Splatter +/-110kHz from 9735kHz?
 
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!

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!

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?

I just checked and did not hear the splatter around 04:00 UTC.

I noted DW went off the air for a minute around 03:59 UTC.

I have stations on 9625 and 9630 but nothing on 9845 and 9850.

DW is very strong at S10 on 9735.
