New internet path A new path to the internet was added, it gives the MWX the opportunity to use both the LZ and J's connection in case the other fails.
MWX antenna was realigned so both (35 degrees apart) ground based stations are within reception.
LZ turned out to be unreliable, MWX antenna should just be aligned to J.

Cameras
Update 6. Jan 2019:
The cameras can withstand the excruciating heat, and high RH (over 100%RH) but not the mechanical shaking of the Windsockmast. During strong winds, the windosck causes very hard shocks which somehow crash the cameras.
Either the windsock needs to be guy-wired, or we need to use cameras which can withstand higher G-forces (expensive).

Not implemented yet as of 6. Jan 2019...One Sharx SCNC3606 watching the BB (VGA).

Turned out not to be an issue: Cameras might smear too much because of long shutter exposure. Cameras with short shutter time are expensive.
Cameras are sending a snapshot each minute to FTP.
(old: Cameras will be polled by CSS or LZ. They can be set to send snapshots etc.)

while solar charging: The 12V input to the DC/DC converter had 60mV (pp) noise. The 5V output of same DC/DC converter had 300uV noise (while solar charging and also switching to (a lower voltage) DC power supply). The 5V might be a bit more noisy at the pins of the Mega, but surely way below the 4.8mV 1 bit resolution of the ADC.
