Idea Box: Second Experiment

The most local beacon for me is OZ7IGY, about 30km away.
Now I am curious how little effort it takes to receive it.
The idea is starting to use a PLL LNB without a dish, just the built-in feed horn.
Because the beacon is beyond line-of-sight, the propagation will be tropospheric scatter, so the signals may be too weak to hear, but the experiment should be done. Next step would be a 15-20dBi horn antenna, then a small dish, 30cm or so.

It would be fun, however, if the beacon is audible with just the LNB, even if it is not constantly audible. This may be an opportunity to try the PI4 mode for beacon detection.
