Well, this is more than you really wanted to know, but.... ELV Exremely Low dc - 3khz VLF Very Low Freq 3khz - 30khz LF Low Frequency 30khz - 300Khz MF Medium 300Khz - 3Mhz HF High 3mhz-30mhz VHF Very High 30mhz-300mhz UHF Ultra High 300-3Ghz SHF Super High 3Ghz - 30 Ghz EHF Extremely High 30Ghz - 300Ghz Different folks put the breaks at slightly different places (the.g. the amatuer radio community puts the hf/vhf break @ 50Mhz and the MF/HF break @ 1.8Khz. And, as a side note, I can't find the URL, but the US Cong is talking about pulling all the funding for the NASA space weather programs. Would mean less/no warning of this sort of stuff. We now return you to our regularly scheduled off topic discussions Komrade Owen DeLong wrote:
This will not likely affect point-to-point line-of-site communications above 50Mhz. It will likely affect non-terrestrial communications and HF communications depending on ionospheric reflection.

"High frequency communications"?
We *are* talking about multi-GHz frequencies here.
