Modified Radio Scanner
The modified radio scanner designed to most efficiently receive the transmitted signal of all transmitters available on this site. resulting with extended receiving range and superior sound quality.
Your scanner's scan speed is a measure of how many channels it scans through each second.
Search speed measures how many frequency "steps" are searched each second.
High scan and search speeds are important when scanning many channels at one time or searching a large radio band.
The Uniden BC92XLT scan speed is 50 channels per second (max).
Search speed is 60 - 180 (max) steps per second.
Frequency steps are a measure of the leaps the scanner makes while scanning a band of frequencies. It is measured in kilohertz (kHz).
Some scanners are equipped with step selection which allows the user to override the scanner's programmed search step selection and is useful for monitoring stations that use unusual channel spacing.
This scanner is not equipped with search step selection.
The Uniden BC92XLT frequency step (within the relevant band 806.000 - 956.000 MHz) is 6.25 kHz.
The frequency steps were decreased more then 10 times over with the modified radio scanner.
The purpose of the modification is to allow you to "zoom in" as close as possible to the frequency used by the transmitter (phone or room).
The frequency of the transmitters (phone or room) is based on Crystal, an electronic part which produces very stable and precise controlled FM narrow band.
The quality of the received voice signal is in direct relation and increases significantly with the ability to pin point to the exact transmitted frequency.
One way to achieve this is to decrease the scanners frequency steps (smaller steps on the same band).
Smaller steps will result with increased precision but with longer scanning time.
Fortunately we need to scan a defined small band of frequencies. Look for the documentation on how to program your scanner.
Sensitivity is a measure of the lowest signal strength required to detect a station. It is measured in microvolts (uV). A smaller number indicates a more sensitive receiver since less signal strength is needed to detect the station. Sensitivity is primarily of importance when listening to weak signal transmissions.
The Uniden BC92XLT sensitivity (within the relevant band 806.000 - 956.000 MHz) is 0.4 uV.
the squelch option of the scanner will allow you to listen to phone calls and auto record only when the phone line is in use.
No lengthy silent moments or "white noises" in between calls or when analyzed in the future.
To record and listen to the phone conversation, use one of our Digital or Cassette Recorders.
Loud clear and extended reception range of both room and phone transmitters, with or without headphones.
using the modified Radio Scanner you'll be able to receive the transmitted voice signal from all of our room transmitters.
If you need to record the room conversation as well, use one of our Digital or Cassette Recorders.

Modified Radio Scanner
The radio scanners sold on this site are modified versions of those found on the market today. the modification purposes are to improve range, quality and clarity of the received signal.
the radio scanners offered on this site are chosen and tuned for best performance in correlation with the phone and room transmitters.
Although you can use any scanner with the following radio scanner features it is not guaranteed to perform in the same sound quality range or any other indicated performance of radio scanners sold through this site.
Please note: we can not provide any tech support regarding the programming, installing, resetting, downloading recorded media to your PC or any other usage of items not purchased through this site.
Required Scanner Features
based on the level of the received signal strength
Modified Radio Scanner
To record the received voice signal you have to connect the Modified Radio Scanner to a Digital or Cassette recorder also available on this site.
White Noise
Meaningless acoustical noise of which the intensity is the same at all frequencies within a given band.
Squelch
an electric circuit that cuts off the receivers output when the signal becomes weaker than the background noise.
Digital / Cassette Recorders
To record the received voice signal you have to connect the Modified Radio Scanner to a Digital or Cassette recorder - also available on this site.
In order to record automatically the recorder must have:
- voice activated feature sometimes called AOR, VOR, VOX or VAR.
- External microphone (MIC) jack.
- accessories to connect the recorder (Digital or Cassette) to the Modified Radio Scanner.
Channels
A specific radio frequency or band of frequencies, usually in conjunction with a predetermined letter, number, or codeword, and allocated by international agreement.
Quartz Crystal
An oscillator that uses a quartz crystal to generate a frequency. Such devices generally output a fixed frequency, but some can be controlled by a tuning voltage over a small range.
