[drats_users] DRATS questions

[Ted Wrobel]

The D-Star data stream has pre-defined voice and data portions. Leaving out
voice does not make more data space available, so transmit times will be the
same.
 
The voice and data portions of the available bandwidth are roughly equal.

Don,
 
I am not sure if the following is what you are asking but you can send files
using dstar and at the same time as you are talking if you wish.  We have
done that several times.  What I don't know is if the file takes longer than
when one is talking what  happens. I  assume the repeater stays up unless
timed out  but the person on the other  end wound not hear any voice but
should  have some indication that the repeater was still busy.  If you were
using dstar simplex then timing out would of course not be a problem.
 
The dstar voice occupies about 6k bw and d-rats about 1.1 k BW and they
coexist by some protocol which I don't know.
 
I hope this helps some.  We have a dstar repeater on 25B usually but we can
put it on any node so if you want to try some file  transfers using rf dstar
and coupled via the internet I would be glad to run some experiments on
reflector  15C which is a data reflector. I can change our dstar repeater to
reflector 15C anytime so if anyone wants to work via reflector 15C rf I
would be glad  to give  it a try.

1) Can D-RATS use a D-STAR RF link and Files to transfer files via the DRATS
ftp?  One pdf I read said that the D-STAR RF link only works for Chat and
QST.
2) Is there an iPad version of D-RATS?
