Questions and Answers for Uniden 800 MHz Bearcat Base and Mobile Scanner with Narrowband Compatibility

A:  Yes, this is able to by plugged in and used immediately.

A:  Think of a wave. A nice rolling wave way out in the ocean. (Not one getting ready to crash onto shore!) The surface of the wave is not broken up but is a smooth one. Now take that image and put if onto the old x-and y- charts of your school days. Where the wave meets the x-axis (the sideways line of the chart) every so often is called the frequency. The height of the wave is called the amplitude – or in radio, the signal strength. That is how an ANALOG signal looks on a graph. Now, take your wave and imagine it chopped up into literally millions of bits along the sideways line – again, your x-axis. If you have enough of the chopped up bits put side by side but each bit has a very distinct value they will begin to look like a wave. That is how a DIGITAL signal looks on a graph. That means that while the signal is changing, like the surface of the wave, it is being broken up into millions of pieces that are added together to form the same wave surface – almost. Digital signals only work as either being there (which all the electronics interpret as a “1” or “plus” value or NOT being there which is interpreted as basically a “0” or zero. This same logic applies when you hear the term sampling rate for all modern digital music systems and others.

A:  The item in which your viewing is sold at home depot.com and can be purchased on a credit card on there web site or you may take a check to the store for purchasing provided they carry it in stock.

A:  This scanner is Analog not Digital. Includes the most interesting "action" bands where you can hear police, ambulance, fire, amateur radio, public utilities, weather, and more. 25-54,108-174,406-512,806-956 (excluding cellular)

A:  Digital.

A:  This is a analog scanner only

A:  This scanner is analog.

A:  This is a good, basic scanner for the money. As such, it is analog only. Will not receive digital signals or trunked transmissions. Bearcat makes such scanners, but they are considerably more expensive.

A:  This model is analog & does not support trunked frequencies. It would be suggested to research your area further on what systems & system types they use in your area & then search for a model that would support those systems in your area.

A:  ANALOG ONLY!!

A:  No it is not set up for trunked frequincies

A:  Scanners are tuned to certain frequencies you might be looking for. Most people choose Police and Fire frequencies just to see what's up with their cops and fire departments. Basically, anything that generates an electronic signal is disturbing the atmsopshere at the frequency it is broadcast on. Scanners merely look for those disturbances at given frequencies. Common examples are AM/FM stations have LICENSES to BROADCAST at certain FREQUENCIES. (That's why you TUNE the radio. To get to the frequency of the STATIONS assigned FREQUENCY. When your scanner detects a SIGNAL of sufficient strength, it can trigger the AMPLIFIER circuits in the scanner and internally reduces the signal (which will always be at frequencies WAAAAY beyond what human ears can detect) to a range of frequencies you can hear by using audio circuits. So, to efficiently use a scanner, unless "you're just reading the news" and let it search on its own, you can find the freqeuncies you are interested by using internet sources like https://www.radioreference.com/apps/db/.

A:  Scanners pick up two-way radio transmissions and/or paging system transmissions, from CB radios to police/fire/EMS to aircraft & NASCAR transmissions. Scanners scan particular radio bands and lock in on transmissions on whatever frequencies the user programs into the scanner. The BC355N is a good value for a first-time scanner. It has lots of channels available for programming frequencies.

A:  It would depend on if they use analog frequencies in your area. It would be suggested to research your area to see what type of systems & system types they use in your area. You can then look for a model scanner that would support the systems & frequencies in your area.
