WARNING FOR THE 32-Ch HACK.
The channels 13 - 20 are the "stock" HD (Rx) bandwidths opened from the P4 to the RC. Some of us "hacked" the Rx RC band to be able to receive channels from 21 - 32..
Except for Ch 22, ALL the upper channels are used by Sprint cell carrier for the LTE 2.5G band. Sprint is the only cell carrier in the US to use the 2.5G band for their high band LTE data. The tower radios have an Tx/P output of 16W and a radius of about 1.5 miles from tower. If you set the RC on any upper channels and are close enough to the Sprint towers, the LTE signal will drown the RF from the drone to your RC. I have good luck with Ch 22 for now, but still have problems with GO app 3.0.0. If you have any questions about the upper channels ask me, I work for Sprint.
