Hi does anyone have the single link inter face?   If so can you tell me what the
knobs are?  When I had someone help me hook it up I did not think to ask them to
tell me what the knobs are.  Right now I can not get the echo link to transmit so
it will go to my radio.  Also where can I go to adjust the mike settings for echo
link?  I can hear on echo link but when I transmit witht he computer all I hear is
a carrier and not my voice when I turn the speaker all the way up.
