Walkie Talkie FAQ

Ans: yes, the Indian law permits license free walkie talkie in the 27 MHz band but this frequency band interferes with other wireless products.
Ans: These radios are not authorized by the Indian Ministry of Telecom for the following reason – they work on 400 MHz band and not the licensed band of 350 MHz. In India, the 400 MHz band is used by Para Military Forces And The walkie talkies offered on the internet do not carry any warranty. Moreover, spare battery, antenna or chargers are not available separately. These are basically use and throw models.
Ans: No. VHF radios operate in the VHF 136-174 MHz range and UHF radios operate in the UHF 400-470 MHz and 350-390 MHz range. Since radios need to operate on the same frequency in order to talk to each other, is not possible to match their frequencies.
Ans: VHF Radios are used mainly in outdoor applications which have few obstructions and can be used in line of sight (Boats on water, Oil fields or Motorcyclists for example) and under these circumstances the radio frequencies will travel further. UHF Radios are used when working in and around buildings or are faced with other obstructions as the frequencies penetrate walls, steel structures and the "other" obstructions better.
Ans: Depending on: work cycle, battery chemistry, and charging cycles one should expect 1 to 2 yrs. Like a cellular phone, Talk time also varies but you can expect up to 10 hrs per day.
Ans: The battery. If the battery charge is low, radio features are not dependable. Make sure the battery is fully charged and holding its cells before proceeding to other steps. if the still problem then replace the battery after approximately 15-18.The symptoms are- low talk time reduced range and frequent low battery beep. If the received signal is cracking or noisy, just move a few away from these blind spots. The signal will improve. In case this does not happen, you are possible getting out of the communication range. Reduce the distance of communication between the walkie talkie.
Ans: YES: AS per WPC (DOT) Regulation (require all radios operating license band frequencies 1 watt or more to require a license)
Ans: Two way radio Coverage is dependent on power, antenna height and terrain. On-site portable radios will typically cover from 1 -3 km in radius (4-5 Watt UHF / VHF radios), while wide-area radios can offer coverage up to a 10-15 km radius with a repeater.
Ans: Cost and group contact capabilities. Two-way radios are easy to use with a push-to-talk feature which enables the user to communicate instantly with anyone or an entire user group on the network. Two-way radios are designed to be utilized in extreme conditions and offer rugged features. There are no monthly fees or per minute airtime costs regardless of your talk time usage amount.
Ans: Best not to do so and best to turn off the radio in the charger as the battery will eventually discharge due to the radio using more out than the charger is putting in
Ans: All of our business Radios come with a one year warranty from the date you purchased the radios. Please contact us for warranty issues so we can service info@antrikshtechnosys.com 011-49055077
Ans: Two way radio is a hand held device or transceiver can both transmit and receive voice communication. Broadcast environment use receiver meaning one can receive voice but not transmit communications. other terms for two way radios include; walki talkie, hand held radio or handie-talkies.the three types of two way radios are; hand held ,mobile, and base station and Repeater station.
Ans: A two-way radio device which typically resides at ones desk or in a control station. base stations are located in a control center or hubs used by: airports, police stations, hospitals, taxi cab station, security company base, etc base station help direct traffic" of two way radio and land mobile radio system user in the field.
Ans: mobiles are designed to be mounted in cars or boats for higher powered communication( communicating over longer distances) mobile radios typically have 60 watts of power while professional hand held radio have only 4 watts of power. Mobile radios are typically used by emergency first responder, public works organizations, or companies with large vehicle fleets and numerous field personnel.
Ans: A device that is installed at a fixed location and whose sole purpose is to receive a signal and then retransmit the same signal at a higher strength. Repeaters are used by institutions such as police departments and hospitals to transmit signals over a longer distance than the Two-Way Radio was previously capable of. Installing a repeater commonly used to eliminate a "Dead Spot" in a building or town.
Ans: A feature that detects when the user begins to speak and automatically turns on the transmitter, nullifying the PTT switch. VOX Mode is undesirable in noisy environments.
Ans: VHF denotes frequency range from 136 MHz to 174 MHz. VHF signals travel low to the earth's surface. In the country or a rural area with fewer buildings and less obstacles VHF is a better choice for communication needs.VHF is typically used in "line of site" applications where the transmission is travelling over greater distances with less physical obstructions. Users of VHF would be boats on the water or motorcycle riders who want to maintain contact on the road.
Ans: High frequency (HF) the range of radio of frequency electromagnetic waves (radio waves) between 1.8 to 30.0 MHz It is also known as the decametre band or decametre wave as its wavelengths range from one to ten decametre (ten to one hundred metres). Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher frequencies is known as the very high frequency (VHF) band.
Ans: A radio system that allows multiple users to use the same set of frequencies in a small area. This is done by using computer controlled repeaters and pre-assigned talk group numbers.
Ans: A button, typically on the side of the radio or on the external headset, that when engaged activates the microphone for transmission. It is important to note that only one radio can transmit on any given radio channel at one time.
Ans: UHF denotes a frequency range of electromagnetic waves between 350 MHz and 390 MHz As UHF frequencies use a shorter wavelength they are generally used when working in and around buildings as the communication waves penetrate walls and steel structures best. The UHF frequency band.
Ans: The Citizens Band (CB) Service is in the 26.965 – 27.405 MHz spectrum range. The most common use of CB spectrum is short-distance, two-way communications using small, portable hand-held devices that function similar to walkie-talkies.
