Extended frequency for Alinco DJ-180
 
     

The modification for the new ALINCO DJ180 is very simple:
Just press the "LAMP"-key on switch on the unit and the range is from 130.000 - 173.995 MHz. For the RESET press the "F"-key (FUNCTION) and switch on the handy and it is in HAM-MODE from 144.000 - 145.995 MHz again.

Enjoy the handy, wich is very useful and snsitive on RX.

Just push function and Lamp button and switch power on to expand frequency.

Just push function and Monitor button and switch power on to go back to legal Frequently 144-146 Mhz.

This Mod is friendly to the memory's you stored, because everything will be in it 73

  • take battery off

     
  • take the four screws that hold the board that the battery contacts.

     
  • cut the loop of red wire that is in there. Tape ends so that they dont short out to the board.

     
  • put radio back together

     
  • hold function and turn on radio.

TX is now expanded to approx. 130-170 MHz.
