Hello. I've wondered for a while now why the bands are named what they are. For instance, we have the 20m band, but most of the frequencies are actually 21 meters. 300 / 14 = 21.4 meters, and 300 / 14.35 = 20.9 meters Likewise, 15 meters are actually all in the 14 meter segment. Does anyone have some history on why they are named what they are? Thanks, Jason |

At one time there was an intentional harmonic relationship between the bands, so harmonics generated by hams would affect hams, and not other services--so it made sense to call the bands 80/40/20/10 meters. When we first got the 15 meter band in 1947, decades after the other bands were allocated, you could find references to the it being called 14 meters--but I think this got changed to avoid confusion with the 14MHz band.

You've got to call them something! The worst band is "80 M". 80 Meters is 3.75 MHz, but the band really ranges from 85.7 to 75 Meters. Even so, the 160/80/40/20/10 names still hang together pretty well. Microwave bands are worse. Quick, which is higher - C band, K band, L band, or X band? My problem is remembering all the band and sub-band edge frequencies. The "new" WARC bands are especially odd, not to mention the 60 M channels. 73 Martin AA6E |
