Looks like they had some sort of switching issue this evening, either that or someone forgot the clocks and schedules had changed. At 1700 UTC the Romanian service seemed to go out on all the english service frequencies as well, both AM and DRM, and the DRM signal went off at 1730 instead of the more usual 1800 as it should have done.

Looks like a switching problem today, we're getting the Romanian service instead of the English service at 1700 UTC. Off abruptly at 1757 in the middle of a song.

Unusually for me I got a 100% decode today, the Tiganesti E3 transmitter must be a bit more reliable than the other old E1 model.

After about 17:34 the signal dropped by 10-15 dBs and fading had a severe impact to the decoding. ~90% CDA / 23.9dB max SNR.

Until about ~17:28 the results were almost perfect, then the signal dropped with severe impact to the decoding.
