[drats_users] Simultainious voice and data

[Dan Smith]

> Comments Dan?

I'm not exactly sure exactly what you're trying to say here.  If you
make your block size longer, then it will give you longer to talk while
the data is transmitting, that's true.

However, if you make it longer, then it will keep the radio keyed to
finish the data even if you stop talking.  If you keep the data too
short, D-RATS will send it in the first part of your conversation and
then expect to be hearing back about the status of the block while
you're finishing the voice part.  Since I have no reliable way of
telling when you've got the radio keyed for voice, it's nearly
impossible for D-RATS to know what you're doing.  Since I can't tell if
you're talking with voice, I also can't tell the difference between you
talking on the voice channel, and a packet getting lost due to interference.

As far as intermixing voice and data, it's generally a bad idea.  It
will be much more efficient if you just keep quiet and let the data
transfer happen at maximum speed and then go back to talking when it is
done.
