Bearcat BC140 scanner mod file One can convert this scanner from a 10 channel machine to 16 channels. All one need do is remove a diode. >Turn off the power, unplug the power source, and remove the antenna. >Turn the scanner over and remove 4 screws. >Carefully seperate the cabinet halves, carefully as the two are wired together >Locate the corner of the main board where the connectors for the front panel are. See the 30 pin IC that says "Uniden". Near this IC is a diode with insulating tubing on its leads. One end of this diode is connected to the topside of the board, and the other goes over the edge of the board and is connected to the underside of the board. >Clip a lead or remove this diode. >Reassemble the scanner. >You should have 16 channels now. Program them just like you would the others.
