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.

What radios are you using? My guess would be some sort of IF problem.
If
both radios use the same IF then it could be overloading the circuits
and causing the problem. Some radios can cause symmetrical splatter (as
you put it) on both sides of the main freq, usually 910 khz below and
above.

That's actually a good point. I wonder if the radios' proximity to
each other could be causing an issue as well? If the IF's are off, it
could be a case of intermod by injection, but that is so rare as to be
a long shot.

Hope he does get back to us on what he finds.

Both radios are DX-394's. The 910 kHz offset signal would be a 2nd IF
image
on one side only, and would be carrier with sidebands, not carrier-less
splatter. The splatter is there with only one radio operating so it's not
radio interaction. I sent a message to DW - we'll see if they reply or it
clears up!

Cool! Let us know what happens. Are you still hearing it? Like the
next day after? If so, it seems hard to believe that the DW relay
station would not be aware of it, but you may save them some real
embarassment if you call their attention to it. Good on ya, Tom!

Two days in a row and not on any other station this evening. The 9735kHz
broadcast schedule from Bonaire is 0200-0600UTC. I'm hoping someone else
will check for splatter at 9845 and 9625, too. It's 01:51 UT now - I'm
standing by...

There it is again - 3 days running. Interestingly, Bonaire transmits on 9845
almost up to 0200 but the 9735 transmitter is on with carrier only before
0200 and before 9845 shuts off so it's not the same transmitter. The
splatter is a little easier to detect tonight at 9850 and 9630 due to other
stations coming in tonight on 9845 and 9625. Does anybody else hear it?
