3505-3509 is totally useless in Europe (at least West Europe, but probably a
larger part of Europe) during our evenings, due to a very strong what I
think to be utility station, transmitting intermittent streams of data
(sounds a bit like pactor) packets.

Too many DX-stations and DXpeditions are still using these frequencies,
their signals being interrupted/disturbed, resulting in frustrated EU DXers (and we all know what happens if some of those can't hear a station well).

Wouldn't mind if someone distributes this info to other related reflectors
(topband still the one and only I subscribe to), the more the better.
