Im looking into some VHF radios for our venue staff. Going between these two makes: RDV 2020 On-Site Two-Way Radio - Motorola USA Blackbox Radios But choosing is not my only problem. If we end up purchasing these VHF's I would like to have a base station in the booth just because alot of times I am in the booth and need to get ahold of my staff. Does anyone know, or can give me some facts: I'm wondering with a base station in the booth with sound equipment will create a buzz in teh equipment or if I was to have a handheld radio in the booth with me that I would use would it create any interference or humming? Thanks!
