RRI 5940 kHz from Tiganesti

I got this transmission from RRI on 5940 kHz for 53 mins in English. Not very good decoding and only the L channel was listenable but the R was barely be heard.
As mentioned in their program schedule: "As of October 27th 2013 RRI broadcasts on new SW frequencies"

06.30 07.00 UTC 9600 kHz (DRM),
18.00 19.00 UTC 5940 kHz (DRM) and
21.30 22.00 UTC 6030 kHz (DRM)

The signal was strong so I got a very good result.

The overwhelming majority of my posted logs, since years ago, were using Dream1.6.1cvs.
For sometime now I use for testing Dream2.1.
I noticed that the SNR figures are somewhat different between the two Dream releases (seen on the attached plots) especially on estimating the max SNR figures. Dream2.1 seems that it needs more time to get the SNR changing values than Dream1.6.1. This leads to wrong figures by ~2.5dB or more.
Any explanations?

The results were perfect (max SNR >33 dB) until 18:37, then the signal dropped by 20 dBs and decoding problems started.

The results were perfect except of a short TX break down.

After 30 mins of almost perfect results at 18H30 the DRM signal dropped and low SNR affected the decoding.

A newcomer in this log. Strong co-channel QRM, all time long, destroyed the decoding, very bad results.

PS: I wonder if RRI monitors this website.
