This looks like good news indeed (and thanks to Mike Doyle for the head’s up). That little 1.25” diameter Callpod Dragon V2 Bluetooth headset can not only do the expected with your cell phone but also communicate directly with another Dragon V2 headset up to 100 meters away. So, at least theoretically, you and your mate could be working or playing most anywhere around your boat with full duplex hands-free communication as needed, interrupted only if either of you wants to take a call from the individual cell phones in your pockets. Actually, the phone might be stowed in a safer place, perhaps even hooked to an amplifier, as Callpod claims the Dragon “typically enhances the {9 meter} performance of standard Class-2 devices by a factor of 2 to 3 times.”
On Saturday the Apple iPhone app store started offering iNavX Marine Navigation and it’s already generated eight mostly positive reviews there. The $50 program is the work of Rich Ray, who also developed GPSNavX and MacENC, and it looks similarly well done. It works with the built-in GPS of the new 3G iPhone of course, but can also be used on older iPhones using cell tower location services. Alternately you can set it up on an iPhone, or iPod Touch, to get GPS, wind info, and other data via a boat’s WiFi router and a program like MacENC (or Coastal Explorer) that can output NMEA 0183 messages to TCP/IP (Franson GPSGate should also work).
That’s a Blackberry getting dunked in pan of water, which it apparently survives just fine, thanks to a new “vacuum deposited” polymer coating process called Golden Shellback. You can see the CNET video “Waterproof your gadgets” below, Gizmodo filmed a cell taking a call while in a glass of ice water, and Tekzilla had some fun with an iPhone. But I’m a little confused; all these tech sites talk about “waterproof” but Golden Shellback itself clearly calls its technology “splash proof.” Many of us know from handheld VHF history that there can be a big difference.
Let me say right off that the delightful title above—antenna cables and connectors really are important to performance—is stolen whole from a first class essay on antenna cabling written by Jason Reilly. And the illustration is cut from another useful coax connector page by Edward Kuester. I don't want to be an expert on such matters, but anyone who fools much with VHF, GPS, AIS, TV/FM, WiFi, and cellular antennas runs into all sorts of semi-standard connectors, and often the need to transition from one to another. The links above are great for the nomenclature, intent, and limitations of the various types, but I don’t think I’ve yet found the best sources for all the bits and pieces I could use in the lab, and you might need on your boat.
There were 15 entries in the “Aftermarket Electronics, Electrical Equipment, Instrumentation, Navigation Equipment including Software” category of this year’s MAATS Innovation Awards, and not a dud in the bunch! Which is why it’s particularly noteworthy that we seven judges gave the award to Lowrance’s Broadband Sounder and an Honorable Mention to Lowrance’s LVR-880 VHF/FM radio. I’ll be writing more about both these products as I should have samples installed on Gizmo in a week or so. The photo above is from a pre-production 880 that I tried in the lab for a month or so; the NMEA 2000 DSC features weren’t yet ready for prime time, but I was quite impressed with how well it could bring in FM radio while also scanning one, two, or all VHF frequencies, muting the FM whenever squelch was broken. Congratulations, Lowrance!
I’ve long thought that handheld VHF DSC can have real value in a MOB situation, which is one reason I’m delighted that the HX850S is shipping and a similar Lowrance model should soon follow. I also figure that we’ll soon see more Spot-like satellite messenger/GPS/-safety products, and there will be even more confusion about how they work relative to official SARSAT system with it PLBs and EPIRBs (as referenced at the end of the recent FOB entry). But I had no idea until today that Mobilarm was developing a dedicated VHF/DSC/GPS man overboard device, and apparently marketing it as an alternative to a personal EPIRB.
I’ve never met Rob Emmet, founder of Pyacht.com, but have come to think of him as quite the can-do gear guy. Apparently the ISAF (International Sailing Federation) Race Management Team thinks so too. Above, and bigger here
, is the innovative mark management system that Pyacht developed for a certain major sail racing event—with five tight courses sometimes in use simultaneously—that will take place this August in Qingdao, China (Pyacht is not supposed to use the O name promotionally, so I won’t use it either). Whereas Emmet “couldn't see the Chinese allowing us to use the 900 MHz band to stream NMEA data from the marks,” he settled on VHF DSC. Thus all those Standard Horizon HX-850S handhelds will live in special pouches on the marks, where their GPS position can be polled by those Icom IC-M604 fixed VHFs that will be installed on the committee/signal boats. Then each committee boat, plus the Principal Race Officer and the Media Center (and “Chinese Officials”) all get copies of Nobeltec VNS Max Pro so they can monitor the course layouts. Of course putting all that gear together with proper cabling, battery charging systems, etc. and getting it all approved by the ISAF and Chinese government was pretty complicated. Emmet lays out the whole story well at the Pyacht blog. Even if you don’t give a fig about racing sailboats this is an interesting example of how the new GPS/DSC handheld VHFs can be used to track tenders or whatever. Tip of the propeller beanie to Pyacht! (Which, by the way, sends out an occasional newsletter, where I learned about this project.)
What a good idea! Today Cobra is introducing its MR F300 BT Bluetooth handset, which seems carefully designed to make a cell phone work better, and live longer, on a boat. It’s a waterproof marine-style mic with noise-canceling technology on both the receive and transmit sides. It even has a Push-To-Talk (PTT) button like a VHF mic, but in this case it’s really a reverse mute button. In other words, you and your caller will hear no amplified boat noise unless you push the button (and you’ll still hear your caller even when the button is pushed). But if it’s quiet on the boat, there’s a dedicated button for hands-free speaker phone mode. In fact, the 4.5” tall mic even has soft keys able to call up a 50 number received call log and equal size phone book, and other features like 10 ring tones that can be individually assigned to regular callers {correction due to Cobra Web error, now also corrected: there’s just a choice of 10 tones, not selectable by caller}.
When Standard Horizon showed a prototype Bluetooth VHF headset last Fall, they didn’t say which radios it would work with. Now the product scheme has become clear: a new HX760S handheld that comes bundled with the wireless headset, and a BTK-2 kit that can add Bluetoth and the headset to either of its two high-end GX series fixed VHFs. And, by gosh, if you do the Google you’ll find the both the 760 and BTK-2 are actually for sale out there.
The electronics road trip was a blast, and it seemed appropriate that I drove it with three (3!) modes of satellite communications on my dash board, bigger image here.
