Introduction
Radios have obvious advantages in providing real-time, simple, and reliable communication, making them an indispensable tool in many activities and emergencies. Since FRS and PMR radios do not require a license, they are the most common type and frequently used in daily life. In this guide, we will explore the features, regulations, and practical tips of FRS and PMR radios.
FRS(Family Radio Service)
FRS is a widely used radio service in the United States and Canada. It operates on UHF (Ultra High Frequency) radio bands and provides short-range communication for personal and family use. Here are some key points about FRS:
Frequency Range: FRS radios typically operate within the range of 462.5625 MHz to 462.725 MHz, with a total of 22 channels available.
Power Output: FRS radios have a maximum power output of 2 watts, ensuring a limited range of communication, usually up to 1-2 miles.
Features: FRS radios often include features like channel scanning, privacy codes, and weather channels to enhance communication and safety.
PMR(Private Mobile Radio)
PMR is a radio service popular in Europe, particularly in countries like Germany and the United Kingdom. Here are some key points about PMR:
Frequency Range: PMR radios operate on different frequency bands depending on the country. In Europe, PMR446 radios, which is most common, use the 446.00625 MHz to 446.19375 MHz frequency range, with 8-16 channels available.
Power Output: PMR446 radios have a maximum power output of 0.5 watts.
Features: PMR radios often include features like channel scan, CTCSS/DCS codes for privacy, and hands-free operation for convenience.
Practical tips
Using FRS or PMR radios is very simple. It only takes two steps: turn on the radio and tune to the same channel, and the two walkie-talkies can communicate. To use those radios more conveniently, it's helpful to understand two common function settings: VOX and CTCSS/DCS.
VOX(Voice-Operated Exchange)
The VOX function monitors the user's voice through a microphone or built-in microphone. When it detects that the user starts talking, VOX automatically activates the send function of the intercom, allowing the user to speak. When the user stops talking for a period of time, VOX automatically turns off the send function.
Note:Since VOX is activated by sound, it can be mistakenly triggered in a noisy environment. In this case, if the VOX sensitivity is set too high, it may cause noise or interference during transmission. Therefore, users should adjust the VOX settings based on actual conditions and needs.
CTCSS/DCS
CTCSS (Continuous Tone-Coded Squelch System) is a continuous tone-coded squelch system that filters out extraneous signals by adding specific tones between transmission and reception. DCS(Digital-Coded Squelch) is a digital-coded squelch system that is similar to CTCSS but uses digital codes instead of tones.
The CTCSS/DCS function can be used to enhance the privacy and security of walkie-talkie communications. By setting a specific CTCSS tone or DCS code, users can communicate on the channel with other walkie-talkies using the same settings, without interference from other channels. This is very useful for communicating in a crowded frequency environment or when the communication content needs to be protected.
Note: Both parties must be tuned to the same channel and CTCSS tone or DCS code; otherwise, the walkie-talkie will not be able to correctly decode the other party's signal.
