'm the last hardware developer between all of the groups in the lab, but I've been keeping myself busy. Too busy, that's why I'm looking for help. We need to connect our new device (that I'm building) to the existing NAS PTT connection between the voice switch and voice radios. That sounds simple, but it's a nightmare. When I started I thought this was going to be just some kind of standard well defined connection port. Wrong. There are 4 different flavors of voice switches, 4 different flavors of voice radios, no standard connection definitions and some sites have remote radio connections via Channel Banks or RCE's and most of the documentation is nonexistent or not available. I need some kind of translation device to feed my device for PTT connections that are using voltage keying or E&M signalling and anything else that shows up. We are intercepting the transmit control signal and we can never keep the radio from transmitting. I've been exploring it, but it's too much while making the main hardware in the time frame given.

//==============================

Ideally, I'd like to get some kind of freelance EE, or retired persons that can do this short term, 4-6months, but other arrangements may be considered. They have to be able to start immediately.
