Sorry if this has been mentioned before.I have just been checking some UK SIDs one of which uses an NDB with a frequency of 433.5 but see that the 737NG ADF will not tune in decimal values, unless I have missed something.I admit I have not noticed NDBs use anything other than 'full' frequencies but since I have found one I'll bet there are others :-)Is this a known 'problem' or have I missed a setting in FS9?RgdsDave

Use the A key 4 times to get to the decimal part then +/- to set in .25 increments.Ray

Thanks Ray.Dave

Despite my 'Thanks'post Ray it is not working for me.The manual states that the outer ring sets the hundreds, the middle ring sets the tens and the inner ring sets the ones and tenths but there are no click points showing round the rings. The only click points I can find are above and below the ADF display which do in fact change the displayed numbers up and down. However there are normally only 3 numbers showing but if I increase the 'hundreds' I can get 4 digits showing but they are not tenths.I have tried pressing 'A' (select ADF, according to the assignments) 4 times but that still does not give me a decimal figure.Any more suggestions?Also does the ND not display NDBs?TIADave
