Narco MK12D Repair

[Caribbean Aviator]

Hello everyone. I have a Narco MK12D radio that is having issues. My radio reception  is very poor and with low volume. I can hardly understand the ATIS even when 500 ft from the tower. The antenna was checked and found to be ok. I’m looking for recommendations on a good shop that could inspect the radio and repair as necessary. I realize that the Narco is a mediocre radio but I would like to keep it going until next summer when I plan to do a full panel upgrade. I’m in South Florida but don’t mind shipping it somewhere else if that improves the odds of getting it repaired correctly. Any help is greatly appreciated.

The D is the last version of radios Narco ever built...

It probably isn’t as bad as the other crud they built...

They closed up their shop right after the D came out... they didn’t succeed with a bridge to The digital (D) age...

You can throw money at it... because you are describing poor antenna connections...

Or buy a new radio and install a new antenna with new connections and ground plane....

Got a radio shop you like to work with?

If you want to see what else is available... there are pre-flown radios around here... including GTNs...

Best regards,

I’ve got a MK12D that has been more reliable than the brand G sitting above it.  They are actually quite good and robust.  Try these guys:  http://aircraftandavionics.com/

I had these guys work on my 12D+. I believe when Narco went belly up, they bought out a large portion of the service inventory.

Might try these guys Gulf Avionics in Harlingen, they are under new ownership but the original owner fixed my Narco and was fair priced

Guys. Thank you for all the feedback. I have added the shops mentioned above to my list for future reference.  Also I found a shop in Arizona called Marks Avionics that also works on old Narco radios. I spoke with the owner and he told me that he has a very extensive inventory of parts for the Mark 12. Long story short my local avionics guy did some research and found out that some weldings in a particular board are known to cause the problem I was having. While he has no parts for my radio he asked me to allow him to take a look at it before sending it somewhere else. He did a detailed inspection and found a couple of weak welding connections in one of the boards. He cleaned them up and re soldered the affected ones. The radio is working great now so hopefully I won’t have any more issues for a while.
