Recommended Frequencies Need Updating – AV Tools Review

I realize the app is made in the UK, but with the ability to switch to Imperial for US standards, I’d like to also see current frequency recommendations be updated as well. The 600mhz range in the states has been bought up and wireless mic systems have to migrate to over frequency locations. I think 500mhz band is not the place to go. Hoping to have this added as a huge help to my AV profession.
