Join the fun and adventure on 2 Meter Ham Radio! 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, this band is one of the most popular non-HF 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. It is one of very few ham radio 2 meter frequencies widely coordinated for FM-Simplex-only throughout USA.  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). Single-sideband (SSB Calling Frequency = 144.200), OSCAR (satellite) APRS Frequency = 144.390 MHz. Burlington. 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. Band Plans 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. Further up the band, we see segments for SSB operation and beacon operation. De volgende (analoge) repeaters zijn te vinden op de 2 meter band tussen 144 en 146 MHz. 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 first thing we need to know are the frequencies that the FCC has authorized for our particular license class. Non - Ham Radio Beacons. 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. 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). This mode is often called burst transmission and can yield communication distances similar to sporadic E as described above. The FCC Rules say that any mode (FM, AM, SSB, CW, etc.) 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. Scanner Frequencies and Radio Frequency Reference Data for Tennessee This page was last edited on 7 September 2020, at 18:29. In this example, V/U means VHF/UHF or VHF uplink with UHF downlink. W7RNA WebSDR is located in Sedona, AZ, USA (north of Phoenix). For repeaters that require a CTCSS tone for repeater access, you will have to set the proper tone frequency on transmit. 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 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. [y] This includes a currently active footnote allocation mentioned in the ITU's Table of Frequency Allocations. 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 Repeaters are normally located in high locations such as a tall building or a hill top overlooking expanses of territory. The satellite radio signals are classified into two groups: voice and data tranmissions. [x] This is not mentioned in the ITU's Table of Frequency Allocations, but individual administrations may make allocations under "Article 4.4". Beacons are transmitters that are always on, transmitting a short CW message as a propagation indicator for distant stations. 2.5 seconds), a person transmitting may hear the end of their own transmission returning. In Colorado, the channel spacing is 15 kHz, which is a bit tight for our 16 kHz-wide signal. This is known as cross band repeating. 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!. The typical layout of simplex channels is the table below. At the very bottom is the CW portion, which includes Earth-Moon-Earth (EME) operation. (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 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). 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).  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. Satellites are basically repeater stations in orbit. The information on this page represents amateur ham radio repeater locations displayed via Google maps. However, it is important to note that your local band plan may be different than this. All classes are limited to 200 watts PEP in the 80, 40, and 15 meter Novice/Technician Plus subbands. 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. Several regional frequency coordinators recognize 223.5000 as the national 1.25m band FM simplex calling frequency. can be used on the band from 144.100 to 148.000 MHz. Contains a table showing standard ham radio 2-meter repeater input frequency offsets from output frequencies. Typically on 2 meter, the “offset” is 600 kilohertz. 146.400, 146.415, 146.430, 146.445, 146.460, 146.475, 146.490, 146.505. 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. 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. A good source is your local frequency coordination body, which is listed on the ARRL web site. 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. 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. If you’re just starting as a newbie ham, a 100 mile range will already sound good. It is one of very few ham radio 2 meter frequencies widely coordinated for FM-Simplex-only throughout USA. 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. 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. A two-way conversation can take place over a distance of several hundred miles or more, often using low levels of RF power. One of these modes is JT65 which is a digital mode. Simple radios for FM repeater operation have become plentiful and inexpensive in recent years. 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 Circuses, exhibitions, trade shows, and sports teams are some of the users you can hear. 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). The ARRL Letter, Vol. Be prepared and able to communicate in case of emergency with the largest selection at eBay.com. Camden . 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. Amateur Radio Ham Radio Repeater in Google Maps. There are also frequencies designated for FM simplex. 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. 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. 146.400, 146.420, 146.440, 146.460, 146.480, 146.500. For the HF bands, the frequency privileges depend greatly on the license class of the operator. 2-meter Simplex FM Frequencies by joel Sampson / N5LXI. 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). Amateur Radio Frequency List. The ranges given here are *estimates* based on *smooth earth*, and in the interest of not misleading anyone I … Because of their elevation above the earth, satellites can hear signals from all over the US simultaneously, so they are very susceptible to interference. 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. The American Radio Relay League (ARRL) is the national association for amateur radio, connecting hams around the U.S. with news, information and resources. There is usually another group of FM simplex frequencies in the 147 MHz.  Impressive attempts at the Brendan awards have established contact, but further examination revealed the signal was bounced off the International Space Station.. 151.625: This channel is used by "itinerant" businesses, or those that travel about the country. There are many different frequencies to choose from, so how do you find an appropriate frequency to use? 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 … Stoke-on-Trent ARS HF WebSdr is located at the Nantwich Secret Nuclear Bunker, formerly R.A.F. Signals in this band travel primarily line-of-sight or slightly further. 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). It is widely available to Technician basic ham license (or higher) ham operators in USA. Line of sight would be the ultimate in reliability. Due to the delay of the signal traveling to the moon and back (travel time approx. 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. 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. Thus, it makes sense to have a band plan that divides the band up into segments for each type of operation. However, a few simple guidelines can help, especially if you are operating only FM. 2 Meter Band Plan 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. Another phenomenon that produces upper atmosphere ionization suitable for 2-meter DXing are the auroras. Great deals on 2 Meters Ham & Amateur Radio Transceivers. Deze lijst is voor het laatst herzien op 24-12-2018 en gebaseerd op data van het Agentschap Telecom. EME operators communicate by bouncing their signals off the moon. In many instances 6 meter voice modes are readable but with varying degrees of difficulty when reflected off an aurora. Globally, the International Telecommunication Union (ITU) oversees how much radio spectrum is set aside for amateur radio transmissions. moving upward. Atlantic. Amateur radio operators use a variety of modulation techniques to carry out communications. 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. While arrest rarely happens, the statute is still on the books. Therefore, when using an auroral event as a radio signal reflector, the reflected signal strength and signal intelligibility decreases with increasing transmitting frequency. It is widely available to Technician basic ham license (or higher) ham operators in USA. FM Operating 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. 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). See PR 91-36 Which is also known as FCC 93-410. 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. 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. 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. The OSCAR segments don’t specify a particular modulation type since CW, SSB and FM are all used for OSCAR operation. ITU Radio Regulations.. See the appropriate Wiki page for further information. If nothing is received after the request, a new request is transmitted. Band Plan There are also California Penal Code statutes covering similar activities. Knowing the FCC frequency authorizations is a good start but we need to check a bit further. 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. Yes, you can operate simplex without a repeater on two-meters FM! Another form of VHF propagation is called Sporadic E propagation. However, even without repeaters available, the 2-meter band provides reliable crosstown communications throughout smaller towns, making it ideal for emergency communications. 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. Some repeaters in unusually high locations, such as skyscrapers or mountain tops, can be usable as far out as 75 miles (121 km). Such stations are able to communicate 100–300 miles (160–480 km) consistently. Sporadic E is a rare and completely random propagation phenomenon lasting anywhere from a matter of minutes to several hours. Notice that these segments are positioned 600 kHz apart consistent with the standard 2M repeater offset. In other parts of the country, a 20-kHz spacing has been adopted to provide for more separation between channels. 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 This is particularly a problem with FM receivers, which won’t even notice low-level CW and SSB signals. In areas that use 15-kHz channels, the adjacent channels are 146.535, 146.550, 146.565 MHz, etc. Geographical ... Novice and Technician Plus licensees outside ITU Region 2 may use CW only between 7.050 and 7.075 MHz. US Amateur Radio Frequency Allocations. 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. Sharing spectrum with other services a ham radio reality. These prohibitions and/or exemptions vary from state to state. At that height amateurs can expect reception distances of up to around 3,000 miles (4,800 km). "Beam antennas" provide substantial increase in signal directivity over ordinary dipole or vertical antennas. Fast & Free shipping on many items! This means it is best to find the specific band plan for your region. 147.150+ 145.470-PL 127.3 for both. Los Angeles County has a statute (which dates from 1944) concerning mounting a "shortwave receiver" in a motor vehicle. The ARRL does not list it in their band plan. US ... the maximum power output is 1500 watts PEP. The data represents the repeaters frequency, offset, CTCSS, PL and notes such as if it supports IRLP, Echolink, autopatch, etc. Two way ducting contacts can have very strong signals and are often made with moderate power, small antennas and other types of modes. For example, an SSB signal can’t be received on an FM receiver (and vice versa). CW signals returning from an auroral reflection have no distinct sound or tone but simply sound like a swishing or whooshing noise. 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 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. These radios usually tune the entire 2M band from 144 MHz to 148 MHz in 5 kHz steps. Typical reliable repeater range is about 25 miles (40 km). 2 meters is much more than just your handheld radio and a repeater. 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. Amateur Radio Ham Radio Repeater in Google Maps. This doesn’t work because a typical FM signal occupies a bandwidth that is about 16 kHz wide. Large portions of the band are dedicated to FM operation, consistent with the popularity of the FM mode. County. 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 … 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.
