The Pro 2006 is a Great mil-air scanner! I have a “Bill Cheek” special that I modified
with carrier receive, center frequency tune, s-meter, all of these are led’s.
The only drawback to the 2006 was the back light for the lcd display.
The brightness of the display got weaker and weaker over the years and eventually
went completely out.
There are people that have replaced the back lighting, and it has been discussed here on RR.
If you are able to find one, make sure and check out the brightness of the back lighting.
FWIW you can’t go wrong with the BCT-15X, I have 2 and they are my go to for aviation
communications (mil-air & civilian air).
Good Luck,
