Hi Whipper.
Quadrifilar helix antenna plans

I use the following shareware software.

WxTrack to track the sats.

WxToImg for the decoding of the signals to images

Unfortunately I didnt pack the antenna when we bacame liveaboards, so need to build a new one. Last time it took around half a day to do, quite straightforward.

Dug out the rx2 receiver - that still works - typical ham, never did box it lol.. so need to build it into a small box.
