As you see above, 66-88 and 806-956mhz can be inabled!

​

For 66-88mhz, move the resistor located on the right, too the location marked in yellow, this add's 66-88mhz band.        NOTE:  29-54mhz is removed by this mod!

​

For 806-956mhz, move the resistor directly below the the empty solder pads too the location marked in yellow above that resistor.         NOTE: No bands are lost!      

​

There seem's to be a rather interesting drawback with adding the 800mhz band.

​

  There ALSO appears to be a drop in receiver sensitivity on the VHF and AIR band due too this modification.      

 

  I will reverse the 800mhz band to verify my findings.

​

 After some careful testing with the service monitor, there was NO drop in receiver sensitivity as i had first thought.  So, we are still good to go in this part of the modification.

​

 The next modification is too keep the back light on 100% of the time once that button is pressed on the front panel.
