Do police use encrypted radio?
Police can encrypt their radio communication so their conversations cannot be monitored by outsiders.
What’s encrypted varies from state to state (& sometimes county to county) all over the US as each state makes it’s own laws regarding encryption.

Is 2 meters UHF or VHF?
The 2-meter amateur radio band is a portion of the VHF radio spectrum, comprising frequencies stretching from 144 MHz to 148 MHz in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and …
Can VHF talk to CB?
1 Answer. CB or its close relatives fall into the HF frequency range (covering somewhere around 26 to 28 MHz, depending on country), so anything that accurately calls itself a VHF radio will not transmit (and most likely will not receive) CB. … Therefore it cannot receive or transmit on CB frequencies.
Does VHF or UHF have longer range?
For most applications, lower radio frequencies are better for longer range. A broadcasting TV station illustrates this. A typical VHF station operates at about 100,000 watts and has a coverage radius range of about 60 miles. A UHF station with a 60-mile coverage radius requires transmitting at 3,000,000 watts.
Why are Baofeng radios so cheap?
One of the reasons the Baofeng UV-5R radios may be so inexpensive is they are not aimed at a specific Niche, therefore they save money on big advertisements and promotions like the ham radio equipment manufacturers like Yaesu Icom and kenwood. They also do not test and advance any technology.
Who uses UHF frequency?
They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications. The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz.
How far can a two way radio reach?
Wattage and Range of Coverage: Many two-way radios claim they have a range up to 25 miles in optimal conditions. Real-world conditions are usually not optimal, and in most situations, a radio’s actual range will be about 2 miles or less.
Which radio frequency is best?
How to Select the Right Two Way Radio Frequency?VHF (Very High Frequency) at 136-174 MHz. Best Fit For: Outdoor usages where high range is necessary along with very less or no obstructions. … UHF (Ultra High Frequency) at 403-470 MHz. Best Fit For: Indoor requirements or environments with hindrances. … 900 MHz Onsite.

Does UHF and VHF still work?
Today digital television is broadcast in the UHF band, but VHF is still used for FM radio and marine-band radio, and amateur radio enthusiasts still broadcast on both bands. Because of the different characteristics of the two frequency bands, the optimal designs for UHF and VHF antennas are significantly different.
What happened to UHF?
UHF generally had less clear signals, and for some markets, became the home of smaller broadcasters who were not willing to bid on the more coveted VHF allocations. These issues are greatly reduced with digital television, and today most over-the-air broadcasts take place on UHF, while VHF channels are being retired.
Is VHF line of sight?
It depends somewhat of what you mean by “VHF”. The frequency range of 30 to 300 MHz that is defined as VHF does not normally support any other propagation modes than ground or surface waves. These are limited to line-of-sight and sligthly beyond using “reasonable” antenna sizes and power levels.
Is the Baofeng UV 5r illegal?
591 mean that all Baofeng UV-5R and UV-92 radios (which can transmit [on] FRS and GMRS frequencies) will become illegal to buy or sell in the U.S. after September 2019, even for amateur use? To which, Stone replied, No. Those devices to not have Part 95 certification, so they are not authorized for use in FRS or GMRS.
What is the range of VHF?
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter.
Is VHF or UHF better?
In general, UHF radios are better for indoor use because their wavelengths are shorter and better able to penetrate through steel and concrete. … VHF radio signals tend to degrade more than UHF signals indoors.
What are UHF and VHF frequencies?
According to US frequency groups there are four different categories: low-band VHF (49-108 MHz), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz), and high-band UHF (900-952 MHz). The FCC is in control of who operates within each specific band and if anyone has priority over other operators.
Can Baofeng talk to CB?
Nope, it can’t. Provided you mean North/South America CB, no it is not possible. … CB comes in at the 11m band (around 27MHz), versus these radios are only capable of 130-500MHz. Even if software modified and programmed, it would not be able to transmit nor receive anything.
Are BaoFeng illegal?
Yes they can. The amateur radio service is regulated by FCC Part 97 rules and do not require a part 90 certified radio to operate on those bands. So you can use your older Baofeng UV5R and UV5RA radios on the 144-148 Mhz 2 meter band and 430-450 MHz 70cm bands without fear of being in violation.
How far can a Baofeng reach?
The range of your transmission is influenced by using a repeater. The range of your receiver is a completely different thing. Your Baofeng UV-5R is a transceiver: that is, both a transmitter and a receiver. With a full battery and in full power mode, it will give you a range of about 10–20 km depending on obstacles.
