Noticed this last night and tonight. Is it my radio or are others hearing
the same thing? German language transmission booming into Toronto at 9735
from 0200 with distorted splatter around 9845 and 9625kHz.

So it is Deutsche Welle transmitting from Bonaire. The splatter is
unintelligible but synchronised with modulation peaks, especially strong
with deep male voices. There is no carrier that I can detect at the splatter
frequencies and SSB reception mode does not derive anything intelligible.
The splatter spectrum seems fairly wide although the presence of adjacent
stations renders these observations difficult. I can't think of any receiver
overload or intermod process that would result in symmetrical splatter but I
am using two identical radios to listen to the 9735 program and one of the
splatter sidebands so there could be a common receiver problem. There is
less interference to the splatter on 9845.

DW could be having a gross tuning problem. Most tx'ers are
automatically tuned from presets unless they happen to be solid state.
It's possible they may have had a malfunction in the disciminator that
tunes the selsyn motors that tune the caps, or one of the tuning belt
slipped, but you would think they would catch on quickly to that.
It's happened to us at VoA before.

The other possibility is that their final tube in that tx'er (assuming
it's not solid-state) is about to throw craps. It could very well be
detuning itself enough to throw out that garbage.

If I read your post correctly, I doubt it's a receiver issue since you
appear to be hearing it on both. If it doesn't happen again the next
day, you probably can safely assume that DW had a problem and just
didn't catch it promptly!
