2 Way radio for events

Afternoon all,

On the hunt for a little information which may be obvious to the more experienced. We will having a charity event in a few months time with volunteer stewards using radios but for various complicated reasons there will be several other groups (first aiders, security etc) on different frequencies and in the middle of this will be me, trying to stay in contact with them all. Is there an easy way to do this - a unit which can pick up and reply to multiple frequencies- or do I literally need a radio for each group?:eek:

I think the best solution would be to rent the radios for everyone so they will work together.

Is there a local amateur radio group that might be willing to furnish communications for you on a volunteer basis? In the US a lot of clubs and other amateur radio organizations do this as a matter of routine.
