Subscribes to mqtt.pskreporter.info:1883 over plain TCP and folds every reception report into hourly aggregates per (band, sender_grid_4, receiver_grid_4). Each spot is the empirical "propagation actually occurred on this path right now" signal we'll correlate against HRRR atmospheric state to recalibrate the scoring weights. Aggregating at the path-hour bucket collapses 50-reporter QSOs to one row instead of 50. Topic filter anchors on USA (DXCC 291) on either sender or receiver side so the broker pre-filters out everything outside our HRRR domain. Bands subscribed: VHF and up (6m, 2m, 70cm, 23cm, + microwave) — HF is dominated by ionospheric propagation, which this project doesn't model. Pskr.Client cluster-elects a singleton via :global.register_name — all replicas start the GenServer but only one connects to MQTT; the rest stay in :standby and watch for the leader's nodedown to re-run election. Off in dev/test, on by default in prod (PSKR_MQTT_ENABLED=false as kill-switch). Pskr.Aggregator buffers in memory keyed by Pskr.path_key/1 and flushes every 60s via Repo.insert_all/3 with an additive ON CONFLICT (count summed, SNR envelope by GREATEST/LEAST, modes unioned via unnest+DISTINCT). Idempotent across overlapping flushes and across leader handover. Dockerfile sets BUILD_WITHOUT_QUIC=1 — emqtt's transitive quicer dep wants CMake + OpenSSL headers we'd otherwise have to add to the builder image just to never use QUIC over plain MQTT. Base image is unchanged; the new dep compiles cleanly into the existing prop-base runtime. |
