ADes the new updated mod file for the ADI AR-147.

If you have the old version, follow this one:

1. Remove the bottom cover by removing the four screws.
2. You will see 2 (two) red jumpers. One located on the board, and one that 
looks like it comes off the LCD.
3. Cut both of these jumpers, and move them so they will not touch again.
4. Replace the bottom cover and the four screws.
5. When powering on the unit after making the mod, you MUST reset both the 
CPU and the VFO. (Look in the instruction manual for learning how to do 
this.)

Your unit will now successfully Transmit and Receive from 130.0000 MHz to 
179.9950 MHz. (Please note that the unit will NOT transmit in the Aircraft 
Receive Band Mode.)

4. Replace the bottom cover and the four screws.
5. When powering on the unit for the first time after the mod is done, you 
will need to reset the CPU and the VFO. (Your instruction manual tells you
