[Elecraft] Line out

Hi again,

It's been a little while. I had to investigate this in order to be
completely comfortable with short circuiting the right channel with my mono
to stereo adapter. The schematic for the KIO3 module shows a 604 ohm
resistor in series with the output, so that puts this to rest. I could also
verify this with an ohm-meter. The schematic is a little misleading (the pdf
file) as it shows the same ground symbol on the secondary side of the
transformers as on the primary side. I have verified with my ohm-meter that
the line out is indeed completely floating with respect to the various
grounds found on the transceiver (such as the coax connectors). This is
good. I am assuming that some detail in the schematic has been lost in the
ORCAD to PDF conversion. (If these schematics are not created by ORCAD, I'll
eat my hat.)
