    I just taught myself how to produce this table from thin air. Didn't think I was still capable of this level of mnemonic recall! 😛

    A notepad showing the 6 key HF bands organized in a table showing the name, a mnemonic multiplier, then their start and end frequencies. The mnemonic multiplier works from the principle that the 40m band starts at 7MHz, and all other bands start at multiples of it. From there all other bands can be derived by multiplying 7 by the multipliers, and the only thing one really needs to memorize is that the band names start at 160m, then half each one to get the next (except 15m, single exception), and the end frequencies which don't really follow a rule so are the only thing you really need to recall.
