Because I now have both the TCS-12 and TCS-10 Transmitter and Receivers in the exhibit, I was wondering what type headsets and microphones were used on the boats. I could not locate any photos to try and see what was used, so just putting it out there. Did they also use the Morse Code Key...............

Hi Frank,
I have this photo showing RM2/c Lou Rosso on Higgins PT243 talking on the TCS Radio. I heard they used the Code Key or the Microphone depending on the situation. I am posting the various headsets and mics we have on display aboard PT658. Jerry

Jerry thanks so much Buddy, those photos show in my estimation, that they used what was available and or comfortable ( as far as the headset) so it seems that if I make a purchase in what I have seen so far, my systems will be correct. I now need to find the cables to hook up transmitter and receiver................GREAT PHOTOS. If I remember, that microphone was also used in aircraft as well.

Frank,
I just discovered the proper name for that mic is a US Army Signal Corps Model T-17. However I also found another Navy Specific mic called a RS-38. Here is some stuff from aafradio.org about the RS-38

Naturally, the Navy couldn't use a Signal Corps microphone like the T-17 because it might contaminate their salty tradition, so they used what has become an incredibly long lived design called the RS-38, or in Navy-speak, the NAF 213264-6... with an NAF 212938-1 plug on the end. There was essentially no difference between the Navy plug and the PL-68 (like the one on the T-17 mic) except at the base of the shaft where it entered the wiring end, there is a .303" diameter by .093" ferrule added there to provide a salt spray baffle. A matching recess in the phone jack created a trap to resist spray in shipboard installations. At the same time, absence of the recess did no harm to operation in those equipments that had a more protected environment. It is possible to purchase a new RS-38 style mike with an updated dynamic or electret element even today, though they aren't made in the US anymore.

There were two different types of microphone hangers produced for this microphone. The one on the right has an irritating habit of scratching your new/old -38 unless you polish the sharp edges with a rubberized abrasive wheel, so use it with care.

Jerry, thanks so much. I have seen the R-38 at several military shows, but never bought them. Now that I could use one, the shows around here are over. I will keep my eye out for one, or may just purchase the one you have in your original photos, who would know, or complain, right. As pieces used for display, they will look great no matter which one I use, but your information was very helpful..........
