[App_rpt-users] Audio Clipping with IAXRPT / Web Transceiver Client

[Keith Goobie]

Hi Bryan

Thanks for the input on the limitations of some USB hubs.  I have seen that
before on another project.  In some cases I went back to plain old serial
ports, but that is not possible here.

I will keep my eyes open for error messaging in that regard.

One suggestion, I did receive was to remove the rxboost and I have done
that.  I think it has helped and I am monitoring it.  This would suggest
that the problem was amplitude related and not jitter where I was trying to
point myself.

There will be more to follow.

Again thanks to all for their feedback.

Keith
