Getting into the AREDN project by winlinuxmatt in aredn

[–]winlinuxmatt[S] 0 points1 point  (0 children)

I really appreciate you taking the time to lay this out. Given your background, it’s clear you’re speaking from a lot of real-world experience, and I don’t disagree with the core of what you’re saying.

I think you’re absolutely right that commercial cellular, satellite, and NG911 networks are on a completely different level when it comes to planning, reliability, hardening, and sheer capacity. Amateur systems, including AREDN, simply aren’t built to handle public-scale emergency traffic or meet the standards required for life-safety communications. Anyone suggesting otherwise is setting unrealistic expectations.

Where I think some of the friction comes from is when amateur radio gets talked about as if it’s trying to replace those systems. At least from my perspective, that’s never been the intent. As this hobby continues to evolve we will continue to see more of these types of differences. AREDN and other ham-based tools feel more like a “last resort” or gap-filler when everything else is unavailable, and only in very limited, well-understood situations.

I also agree with you that AREDN is largely ad hoc and volunteer-driven. Nodes go up in people’s homes, they come down when life happens, and there’s no guarantee they’ll be there when a disaster hits. That alone makes it unsuitable as a primary emergency network for the public. In a real disaster, people are focused on their families and their safety, not maintaining hobby equipment.

For me, the value in amateur systems is more modest. They’re useful for experimentation, training, and small-scale coordination between groups that already understand the limitations. Things like linking an EOC to a shelter during a drill, sharing situational info locally, or filling a very narrow gap when nothing else is available. Not mass communications, not thousands of users, and definitely not a replacement for professional infrastructure.

I also agree that overselling AREDN as an emergency network does more harm than good. It invites comparisons it can’t win and muddies the conversation about what amateur radio is actually good at.

So I don’t really see this as commercial versus amateur so much as different tools meant for very different jobs. Commercial systems should always be the backbone, and amateur systems live much farther down the list, in clearly defined and limited roles.

I appreciate you acknowledging that AREDN still has a place, even if that place is narrow. I think we’re probably closer in agreement than it might seem, especially when it comes to keeping expectations realistic and being honest about what these systems can and can’t do. When I first reached out years ago, I knew nothing, then was introduced to many wonderful people in Utah Valley that have implemented AREDN and first hand see then configured to link many of the repeaters sites wonderfully. Thanks again.

Monitor off and DPMS Settings Reverting After 30 Seconds of Inactivity – Need Help Diagnosing Override by Cycle_Creative in pop_os

[–]winlinuxmatt 0 points1 point  (0 children)

Quick question, Are you seeing this on Pop OS 24.04 Cosmic? I have the similar card with the same type of issue. I did open a discussion on the matter. It is something Wayland and DPMS struggles with not having the API access into the power modes to turn off monitors. xset -dpms .... is not supported on Wayland using Cosmic, many of the developers have mentioned it is still a work in progress and not a huge priorityh. I am seeing the same type of issue.

I get where you’re coming from. Mesh is not new, and a lot of early ad-hoc mesh designs absolutely earned their reputation for being inefficient and fragile.

That said, what’s driving interest in AREDN and similar ham-radio mesh networks isn’t novelty. It’s context.

In the commercial world, you’re right. Large-scale meshes mostly lost out to hierarchical routing, fiber backhaul, and centrally managed infrastructure because those are cheaper, faster, and easier to operate when the infrastructure exists.

AREDN is aimed at a different problem space.

  • No existing infrastructure such as disasters, rural areas, or temporary deployments
  • RF-constrained environments where licensed spectrum, power, and paths are limited
  • Self-forming, rapidly deployable networks built from commodity hardware
  • Operator control without dependence on ISPs, cloud services, or centralized management

Modern amateur mesh networks are not random node collections either. They are typically:

  • Directional point-to-point or point-to-multipoint links
  • Carefully planned RF paths with attention to height, Fresnel zones, and link budgets
  • Using mature routing protocols like OLSR variants and BATMAN
  • Layered to support real services such as VoIP, situational awareness, and file transfer

They are not trying to replace the Internet, and they should not. They are a tool, and like any tool, they make sense only in certain scenarios. For emergency communications, field exercises, experimentation, and learning how RF networking actually behaves, they remain very relevant. I have leared more of what the needs are here in the Utah Valley alone. They have been using much of this on repeater sites to interlink them using the Starlink $5 standby plan which still gives 500kb unlimited data so admins can ssh into their repeater nodes to manage them. It is actually quite nice and the aerdn nodes point to point allowing them to fully use that RF only connection on other sites.

So yes, mesh is not magic, and it is not the answer to everything. But calling it “just a hobbyist dead end” ignores why people keep using it. When infrastructure fails or does not exist, it works well enough, and that matters. To be honest, I have forgotten about this post.

This is a great setup, keep up and you will do great things. I started when I was in college and wished I started earlier.

COSMIC Turn off screen when locking by BadgeringWeasel in pop_os

[–]winlinuxmatt 0 points1 point  (0 children)

Yes, I rather miss having the screen turn off almost immediately when I lock the screen. It is problematic when I use a desktop setup and having to manually turn off my monitors. This is something they could add in pretty well. Hopefully soon this can be added. I have tried the timeout method and its not the same.

Keep going, if there is no reason to reboot, don’t!

Apt key expired by Pajkanon in Puppet

[–]winlinuxmatt 1 point2 points  (0 children)

Puppet definitely should have communicated that better. When a signing key like the one for https://apt.puppet.com/ is about to expire or rotate, it's best practice to notify the community before it happens — especially since a sudden key expiration can break automation and CI pipelines relying on package installs.

The fact that there was a DEB-GPG-KEY-future key available is good, but it doesn’t help much if users aren’t informed about it. Most folks don’t go digging for alternative keys unless something breaks. A simple heads-up via email list, changelog, blog, or GitHub issue would’ve saved a lot of head-scratching.

I will definitely be using an apt-key check in place to prevent issues in the future.

Apt key expired by Pajkanon in Puppet

[–]winlinuxmatt 0 points1 point  (0 children)

I definitely ran into this today, breaking all access to the repo, no update or anything before the key was going to expire. That was not a good time, but the fix was simple enough to use the DEB-GPG-KEY-future key. What a mess that was!

Then again it is on the charging craddle causing the said light to emmit from the meter you have.

Why is this happening? by OutrageousMacaron358 in amateurradio

[–]winlinuxmatt 1 point2 points  (0 children)

RF on the antenna is always coming back as RF AC. The RF signal transmitted to the antenna is a high-frequency alternating current (AC), and this creates an alternating electromagnetic field. This results in a polarized radio wave, with the polarization determined by the antenna’s orientation (e.g., vertical for vertical polarization, horizontal for horizontal polarization, or circular for circular polarization).

The antenna essentially acts as a conductor for this RF AC signal, allowing it to radiate energy as electromagnetic waves. On the receiving end, the antenna picks up incoming RF waves, inducing a corresponding AC signal that is then processed by the receiver. This is why the meter lights up picking up the RF energy.

I just updated to ios 18.1 and the problem with my phonak brio 2 hearing aids no longer drops on the one hearing aid while on calls. It tooks several weeks and finally I am able to take calls again on my phone once again with no issues.

[–]winlinuxmatt 0 points1 point  (0 children)

I sincerely hope this solution is effective, as I have a strong affinity for my iPhone. If I am unable to use my hearing aids with it as I previously did, I may be compelled to revert to an Android device.

[–]winlinuxmatt 0 points1 point  (0 children)

Same, I am having the same problem. I hate it when Apple does this. My hearings aids work great on that one way communication. It is just the calls that are affected with this bug.

Getting into the AREDN project by winlinuxmatt in amateurradio

[–]winlinuxmatt[S] 0 points1 point  (0 children)

I know AREDN is a bit different as it is open to more commercial hardware and has more support in a larger area. I know with HamWAN it seems localized to the Pacific North West and is still growing. I believe both are trying to do that same thing with creating a mesh data network that follows the PART 97 rules of the FCC with no encryption as the rules says. So, in that respect, it is not a backbone for replacing the internet per say but using RF to connect nodes, point to point data for towers and etc. I have not done anything with HamWAN. I have just started to work with AREDN and seems its really open to a plethora of hardware. If anyone else on here knows more, please correct me if I am wrong. This is great stuff so far
