Subject: EXPANDED RX / TX MOD FOR ALINCO DJ-S41

       Performing this modification will void any warranties.
       All standard disclaimers apply. This mod is for the 
       DJ-S41T, and not the DJ-S41(C) 10 mW version.

    1. Place the radio face down on a soft towel. This avoids 
       scratching the display and gives you a place to put 
       the seven tiny screws to be removed.

    2. Remove the batteries.

    3. Remove the three screws on the upper rear cover, and
       the four screws inside the battery compartment. The
       rear cover can be lifted and removed easily, as there 
       are no wires to be concerned about. The antenna 
       connection is made by means of a gold-plated spring 
       contact.  

    4. Look for a small (about 1 mm) green surface mount 
       resistor (actually a 0 ohm jumper), located on the far
       left side of the exposed circuit board, located to the 
       "northwest" of the speaker. There is a marking in white
       letters, OP/CL, this resistor is over the top of the "P".
       It is the only green component visible on the board.
       (This radio does not have the traditional Alinco red 
       and blue wires which have become so familiar...)

    5. Carefully remove this resistor, using a small tip soldering
       iron, tweezers and a steady hand. 

    6. Re-assemble the radio, being careful that the thin rubber 
       gasket is seated around the inside edge of the rear cover.
       Replace the batteries, press and hold the "F" button on the 
       left side of the radio, and turn it on. The display should 
       show all segments and markings. Release the "F" button and 
       the radio will now be capable of operating from approximately 
       425 MHz to above 470 MHz, depending on the VCO's tuning. 
       The display will blink if the VCO is taken out of its range.
       Re-tweeking of the VCO is not recommended. 

		    THE NOT-SO-FINE PRINT:

    7. Although reception on the expanded frequencies is legal, 
       transmission is not. This unit is not FCC type-accepted
       for anything but ham band (425 - 440.995 MHz) operation.
