Hi,
No problem, you can have as many people as you want using the station, but obviously not at the same time. The group I am with has about 12 people using it that way. We have a logbook on Google Docs to coordinate who is using it and when.
We do not have a panel at the radio site. If one must use the rig, they need to use the computer or bring a panel with them.
