On my (very) old handheld radio, Short Wave is represented by the letter "K". As opposed to "U" for FM (The U standing for Ultra-High Frequency) and "MW" for Medium Wave. Can anyone tell me why this is? I can't find the answer on the internet and can't seem to figure it out for myself.

The Radio Regulations of the International Telecommunication Union allow amateur radio and amateur satellite operations in the frequency range 24.000 GHz to 24.250 GHz, which is known as the 1.2-centimeter band. It is also referred to as the K band by AMSAT.
