I see no intermodulation formula of
610 or 305 kHz minus/plus kHz apart distance
in nearby 31 meterband,
nor SOH, VoA or RFA CNR1 jammer object
by China mainland jamming security forces
on 8920, 9225, 9835 kHz channels. 

Receiver overload 
would be surprising in Brazil for these transmitters.
why not, 
dark propagation path at 13 UT across Pacific to/from China,

origin of 500 kW powerhouse from Xian bcast center site ?
when you use 57 meters antenna length ?
tremendous load into Yaesu FRG 8800 rx unit ...

Yes, I meant to say transmitter mixing product, but didn't find a 
suitable combination among Baoji-Sifai frequencies. Receiver overload 
would be surprising in Brazil for these transmitters.

If not on purpose transmitting on 10140, this could be a
transmitter site mixing product of two transmitters
in the 31 meterband.

Re Spurious or rather overloading his receiver gear ?
Daniel told the DX world a lot of spurious images in past weeks
in rage 10000 to 11000 kHz,
and told to IARU bandwatch etc. too
so my rather guess
his receiver configuration
of older Yaesu FRG 8800 receiver set,
and much extreme antenna gear length
trend to   O V E R L O A D  his equipment in use.
With easy access to various SDR server nets like Perseus, KiwiSDR and
SDRconsole, Twente etc. worldwide,
I could never REALIZE his such reception signal examples.
Decades ago the DXer world publized often similar IMAGES phantasies
of cheap receivers with lousy signal selection of the
IF x 2 = 900 / 910 kHz away of real fundamental basic frequency origin.

Hi Daniel,> as we agreed with Zach Liangas, the language sounded best
Tibetan and now I find it // CNR11 Tibetan 9530 kHz, so could be a
spurious mixing product from Xi'an site.
