Newbie here, so haven't found how to search topics yet.<br>
<br>
I have a project where I have an arduino housed in an enclosure with a <br>
baofeng bf-888s. I want to be able to leave the radio on channel one, <br>
and program both pre-stored frequencies, as well as manually entered <br>
frequencies. The arduino is tied to the audio in and out of the <br>
radio. I know enough about arduino coding to generate square wave <br>
output and detect square wave input, vary frequency of the data <br>
pulses, duty cycle, etc.<br>
<br>
What I don't know is what is the protocol for sending a "code plug" to <br>
the BF-888s. Anyone know where to steer me? Mr Google doesn't seem <br>
to understand my question.<br>
<br>
