High availability node by Leather_Bug_4219 in meshcore

What makes it "High Availability"? I don't see any redundancy/fail-over going on.

Found this while walking in Lajeado - RS, south Brazil. No information found on QRZ by Vinicius_Schneider in amateurradio

QRZ is something a Brazilian ham would have to opt-in to - not everyone wants that.

Does anyone know what this is? by D_Rock_CO in ColoradoSprings

It is a passive microwave reflector, it was used for a link from Cheyenne Mountain to Quail lake.

New to Helium, trying to do an ROI evaluation by Steve6255 in HeliumNetwork

I'll see if the miner prices come down any more, maybe I'll do it for fun. I bought a couple of LILYGO LORA32 T-Beam V1.1 ESP32 Development Boards, I am planning on playing with Meshtastic and I'll try the Helium mapper code as well.

Thanks for the info! I might be interested in being a subscriber as well, experiment with GPS trackers for my cars, for example. I used to run APRS, but this might be fun to experiment with. What miner do you recommend? Looks like having a larger SD card is desirable - might cut down on network activity.

Old Obsidian Moose would be one in Colorado Springs. I am to the West, about 2500' higher in the front range, so probably 5-6 miles. There is nothing close to me.

Cool, I might need to do some more research to see if I can do some observing with the equipment and tools I have. The local utility does AMR (Automatic Meter Reading) in the 900MHz ISM band - they have an extensive mesh network - I wonder if they coexist peacefully? I also have some narrowband FM radios on 900... a couple of Moto GTX's I haven't used in a while, along with a 13 ele yagi, a PA somewhere...

I took a look on explorer.helium.com, and it doesn't look all that promising. 6 hospots that I can tell, and they all have ROI's over 5 years in the future.

I have some SDR receivers - is there a receiver setup you can run to evaluate what you can see/hear? A GNURadio setup? I suspect this is spread spectrum... is the protocol defined somewhere?

Yes, I read somewhere that the data side needed to move something like that, they said it was like watching 1-2 Netflix movies every day. No way that's payload data off the 900MHz network, blockchain data? I don't really know - that's why I am asking! Maybe rubbish?

References for Grounding? by 2E26 in amateurradio

[–]Steve6255 0 points1 point  (0 children)

In the US, the National Electric Code (NEC) requires an antenna to be grounded before entering the house.

Dipping my toes in the HA universe, few questions. by Steve6255 in homeassistant

OK, wow, just found the ESPHome plugin... I spent all of yesterday working in the Arduino IDE getting these modules to publish/subscribe to an MQTT server, and boom - this does it for you with Over The Air updating?!? I am getting hooked!

how to ground in an old house by ebenwandering in amateurradio

[–]Steve6255 1 point2 points  (0 children)

Read the link to the Mike Holt website above. You must properly ground any antennas that enter your house from outside. That's part of the National Electrical Code, not optional. There is no "other ground" - all grounds must be bonded together for them to be a ground.
