Inside the rig, it really did not look quite like that ...    more like this:

...  12 (!)  (!) 11 
           (!) 13
      16 (!)  (!) 15

In addition to the published receive expansion, it also receives 800-950 MHz...
trunking radio, cell phone (I would *never* listen to that), 33cm ham band...

Have fun!
