MID-CONTINENT CDI for NORTHSTAR GPS and/or LORAN - 12/14V and 24/28V

This is a Mid-Continent MD40-08L lighted CDI, originally intended for a Northstar M1 Loran, but the dial face has been relabeled for Northstar GPS.  It was installed and used with a Northstar M3 Approach GPS, and was working very well when removed with the GPS several months ago.

Northstar Loran receivers and Northstar GPS receivers all provide the same signal outputs to drive the CDI needle and have the same signal outputs for the on/off flag and the various annunciator lights, so this unit will work with the Northstar M3 Approach GPS, and also with the Northstar M60 GPS, the Northstar M600 GPS, and the Northstar M2 GPS, although the annunciator labels may be different. It may work with other brands including Garmin, but I do not know that for sure.

This indicator fits in a standard 2-1/4” panel cutout and will operate with 12/14 VDC or 24/28VDC. However, the lighting (if wired up) requires 12-14 volts only and may be dimmed.
