[Vk5-wx-sonde] Upcoming RS41-SGM launches

Tue May 21 03:19:47 PDT 2019

OK, I've now merged the changes into the 'main'
projecthorus/radiosonde_auto_rx testing branch.

To use this branch you need to (within radiosonde_auto_rx) run:
git checkout testing
git pull

and then do the usual update steps (rebuild the binaries with ./build.sh,
etc).

The launches from Pt Wakefield will be on 400.2, 402.2, and (hopefully not
for much longer) 404.2. The message has been passed on that 404.2 is not a
good place to transmit, if they continue to transmit there I'll be calling
the Defence Spectrum Office. I suggested 401.2 MHz instead.

Apparently tomorrow will be the last set of launches for a few weeks.
Predictions have them landing out near Stonefield.
