Current and
predicted communications conditions
- MUF
- Red -
high frequencies (HF) are unavailable (>22 MHz)
- Yellow
- lowest usable frequency (LUF) and maximum usable frequency
(MUF) range is 15-22 MHz
- Green
- LUF-MUF range is 8-15 MHz
- Blue
- LUF-MUF range is 3-8 MHz
- foF2
- Red -
high frequencies (HF) are unavailable (>11 MHz)
- Yellow
- lowest usable frequency (LUF) and maximum usable frequency
(MUF) range is 8-11 MHz
- Green
- LUF-MUF range is 5-8 MHz
- Blue
- LUF-MUF range is 3-5 MHz
If a communication
link is not working at these frequencies, there is a higher probability
of malfunctioning equipment and/or jamming as a cause for outage.
