Where did you get your SMA pigtail for the antenna? I keep buying the wrong one

@zerofox3d 10 дней назад

Pop me a message bud and I’ll send you a few of my cases, they are widely regarded as the best available and I ship worldwide (I’ve had a very humbling few months since I went a little viral) I wish I was as comfortable as you talking on camera 😆

@N1RIP 21 день назад

For 3D printed fasteners etc, I really recommend getting a Harbor Freight tap and die set.. it will literally last you a lifetime and make those fasteners go in much easier. Go ahead and pick up a combination tap drill set as well. Pop right in your drill and ream'er out. Nice vid Josh

@chrisjohnson8741 21 день назад

A small thing, but it's a good idea to shut down the device before disconnecting the antenna. 95% of the time it's fine, the other 5% it's toast.

@glevideo 21 день назад

Check the resonance of those long antennas with your Nano VNA. Mine were resonant at around 830 and 850 MHz. Nowhere near 906 MHz. They need a little work. If you crack the antenna open to trim it, do your VNA check with the antenna cover slipped back on because the cover does affect the resonant point of the antenna.

@HamRadioCrashCourse 21 день назад

Did you consider that you weren't giving it a good enough ground plane to test it effectively? HT antennas are a nightmare to SWR test since you're generally not creating a good enough ground plane in most cases.

@fax565 17 дней назад

Just got a few of these on order. I wonder if I could put one on my HS720G drone if there is any issues legality wise with this. Might see a few other nodes that way.

@TrevHolland 21 день назад

Tried getting in to this but they are way too hit-or-miss with transmissions. My messages come back as "ERROR" and look like they didn't get received even though they were. The Meshtastic team offers no support. People on the Discord say the same canned response, "get a better antenna" or "get it higher." Meanwhile, I'm at 1000 feet with an upgraded antenna. And 7 max hops means you're only talking to folks within a close area. It's a neat technology but, for off grid comms, it's a novelty. Better off getting a HAM license if you want to communicate off grid.

@DawnPatrol-ce5rk 21 день назад

Sounds like u, much like many many others found out way too late in the game had a burnt device. Usually occurring when antenna not plugged in and pwr on, the rub of it is- it still works just at very marginal minimal distances, so it appears to be in fine order though it may not be. This is popping up all over the place. That said it’s sure far from perfect, but that’s the hobby of it, if it weren’t that way, there would be 7B of them out there in everyone’s back pocket. But it improves everyday and is a lot of fun and 1 of very few options in the sector for the non licensed

@TrevHolland 21 день назад

@@DawnPatrol-ce5rk I certainly hope I'm wrong on this, because a burned radio would make me at least feel better about this whole thing, but I don't think mine is. I have nodes pretty far away in my nodes list, with an SWR of +/- 5. I know an SWR of 5 is generally trash, but I was told that's a common SWR for these little whip antennas. I'm not sure how to check which nodes were my first hop, though. I'll contact the seller (this was a prebuilt unit from Etsy) and see if a burnt radio is a possibility, though.

@TrevHolland 21 день назад

@@DawnPatrol-ce5rk Well, after some testing and doing traceroutes, I am hitting nodes around 5 miles away (on a hill that I can see from my house). They're using GPS so I'm fairly confident in the distance accuracy. It doesn't appear to be a burnt radio. That said, nearly every message I send still results in a cloud with a line through it and the status "ERROR". Oh well.

@ChristopherJohnston-ml6pc 21 день назад

@TrevHolland I have verified 5 miles on my RAK Wisblock devices using Google maps after sending messages. Both were my own nodes so I was able to verify the message after I got home from the test. I have 4 RAK nodes.

@rainmannoodles 19 дней назад

I got a pair of these to experiment with. I knew about the potential issues with the antennas not being plugged in (honestly, something the hardware should be able to deal with, but these are cheap Chinese trash radios so whatever) and I had no problem connecting the two nodes together. Getting more than about 1-2 blocks of range between them (line of sight) is basically impossible. And I've seen exactly 0 nodes anywhere - I've driven around with one, taken it multiple places... nothing. I suppose there are some very specific pockets where people are running dedicated high-gain repeaters, but otherwise Meshtastic is basically a novelty.

@patrick70335 21 день назад

Hey, does anyone know if I can hook up the meshtastic to a ring solar panel and charge off that? asking for a friend : )

@huseinabdul1 21 день назад

What is the plug type for that? I just looked it up it looks like it’s putting out 5.5 V which I think might be good, but don’t quote me on that.

@huseinabdul1 21 день назад

Sorry I meant is it a USB plug? I’m not familiar with ring stuff. I bought a few solar panels from Amazon that worked plus bought a few more from AliExpress that also worked as long as they’re around 5 V.

@patrick70335 21 день назад

@huseinabdul1 it's a USB C. Ideally I would hope this is running Ning off the battery and there is a charge controller built into the meshtastic. So it shouldn't pull in all 5 volts.

@huseinabdul1 21 день назад

@@patrick70335 i’m pretty sure it actually does charge, but I’d be careful to push it. I used a different model where it actually had a spot to plug a solar panel into it to me was a little safer. I’m pretty sure this one should be fine.

868 is the EU frequency. You probably just bought the wrong thing or bought it from an idiot seller.

@joestubblefield1948 21 день назад

can I talk/test with a mesh say 150 miles in a rule area?

@LeeMcc_KI5YPR 21 день назад

Not without substantial antennas on both end.

@TrevHolland 21 день назад

Even with substantial antennas, the answer is very likely "no". Unless you have zero obstructions, most tests are showing about a 3 mile range between nodes in typical environments. 7 hops, maximum, means you'll get about 21 miles, and that's IF you have enough nodes to propagate the message. Even if we give it the benefit of doubt, call it 25 miles, and double that distance, you're still only at 50 miles. Triple it? 75 miles. Still no where near the 150 you're after.

@LeeMcc_KI5YPR 21 день назад

Sorry...I understated when I said "substantial". I was thinking highly directional (big dish), and cell-tower tall. Substantial. With rare exceptions during very rare atmospheric phenomena, the frequencies are line of sight, which means you pretty much have to see the other antenna.

@BoboAthanassion 21 день назад

I'm a stupid HAM, but can you tell me why one would build these devices and for what purpose. However; it does look like a fun and educational build.

@scotterdog1036 21 день назад

It's a gateway drug to ham radio. 😊

@scotterdog1036 21 день назад

@LeeMcc_KI5YPR 21 день назад

If the internet and phone networks are down, it is a way to have comms in a community. Maybe a hunting camp, as @Ham Radio 2.0 suggested.

@HamRadioCrashCourse 21 день назад

The reason to build these is to communicate off grid with other people or share local sensor data.

@major__kong 21 день назад

These kinds of devices trace back to things like goTenna, which isn't making consumer devices anymore. Their use case was allowing a group to stay in contact without cell towers and not need a ham license. So things like camping and hiking. However, I suspect goTenna got out of the business because that use case for the average person just isn't important, and they probably didn't have great sales. If you do emcomm or support something like CERT, you could imagine these being used at the tactical edge and gatewayed to ham radio or part 90/95 radios for back haul. You could probably do ICS form data with these things.
