I just realized I gave bad advice to David about latching the PTT, because I wasn't thinking straight. SSB-2010, or in fact any acoustic unit, will be PTT only. Only 4-wire hardwire systems can run full duplex, so you never want to latch / switch your PTT in the sub to be always on, lest you not be able to receive any transmissions.<br><br>Sean<br><br>-------- Original Message --------<br>On Nov. 20, 2020, 19:36, Jon Wallace via Personal_Submersibles < personal_submersibles@psubs.org> wrote:<blockquote class="protonmail_quote"><br><html><head></head><body><div class="ydpec7213b0yahoo-style-wrap" style="font-family: times new roman, new york, times, serif; font-size: 16px;"><div></div>
<div dir="ltr" data-setdir="false">Alan, don't know, but I will certainly look into it. Sounds like it could be as simple as a junction box that accepts VHF and UWC inputs, and a toggle switch to select the appropriate radio. Nyutco modified his headset to use two boom mics, one for VHF the other for UWC. I don't remember how we switched between the two transceivers though. Maybe someone else does.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">The STX-101 will be easy to modify for off-the-shelf headsets. It uses a separate banana-clip jack for headset and microphone so there should be no cutting of wires necessary. The SSB-2010 is going to be more of a hassle because it will require cutting and splicing their stock wire adapter.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Jon</div><div dir="ltr" data-setdir="false"><br></div><div><br></div>

<div>Some great thoughts here. </div><div>Jon, are you going to incorporate topside </div><div>Communication through the headset in your design?
