Downlink Freq RX2 // 869.525

TTN indeed uses 869.525 with SF9 and 27 dBm high transmission power for RX2, and in the early days preferred RX2. However, nowadays it prefers RX1:

We try to avoid RX2 if possible. For RX1 we have 8 channels available, while RX2 is fixed on 1 channel and a very inefficient data rate. Therefore, expect most downlink messages to be sent after 1 second.

RX1 uses the same settings as your last uplink, and regular 14 dBm transmission power. So, despite the title of your post, I assume you’re seeing RX1 in the last two examples above (and indeed RX2 in the first example).
