Current and predicted communications
conditions
- 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
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.
