I’m still fighting with Amazon to get my first pair of devices delivered, I went with heltec v3s to get started.
But looking at the meshmap.net, it’s very very sparse around me. How likely is it that the are nodes that aren’t on the map?
Hopefully I can check it out myself soon!
Once you find out, please let me know as I only see Like one node in my area and the rest are way far away. Like out of RF range far away, unless you were both on high tower structures.
Seems like most people are saying there’s way more nodes than the map shows. It’s not a guarantee though. I say give it a try!
Sweet. I have been seriously considering getting one of my own to play with. The Lilygo T-Deck Plus is the one I have my eye on.
Looks sweet. I might end with something like that eventually, but honestly I really like the idea of using my phone and just linking the mesh device to it. Reminds me of the old goTenna before they sold out.
Do you have somewhere high you could mount a repeater/router node to? Like the chimney of your house or something? Would make it even easier to connect with people, at least from home.
I’m planning on putting a few up, one at my house and each of my buddies houses.
FWIW only about half the nodes around me have location broadcast enabled. The rest don’t appear on the map but they’ll show up if you receive their nodeinfo packets
My area shows two nodes on meshmap, my heltec v3 sees 100 nodes, of which 50 are on the map in the meshtastic app. Different locations probably have different results, but I’d say that you’ll be pleased when your nodes arrive, I was!
There’s way way more nodes around me IRL and I see new nodes every day. Join us! Make sure you buy a good antenna, the ones that come with heltec v3 are only useful for receiving but are no good for transmitting unless to another device that’s basically touching it.
Thanks! You mean I should get some of those sma adapters and some of those little stick antennas? Or something even bigger? Recommendations?
I’m a ham and I’ve got a nanovna, I could try making a ground plane antenna for 915mhz.
My plan is to put a repeater/router up on my tower 30ft up, as well as on a couple of my friends roofs, hopefully making a stable emergency channel between us. I’m between my buddies, 13 miles between the furthest ends, I’m almost in the middle.
I think you probably have much more radio experience and knowledge than I have, then. I just bought a highly rated 915mhz antenna on amazon with an SMA adapter, it looks like and is the same size as what you’d screw into a wifi router or wifi adapter, with a 90 degree bending joint, but obviously for 915mhz band instead of 2.4ghz/5ghz wifi. I have heard that bending the 90 degree joint on these antennas will reduce performance, so I keep it straight while transmitting and it fits better with the device in my pocket while bent. I have a custom case that fits a heltec v3, a 3000mah battery, and mounts the antenna SMA adapter to the case (case also found on amazon)
Honestly the Amazon antenna will probably do perfectly fine, I might go that way for simplicity sake… maybe I’ll build an antenna too and do some a/b comparisons.
The 90 degree angle doesn’t hurt performance inherently, it only hurts it because it puts the antenna right next to the body of the radio, blocking some of the signal, and detuning the antenna slightly as well. So you’re still better off putting it vertical 👍
Also in case you didn’t know, those antennas are vertically polarized. That means when the tip is pointing up to the sky, the signal is coming out the sides going off towards the horizon. That’s the best way to get a signal out/in. Holding it sideways will create null points from the tip and base of the antenna, and also send half your signal into space and the other half in the ground 😁
Here are my 2 heltec v3s, one stays at home and the other is for on the go.
So far no nodes other than the two I bought. I got the upgraded longer antenna, and went out on my second story balcony in a suburban area, nothing.
Looks like I’ll be the change I want to see in the world haha.
Aw, that’s disappointing. I’m a little surprised, but it still a DIY hobbyist niche and must just highly depend on your area. I’d leave your nodes up and see if anyone joins at some point in the future. Also double check the settings to maks sure you’re on the public LongFast channel?
EDIT: even with all the nodes that I connect to, there is almost no chatter happening on the public LongFast channel. People are quiet 🤷
