Brief description of the issue:
DC-3: Radio Compass not working
Provide Screenshot(s)/video(s) of the issue encountered:
Detailed steps to reproduce the issue encountered:
Assuming Radio Compass uses VOR 1 or 2 as input: Tune both radios to nearby VOR. In this example both NAV radios tuned to same VOR. Observe bearing of VOR from aircraft on VFR Map as reference. Adjust ADF to present heading (080deg in the attachment) to show bearing of VOR (045deg in the attachment, looks about right on map). Check radio compass which shows the wrong bearing (090deg). Use skew mode to rotate aircraft on the ground - needle on radio compass does not move - it should move with the rotation of aircraft.
PC specs and/or peripheral set up if relevant:

Umm, the radio compass displays ADF information. I have found that, if I tune the ADF to the appropriate NDB frequency, the radio compass behaves as expected. Have I missed something?

Thank you - I marked your post as being the Solution… I had hoped the radio compass was linked to VORs and not beacons since there are so few low frequency beacons remaining. And they didn’t label it as ADF which added to my confusion.

Cheers. Radio compasses existed long before any of the “normal” navaids became common. As far as I
know it could actually be used on any radio signal within the operational frequency range of the system. ADF and VOR have always been mutually exclusive due to both the frequency ranges used (kHz range for NDB’s, MHz for VOR), as well as NDB’s being purely an omnidirectional, unmodulated signal while VOR’s have information in the signal that indicates the direction from the station.
NDB’s were simpler, cheaper and more ubiquitous but VOR’s were obviously more useful and “user friendly”. And now we are in the situation that NDB’s are slowly but surely becoming extinct.
As for fractional NDB frequencies: I recall that historically, real transmitters and receivers were not that exact, so fractional frequencies were not a problem. I know for sure that one of the closest NDB’s to my home base of Cape Town in South Africa was the SP NDB. This still exists and was always nominally at 222.5. kHz. The ADF in the Cessna 210 that I owned at that time could not tune fractions but it was still able to pick up the NDB OK.
