-`RX PHY` is emitted once per accepted LoRa frame before Reticulum decrypts or routes it. It is the broadest signal-strength record and includes frames that become announces, link setup packets, encrypted Link payloads, keepalives, or proofs. `RX PHY BAD` and `SIM PHY DROP` also include RSSI/SNR when malformed or intentionally blocked frames are seen.
+`RX PHY` is emitted once per accepted LoRa frame before Reticulum decrypts or routes it. It is the broadest signal-strength record and includes frames that become announces, link setup packets, encrypted Link payloads, keepalives, or proofs. `RX PHY BAD` and `SIM PHY DROP` also include RSSI/SNR and radio settings when malformed or intentionally blocked frames are seen. `SF`, `BW`, `CR`, and `TXP` come from the firmware build flags; transmit power is fixed by `LORA_TX_POWER_DBM` and is not dynamically changed by Exercise 205.
 
 The following `RNS...` prefixes are generated by the linked microReticulum tree when Arduino link instrumentation is enabled:
