Hey all. I may be mistaken as to where this should go, but I'm looking for a low cost PTT for a HT1550XLS to interface between my radio and my civ comm equipped HGU-56/P Flight Helmet. I'm a volunteer with the local sheriff's office for SAR, and totally self equipped, so funds are an important factor. (3 kids and 4th on the way - discretionary funds are tight.) I do ground search, technical rescue, switftwater rescue and heli-rescue. Bonus points if it is also compatible with a peltor headset.

Any direction would be greatly appreciated.
