Iran International TV is with unknown modulation on 11560/6270 kHz, November 26   
Wednesday, November 27 2019


re 6270 kHz 'Iran International TV' on Nov 27:

between 13.30 and 14.30 UT I played a lot of the direction finding TDoA
option on worldwide Kiwi net.

Used four locations of Kiwi SDRs:
Bangalore IND,
Hanoi VTN,
and Moscow-RUS.

Tried few times on sampling complete results around


never narrowed to Yerevan Gavar Noratus site,
which is far 2100 kilometers away westerly of Tashkent Uzbekistan.

6270 kHz S=9+35dB or -42dBm around 13.50 UT in Kuwait, southern Iran area.

from 0630 on 11560 ERV 100 kW / 100 deg to N/ME Farsi, fair, BUT without

The carrier swings at a very fast rate between 11560.2 and 11560.9 kHz. In
plain envelope demodulation the result is a kind of background growl/hum
while AMsynch fails completely.

Have you guys now abandoned the theory that the shortwave transmissions, in
this case generated by badly defective equipment, come from Uzbekistan
instead? Or is it even back and forth in their site usage?

At same time 11570 SIR 500 kW / unknown to WeAs Arabic VIRI IRIB PARS
At same time 11590 SIR 500 kW / unknown to WeAs NO AUDIO - OPEN

Around 1030 still a silent carrier on 11590 kHz. On 11570 kHz IRIB Arabic,
in synch with 15130 kHz whily they both were 2.5 seconds behind 13820 kHz
which went off at 1028 as scheduled. Seems that there is more to the "new
distribution strategie", as reported yesterday, than just making some
short-notice frequency changes two days ago and taking German off shortwave
after Dec 21.
