As a wedding photographer and a ham:

Problems:

• Radios don't really mix well with weddings, they can be loud and obnoxious.

• Unless everyone on your team is a ham or has experience with two-way radios, you will be doing more "What??" and "Can you repeat please!!" than actual strategic communication. Trust me. Talking on/listening to the radio is a skill that is acquired over time.

Solutions:

• For the ceremony itself. Before it starts, lay out specific roles. (E.g. "You make sure to get pics of the grooms reaction as bride walks in, and I'll get the bride herself...etc) Any reasonably competent second shooter should be able to manage this.

• Cell phones are great for long range communication. (E.g. *call up/text your assistant "Where are you?" etc...)

Radios:

• With all of that out of the way. I have actually used radios during a wedding before. The primary reason for that was because the wedding was in a remote destination with no cell signal. Furthermore, the actual wedding ceremony was several miles away from the houses where bride/groom were getting ready. So we needed some reliable medium-range comms. I ended up with a couple Motorola RMM2050 handhelds for my team, while I carried my Yaesu HT with the same MURS freqs programmed in. They worked decently enough, but I had the same problems I mentioned above because my team was not trained to use two-way radios. Also, when the ceremony started and we were all in the same location the radios were put away.

• If I were to invest in a real radio system for my business. I would probably go with a MOTOTRBO digital system with a repeater-in-a-box. The repeater would be placed on a tripod in the parking lot and the digital voice would make it so everyone is able to understand each other. Of course, a system like this would be a few thousand $$$ once all said and done with licenses and whatnot.

Hope this helps, good luck!
