DC-3 Nav dial

Is there any way to be able to actually read the DC-3's Nav dial so that a sim pilot can be confident with knowledge of its use while trying to fly from one VOR to another, and what about the ADF?
I have tried for many days to patiently click once [right or left] of the desired signal for its use and wait to hear the morse code verification, but once again I can not read the dials on the radio stack to know what frequencies I am trying to tune to and after several seconds I hear no audio. Yes, I have the audio dial turned ON and my external spkrs, as well.
Thanks to all that reply :)
