Radio New Zealand (RNZI) back on DRM

Just noticed that Radio New Zealand has started transmitting digital radio using the DRM system again. It's the best DRM signal I can get here. So far very patchy decoding for me, the picture to the right is about the best signal I've got so far.

My receiver is a DRT1 controlled via serial from the Dream software.

As I write (approaching 6pm AEST) the signal is improving and I'm getting a signal to noise radio of 20dB sometimes which gives perfect decoding.

Update: It's 9pm AEST and I'm getting perfect decoding with 28dB SNR. Changing "Time Sync Tracking" to "First Peak" seems to improve things for me.
