I can tune the DME station with my hardware now, but nothing happens, no DME reading. When I tune the station by rotating the dials with my mouse I get the right DME reading. It seems I have to bind something more. Anyone ideas?

Unless I'm missing something, I anticipated this coming up, so I added an intermedia tuning position for each 500 khz, allowing you to tune 113.35 Mhz.

Damn, I should've known haha. 👌

It will show the DME of the NAV 1 station.
Hope that helps.

On the Narco UDI-4 DME, you cannot tune a second decimal digit because the unit only supports 100 kHz (0.1 MHz) frequency steps.
The Narco UDI-4 was engineered in the early 1960s when the standard civil aviation navigation channel spacing was 100 kHz.
It is designed to match legacy VHF Omnidirectional Range (VOR) frequencies from 108.0 MHz to 117.9 MHz.
The mechanical channel display on the face of the unit only features three major numbers and one single decimal digit (e.g., 114.3).
