I am currently working on a project to build an enhanced Fox Hunt set with a few features, most notably the ability to change broadcast frequency on a BOAFENG GT-3 and send a message by reading text from a CSV and putting this through Text to Speak. 

I currently have everything working except for the ability to make frequency changes through the command line.  Can anyone point me in the direction of the correct documentation or give me a quick rundown of the console commands needed to either change the frequency or replace the pre programmed frequency list on the fly via the Linux console?

Fully aware I may be going about this an arse about backwards way, so if there is a better way of achieving this I am all ears.

Regards,

Randie
