Almost perfect reception - no drop-outs but the guard interval is exceeded on virtually every symbol. Note that the Dream decoder software is more generous with the SNR reading than the Fraunhofer software. For a Mode B broadcast the guard interval is 5.33 mSec.
Above is the minute by minute reception log, below is a symbol by symbol analysis of SNR v delay.

This guard interval violation (> 5.33 mSec) suggests reception of BR5akt is via multiple hop propagation.
