The meter points to ~70dBuV, strong signal, but the result is disappointing.

The signal is strong > 65dBuV but the results are disappointing. Tonight at the beginning seemed promising but in vain!

Strong signal. Erratic decoding ~1 min after the start up of the log. The rest result was almost perfect. After ~18:17 co-channel QRM affected the SNR.
