<pre wrap="">OK,
I'm going to live with the crossovers. I corrected the spelling error on the second page and I reordered them so that what was the second page is now the first.
Additionally, I've saved it as a PDF so you folks can read it.
However, I just noticed the 'audio out' connector on the second page (TM-211A). I'm wondering if the 1/8" phone plug could be eliminated from the harness using it.
Check it out at <a class="moz-txt-link-freetext" href="http://www.wb4aej.com/APRS/APRS_Harness.pdf">http://www.wb4aej.com/APRS/APRS_Harness.pdf</a>.

The "receive audio" or "audio out" pin on Kenwood mic jacks has been on
some, but not all, Kenwood radios for decades. It is very
inconsistently implemented -- some radios have 50 millivolt
non-deemphasized non-squelched raw discriminator audio here, others
have higher level de-emphasized audio here and still others have actual
speaker audio affected by the volume control here. <br>
<br>
Since I like to take advantage of this contact for a "one-plug" hookup
for SSTV (especially for the Kenwood VC-H1 handheld SSTV device) and
packet, I have measured the type and level of audio available on the
mic jack for many Kenwood radios. On radios that didn't have any
connection here, I added it. The results of my findings are summarized
in a PDF document on my website at:<br>

Look for the link to the file " KenMic_RX_Audio.PDF " . <br>
<br>
As is usual for PDFs on-line, if you LEFT-click the link, the file
will try to open in your web browser, using Acrobat as a browser
plug-in (if Acrobat is installed on your system). A RIGHT click
will offer a choice to download the file for use off-line. <br>
