The FCC recently granted two companies experimental licenses to use
High Frequency bands for data communications at far greater bandwidths
and data rates than have been used by amateur radio operators in the
USA.
Writing in TV Technology, Doug Lung says the license application by
MITRE is to use HF modes with emission designators of 5K00Q3N,
500KD7D, 500Q3N, 500W7D, 1M00D7D, 1M00Q3N and 1M00D7W. 1M00 has a
necessary bandwidth of 1 MHz.
The company hopes to achieve reliable HF communications at a data rate
between 1 and 4 bits per Hertz per second. MITRE said it will develop
a 100 kHz bandwidth waveform that can achieve approximately 256 kbps
with forward error-correction coding. More is at tinyurl.com/nprsuje
