TH215.4 Kenwood TH-215A / TH-215E Frequency Modification. _____________________________________________ I'm not quite sure why we all do this, but here's how anyway. In order to increase the frequency coverage of the Kenwood TH-215 Series Handheld Transceivers, a few jumpers inside the radio need to be cut. No retuning is necessary. WARNING: The radio is compact internally; if you do not have the delicate touch of a surgeon, forget this mod or get a radio surgeon friend to do it for you. Tools you will need : #1 Phillips Screwdriver #2 Phillips Screwdriver Diagonal Cutters (Very Small!) Remove the Battery Pack, Antenna and Belt Clip. Remove the 4 small screws in the recesses near the 4 corners of the back of the radio. Do not separate the cases yet! Place radio on a clean soft work surface Face-Up. With the antenna connector facing away from you. Lift the front case of radio STRAIT-UP. When clear of the rear case, rotate the front case to the right and lay it on the work surface Face-Down. Do Not Damage the Flat Cables. KEEP YOUR FINGERS OFF THE ELECTRONICS! Notice the 4 Copper colored jumpers on the surface of the circuit board inside of the front case cover. These are located 1.5 inches "NorthWest" of the center of the speaker. They are numbered J1 thru J4 from the bottom to the top. J3 is already cut on the TH-215A. Remove the jumpers as selected from the table below by cutting through the thin area at the center of the jumper. BE CAREFUL! Reassemble Radio. All memories will be clear and the display will be at the lowest Transmittable Frequency (i.e. 141 or 144). _____________________________________________________________________________ The Operating Frequencies are programmed by cutting jumpers as follows : Jumpers.
