Old ADF
Wondering if I can get some help here!
A Cessna aircraft I'm now flying has a very old ADF (1969) - it's one with a big dial in the middle. I've seen one in a PA-28 too.
Being used to a "normal" ADF with a digital output I'm a little perplexed by this device and wondering if anyone knows how to translate frequencies in the chart onto the ADF? It seems to have various subscales and a selector for decimal point position.
