Before I explain this diagram, I would like to give the credit that this Mnemonics is made possible courtesy of PERCdc Review Center. I merely improved and added my own stuff. This is to somehow enlighten the memory load of reviewees especially in EST. I guarantee that once you are familiar with this, you can easily recall this until the day of the board exam or even beyond that!.

This mnemonic touches several fundamental topics of EST and is very much essential because who knows there might appear a question or two from this one. (every Point matters).

Ok now for the fun Part. The Mnemonics. The letters with the green highlights are the 1st letters of the different ITU RF designations. (Ref: Page 17, Tomasi). In order for easy recalling of the different bands simply use this mnemonic : Every Very Very Loving Mom Has Very Ugly Son Except I.
* Please take note that Voice Comes First before VLF*

Now In order for you to know the frequency just remember this Mnemonic: VHS at  3:30, kasi Ma Galing.
*Take note that the V in there stands fot Very Low Frequency, the kasi Ma Galing corresponds to the frequency in kilohertz,megahertz and gigahertz respectively. The 3:30 signifies the frequency range for these three.

Moving on, We will proceed to Wave Propagation Topic and its relationship with the spectrum. In order for you to easily recall what wave describes what, simply familiarize yourself with the illustration and the apply this Mnemonic: My Kilikili Has D Most Decent C Mill.

And then as a final note: Just Remember SKY is High Frequeny, Frequencies below Sky are Ground and above the Sky is Space. Refer to the figure.

Once again. This diagram would not be possible without the mnemonics I've learned from PERCdc.
