    Garmin inReach SOS Outage on 25OCT2021

    That's the ultimate question. From the perspective of the device -> constellation there's no difference in messages, one short burst data packet is like the other to Iridium or Globalstar. With InReach there's another level going from Iridium to Garmin so exactly where the hiccup occurs could...

    Garmin inReach SOS Outage on 25OCT2021

    It happens with Iridium but also could happen with Globalstar or any network really. In this case a 406MHz COSPAS-SARSAT PLB is probably a safer bet for SOS reliability than a RTCM 12800.0 device (who's to say SMS or Internet connectivity isn't a function of backend SEND issues?) but OTOH the...

    (partially) new Tundra coming?

    The typo only exists in the one place that I could find, under the HP peak for the SR trim engine. It looks plausible otherwise, torque peak could be correct at 2,400/2,000 RPM. It's a pre-production document probably done by a graphics designer and not an engineer so who knows, it might not...

    Short(er) Recovery Rope

    Not that I've been above folding a rope or strap in half in a pinch but expecting to do this regularly isn't an ideal solution. This is doubling the effective diameter so the amount of stretch you get is reduced and with such a short length it makes for a more abrupt yank. So it's either...

    Solid state PDM or power distribution module.

    Yeah indeed, I think those 4mm banana plugs usually top out at about 15 amps so obviously the real limitation would be the common power one. But for the purposes of proof of concept in a lab that's a pretty handy little board I bet. And the price isn't all that unreasonable since a single...

    GMRS antenna on smaller vehicles

    Says: - Frequency Range: COVER - 125MHz~525MHz So that means it'll cover amateur radio 2m, 1.25m and 70cm bands as well as GMRS.

    Emergency Use of FRS/GMRS “Channel 307” in Wyoming

    One presumes activation of a PLB prompted the SAR call out in the first place. Doesn't sound like this is intended to be an actively monitored frequency. Someone had to have called 9-1-1 or punched the SOS already. After that having two-way real time between involved parties seems...

    HF Antennas

    There's never a single perfect solution to all the things you want to tinker with in ham, is there? FWIW, though, I tried mobile HF and it's not something I really found compelling. But I drive a stick shift truck in the mountains so it's more a question of attention focus and simply having...

    HF Antennas

    You don't mention what bands you're most interested in using. It does make a difference. You mention Winlink but you might focus only on a couple of bands to improve your chances over nimbleness with an antenna that doesn't perform particularly well on any one band. Winlink is handy because...

    What are the best sources of air lines, manifolds and fitting for on-board air?

    Total agree with @Verkstad. Just use quality Festo, Parker, etc parts. Whatever you can get at typical industrial suppliers or McMaster, MSC, Grainger. They make stainless push fit connectors for food processing intended to be washed down with sanitizing chemicals that might be better for...

    Decision time. Trail Comm with CB required per 4x4 club. Upcoming changes, need WX.

    CB, ham, FRS/GMRS - just use whatever you gotta to communicate with the people you need to. There's pros and cons but that's all it comes down to in the end. Personally I've found the argument about OTR trucks and CBs to be losing steam. They seem to rely more on cell phones and satellite...

    GMRS antenna on smaller vehicles

    LOL, the sheet metal on modern vehicles is so thin that regular NMO mounts barely can clamp without dimpling, not to mention seem like they'd bend up in a stiff breeze. So I reinforced the underside of my roof with something similar. I ended up using a little bit of conductive epoxy rather...

    GMRS antenna on smaller vehicles

    If you can keep separation do that, of course. But understand @drrobinson that there's ideal and there's realistic. So you may have to prioritize what you do to compromise when running multiple radios and antennas. It's not a definite "this is enough" situation where you can say you are safe...

    GMRS antenna on smaller vehicles

    Locating two VHF and/or UHF antennas on the roof is tricky. It's been discussed, in fact. https://expeditionportal.com/forum/threads/gmrs-cb-and-am-fm-antennas-in-close-proximity.217489/#post-2903316 I put two antennas centered left-right on my roof using your option 2 if I understand what...

    Super special custom! I just cut my stock rigid plastic flaps and connected rubber sheet extensions. I'll have to snap a photo.

    GMRS antenna on smaller vehicles

    No ground plane is a misleading concept. What it means is the antenna does not need the ground plane (e.g. the metal of your truck under and around the mount) to achieve a suitable match to your coax feedline. NGP does not give you the ability to just put the antenna anywhere and automatically...

    GMRS antenna on smaller vehicles

    Where @Superpanga has his antenna should work alright but will have a distinctly distorted pattern favoring the hood side. Given the limitations of a soft top and such it's about the best you can do, although mounting it on the roof rack bars might be an option on his truck. The important...
