We built a real-time 5GHz spectrum analyzer into Bolt 3000 receivers. This will be a free firmware update in the near future, but we're looking for some beta testers to give it a shot. We used it extensively at IBC this year and it came in super handy. There is no better way to quickly scan for the best channel to set your Bolt system to.
If you're interested in giving it a go, shoot me a private message and ill shoot you over the new firmware. It will be available for the 1000 and 500 just after its officially launched for the 3000.
