Content preview: Hello to all of the Decca Navigator experts out there... I have an unconverted Decca 5501 transmitter which is marked "Red" - I believe that is 112kHz - would like to run it on 73kHz. The tank coil reads about 80uH, can I just pad it down with more "C" to get to 73kHz or would that mess up the L/C ratio and thus lower the loaded "Q" ?
