Amateur radio operator from Russia | Full-size ham in every sense of the word | Chasing DX from a high-rise rooftop (~60 m AGL) in a small town on the Oka River | HF, antennas, propagation, macOS ham workflows | Radio has no borders — that's the whole point.

Our regional MeshCore network is really taking off 🚀 Over the last 30 days the map shows 559 active links, and the mesh density across the area keeps climbing.
My backbone repeater (node DZ-ZAP-03, the westernmost point near Dzerzhinsk) is holding a long-haul link — 39.2 km out to node NN-PRI-21. For LoRa that's a solid result, and proof the backbone is doing its job.

What goes up tomorrow on the EFHW feedpoint assembly:

— WRLW 1:49 transformer, weatherproof enclosure, silica gel inside
— Diamond CA-35RS lightning arrestor
— CMC choke, 12 turns, 2×FT240-43, RG-8X
— Spring shock absorber
— Dyneema support line

Wind, UV, rain, hail, static — it needs to handle all of it. No maintenance access at 60m AGL.
