Here's my question:



After doing a battery charge, I discovered to my dissapointment that the

DME head serving my Narco MK 12D is not working. The VOR tracking is

working, but the DME LEDs seem to be out. Of course, I can't tell if the

DME is functional, but not displaying. Anyone have a similar experience? I

know that some Narco elements have a sacrificial part (diode??)  that is

supposed to prevent unit damage in the event of a voltage spike.



Please, no Narco-negative comments. The Garmin Fairy has not come to my

home, and it's not in his/her flight path (that I know of). I left the DME

on during the charging event. It's my fault. Any suggestions/Help are

welcome.



Any recommendations on a radio shop in Md. or Northern VA are also welcome.

It would help to have a part number or two. I think the last DME that Narco made was the DME195 which is a fairly large blue box hidden somewhere. I have seen those beasts channeled by a MK12D but they have a readout that is a rectangle about 1 inch high and 3 inches wide. The lamps are not LED's but rather seven-segment incandescent lamps.



Can you listen to the DME code that is sent out every minute? That will tell you something about what's working and what is not.
