Re: NOAA warning for rf communications
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

This will not likely affect point-to-point line-of-site communications above 50Mhz.
