Working Nets

Nets are a great chance to give club members a go at the art of net control. Otherwise known as herding cats. In some situations where everyone can hear each other, establishing a ‘circular order’ or ‘firing order’ (for the petrol heads amongst us) can work well where one member passes transmission to the next with the net chair handling things if someone forgets. Which is often.

The other net topology is a ‘star’ based system where the transmission is passed back to the net chair after each over from participants. This is better/essential if not everyone can hear each other.

If all else fails “throw it up in the air” also works towards the end of the net.

Listen, before transmitting, is always a good strategy to make sure you’ve got the channel and are not ‘doubling’ (transmitting at the same time as someone else).

A pen and paper (or electronic equivalent) to keep track of net members, firing order and points to comment on is recommended unless your memory is very good.
