Fat Shark Headset

The headset has now arrived, and it should allow us to receive a live view from the 'copter as it flies. Eventually this will help us determine whether the RF comb generator is correctly pointing at the MWA tile beam while we make our measurements. Very experienced pilots use these headsets while actually piloting, but I am very wary of becoming disoriented, particularly in that I would not be sure of my peripheral vision.

Irritatingly, we do not have the correct attachment to charge the battery for the headset; apparently we need to go to Jaycar to buy the right adapter.

Also, the goggles do not receive directly from the 5.8GHz transmitter onboard the 'copter. I suspect this is because they are not in the same format; they appear to be American and are likely using NTSC, while the transmitter appears to be European, and is likely using PAL. This makes using the whole set-up extra-bulky, as we have to carry around the receiver and the enormous lead-acid battery we're currently using to power it, instead of just the goggles, screw-on antenna, and LiPo battery, not to mention connect the goggles to the receiver using a cable instead of just wearing them. This is an extra point of failure and I'm not very happy about it. I've contacted Aerobot, but I'm still waiting for a reply about the receiver battery.

The set-up may be due to broadcasting regulations on amateur transmissions at 5.8GHz. So the signal is too weak to receive from the Fat Shark headset. But since the picture is so bad, I can't tell whether it's the transmitter, receiver, or the headset.
