021 New and Cheap APRS using LoRa Technology
Переглядів 51,288
День томуYou might know APRS location trackers on 144MHz. And you might have heard of LoRa, a relatively new modulation standard capable of bridging unexpected long distances at low power. Combined with cheap hardware and an innovative Austrian project gets us an exciting mix: LoRa APRS trackers.

Hi Andreas, you videos have completely changed my life. I started watching your original channel over 3 years ago when i was still a wildlife photographer with an interest in electronics. Today, i run a small start up that makes wildlife tracking devices using Lora for wildlife in Peru, and the foundation for all of devices was built using your tutorials. I honestly wouldn't be where i am today if it wasn't for your videos. I just wanted to say thank you. As you can imagine, with collars, device size and battery life is our primary concern. I cant wait to get a chance to try this APRS tutorial to see if it is a better system over sticking to Lora. Cheers.

Glad to read that you found a new "profession"! I do not think that APRS is different to other LoRa networks because it uses the same methods. Plus: You have to have a callsign to use it.

Hi Andreas, and thank you for your work and dedication! I have been following you for a few years now and I think that I saw every single episode from your main channel. As fascinating as I find this technology, and even impressive (i.e. reaching a satellite so far away), I am not sure that I understand when/how/why this technology would be used, other than just "for fun" or "because we can". It might be my memory, but I do not remember if you have made any videos about "What is this used for in real life". Could you maybe make, even if a shorter, video, that explains this in more detail? Thank you, keep up the great work!
@HB9BLA 2 роки тому
This is a hobby project and has not a lot of use other than knowing where your colleagues are. Which also could be done using a smartphone. The main purpose is to learn about how to use this technology and to see where it works and where not. Remember: This is the "nerds channel" ;-)
@pete3897 2 роки тому
Amateur radio is about the journey, not the destination. You learn electronics skills and tools and you get inspired and then one day you go "hey, why hasn't anyone built X" and you go and build it. That's the dream :)
@MI7DJT 2 роки тому
If everyone in your family had a LoRa device and you lived within range of each other, you would have your own comms system for simple messaging.. that's one example of a real-life use. Great for emergency comms. I can imagine many uses in outdoor activities where people are not within talking range of each other.
@JoJa015 Рік тому
Lots of great replies to your question. One other thing to consider is that by someone doing this just "for fun" they may come up with a creative end use for it. If you never knew about this technology and did not try it you may not be able to come up with those creative solutions. As one poster mentioned above they use it for wildlife tracking.

@@HB9BLA To be fair though, the LoS requirement is more of an operating frequency attribute then a modulation one. You could use LoRA techniques down on HF and not have LoS issues.

Why hasn't anyone made a dual mode APRS (AX25 and LoRA) digipeater on 2 metres? In the UK the 70cm frequency is right in the middle of the licence-free ISM band, and most people who are raving about LoRA/Meshtastic are using the non Amateur allocation around 800 MHz, to be honest, Meshtastic is just a craze, as soon as people realise that it is only SMS they will rapidly get bored with it, it is reinventing the wheel a bit because you can doing everything already using standard APRS. So why not a dual-band AX25 and LoRA digipeater iGate on 144MHz?
