Hey Tony, I've (unfortunately!) not had a chance to visit the hackspace in a while, but caught this email in an unrelated search and figured I'd offer some advice on antenna experimentation. There's a thriving mesh in Glasgow and I've been fortunate to pick up a few nodes over RF (plus loads more on the `msh/Scot` MQTT topic). The stock antennas are often poorly bandmatched, so I'd really suggest picking up something like https://www.aliexpress.com/item/1005004607615001.html Watch out for the connector types, but you can directly attach one to a T-Echo with the "868Mhz SMA M" variant. You could also use a https://www.aliexpress.com/item/1005003823116481.html to attach the same type of antenna to a Heltec V3 node. I've had *excellent* results running a 'base station' node at home with the aforementioned combination, extending my range to ~7km. (https://www.thingiverse.com/thing:6540986 also works as a cute case for the Heltec V3 with an external antenna) I received a LILYGO T-Deck Plus earlier today, so have been excited to continue experimenting with this- hopefully won't be too long before I'm able to visit youse in Aberdeen :) Best, Harley Watson (it/she) El Mar, 10 Sep, 2024, a las 16:32, Tony Travis escribió:
