Dear Listers,

 I'm needing the above subject info to scout-out the  reason my MX11 VHF cannot be heard loud and clear.  It's the same radio as  the Narco Com11 so they say.

  

 The radio transmissions are received "loud and  clear".  

  

 The intercom is crystal clear front and back  seats.  

  

 Radio checks reveal "you're loud and clear"  but they sound like they are coming through a mile long pipe  ... clear but very weak.  

  

 The Avionics Place at Rockford airport is getting  good response on their bench with their test equipment for  both xmit/receive.  

  

 The problem is in the aircraft wiring  somewhere.  

  

 Any ideas, hunches, experiences that solved such a  problem?

  

 Can anyone email an extract of the install  manual?

 My thanks to all on this List,

 Jerry

A.J., did you send the pinouts under separate cover?  I wasn’t able to find the file or a link in your response.  I have a similar problem with the MX11 and a PS Engineering 1000 intercom.  The intercom is crystal clear.  I can hear everyone talking to me.  My transmissions are unreadable.  A version of the pinout diagram found on the web has a hand written comment about a resistor and capacitor mod required to the radio’s “computer board”.  Is this true?  If so, does anyone have any more information on it?  Jerry, any luck with yours yet?

Gregg C. ...

 I finally got to the bottom of my MX-11 trouble.  There  was a shield wire shorting out the conductor bringing com audio in .... so I was  getting out OK but hearing nothing from the radio receiver.  

 I'm sorry my first expanation was unreadable because of the  broken English/French gibberish ... that came from my spell checker somehow, so  I don't use that part of email until it's fixed.  

 Did you find the trouble with your MX-11?

 Regards,

 Jerry

Thanks for your response Jerry.  Haven’t found the problem yet because I converted it back to the portable config to fly cross country last week.  It is coming down to one of three wires and I’ll check the ground and shield circuit paths this weekend.  Appreciate you passing along your troubleshooting experience.  - Gregg
