146.745 MHZ split down 146.2 PL. A two-way conversation can take place over a distance of several hundred miles or more, often using low levels of RF power. 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. This mode is often called burst transmission and can yield communication distances similar to sporadic E as described above. On VHF frequencies such as 2-meters, antenna height greatly influences how far one can talk. US Amateur Radio Frequency Allocations. The typical layout of simplex channels is the table below. New Jersey. The band plan indicates the proper range of frequencies for FM operation but there is more to the story. 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. While arrest rarely happens, the statute is still on the books. The fine points of the band plan can be a bit confusing. Another phenomenon that produces upper atmosphere ionization suitable for 2-meter DXing are the auroras. On the low end of the band, we see segments for some of the more exotic modes. The ARRL Letter, Vol. 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. 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. Because of their elevation above the earth, satellites can hear signals from all over the US simultaneously, so they are very susceptible to interference. There are also frequencies designated for FM simplex. County. 20, No. 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). 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!. 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 … This is particularly a problem with FM receivers, which won’t even notice low-level CW and SSB signals. Cape May. It covers 160 m to 17 meter … We’ve only covered the 2 Meter band in this article. 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. The data represents the repeaters frequency, offset, CTCSS, PL and notes such as if it supports IRLP, Echolink, autopatch, etc. 2 meters is much more than just your handheld radio and a repeater. Below the calling frequency are 146.505, 146.490, 146.475 MHz and on. Antennas for repeater work are almost always vertically polarized since 2-meter antennas on cars are usually vertically polarized. Beacons are transmitters that are always on, transmitting a short CW message as a propagation indicator for distant stations. The Radio Regulations of the International Telecommunication Union allow amateur radio operations in the frequency range from 144 to 148 MHz. 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 2-meter amateur radio band is a portion of the VHF radio spectrum, comprising 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)[1] and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and Russia). The FCC has restricted 144.0 to 144.100 MHz to CW operation only. In some parts of North America, non-standard repeater offsets may be used, which will be indicated in the repeater directory. Los Angeles County has a statute (which dates from 1944) concerning mounting a "shortwave receiver" in a motor vehicle. These are commonly called the "WARC bands". The ARRL does not list it in their band plan. 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. FM Operating Individual amateur stations are free to use any frequency within authorized frequency ranges; authorized bands may vary by the class of the station license. Matching polarization allows for maximum signal coupling which equates to stronger signals in both directions. For the Colorado VHF/UHF band plans, see the Colorado Council of Amateur Radio Clubs web site. 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. 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. 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). 146.400, 146.420, 146.440, 146.460, 146.480, 146.500. This is known as cross band repeating. [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). It is widely available to Technician basic ham license (or higher) ham operators in USA. Thus, it makes sense to have a band plan that divides the band up into segments for each type of operation. Further up the band, we see segments for SSB operation and beacon 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. Above 50 MHz, the frequency allocations are the same for Technician licenses and higher. 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. Two way ducting contacts can have very strong signals and are often made with moderate power, small antennas and other types of modes. Propagation. Graphical Chart ... Novice/Technicians are limited to 200 watts PEP on HF bands. You might think that the spacing between channels would be 5 kHz, which is the tuning step of most FM radios. It is one of very few ham radio 2 meter frequencies widely coordinated for FM-Simplex-only throughout USA. Large portions of the band are dedicated to FM operation, consistent with the popularity of the FM mode. 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. Contains a table showing standard ham radio 2-meter repeater input frequency offsets from output frequencies. Sporadic E is a rare and completely random propagation phenomenon lasting anywhere from a matter of minutes to several hours. 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). 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. 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 (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 Repeaters are normally located in high locations such as a tall building or a hill top overlooking expanses of territory.

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. 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. When operating through a repeater, make sure you are tuned to the published repeater frequency with the proper transmit offset. There are also California Penal Code statutes covering similar activities. These radios usually tune the entire 2M band from 144 MHz to 148 MHz in 5 kHz steps. [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 American Radio Relay League (ARRL) is the national association for amateur radio, connecting hams around the U.S. with news, information and resources. Great deals on 2 Meters Ham & Amateur Radio Transceivers. [x] This is not mentioned in the ITU's Table of Frequency Allocations, but individual administrations may make allocations under "Article 4.4". Atlantic. 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. 2.5 seconds), a person transmitting may hear the end of their own transmission returning. 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). This doesn’t work because a typical FM signal occupies a bandwidth that is about 16 kHz wide. 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. As shown in the table, the ARRL 2 Meter amateur band plan supports a wide variety of radio operation. 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. Signals in this band travel primarily line-of-sight or slightly further. It is one of very few ham radio 2 meter frequencies widely coordinated for FM-Simplex-only throughout USA. "Beam antennas" provide substantial increase in signal directivity over ordinary dipole or vertical antennas. Fun with Satellites presentation at SEA-PAC June 4, 2016 Fast & Free shipping on many items! Camden . 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. Join the fun and adventure on 2 Meter Ham Radio! The information on this page represents amateur ham radio repeater locations displayed via Google maps. If you’re just starting as a newbie ham, a 100 mile range will already sound good. For repeaters that require a CTCSS tone for repeater access, you will have to set the proper tone frequency on transmit. We need to use our authorized frequencies wisely by sharing the band with other users and avoiding unnecessary interference. [9] Impressive attempts at the Brendan awards have established contact, but further examination revealed the signal was bounced off the International Space Station.[10]. Deze lijst is voor het laatst herzien op 24-12-2018 en gebaseerd op data van het Agentschap Telecom. For the HF bands, the frequency privileges depend greatly on the license class of the operator. Stoke-on-Trent ARS HF WebSdr is located at the Nantwich Secret Nuclear Bunker, formerly R.A.F. 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. 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. 2 meters (a mix of 20 kHz and 15 kHz channel spacing) 145.2 – 145.5 146.61 – 146.97. 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. 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 This means it is best to find the specific band plan for your region. 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. 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. It is usual for them to be heard at distances far beyond line of sight on a daily basis without help from signal enhancements. 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. The data represents the repeaters frequency, offset, CTCSS, PL and notes such as if it supports IRLP, Echolink, autopatch, etc. To communicate over the longest distances, hams use moon bounce. Amateur Radio Ham Radio Repeater in Google Maps. Single-sideband (SSB Calling Frequency = 144.200), OSCAR (satellite) APRS Frequency = 144.390 MHz. 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. The use of channels is especially important for repeaters since they don’t easily move around in frequency and are coordinated to minimize interference. Geographical power restrictions apply to the 630 meter, 70 centimeter, 33 centimeter and 23 centimeter bands. Such stations are able to communicate 100–300 miles (160–480 km) consistently. 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. Satellites are basically repeater stations in orbit. Summary 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. 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). This continues until a reply is received to confirm the contact or until no contact can be made and no new requests are sent. 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. 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. Considerate Operator's Frequency Guide 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. 147.00 – 147.39 – 600 kHz – 600 kHz + 600 kHz. 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. 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 The satellite radio signals are classified into two groups: voice and data tranmissions. Antennas used for distance work are usually horizontally polarized instead of the vertical polarization customarily used for local contacts. At that height amateurs can expect reception distances of up to around 3,000 miles (4,800 km). [w] HF allocation created at the 1979 World Administrative Radio Conference. Amateur radio frequency allocation is done by national telecommunication authorities. This page was last edited on 7 September 2020, at 18:29. In these regions, the allocated 2 meter ham radio frequencies are from 144 MHz to 146 MHz. At the very bottom is the CW portion, which includes Earth-Moon-Earth (EME) operation. When operating simplex, use a simplex frequency designated by your local band plan. The OSCAR segments don’t specify a particular modulation type since CW, SSB and FM are all used for OSCAR operation. Amateur Radio Ham Radio Repeater in Google Maps. De volgende (analoge) repeaters zijn te vinden op de 2 meter band tussen 144 en 146 MHz. 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 In Colorado, the channel spacing is 15 kHz, which is a bit tight for our 16 kHz-wide signal. In particular, the 2m band extends from 144 MHz to 148 MHz. However, a few simple guidelines can help, especially if you are operating only FM. Sharing spectrum with other services a ham radio reality. FM operation is “channelized”, meaning that specific 2M FM frequencies are identified by the band plan. See PR 91-36 Which is also known as FCC 93-410. Due to the delay of the signal traveling to the moon and back (travel time approx. The ranges given here are *estimates* based on *smooth earth*, and in the interest of not misleading anyone I … EME operators communicate by bouncing their signals off the moon. Best Ham Radio Frequencies for Long Distance Communication. 2-meter Simplex FM Frequencies by joel Sampson / N5LXI. Some repeaters in unusually high locations, such as skyscrapers or mountain tops, can be usable as far out as 75 miles (121 km). can be used on the band from 144.100 to 148.000 MHz. Typical reliable repeater range is about 25 miles (40 km). The first thing we need to know are the frequencies that the FCC has authorized for our particular license class. This may be a challenge to find the right information, but try searching the web for “2-meter band plan” and your state. It is one of very few ham radio 2 meter frequencies widely coordinated for FM-Simplex-only throughout USA. Covers VLF, 160, 80, 40, 30, 20 and 2 meters. Amateur Radio Frequency List. For example, an SSB signal can’t be received on an FM receiver (and vice versa). 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). 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. 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 … In many instances 6 meter voice modes are readable but with varying degrees of difficulty when reflected off an aurora. Burlington. 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. Radio Distance Range Comparison of Ham CB FRS MURS GMRS Radios. Stay out of the weak signal and satellite sub-bands. These allocations may only apply to a group of countries. W7RNA WebSDR is located in Sedona, AZ, USA (north of Phoenix). 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. Amateurs know what mode is in use via published internet schedules. All classes are limited to 200 watts PEP in the 80, 40, and 15 meter Novice/Technician Plus subbands. These prohibitions and/or exemptions vary from state to state. In other parts of the country, a 20-kHz spacing has been adopted to provide for more separation between channels. This popularity, the compact size of needed radios and antennas, and this band's ability to provide easy reliable local communications also means that it is also the most used band for local emergency communications efforts, such as providing communications between Red Cross shelters and local authorities. With the exception of sporadic E, directional antennas such as Yagis or log periodic antennas are almost essential to take advantage of signal enhancements. Circuses, exhibitions, trade shows, and sports teams are some of the users you can hear. 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 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). FM voice simplex and repeater operation should only occur in the designated band segments for your area. Yes, you can operate simplex without a repeater on two-meters FM! Be prepared and able to communicate in case of emergency with the largest selection at eBay.com. Knowing the FCC frequency authorizations is a good start but we need to check a bit further. FCC Rules Notice that these segments are positioned 600 kHz apart consistent with the standard 2M repeater offset. 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 Band Plan 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. In a future article, we’ll take a look at the 70 cm band. It is widely available to Technician basic ham license (or higher) ham operators in USA. [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. In areas that use 15-kHz channels, the adjacent channels are 146.535, 146.550, 146.565 MHz, etc. 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. There are a few amateur satellites that have very high elliptical orbits. 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. If you are operating on other bands, be sure to check the appropriate band plan before transmitting. The telecommunications that are conducted in the 2 meter band is usually conducted only within about 100 miles. Similarly, an operator chatting across town on 2M could interfere with a satellite hundreds of miles away and not know it. In this example, V/U means VHF/UHF or VHF uplink with UHF downlink. Therefore, when using an auroral event as a radio signal reflector, the reflected signal strength and signal intelligibility decreases with increasing transmitting frequency. 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. 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. Simple radios for FM repeater operation have become plentiful and inexpensive in recent years. 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. However, even without repeaters available, the 2-meter band provides reliable crosstown communications throughout smaller towns, making it ideal for emergency communications. Because it is local and reliable, and because the licensing requirements to transmit on the 2-meter band are easy to meet in many parts of the world,[4] this band is one of the most popular non-HF ham bands. Often, these modulation techniques are incompatible since a signal of one type can’t be received by a radio set to another modulation type. 151.625: This channel is used by "itinerant" businesses, or those that travel about the country. 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. Scanner Frequencies and Radio Frequency Reference Data for Tennessee 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. 146.400, 146.415, 146.430, 146.445, 146.460, 146.475, 146.490, 146.505. The typical hand held two meter FM transceiver produces about 5 watts of transmit power. Several regional frequency coordinators recognize 223.5000 as the national 1.25m band FM simplex calling frequency. Ham radio Frequency Chart Graphical Frequency Allocations 2200 and 600 - meter bands General, Advanced and Amateur Extra class licensees are authorized to moving upward. There is usually another group of FM simplex frequencies in the 147 MHz. Most of this non-FM operation can be easily interfered with by signals from other users. 2 Meter Band Plan 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.
