90MHz or 90 MHz??

After nearly 40 years as a professional RF engineer you would think that I should know!! 

Should there be a space after the number before the kHz, MHz or GHz or not? Can either be used? I should try to use the correct format.

One thing is clear. Most engineers don't care!

According to NIST in the US there SHOULD be a space between value and units.
