It is also rated at 5 Watts unless you have one of the 101M or 101SB variants. The surface box just gives you the ability to broadcast audio locally via the speaker, record via the line-level RCA out, allows for external power, and of course provides local control of channel, volume, and squelch without having to navigate voice menus. More convenient than the SSB-2010, but perhaps not an ideal form factor if you are operating it from a very small boat. The diver units with a conversion kit (headset) are much more portable and tolerant of getting wet.<br clear="none"><br clear="none">Interesting that OTS has not updated their surface box to match the 3000D power rating.

<div dir="ltr">I don't, in fact, know that. However, I will likely use headphones in the submarine and I do believe it is the STX-101 weather-proofed speaker that is responsible for the garbled audio. I base that on the fact that topside I had a very difficult time understanding comms with STX-101 and too many times asked someone else "What did he say?" When I dove R-300 and used headphones with the SSB-2010, comms was nearly perfect with easy to comprehend spoken word from topside. That is at least anecdotal evidence that the STX-101 microphone was not the issue, nor the SSB-2010 headphone.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">Assuming the weather-proof speaker in STX-101 is in fact the problem, I can bypass it and use a better external speaker without any permanent modification to the electronics should I choose not to use headphones. But there are other reasons for my choice, including the fact that the 101's have more power and should there be another 101 at the surface I hopefully will experience better comms/range simply based upon power alone.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">My recommendation to others is to use SSB_2010's in both submarine AND at the surface, both with the headphone attachment. I'm was forced into a corner because I had already purchased the STX-101 before ever using it in the field.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">Jon</div><div dir="ltr"><br clear="none"></div><div><br clear="none"></div>

I intend to reverse the roles of the STX-101 and the SSB-2010 having convinced myself that due to my previous experiences with the 101 topside (none of them good) it makes more sense to have the 101 inside the submarine. The OTS STX-101 case, however, is very bulky at 6.5 inches in depth (165 mm ) and simply takes up too much real estate, primarily protruding too far within the cabin of a Kittredge sub when mounted on the ribs. Additionally, the case cover raises only 90 degrees and is essentially non-removable which makes placement within the confines of a K-sub almost impossible.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">The STX-101 case is required to be bulky only because it is designed to carry two 6-vdc lantern batteries as power in the field, underneath the STX-101 panel. These lantern batteries are unnecessary when powered by submarine main batteries and it turns out that the electronics for the STX-101 will fit easily into a box only 1.5 inches deep (39 mm). This substantially reduces the real-estate required by the device and in fact allows it to sit recessed within the ribs of the submarine if installed vertically. Even when mounted horizontally across two ribs the home-built case protrudes 75% less into the cabin than the stock STX-101 case.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">A separate carrying case can be purchased from Harbor Freight or similar outfit to protect the STX-101 in it's new housing. As well, the STX-101 electronics can be reinstalled into the original case at anytime since the "thin-box" requires no modifications to the electronics.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">I built the box out of 3/4 x 1.5 composite trim found at Home Depot. The backing is a 1/4 inch plywood panel. The box will be covered with multiple coats of paint to seal and protect the back panel. Since all connections enter through the STX-101 front panel, there are no holes to drill or modifications to be made for power, mic, speaker, or transducer.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">Jon</div><div dir="ltr"><br clear="none"></div><div dir="ltr"><br clear="none"></div></div></div></div>_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a shape="rect" href="mailto:Personal_Submersibles@psubs.org" rel="nofollow" target="_blank">Personal_Submersibles@psubs.org</a><br clear="none"><a shape="rect" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" rel="nofollow" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div></div>
