Good evening LoRanauts! Just a quick video explaining some of the things I considered for my long range broadcast attempt. The link for the antenna I use is below: www.aliexpress.com/item/10050... Have a great week!
Correct me if I'm wrong, but default is 3 hops, max is 7... I mean there's even a feature in code that corrects you if it's more than 7 and it's been a standard since quite a while and I couldn't reproduce that 5 hops thing on any release... Don't want to be rude, but 5 sounds a bit unreasonable to me. But the bedroom lamp analogy is well done :)
You're not wrong. Max is certainly 7. Default is 3. But I can hand on heart say when I went through the defaults after a full chip erase FW upgrade, the hop limit was set to 5 as I mentioned in the clip. I have no explanation for that.
In my experiments on UHF (446) + 70 CMS I've found moving feet sometimes CMS lol can make all the difference..even in the house..topography is king along with height...I can only imagine the 800 megs is strange along with (if)any propagation ...summer should interesting on your band
Well, y'knos what even with the line of sight thing in mind, i cant get a single km between two v3. Will try as soon as i can placing repeaters in peaks, but still, just between two nodes each at the opposite of a street, the max i could do was 250m (woth elevation).
It's possible to transmit over that distance, with high gain antennas, but would be challenging. Using a drone adds another level of complexity, and legislation. A "drone" can only go to 400ft AMSL, a model glider could go to 1000ft AMSL, but even so, that's not high enough for line of sight to another country.
@@JD_fpv At 5:41 in your video, you change the config to 5 and state that it was changed in 2.2.21. It wasn't, it's been 3 for four years according to the firmware code on GitHub.
@@JD_fpv It has been 3 by default since the beginning. It has never been set to 5. From the code: /// We normally just use max 3 hops for sending reliable messages #define HOP_RELIABLE 3 It has always been that. Not a big deal but wanted to mention it in case someone thinks it is 5. I flashed 2.2.21 onto a heltec V3 and it is still 3.
