I took the antenna down and testing it again on the ground, it’s more like 0.8 ohms center to outside. That is a dead short and likely my problems. Thanks!

Some antenna designs can be a dead short at DC and present a correct RF load. But the one you have is very likely a collinear design with “stacked” elements, which should be open circuit.

Everything else you described sounds normal. So hopefully this is it!

A few things to work through:

Try running just off the battery for a little bit with the power supply off and unhooked, to see if it’s supply related.

Check the inside both sides of the N connector, I’ve seen bad punching/forming of the connector body leave a little bit of metal swarf in them which can short them.

Check the continuity of, and for a short circuit between, the inner and screen conductors of that tiny Lora antenna cable. You might need a needle to get the centre pin on the mhf-4 end.

Check for an open circuit between centre pin and outside of your antenna, there should be no continuity with that antenna design.

Take the antenna off and put a 17cm length of bell wire in the N connector centre socket pin and try that, that is pretty close to the length you need for 915MHz. Don’t stretch the pin socket doing that though.

And check for a stretched pin, or a pin that’s been pushed back into the N connector, on both sides of the connector. The centre pin and corresponding socket should be nearly flush with the top of the connector.

Take the antenna from your other device and try it ( u.fl should fit ), just in case you’ve got a mislabeled antenna that’s 868 instead of 915MHz.

That’s a good price for demons, I’d get a few.

Well, antennas are pretty simple physical devices so a close visual inspection is the next step, looking for damage to insulators and spacers, etc

Eggbeater antennas also usually have a bit of phasing coax that by necessity sits out in the weather between the connections to the two elements, probably best to eyeball that too.

Why are ya’ll still attached to that stuff?

It comes with every phone and is the lowest common denominator.

So I can ask a recipient what messaging-app-de-jour they are using, and then install said app , or I have to convince them to use MY messaging-app-de-jour and get them to install it. All this has to happen outside preferred channels of communication, because we haven’t yet figured out what shared methods we can communicate with.

Orrrrr I could just send them a SMS and know that even if they are using the shittiest, most locked down non-free piece of crap phone possible, their phone will go 'bing! ’ and they will receive my message.

Japan could have done this in a weekend. Ok, maybe not the entire CRR project, but definitely the final splicing of it into the rest of the network.

Fantastic. A quality unpopular opinion, well done.

Have my … upvote? Downvote? Which one is it?

Repositioning the taskbar is one of the top asks we’ve heard from you. We are introducing the ability to reposition it to the top or sides of…

Not introducing, RE - introducing, just like how you could before. Alllllll the way back to Windows95, UNTIL YOU MESSED WITH IT.

Basically the whole post is “blah blah blah we screwed around with things so much blah blah blah we messed up file explorer blah blah blah we’re working at putting some minor things back and walking back forced updates a little and cramming AI into everything because that’s what we really want to do.”

Yeah you guys should really sort that out.

If you have a 1500km range then all the people who can’t charge at home only need to charge it somewhere else once a fortnight.

And it’s also a big fuck you to all the people who claim they have a hard requirement to drive across continents every weekend and thus simply cannot drive an EV ever.

Oh, you know, only about 80 billion.

Could have given 10 bucks to everyone on earth, would’ve had more impact.

My department just gives them a PDF explaining with cool graphics how Linux can save more money, how more secure it is, how we can avoid the constant force fed bug filled updates that MSFT pushes, how we can customize it exactly to our and users needs, we can actually own our own keys… The goes on and on.

No, because there is no simple point and click group policy/active directory equivalent in Linux that allows a group of 5 IT techs to manage 2000 desktops. And if you get your shit together and actually use the tools that Microsoft provides, you don’t get surprise updates, you can image PCs via a gui over network booting, you get bitlocker keys backed up in your domain etc etc etc etc etc.

All the things that allow a business to manage hardware and software with the minimum amount of expensive employees, Microsoft provides it, for money of course. That money is offset by the reduction in IT guys needed to look after everything.

It’s that simple. CorporateLand won’t touch Linux on the workstation until that’s possible.

If it’s classed as a “major” fault that essentially renders it unusable, the customer gets to choose the remedy, not the retailer.

This is usually so the customer can get their money back for a shit product, but there’s nothing stopping them from a replacement.

Umart’s claim that it’s “an upgrade” doesn’t hold much weight. If you buy X gigabytes of ram and it fails and you want a replacement with the same X gigabytes of ram, that’s not an upgrade. It’s restoring the status quo of the original purchase where they got a physical quantity of a product.

I’m not sure, but if cake is being served, count me in.

Anyone completely switching off windows needs a bulletproof system

A solid 90 percent of home users just need a browser, email, and access to some kind of app store or repository where they can click on the big colourful icon and get a program they want.

Any modern distro can provide that, it doesn’t have to be the particular one that you’ve got an obsession about.

I take umbrage at item 4, but I don’t have the time for the correct kind of reply.

If you could go to chatgpt and put in this prompt for me and then read the result, that’d be great.

“Please make a long, meandering reply to the assertion that Nic Cage should not be in movies, stating that Nic Cage is perfect for those movies that need that Nic Cage energy.”

Very slow frequency modulation. Slow enough you could hear the tone change slightly as it shifted modulation every few seconds.

Frequency Shift Keying is the more accurate term for this, as it’s not a continuous shift up and down of the frequency like you’d get with FM radio, it’s stepped.

If you imagine a higher tone being decoded a “1” and a lower tone being a “0”, basically it was something like that. Listen long enough and you’d get enough 1s and 0s to build up a message.

That part’s easy, you just mine a tunnel, and then you mine a parallel tunnel 500m away from the first one. Ta-da , 500 metres of solid rock now exists between the two.

Note: mining a tunnel through solid rock can be somewhat difficult if you don’t have the right equipment, YMMV.

But seriously, the amount of dicking around maintaining the loop and the limited abilities of VLF meant that you would quite quickly have to run leaky feeder and bidirectional amps for two way radio, or you’d build a network using fiber and use Wi-Fi. We primarily used the system for remote blasting, and then once technology progressed a bit the initiators were connected via the network instead.
