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.  

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:
     _http://webs.lanset.com/wa8lmf/miscinfo_   

Look for the link to the file  "  KenMic_RX_Audio.PDF  " .  

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.
