Using the BCH-270 Programming Software, Volume 1.0, by Jim Cason

  1. Beginning: Make sure the radio is “OFF.” Connect the radio to a computer with the programming cable (radio first; computer USB last).
  2. Turn radio “ON.” Run (turn on) the program. Click the “PORT” button. If a port has been chosen, it will be indicated. In some cases, Port 3 will be chosen. Click “OK,” or choose one, then click “OK.”
  3. Now click the “READ” button which will read the list of frequencies and/or associated data from the radio. If you don't care what is in the radio, then skip this step.
  4. You may now choose and input the frequencies, including the “point” ( . ) into the “A” or “B” channels, as desired. If a repeater has a tone, choose it from the pulldown in columns QT/DQT Dec and QT/DQT Enc, as necessary.
  5. Radio output power may be chosen from column labeled “Power” and choosing “High” or “Low” from the pulldown. Other parameters may be changed IF YOU KNOW WHAT YOU ARE DOING. When you have input the proper frequencies and/or associated parameters, you may click the "SAVE" button to save the radio programming file. 
  6. When ready to put the frequencies and/or data into the radio, click the “WRITE” button; “OK” the port. You are now finished. If you have made any changes, remember to “Save” the data file into the previously used file or make a newly named file. Further modifications may be accomplished in the future by modifying the previous existing radio programming file and running this procedure again.
