- 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.

- 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.
