WRFP399 Posted November 13, 2022 Report Posted November 13, 2022 Anyone here using this system? We just started to dive into it. Quote
SteveShannon Posted November 13, 2022 Report Posted November 13, 2022 Ham Radio Crash Course has a couple videos about it. I haven’t gotten my hands on it yet. Quote
WRFP399 Posted November 15, 2022 Author Report Posted November 15, 2022 So I have a few devices, Lilygo T-Beam V1.1. I placed one up high and placed another one at home and drove around with another. The best I could do so far was about 3.7 miles from the car (device placed on roof) to the node up high. This is with the "Long_Fast" preset. They are also very glitchy and often require a reboot. So far they are fun to experiment with and maybe as use in a PACE communication plan but reliability is an issue so far. Quote
WRFP399 Posted November 18, 2022 Author Report Posted November 18, 2022 Just messing around with it I was getting 10 miles of communication. The RT1 was just dropped next to a road on a hill while I walked around some trails. WRUU653, WRUS537 and SteveShannon 3 Quote
WRUU653 Posted November 19, 2022 Report Posted November 19, 2022 I know nothing of this other than the little bit I read but that seems impressive to me. Thanks for sharing real world testing. Quote
WRFP399 Posted November 28, 2022 Author Report Posted November 28, 2022 Rigged up my first outdoor solar "repeater". Inside this ABS box is a SLA batter (lithium can't do cold weather charge), a small solar controller, a step down converter to get from 12 volts to 4, and a Lilygo T-Beam 1.1 without a screen. It uses 90mA at 12 volts when transmitting and 30mA at 12 volts when sitting. WRUU653, SteveShannon and WRUS537 3 Quote

WRWH978 Posted February 13 Report Posted February 13 I bought two of these to play around with, got about a mile with the stock antenna in my neighborhood. I had a few text messages go through even though the app indicated they did not when it was out of the mile radius. Anyone have a recommendation for a better antenna? Thinking outdoor pole mount. Thx Quote
rdunajewski Posted February 23 Report Posted February 23 I've been tinkering with these as well over the last month. Just driving around with the antenna inside the car I got 1.9 miles through dense suburban terrain. I've had a full conversation with someone about 1.5 miles away with the antenna inside the house near a window. It doesn't appear to be busy here in NJ, but I do see a couple nodes pop up here and there. Thinking about attaching a node to a drone and getting it 400 ft up for about half an hour and see what I get. I also set up an MQTT server for linking my mesh with my father who is about 25 miles north of me, and that works well also. You can't really use the public MQTT server because it will completely flood your mesh and probably lock up your devices from all the traffic, so be careful with that. If anyone is interested I can create a channel on the server to tinker around with. SteveShannon 1 Quote
ShaneJ Posted March 18 Report Posted March 18 @rdunajewski Rich, I am really interested in the procedure you followed to set up your private MQTT server. I have a group of friends in the Tucson area where we are thinking of starting a mesh system to coordinate various search and rescue related activities. Best Regards, Shane Quote
nokones Posted March 18 Report Posted March 18 I got about a mile and a half with my DTR700 in a holster on my belt sitting in a car and was able to monitor other DLR1060s that were out in the open. Quote

DominoDog Posted August 12 Report Posted August 12 Now is the time to be concerned about meshtastic. Apparently some jerk company named nexnav wants 900mhz spectrum for its own nefarious uses. FCC is taking comments on the thing. Not my video but has fcc link in description https://youtu.be/cTkWu7GgTQs?si=_dDi9xdPQxOHkgbS Quote
WRXB215 Posted August 12 Report Posted August 12 @DominoDog Thanks for point this out. People should sound off. Even if you don't care about mesh and don't fear this being used for nefarious purposes, we still need to push back. If you give an inch, they take a foot. And sooner or later there won't be much spectrum left for us. Quote
tweiss3 Posted August 12 Report Posted August 12 I submitted comments because I don't want to loose 902 for amateur radio. edisondotme, SteveShannon and Lscott 1 2 Quote
WRYZ926 Posted August 12 Report Posted August 12 Definitely comment against this change. We don't need to lose any more frequencies. We lost part of the 1.25M/220 Mhz band a few years ago when UPS petitioned the FCC for a portion of that band. And to make things worse, UPS never uses it. Quote

WRFP399 Posted September 6 Author Report Posted September 6 Eh. I ain't worried. The ISM band is filled up with so many LoRa devices they aren't just going to suddenly stop it. Meshtastic has continued to grow and be developed. The Apps continue to be refined and the firmware for the devices has ever improving functionality. There are a ton more devices on the market and we are now seeing MeshTastic devices ready to go without assembly. https://store.rokland.com/products/wismesh-pocket?srsltid=AfmBOopDuYyc38PNZ6uV2JIoHmiSzKw7670XSZsNnOQ2waQAdeyZL-00 radiozip 1 Quote
