Squawkbox

I will soon be at KMSP in my Round Robin in Bush Ops.
When I arrive there I would like to comminicate with other pilots.
I believe to do this I need to run something like Squawkbox which I have.
Is this the suggested method ot are there any better programs?

Thanks Yoland. It is also many years since I have used Squawkbox. I am not even sure it still works.
I thought you might have something else in mind in Bush Ops when you mention contacting other members when close to one of he hubs.
