<DIV>Hi Duane -</DIV>
<DIV> </DIV>
<DIV>When I first got my Hermes I ran comparisons between xmit audio fed
into the mic jack vs. Line In. I recorded and played back using a
second SDR. I couldn't hear any difference. However, I'm using an
auxiliary audio rack with line level outputs and so wound up with Line In fed
into the 25-pin connector. It works fine. But either way sounds the
same....</DIV>

<TD vAlign=top><BR>For those who have or are using the line level inputs
for the Penelope and/or the Hermes is it worth the extra effort in terms
of having better quality TX audio?<BR><BR>I like the idea of using line
level mic audio inputs on these boards, but am questioning if it is
worth the extra effort to make up the cabling and connectors to
interface with them vs. using the comparatively easier to work with
3.5mm mic inputs.<BR><BR>I'm in the process of re-working all of my mic
signal handling throughout the entire shack and am striving to use
balanced line levels throughout the system for as much of it as I can,
and then only transitioning to unbalanced and/or mic level inputs to the
individual radios as necessary. I will be using W2IHY IBox interfaces
for each radio.<BR><BR>Duane<BR>N9DG<BR><BR></TD></TR></TBODY></TABLE>
