I was able to place the IC-746, power supply and a speeker on the shelfe and it all seemed to fit pretty good.

I used picture hanging cable and added ends to it to be able to attch it to bolts to clamp
down the IC-746. I did use 2 pieces of rubber to help hold it still and not damage the radio.

Next was to make sure it would all fit in the case with the main parts in there.

Next I picked up a Bioenno battery and a Powerwerks distribution block. I wanted to make sure
I could run off battery or regular power, depending on where I was setting up.

Then I was able to put it back in the case and start running wires and start seeing how it was all going to finally look like.

I did have to install an external tuner due to the internal tuner not working on the IC-746.
I had to mount it to a shelf that I installed upside down in the top of the case.

Lastly I had to install a voltage monitor as well as USB and power outlet for charging cell phone or whatever I needed to power.

With it all together, I was able to take it out and use if for a bunch of activations as well as taking it with me on vacation.
