    The signal seems to be a bit low for accurate reading, but yeah it seems overmodulate slightly the last time I checked it too. It still is probably on the limits that Traficom has set here though, which allow peaks 10% of the time between +/- 75-100kHz, and 0,5% in +/- 90-100kHz. It may never exceed +/- 100kHz. There are still some stations that exceed these limits quite a bit, especially some temporary ones I have seen, which don't seem to have proper limiting for the audio.
    It is very important to stay under the +/-75kHz limit since many DSP based radios will not play well with overdeviation, like skipping the station during auto tuning. This has happened here back when 98.4 YLE Radio Suomi had bad overmodulation, many tuners just skipped the station even in stronger areas, and AF preferred distant ones instead.

      Looks like you're relaying something on 89.7 after 20:00 and until 8:00.
