 Executive summary

Essentially when on the ground 1.3 vtx range is crap.

When in the air we had excellent video (150m altitude 4km range). We need to be able to receive video when landing on far away landing pads (otherwise how do we land on them?).

There was also large interference when a manned aircraft came overhead leading to concerns about us requiring more filtering or something.

From Anni we were videoing at 1280 MHz.

Actionable Recommendation

Reasoning

Look into a spectrum analyzer (via sponsorship)

We want to see ambient noise on 1280Mhz and also see if there are other options that appear better.

Try a different Vtx & Vrx & Atennas

Seems relatively easy and might just do the trick. Possibly ESD events have slightly damaged these components as well.

Nothing Further

It’s a lot of research and effort that's not really worth the time in my opinion. Worst case we fly comp on 5.8 Ghz and it’s okay ?
