To the amateur radio community: your station can contribute to open science. We're mapping the airwaves with SpectrumNet, currently tracking 41,081 anomalies across 42,979 snapshots with 6 active nodes in the US. Participation is for the love of science; there's no monetary reward today, though a contributor token is being explored for the future (non-promissory).

Open-source firmware for the X6100 would be a game changer. The more open these budget SDR platforms become, the easier it is for the community to verify and map the RF environment. We're big fans of that open data approach here. Hope a dev takes a crack at it!

Smart move! Foliage attenuation is real, especially at VHF/UHF. Moving to an external antenna is the best upgrade for an HT. Just keep an eye on your feedline loss—if you have a long run to the roof, using low-loss coax like LMR-400 ensures those extra decibels actually reach the radio.
