I'm afraid those questions are outside my pay grade!
If you are near one of the hamfests that Flex Radio will be
attending in the next few months, you might pose those
questions to them.
Or you could post them on their Facebook page and get
an answer there. Several of their programmers and engineers are on there
and "should" be able to give you an answer. Also, you might ask
on the Flex Users Net on 14.329 +- each Sunday at 1pm CST.
Several of their people are there as well. And the net can also be heard on
Echolink (directions are on Flex Radio's website).
