MR8100 – UNIDEN Scanning Mobile Receiver 8100

Custom Software Advantages

     By using a PC, the full functionality of the MR8100 can be realized. Frequencies can be changed individually, or all one hundred channels may be programmed at once by just pressing a function key. If multiple MR8100s need to be programmed, the software will accomplish the task in a minimum of time.

     The primary function of the software is to provide a means to “program” the MR8100 scanning receiver in terms of frequency and descriptive text assignments. The current contents of the radio’s memory can be retrieved and updated as required. A printout may be generated for reference.

     In a typical scenario, a set of frequencies and descriptions can be entered into a PC at “base” without tying up the radio. Then, after a printout and confirmation of its accuracy, the data can be transferred to the scanner when it is convenient to do so. If you are using a portable or laptop PC this can be accomplished without removing the radio from its operating position. It takes about one minute to load a complete set of one hundred channels into the MR8100.

     For even more flexibility, multiple files of frequency data can be saved on your PC’s disk. For example, one file could contain HAM repeaters and another could contain fire department or ambulance frequencies. The scanner can then be quickly configured for whatever scanning task is required. Only a minimum of keystrokes is required, making the software practical for in-the-field use.

In summary, the frequencies of the 100 channels as well as a textual description visible on the scanner’s LCD panel can be defined using your PC.

Other functions of the MR8100 such as scanning speed, “hold”, and “manual” control, volume and squelch adjustments can only be performed via its own keyboard.

     The UNIDEN scanning mobile receiver MR8100 can be programmed using an IBM PC or IBM PC-compatible computer. The additional features this method provides which are beyond the capabilities of the MR8100 by itself are:

  • access to frequencies in the 824 to 849 MHz range and the 869 to 894 MHz unavailable via MR8100’s own keyboard

  • definition of 16 character textual description for 100 channels – will display on the MR8100’s LCD panel when frequency is tuned.

  • definition of 16 character textual description for 10 banks – will display on the MR8100’s LCD panel when bank is activated.

  • restriction on specific channels to prevent alteration via MR8100’s own keyboard

  • retrieval of stored frequency information in the MR8100 – file storage on the PC and printout using a printer.

  • convenient mass programming of a number of MR8100 radios.
  • In addition, custom software can exceed the capabilities of the “official” version by providing enhanced functionality as itemized below.
  • Unrestricted programming of 800 MHz frequencies – no password required.

  • There is no need to turn it off/on to make it usable after data transfer. The radio continues scanning automatically and its keyboard is unlocked immediately after data transfer. This feature can be disabled.

  • Fastest data transfer speed: download of data – 40% to 60% faster, upload of data – 10% to 30% faster. Slower computers experience the higher percentage gains.

  • Partial download of only those frequencies changed – less than 2 seconds to approximately 1 minute depending on quantity, instead of entire file each time. The software “remembers” which file was last sent so that only new changes need to be sent. Date/time of last download is saved in radio to ensure that it contains up-to-date data.

  • Bank active detect and activate/deactivate via software.

  • Choice of COM1 or COM2 serial ports provides additional flexibility.

  • More robust error detection for data transfer problems such as unusual radio status or printer problems.
