Hello my name is Juan, this text talk about the mods for transceivers of Ham Radio... I hope you interest this... If you need mods for others tranceivers, ask me.... BE CAREFUL! Procede at your own risk. Dont forget that transmitting outside the amateur band is not allowed so please consult your local athorities for a special permit. THANKS EA5SP.EA5FDS.EAV.ESP.EU.WW THIS MOD IS FOR THE ALINCO DJ-500T, IF YOU HAVE LITTLE OR NO SOLDERING EXPERIENCE DO NOT !!! REPEAT DO NOT TRY THIS MOD ON YOUR RADIO. IT IS NECESSARY TO REMOVE A CHIP RESISTOR FROM THE CPU BOARD. TOOLS YOU WILL NEED: # 0 PHILLIPS SCREWDRIVER 25 WATT SOLDERING PENCIL, EXACTO KNIFE. I RECEIVED A SCHEMATIC AND BOARD LAYOUT FROM ALINCO FREE. PHONE 1-213-618-8616. OR SEND A SASE TO ME AT : BRYAN TODD 318 ALDRICH ROAD HOWELL, NJ 07731 AND I WILL SEND YOU A COPY OF THE BOARD LAYOUT. 1. REMOVE THE BATTERY PACK 2. REMOVE 3 SCREWS FROM THE BACK OF THE RADIO 3. REMOVE 2 SCREWS FROM THE BOTTOM (FRONT PANEL SIDE) 4. SPLIT THE CASE CAREFULLY. 5. PUT THE RADIO FACE DOWN ON THE TABLE WITH THE TOP AWAY FROM YOU. THE SPEAKER AT THE BOTTOM. 6. FIND THE "D" SHAPED GOLD PADS UNDER THE SPEAKER ON THE RIGHT SIDE OF BOARD. 7. THE CHIP RESISTOR IS TWO PADS UP FROM THE "D" SHAPED ONES. THE NEXT STEPS CAN CAUSE GREAT ILLNESS TO THE RADIO !!!!! 8. VERY CAREFULLY HEAT ONE END OF THE CHIP AND PRY WITH KNIFE. 9. THEN HEAT THE OTHER END AND REPEAT UNTIL RESISTOR IS OFF THE BOARD. 10. HOLD THE BATTERY PACK IN CONTACT WITH BOTTOM OF RADIO, TURN ON RADIO, PRESS THE RESET BUTTON WITH TOOTHPICK (HOLE UNDER PTT SWITCH). 11.
