OpenGD77

This forum is concerned with OpenGD77 which is an open source firmware developed for Amateur radio use only. It is not suitable for commercial use and will invalidate any FCC approvals.

For your application you are better off staying with the official firmware. This forum may not therefore be the best one for your needs.

Additionally the firmware does not support any form of encryption, and will never support encryption, because its illegal for Amateur radio operators to use encryption.
