Subject: Mod the Standard C5900DA TriBand Radio.

For those of you who have been asking, here is the
modification for the new Standard C5900DA TriBand Radio.
This modification is only for those who are a active
member of a MARS organization or Civil Air Patrol.  To 
have this mod, you must serve in some type of communication
capacity in the respected organization.

Step 1.) With the radio facing you, remove the top cover 
         of the radio.
Step 2.) Near the front center of the radio, you will approx.
         observe 5 items in a row.
Step 3.) These are surface mount type capacitors and resistors, 
         you will need to remove RL99.
Step 4.) RL99 is not labeled on the PC board, so you will have to
         estiminate which capacitor is it by the below diagram.

       TOP BOARD

       *     *     *    *    *                     ******
     CL93   PAO   RL99 RL97 RL98

Step 5.) Remove RL99.  It will be right next to the
         empty slot.  Use a very fine tip iron at
         low heat.  A small toothpick and solder wick aids
         in removing the resistor.
Step 6.) Do a hard reset of the radio.  
Step 7.) The radio will now transmit 40-80, 100-180, 345-495 Mhz.


It is illegal to transmit on commercial or public service frequencies.
All unauthorized modifications of your radio will void the
factory warrenty.  Send a copy of your MARS/CAP license to Standard
Radio for authorization.
