It's worse... I think Pmbo's may be triggered by by non-pactor qso's on "their" frequency. I did sometimes notice a pmbo qrm'ing a drm-sstv or Digi-Voice qso when no winlink-client was present. Did someone else notice this too? Despite what winlink intrest groups are endlessly repeating, pmbo's are fully automatic stations with no operator input. I think it's important to clarify this fact.
