== Current Status ===
* We have some parts but we need but quite a lot of stuff needs to be bought, built or fixed (see Kit below).
* We need to have proper discussion with other interested parties.
* We need to come up with a final design of what will go on the antenna array and how it will be organised.
* We need to at least speak provisional permission for the antenna array to be erected ,so we are aware of any additional things we need to consider.

=== Sensible ===
=== Sensible ===
** 23cm at bottom
** SURGE FM broadcast above 23cm antenna (we'd help them get back on the air)
** HF antenna of some sort
** 70cm+2cm with dual-band rotator
** triband 2m/70cm/other vertical antenna on top of dual-band rotator


=== Varying levels of silliness ===
* 23cm on spur
** Large SUWS flag on top concealing a loop antenna
* radio telescope (astrosoc)
** Ask SUSU TV if they're interested (short-range camera links)
* monitoring node (temp/wind ect)
** SOWN Wi-Fi by coordinates
