This is my third and hopefully last revision. I decided to mount my radios under the shelf. This way they were out of the way and eye level when I sat at my desk. The BCT15 on the top shelf is for the live feed for radio reference. I would have mounted the 15 on the shelf with the rest of the radios but having 5 radios spread across made it hard to read the displays on the end radios. Having 4 works out best and I never mess with the live feed radio.
