The SiLOS-on-the-Air program started in 2021. Another reason for getting out and about and visiting those interesting silos with murals. The silo art trail and calendar are a nice complement to working silos.
Generally, silos are not radio friendly because they are often co-located with high RF noise sources. But the rules permit a 1km radius to work in so you can scout a position which mitigates this interference. Sometimes it works, sometimes not so much.
There are several Silos in my “local” area, Cardiff, Kooragang, Carrington, Moscheto Island and Stroud.
