Simone, could you merge this thread with http://www.drmrx.org/forum/showthread.php?t=2231 or delete mine, please? Thank you! I'll try to receive SWR in the next days.

A weak signal here in Hessen about 160 km North of Obereisesheim, with 17 dB MER just good enough for decoding with daytime conditions, interference getting stronger now as it gets dark.

A few ripples in the graph at the beginning, perfect decoding from 0435 with daytime conditions.

Surprisingly reliable reception at daytime continued today, although signal strength and MER are just at the minimum where it should work.
@ Marcel: I think that´s normal, you need about 17 dB to decode this transmission.

daytime ok, nighttime useless.
many audiodropouts on transmitter side while log is 100% - disruptions in audio-feedline?
Btw: Wanted to do unsupervised 5day-log over long weekend, but after 2days dream 1.7.5 crashed and pc ran at 100% CPU for the remaining three days

Some audio tonight from Obereisesheim, the AM station on 711 kHz was very strong after 2303 UTC and killed DRM decoding.

TX distance is wrong in this log.

Same picture as last week:
daytime ok, nighttime useless.

This time I used Fhg SWR 4.0.40 which obviously is not fully compatible with DRMcalc so I had to do a lot of manual editing ...

Btw: since around an hour or so the transmitter is working again ...
