You become use to the number of turns per 25Khz or so, and more often 
than not the band edges are identified by a commercial station, but I 
have used more successfully than anything at all b4 talking readouts 
a 25Khz crystal calibrator which generates carriers every 25Khz. You 
count the numbers E.G. 7.025, 7.050, 7.075, 7.100, 7.125, etc. etc. 
and you are then aware of where you can transmit or not.
