This looks like a great project and it looks like it is coming along well. One thing I have always wanted to do is mod a comms pack so I can switch between comms and a PFL feed fed from the headphone out of a desk. So far as I know there is nothing currently available that does this. I know I could us an aux in on a base station but thats not really what I'm after. Would this be achievable with the design? I was thinking just a toggle switch in-line before the headset out. Would this un-termination have any negative effects for the rest of the comms ring? Alternatively, if anyone is aware of a product that does this I'd be interested to know. Many thanks Mark
