Howdy - I hope someone can help with an easy question.

I have an old T5600 dispatch console at my work. We only run 1 VHF channel.
We want to expand to have 2 dispatchers. Can we add a second desktop mic to our existing T5600 console? If not, what's the best route? Can anyone suggest a vendor?

I've inherited this problem, but no one has manuals. It's become a headache. Thanks in advance for any help. I really appreciate it.

Wire the mikes in parallel, but make sure the PTT on each mike switches its mike element off when released. - Jim
