An odd scale on the radio

 

It was nice to see the sort of radio dial I was used to as a child. In those days, VHF used to be synonymous with FM. It's true that VHF has frequencies that are 1000x those of medium wave, but the main difference is the modulation method. Medium and Long Wave were both AM (amplitude modulation), where the height of the wave is changed to carry the signal. FM is where the frequency is shifted up and down around the carrier frequency to encode the sound. The LOG SCALE  label is confusing. Log would mean that each mark would be, say, 10x more than the last mark but for the scales above, that is clearly not the case. Looks linear to me.
