A: It is a terminology to imply that the scanner will be used at the hi end of frequency as opposed to low frequency
To program the Bearcat BC60XLT scanner in Tennessee, start by identifying the frequencies used by local agencies, which can typically be found online through databases like RadioReference. Turn on the scanner and use the manual to enter the frequencies into the appropriate memory channels. You can also use the frequency search function to scan for active channels. Lastly, save your programmed frequencies and ensure the scanner is set to the right mode to listen to those channels.
There are several different scanner frequencies for Floyd County in Kentucky. The 911 dispatcher frequency is 154.80000. Law enforcement is 154.81500, 155.31000 or 155.06250.
The frequency is likely a "birdie" on the second scanner -- meaning that the scanner circuitry produces a signal noise. This is common, and many scanner manuals provide a list of "birdie" frequencies.

To program a Cobra SR900 police scanner, you'll need to input frequency codes for the specific services you want to monitor. Common frequency ranges for police and emergency services typically fall between 150-160 MHz for VHF and 450-470 MHz for UHF. You can find local frequency codes through online databases or scanner forums. Once you have the codes, enter them into the scanner using its keypad or programming software.
To delete a frequency on a Bearcat BC 147XLT scanner, first, ensure the scanner is in the correct mode (e.g., frequency or channel mode). Navigate to the frequency you wish to delete using the UP/DOWN buttons. Once on the desired frequency, press and hold the "DELETE" button until you hear a confirmation beep. The frequency will be removed from the memory.
To program a frequency of 139.21000 MHz into a BC 142XL scanner, first turn on the scanner and press the "MANUAL" button to enter manual mode. Then, use the keypad to enter the frequency as "139210" (the MHz and kHz are implied). After inputting the frequency, press the "E" or "ENTER" button to save it. Finally, you can press the "SCAN" button to start scanning or "MANUAL" again to listen to the programmed frequency.
The first digital police scanner was invented in the 1970's. Unlike earlier analog version (which were basically AM Radios, as police just used to broadcast using regular radio waves), this scanner was the first to allow you to punch in a frequency to search for the police frequency.
