Weekly neighbor-link report for the EVV mesh, run October 19, 2026.
7 days of data · 17 repeaters seen · 7,325 relayed packets
What needs attention
- 🔴 KC9EP QTH RPI Repeater: Stopped relaying other repeaters' packets after Sat Oct 17, 12:16 AM. Earlier in the week it relayed 2,313 packets from other repeaters (SIM5 McCuchanville FD, KC9EP Solar, KC9EP-Observer1, SIM1 Deaconess Midtown and Opie's Truck), and none in the 50 hours since. Its noise floor has read exactly -127.5 dBm since Sat Oct 17, 1:00 AM, which usually means the receiver stopped working even if the node still shows online. Ask the owner to check the radio, antenna and power, and restart it.
- ⚠️ Repeater neighbor lists: We can read only 1 of 17 repeaters' own neighbor lists. Each repeater records which repeaters it hears every hour, with SNR. MeshMonitor can read that list over the mesh, but only with a saved guest or admin password, and so far it has one for SIR1 KD4SIR. Until more lists are readable, the grid above has to infer hearing from relayed traffic.
- ⚠️ One-way links: 13 repeater pairs are heard much better one way than the other. SIR3 Germantownship FD hears SIM3 St. Wendel in 94% of shared hours, but SIM3 St. Wendel hears SIR3 Germantownship FD in 6%; SIM5 McCuchanville FD hears SIR3 Germantownship FD in 74% of shared hours, but SIR3 Germantownship FD hears SIM5 McCuchanville FD in 3%; SIM1 Deaconess Midtown hears OAK1 in 66% of shared hours, but OAK1 hears SIM1 Deaconess Midtown in 0%. Some of this is just traffic no observer sees. Unequal antenna height or gain, or noise at one end, is the usual real cause.
- ✅ Strong repeater pairs: The backbone links that hold up most hours. SIR3 Germantownship FD hears SIM3 St. Wendel 94%; SIR1 KD4SIR hears Harmony Way 1W 86%; SIM5 McCuchanville FD hears SIR3 Germantownship FD 74%; Harmony Way 1W hears SIM5 McCuchanville FD 73%; KC9EP-Observer1 hears KC9EP RPI 69%; OAK1 hears EVV-Airport 68%.
- ℹ️ Mobile nodes: Mobile nodes stopped relaying, probably because they moved. Opie's Truck (last relay Fri Oct 16, 11:00 PM).
- ℹ️ Time of day: Marginal links are weakest 12 PM to 3 PM and best 9 PM to 12 AM. Links whose median SNR is below 0 dB heard 35% of adverts in the worst 3-hour block and 70% in the best. Only links already near the edge show this; strong links don't.
