General Facts About Radio Frequncies

The radio spectrum is the part of the electromagnetic spectrum with frequencies from 30 Hz to 300 GHz. Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication. To prevent interference between different users, the generation and transmission of radio waves is strictly regulated by national laws, coordinated by an international body, the International Telecommunication Union.

Different parts of the radio spectrum are allocated by the ITU for different radio transmission technologies and applications; some 40 radiocommunication services are defined in the ITU's Radio Regulations (RR). In some cases, parts of the radio spectrum are sold or licensed to operators of private radio transmission services (for example, cellular telephone operators or broadcast television stations). Ranges of allocated frequencies are often referred to by their provisioned use (for example, cellular spectrum or television spectrum). Because it is a fixed resource which is in demand by an increasing number of users, the radio spectrum has become increasingly congested in recent decades, and the need to utilize it more effectively is driving modern telecommunications innovations such as trunked radio systems, spread spectrum, ultra-wideband, frequency reuse, dynamic spectrum management, frequency pooling, and cognitive radio.

BASICS

As a matter of convention, the ITU divides the radio spectrum into 12 bands, each beginning at a wavelength which is a power of ten (10n) metres, with corresponding frequency of 3×108−n hertz, and each covering a decade of frequency or wavelength. Each of these bands has a traditional name. For example, the term high frequency (HF) designates the wavelength range from 100 to 10 metres, corresponding to a frequency range of 3 MHz to 30 MHz. This is just a naming convention and is not related to allocation; the ITU further divides each band into subbands allocated to different uses. Above 300 GHz, the absorption of electromagnetic radiation by Earth's atmosphere is so great that the atmosphere is effectively opaque, until it becomes transparent again in the near-infrared and optical window frequency ranges.

These ITU radio bands are defined in the ITU Radio Regulations. Article 2, provision No. 2.1 states that "the radio spectrum shall be subdivided into nine frequency bands, which shall be designated by progressive whole numbers in accordance with the following table.

The table originated with a recommendation of the IVth CCIR meeting, held in Bucharest in 1937, and was approved by the International Radio Conference held at Atlantic City, NJ in 1947. The idea to give each band a number, in which the number is the logarithm of the approximate geometric mean of the upper and lower band limits in Hz, originated with B.C. Fleming-Williams, who suggested it in a letter to the editor of Wireless Engineer in 1942. (For example, the approximate geometric mean of Band 7 is 10 MHz, or 107 Hz)

Family Radio Service [FRS]

The Family Radio Service (FRS) is an improved walkie-talkie radio system authorized in the United States since 1996. This personal radio service uses channelized frequencies around 462 and 467 MHz in the ultra high frequency (UHF) band. It does not suffer the interference effects found on citizens' band (CB) at 27 MHz, or the 49 MHz band also used by cordless telephones, toys (aside from ChatNow, which used FRS), and baby monitors. FRS uses frequency modulation (FM) instead of amplitude modulation (AM). Since the UHF band has different radio propagation characteristics, short-range use of FRS may be more predictable than the more powerful license-free radios operating in the HF CB band

Initially proposed by RadioShack in 1994 for use by families, FRS has also seen significant adoption by business interests, as an unlicensed, low-cost alternative to the business band. New rules issued by the FCC in May 2017 clarify and simplify the overlap between FRS and GMRS radio services.

After 18 May 2017, FRS radios are limited to 2 Watts on channel 1-7 and channels 15–22. Previously, FRS radios were limited to 500 milliwatts. All 22 Channels are shared with the General Mobile Radio Service (GMRS).

There are rules governing the frequencies within this group. [ie.. channels 1-7 and 8-22]. Please read up on those rules prior to getting or using a radio.

Types of Ham Radio Certifications

FCC Restructuring: In December 1999, after a lengthy review of the Amateur Radio licensing system, the FCC began issuing major changes. In April 2000, the number of license classes dropped from six to the current three. In addition, in February 2007, the FCC discontinued requiring Morse code proficiency tests. The FCC issued these new regulations to streamline the licensing system and bring the Amateur Radio service into the digital age. While the new license system might not make it easier to get into Amateur Radio, licensed operators can move from the beginner to expert level more quickly.

General Info: There are three types of licenses for ham radio operators are being granted today: Technician, General, and Amateur Extra. By taking progressively more challenging exams, you gain access to more frequencies and operating privileges.

After you pass a specific test level, called an element, you have permanent credit for it as long as you keep your license renewed. This system allows you to progress at your own pace. Your license is good for ten years, and you can renew it without taking an exam.

License Class Privleges Notes
Technician All amateur privileges above 50 MHz; limited CW, Phone, and Data privileges below 30 MHz
General Technician privileges plus most amateur HF privileges
Amateur Extra All amateur privileges Small exclusive sub-bands are added on 80, 40, 20, and 15 meters.

Nearly every ham starts with a Technician class license, also known as a Tech license. A Technician licensee is allowed access to all ham bands with frequencies of 50 MHz or higher. These privileges include operation at the maximum legal power limit and using all types of communications.

Tech licensees may also transmit using voice on part of the 10 meter band and Morse code on some of the HF bands below 30 MHz. The test for this license consists of 35 multiple-choice questions on regulations and technical radio topics. You have to get 26 or more correct to pass.

Morse code still makes up a great deal of amateur operations, from casual ragchewing to passing messages, participating in contests, and providing emergency operations. Its efficient use of transmitted power and spectrum space, as well as its innate musicality and rhythm, make it very popular with hams. Also, it’s easy and fun to use.

General Class: After earning the entry-level Technician license, many hams immediately start getting ready to upgrade to a General class license. When you obtain a General class license, you’ve reached a great milestone. General class licensees have full privileges on nearly all amateur frequencies, with only small portions of some HF bands remaining off limits.

The General class exam, which includes 35 questions (you have to get 26 right to pass), covers many of the same topics as the Technician exam, but in more detail. The exam introduces some new topics that an experienced ham is expected to understand.

Amateur Extra Class: General class licensees still can’t access everything; the lowest segments of several HF bands are for Amateur Extra class licensees only. These segments are where the expert Morse code operators hang out and are considered to be prime operating territory. If you become interested in contesting, contacting rare foreign stations (DXing), or just having access to these choice frequencies, you want to get your Amateur Extra license — the top level.

The Amateur Extra exam consists of 50 multiple-choice questions, 37 of which you must answer correctly to pass. The exam covers additional rules and regulations associated with sophisticated operating and several advanced technical topics. Hams who pass the Amateur Extra exam consider their license to be a real achievement.

Grandfathered Classes: The amateur service licensing rules have changed over the years, reducing the number of license classes. Hams who hold licenses in deleted classes may renew those licenses indefinitely, but no new licenses for those classes are being issued. Two grandfathered license classes remain:

  • Novice: The Novice license was introduced in 1951 with a simple 20-question test and 5-words-per-minute code exam. A ham with a General class (or higher) license administered the exam. Originally, the license was good for a single year, at which point the Novice upgraded or had to get off the air. These days, the Novice license, like other licenses, has a ten-year term and is renewable. Novices are restricted to segments of the 3.5, 7, 21, 28, 222, and 1296 MHz amateur bands.
  • Advanced: Advanced class licensees passed a written exam midway in difficulty between those for the General and Amateur Extra classes. They received frequency privileges between those of General and Amateur Extra licensees.

Some Information Regarding Public Service Channels

So you want to listen to police, fire and ems. Where to begin?

There are so many channels, frequencies and bands that I'm not sure where to begin. Each city, township, county and agency has their own.

I live in Bucks County PA, so I'll use this as an example. In the old days all communications were done in the bands from 40Mhz to 155Mhz. This included Police, Fire and EMS. The frequencies had pros and cons back then:

  1. Radios were cheaper then todays
  2. Easier to use
  3. Less restrictive on crosstalk
  4. Fire and EMS were on "LOW" band [46.00MHz]
  5. Police were on "VHF" [High" band [155.00Mhz]
  1. Needed a license to operate [Both the station and county]

Public Safety [cont'd]

That was then. Today with all the scanners out there the police wanted privacy. It isn't against federal law to listen to the channels [in some states it is] you can't discuss what you hear on them with anyone not present at the time you hear it.

With that in mind, public safety departments decided it was time for a change. They wanted "PRIVACY". Several companies began development on "SECURE" radio systems called "Trunked" systems. I'm not going to explain how they work. You can look them up online. They wanted encryption and othe features included. Now Bucks County is using project 25 - phase II - allegedly starting on phase III.

Repeater systems are set up throughout the county transmitting the new frequencies on the lower band as before. This is mainly due to the fact that scanners needed to pick up the new truncked systems and decode them cost around 700-800 dollars. This makes it easier for fireman and others to respond.

The county is broken down into zones for fire, ems and zones for police. See the chart below for breakdown.

NOTE: I have tried to do my best with the above listing. As I live in the south part of the county; police zone 1 - I know that and part of the central area best. Some of the stations listed had no township or Boro listed with them and after doing some research I placed them as they're shown. If I made any mistakes please email me [contact form] and I will make the corrections. This includes police, fire and ems. Thank You.
