What are the logical channels used between MS and BTS?
Broadcast Control Channel (BCCH)-DOWNLINK- This channel contains system parameters needed to identify the network and gain access. These paramters include the Location Area Code (LAC), the Mobile Network Code (MNC), the frequencies of neighboring cells, and access parameters.Frequency Correction Channel (FCCH)-DOWNLINK- This channel is used by the MS as a frequency reference. This channel contains frequency correction bursts.Synchronization Channel (SCH)-DOWNLINK- This channel is used by the MS to learn the Base Station Information Code (BSIC) as well as the TDMA frame number (FN). This lets the MS know what TDMA frame they are on within the hyperframe.* The BSIC was covered in the Introduction to GSM Tutorial. You can also read about the numbering schemes used in GSM.Cell Broadcast Channel (CBCH)-DOWNLINK- This channel is not truly its own type of logical channel. The CBCH is forpoint-to-omnipointmessages. It is used to broadcast specific information to network subscribers; such as weather, traffic, sports, stocks, etc. Messages can be of any nature depending on what service is provided. Messages are normally public service type messages or announcements. The CBCH isnt allocated a slot for itself, it is assigned to an SDCCH. It only occurs on the downlink. The CBCH usually occupies the second subslot of the SDCCH. The mobile will not acknowledge any of the messages.

01) Press Manual to enter the manual mode. 02) Enter frequency. 03) Enter channel number (e.g. for channel 1, enter 01). 04) Press Manual again. Note: When entering a number of channels, you can start at step 2 after the first frequency is entered.
How do you program a BC370CRS scanner?
http://www.uniden.com/pdf/BC92XLTom.pdfThe manual knows all.Straight From the Manuel:Storing Known FrequenciesInto Channels1. Press Hold. Then enter the channel number where you want to store a frequency, then press Func and Pgm. The channel number appears.2. Use the number keys and to enter the frequency (including the decimal point) you want to store.3. Press E to store the frequency into the channel. Notes:• If you entered an invalid frequency in Step 2, Error appears and the scanner beeps three times. Enter a valid frequency.• The scanner automatically rounds the entered number to the nearest valid frequency. For example, if you enter 151.473 (MHz), your scanner accepts it as 151.475.• When you enter a frequency into a channel, the scanner automatically turns on the delay function and DLY appears. When delay is turned on, the scanner automatically pauses scanning2 seconds after the end of a transmission before scanning proceeds to the next channel. To turn the function off or on, press Func + Dly.• If you enter a frequency that has already been entered elsewhere, the scanner sounds an error tone and displays the channel that was duplicated. If you entered the frequency by mis- take, press then enter the correct frequency. To enter the frequency anyway, press E to accept.4. To program the next channel in sequence, press E then repeat Steps 2 and 3.
How do you program Z 45 regency scanner?
To program the Regency Z30 TURN UNIT "ON" 1. Press "MANUAL" 2. Enter the frequency you want, example 162.475 3. Press "ENTER" The display will show "Ch_" with the _ (underscore) flashing 4. Enter the number of the channel where you wish to store the frequency. Note: channels 1 thru 9 must have a zero before them, example 01, 02,........ 09 If you want to add more frequencies at this time, got to step 2. To lock out a channel, press "SCAN" and while the unit is scanning,enter the channel number. Repeat this action to unlock a channel. To increase or decrease the scanning rate, press the "SPEED / ENTER" key while the unit is scanning. To create a delay after a transmission, press the "DELAY" key while the unit is scanning. You can change the display by pressing the "CHANNEL / DISPLAY" key. There are 3 choices: display only the channel number, only the frequency,or alternate displaying the channel number and the frequency.
Why do you not get the signal for the channel but you see the number?
Because the number you see is your tv tuning to that frequency if there is no signal than try replacing your cable ends or if needed the whole line it is cheap
On a Motorola portable radio what is the difference between channel and frequency?
Not only on Motorola Portable radio, but in all radio communications: Frequency is number of cycles (full change circles) per second. When radio device operates on some frequency it requires band of adjacent frequencies to be able to transmit modulation (information) too. To avoid mixing, next transmitter must take some "distance" (higher or lower frequency) far enough from frequency of the first one. According to regulations basic frequencies are "named". Channel number is the name of its frequency given by communication regulations. For example, TV UHF channel 21 takes all frequencies from 512 to 518 MHz (megahertz), channel 22 from 518 to 524 MHz, and so on... CB Radio channels 21 and 22 occupy frequencies from CB band, not from TV band. Tables of channel frequencies within various bands can be easily found by search engines.
How do you program regency scanner model r1077?
One should program a Regency Scanner with the model number r1077 by first turning the device's power on. Then press the manual button until the channel wanted is shown. Once the channel number is shown hit enter, which will make the frequency channel that number. Then one can go to the next channel number and hit hold, or delay, to hold the number for dispatch. In order to lock certain channels one should hit the lock button when the channel number comes up instead of enter, and this will keep that particular channel locked.
