throughout smaller towns, making it ideal for emergency communications. 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. Yes, you can operate simplex without a repeater on two-meters FM! Stations in a car or home provide higher power, 25 to 75 watts, and may use a simple vertical antenna mounted on a pole or on the rooftop of a house or a vehicle. The band plan indicates the proper range of frequencies for FM operation but there is more to the story. Globally, the International Telecommunication Union (ITU) oversees how much radio spectrum is set aside for amateur radio transmissions. Individual amateur stations are free to use any frequency within authorized frequency ranges; authorized bands may vary by the class of the station license. Band Plan In areas that use 15-kHz channels, the adjacent channels are 146.535, 146.550, 146.565 MHz, etc. When operating simplex, use a simplex frequency designated by your local band plan. Simple radios for FM repeater operation have become plentiful and inexpensive in recent years. can be used on the band from 144.100 to 148.000 MHz. 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. In Colorado, the channel spacing is 15 kHz, which is a bit tight for our 16 kHz-wide signal. 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. With the exception of sporadic E, directional antennas such as Yagis or log periodic antennas are almost essential to take advantage of signal enhancements. 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. Antennas used for distance work are usually horizontally polarized instead of the vertical polarization customarily used for local contacts. Geographical ... Novice and Technician Plus licensees outside ITU Region 2 may use CW only between 7.050 and 7.075 MHz. W7RNA WebSDR is located in Sedona, AZ, USA (north of Phoenix). Be prepared and able to communicate in case of emergency with the largest selection at eBay.com. Another phenomenon that produces upper atmosphere ionization suitable for 2-meter DXing are the auroras. 151.625: This channel is used by "itinerant" businesses, or those that travel about the country. [8], The Irish Radio Transmitters Society has provided a series of awards for the first successful all-natural, non-bounce contacts on 2 metres between the North American and European continents. 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). There are also frequencies designated for FM simplex. US ... the maximum power output is 1500 watts PEP. Knowing the FCC frequency authorizations is a good start but we need to check a bit further. A two-way conversation can take place over a distance of several hundred miles or more, often using low levels of RF power. 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. 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. 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. 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. FCC Rules As shown in the table, the ARRL 2 Meter amateur band plan supports a wide variety of radio operation. These allocations may only apply to a group of countries. Amateur Radio Ham Radio Repeater in Google Maps. By speeding up Morse code using analog tape or digital modes such as JT6M or FSK441, very short high-speed bursts of digital data can be bounced off the ionized gas trail of meteor showers. 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. FM Operating Ham radio Frequency Chart Graphical Frequency Allocations 2200 and 600 - meter bands General, Advanced and Amateur Extra class licensees are authorized to 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!. Join the fun and adventure on 2 Meter Ham Radio! 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 The ARRL does not list it in their band plan. 146.400, 146.415, 146.430, 146.445, 146.460, 146.475, 146.490, 146.505. Beacons are transmitters that are always on, transmitting a short CW message as a propagation indicator for distant stations. 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. For the HF bands, the frequency privileges depend greatly on the license class of the operator. 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. 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. 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. 2. International Telecommunication Union region (ITU) Regions, http://www.arrl.org/FandES/field/regulations/allocate.html, "Spectrum Forum - Radio Society of Great Britain - Main Site : Radio Society of Great Britain – Main Site", http://www.rsgb.org/getlicence/#foundation, Build a vertical antenna for the 2-meter band, DX-Sherlock's real-time 2m propagation maps, DX-Sherlock's real-time VHF&up propagation ticker, International amateur radio frequency allocations, https://en.wikipedia.org/w/index.php?title=2-meter_band&oldid=977238872, Short description is different from Wikidata, Articles to be expanded from January 2012, Creative Commons Attribution-ShareAlike License. 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. 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). 147.150+ 145.470-PL 127.3 for both. At the very bottom is the CW portion, which includes Earth-Moon-Earth (EME) operation. The use of channels is especially important for repeaters since they don’t easily move around in frequency and are coordinated to minimize interference. Further up the band, we see segments for SSB operation and beacon operation. In these regions, the allocated 2 meter ham radio frequencies are from 144 MHz to 146 MHz. ITU Radio Regulations.. See the appropriate Wiki page for further information. Radio amateurs also use 2 meters for OSCAR (Orbiting Satellite Carrying Amateur Radio) operation, sending signals to a satellite (uplink) or receiving signals from the satellite (downlink). Presentations. It is one of very few ham radio 2 meter frequencies widely coordinated for FM-Simplex-only throughout 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. 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). Across all of North America, the National Simplex Frequency (also referred to as the calling frequency) is 146.52 MHz. 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 Atlantic. Signals in this band travel primarily line-of-sight or slightly further. You might think that the spacing between channels would be 5 kHz, which is the tuning step of most FM radios. The information on this page represents amateur ham radio repeater locations displayed via Google maps. When operating through a repeater, make sure you are tuned to the published repeater frequency with the proper transmit offset. ARRL Band Plan - 2 Meters (144-148 MHz) 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 SSB calling frequency 144.200-144.275 General SSB operation 144.275-144.300 Propagation beacons The typical hand held two meter FM transceiver produces about 5 watts of transmit power. Covers 40, 60 and 75 meter bands. 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. While the ARRL band plan sets the guidelines for band use across the US, VHF band plans are really defined on a statewide or regional basis. Most of this non-FM operation can be easily interfered with by signals from other users. For example, an SSB signal can’t be received on an FM receiver (and vice versa). 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. 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 … 146.400, 146.420, 146.440, 146.460, 146.480, 146.500. Band Plans 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. There is usually another group of FM simplex frequencies in the 147 MHz. On the low end of the band, we see segments for some of the more exotic modes. Matching polarization allows for maximum signal coupling which equates to stronger signals in both directions. Signal enhancements are unusual circumstances in the atmosphere and ionosphere that bend the signal path into an arc that better follows the curve of the Earth, instead of the radio waves traveling in the usual straight line off into space. County. 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. In this example, V/U means VHF/UHF or VHF uplink with UHF downlink. 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). 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). It is widely available to Technician basic ham license (or higher) ham operators in USA. Non - Ham Radio Beacons. 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. This mode is often called burst transmission and can yield communication distances similar to sporadic E as described above. 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. Because of their elevation above the earth, satellites can hear signals from all over the US simultaneously, so they are very susceptible to interference. 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 FCC Rules say that any mode (FM, AM, SSB, CW, etc.) The American Radio Relay League (ARRL) is the national association for amateur radio, connecting hams around the U.S. with news, information and resources. It is widely available to Technician basic ham license (or higher) ham operators in USA. It is one of very few ham radio 2 meter frequencies widely coordinated for FM-Simplex-only throughout USA. Satellites are basically repeater stations in orbit. Repeaters are normally located in high locations such as a tall building or a hill top overlooking expanses of territory. You’ve just purchased your first handheld transceiver and have been chatting with both old and new friends around town on the 2 Meter band. [x] This is not mentioned in the ITU's Table of Frequency Allocations, but individual administrations may make allocations under "Article 4.4". In a future article, we’ll take a look at the 70 cm band. Amateur Radio Ham Radio Repeater in Google Maps. The fine points of the band plan can be a bit confusing. It is widely available to Technician basic ham license (or higher) ham operators in USA. [9] Impressive attempts at the Brendan awards have established contact, but further examination revealed the signal was bounced off the International Space Station.[10]. Two way ducting contacts can have very strong signals and are often made with moderate power, small antennas and other types of modes. However, it is important to note that your local band plan may be different than this. There are also California Penal Code statutes covering similar activities. 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. 2.5 seconds), a person transmitting may hear the end of their own transmission returning. 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. The typical layout of simplex channels is the table below. If you are operating on other bands, be sure to check the appropriate band plan before transmitting. Amateur Radio Frequency List. The data represents the repeaters frequency, offset, CTCSS, PL and notes such as if it supports IRLP, Echolink, autopatch, etc. These prohibitions and/or exemptions vary from state to state. Hack Green, England, now a working museum. Amateurs know what mode is in use via published internet schedules. Completion of contacts using these weak signal modes involves the exchange of signal level reports and location by grid square which is known as the Maidenhead Locator System. Considerate Operator's Frequency Guide Fun with Satellites presentation at SEA-PAC June 4, 2016 These radios usually tune the entire 2M band from 144 MHz to 148 MHz in 5 kHz steps. A good source is your local frequency coordination body, which is listed on the ARRL web site. Sporadic E is a rare and completely random propagation phenomenon lasting anywhere from a matter of minutes to several hours. For repeaters that require a CTCSS tone for repeater access, you will have to set the proper tone frequency on transmit. 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. One of these modes is JT65 which is a digital mode. 2 145.590 ERC Ogden Area (LDS Simplex) 32 TM-D710A Matching Channel # & Frequency 3 146.480 Box Elder County (ARES Simplex) 3 4 145.290 123 Brigham City (Linked to 145.430, 448.300 & 147.220) 2 Brigham Emergency Radio Frequency: 1610 AM 5 145.430 123 GSARC (ATK - Linked to 448.300, 145.290 & 147.220) 1 The 2 meter band is also used in conjunction with the 70-centimeter band, or the 10-meter band and various microwave bands via orbiting amateur radio satellites. Covers Ham HF, 11 meters, CB, SSB, VHF FM, 2 meters, 10 meters, UHF walkie talkies, handy … The OSCAR segments don’t specify a particular modulation type since CW, SSB and FM are all used for OSCAR operation. This is a phenomenon whereby radio signals are reflected back towards Earth by highly ionized segments of the ionosphere which can facilitate contacts in excess of 1,000 miles (1,600 km) with very strong signals received by both parties.
