Hi Stefan,

 

the 40 meter band is from 7.0MHz (=3D 42.86m) to 7.2 (=3D 41.67m). = The 'error' is 7,2% at the lower band end and 4.2% at the upper band end.

For 20m it is about the same: the band is 14.00-14.35MHz while 20m =3D 1= 5MHz.

In fact, on HF there are only 2 bands where the wavelength is is named a= fter is within the band (160m and 80m).

 

If we call 472-479kHz (=3D 635,6m - 626.3m) the 600m band the 'erro= r' is 5.9% at the lower band end and 4.4% at the upper band end.

 

So for me there is no problem in going for a round number, as we do for = most other bands.

 

73, Rik  ON7YD - OR7T

Lambda =3D c / f =3D (299792458*m/s) / (477000*1/s) =3D 628.496m ~ 630m.
