David, I suggest a momentary switch (push button) located somewhere convenient (e.g. on the headset or on a control joystick that your hand is on anyway) for PTT, and then a full switch somewhere else that you can toggle to force full duplex (continuous transmission). You might also find that there are physical switches available that can perform both functions, where it acts like a pushbutton when you only press it e.g. halfway down, but will latch if you push it all the way.<br><br>Sean<br><br>-------- Original Message --------<br>On Nov. 20, 2020, 10:23, David Colombo via Personal_Submersibles < personal_submersibles@psubs.org> wrote:<blockquote class="protonmail_quote"><br><div dir="ltr"><div>Alec, in the SeaQuestor, I figured that I would have the same problem with the separation of the pilot and passenger, so I am adapting a wireless headset used by motorcycle riders so that we can communicate while wearing the headsets, and I can still hear topside. I am adding a switch that cuts the boom mic to the topside while letting me speak to the passenger. If topside calls, flip the switch and the boom mic becomes active to the comms. At least that is the plan anyway.</div><div><br></div><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div>Best Regards,<br>David Colombo<br><img src="http://static.squarespace.com/static/533310a9e4b0fba62008a464/t/5339c1f2e4b041bac4e25d1b/1396294132055/?format=500w" width="200" height="110"><br>804 College Ave<br>Santa Rosa, CA. 95404<br>(707) 536-1424<br><a href="http://www.SeaQuestor.com" target="_blank">www.SeaQuestor.com</a><br><br></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Nov 20, 2020 at 8:21 AM Alec Smyth via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">My gripe with the headset is that in a 2 person, if you have the headset on you can’t chat with the crew, and if you take it off for that reason you can’t hear when the surface calls. I use a little adapter box that has input from a hand mike, and output to a tiny Radio Shack amp about the size of a pack of cigarettes. A similar adapter is used on the surface, but in that case input and output are to ordinary headset with boom mic. I use SSB-2010 units both in the sub and on the surface.<div><br></div><div>Best,</div><div>Alec<br><br><div dir="ltr"><br></div><div dir="ltr"><br><blockquote type="cite">On Nov 20, 2020, at 8:55 AM, Jon Wallace via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><div style="font-family:times new roman,new york,times,serif;font-size:16px"><div></div>
