How to listen to the radio with a walkie-talkie: Function analysis and operation guide
As a common communication tool, walkie-talkies are not only used for two-way calls, but some models also support the function of listening to radio broadcasts. This article will introduce in detail the method of listening to radio broadcasts, applicable models and precautions, and combine it with recent hot topics to help users make better use of this function.
1. The principle of listening to radio through walkie-talkie
Some multifunctional walkie-talkies have built-in FM radio modules, which can receive local FM broadcast signals by switching modes. The following are common brands and models of walkie-talkies that support broadcast functions:
| brand | Models that support broadcasting | frequency range |
|---|---|---|
| BAOFENG | UV-5R, UV-82 | FM 76-108MHz |
| Motorola | T800, T600 | FM 87.5-108MHz |
| QUANSHENG | TG-UV2 | FM 88-108MHz |
2. Detailed explanation of operating steps
Taking Baofeng UV-5R as an example, the specific operation process is as follows:
| steps | Operation |
|---|---|
| 1 | Long press the "VFO/MR" key to enter frequency mode |
| 2 | Press the "BAND" key to switch to the FM radio band |
| 3 | Turn the knob to search for channels or enter the frequency manually |
| 4 | Press the "PTT" side button to confirm listening |
3. Related topics of recent hot topics
Combined with the hot spots on the entire network in the past 10 days, the walkie-talkie broadcast function has attracted attention in the following scenarios:
| hot events | Related applications |
|---|---|
| Emergency response to heavy rain disasters in many places | Receive weather warnings via radio |
| Outdoor hiking craze | Mountain FM radio as backup information source |
| radio amateur activities | Modified walkie-talkies to expand broadcast reception capabilities |
4. Precautions
1.legal restrictions: Some countries prohibit the modification of walkie-talkies with broadcast reception functions. Please confirm local regulations before use.
2.signal quality: The antenna performance of the built-in FM module is usually weaker than that of professional radios
3.Power consumption: Continuously listening to the radio will speed up battery consumption. A backup power supply is recommended.
4.Functional differences: Professional walkie-talkies (such as Motorola XIR series) usually do not include broadcast functions
5. Comparison of technical parameters
| parameters | Walkie talkie FM radio | professional radio |
|---|---|---|
| Sensitivity | 3-5μV | 1-2μV |
| Frequency response range | 80Hz-8KHz | 20Hz-20KHz |
| Continuous use time | 4-6 hours | 15-30 hours |
6. Recommendation of alternatives
If the walkie-talkie does not have a broadcast function, the following combination solutions can be considered:
1.External sound module: Connected through 3.5mm interface (requires the walkie-talkie to support audio input)
2.Cell Phone Emergency Plan: Download the Internet radio APP + power bank combination
3.Professional equipment: Desheng and other brands of emergency radios have intercom functions
By rationally utilizing the broadcast function of walkie-talkies, users can obtain more information channels in emergency communications, outdoor activities and other scenarios. It is recommended to test device performance regularly and pay attention to local FM broadcast frequency updates.
