Add support for "Low Band" #6

A number of transmitters have added support for eight new channels that are in a frequency range just below the normal 5.8 GHz band. This adds the possibility to use twice as many channels at the same time without interference, so it is is a good thing. The not so good aspect is that transmission on this new "Low Band" is illegal in most countries. Reception is however never illegal, so it would be a good idea to implement support for low band channels in the Cyclops googles.

The "Low Band" frequencies are outside of the stated specifications for the receiver chip in the Cyclops (a RichWave RTC6715). There is however no mechanism in place that blocks selection of the somewhat lower channels. I will make a practical test of the viability of tuning the receiver chip to the "Low Band" frequencies. If success full, I will add support for all 48 channels as a standard feature.

v2.2 is release. I has got full support for the new low band centered around 5.5 GHz
